For many of these people, science and religion simply deal with different realms. Science deals with natural causes for natural phenomena, while religion deals with beliefs that are beyond the natural world.

I think scientists are too quick to diffuse the religion vs science arguement. Maybe religious scientist can enlighten me on this. When one bases beliefs on essentially nothing ('gut feelings', apparitions, what someone wrote down 1000 yrs ago), how do you reconcile the use of evidence for establishing belief in one domain, and then not require this in another? We have absolutely zero credible evidence of a creator, an afterlife, or Santa Claus. Pick your religion, what method do you use to evalute it's 'factualness' vs some other religion? Usually the answer is that it's what you were first exposed to. This world would be much better off without the concept of an afterlife. Focus on the here and now, it's all we get.


> how do you reconcile the use of evidence for establishing belief in one domain, and then not require this in another

It's even worse than that. For religious scientists, often belief is directly contradicted by the evidence at hand. The reason this still somewhat works is because humans can exist (and sometimes thrive) in a state of profound cognitive dissonance.

I don't remember right now who said this first, but the phrase "religion poisons everything" comes to mind. Like a trojan on a computer, religion fortifies the brain against external influence. Most insidiously, religion poisons the ability to freely reason about data specifically and the environment generally. If there is such a thing as a poisonous meme, this is it. To use a biochemical phrase, religion has evolved to competitively inhibit the brain's logical and moral facilities, and in doing that it has developed heavily optimized strategies for maximizing infectiousness and resilience.


This pathologizing of religion is too self-serving and deserves some skepticism.

For one thing, it lacks a sufficient explanation for the scientific/mathematical contributions and intellect of people with religious/supernatural belief; people such as Donald Knuth, Isaac Newton, Adam Smith, Euler, Pascal, and so on.

For another, it conflates beliefs with mental habits. The point with empirical science, or math, or any other such discipline is the adherence to a set of intellectual practices rather than a particular set of conclusions that may (or may not) result from employing those practices.

Now beliefs are important, but at least for empirical science the usual criteria is that a belief be held only insofar as it is useful. Holding to the Physical Causal Closure (PCC) principle can be quite useful for investigating natural phenomenon, but plenty of intelligent people have been willing to break from it when they think it will help explain other aspects of life.

Of course, the PCC principle is not the result of research in empirical science, but rather its beginning. It is itself a philosophical, pre-scientific thesis, and should be dealt with as such. Incidentally, it is because of observations like these that Positivism is no longer a widely accepted philosophy.

Lastly, it is frankly uncharitable. What's more likely, that most of the world is brain-damaged and/or mentally stunted, or that you are oversimplifying the issues?


It may be due to the advancing night here in Germany, and I don't mean to insult you personally, but this seems like an uninteresting discussion to have about things that can be readily looked up and/or reasoned about without me doing a lot of pointing.

Nevertheless: it's possible for a scientist to be completely wrong about most things, and yet produce valid scientific theories. Only when superstition and science collide directly, work usually suffers. Otherwise cognitive dissonance works pretty well. You also have to keep in mind that historical figures had a different cultural outlook than we do today, and I'm boring myself as I write this.

Uncharitable may well be a fair charge, I take it. Other things that don't rank high on my list of credibility indicators are: the number of people believing something, and the social authority of the people believing it. This is all incredibly obvious historical baggage we're carrying around from a time when the goat was the pinnacle of technical achievement. However arrogant this may seem to you, I think a bit of brutal honesty is in order.

However, having said that, I'm fully aware that no amount of argumentation can convince a believer (see my other comments on how religion closes that avenue after it infects a brain). I'm sorry if all that sounds pompous, arrogant, or just plain stupid to you.

At a very fundamental level, religious and secular people might never be able to have a meaningful discussion about the nature of the world. It's probably for the best that we usually maneuver around these black holes on HN.


>At a very fundamental level, religious and secular people might never be able to have a meaningful discussion about the nature of the world. It's probably for the best that we usually maneuver around these black holes on HN.

There are better places for such discussion. However, I consider it a general rule that in all hangouts for intellectually curious people, if you flippantly say something controversial, expect to be challenged.

>However, having said that, I'm fully aware that no amount of argumentation can convince a believer (see my other comments on how religion closes that avenue after it infects a brain). I'm sorry if all that sounds pompous, arrogant, or just plain stupid to you.

I am not primarily arguing to convince you, but for the benefit of observers who are not as personally involved in our exchange. Besides, I think you are probably a thoughtful and intelligent person, and as such I would not expect you to be convinced of something over the course of a debate. Rather, if you did change your mind it would be on your own time and after much reflection.

I am sorry, however, that you believe religion is a incurable mind virus. Perhaps if you did not believe as you do, then you would take a different approach with your arguments.

>Other things that don't rank high on my list of credibility indicators are: the number of people believing something, and the social authority of the people believing it.

This, in and of itself, doesn't make you any different than a conspiracy theorist. I don't mean to say that you are one, and I don't necessarily hold authority or consensus very highly myself, just that rejecting them doesn't tell me much about your rationality. Regardless, my point was not that you should believe something because a lot of people, some of whom were pretty smart, also believed it. More about my actual point below.

>Nevertheless: it's possible for a scientist to be completely wrong about most things, and yet produce valid scientific theories. Only when superstition and science collide directly, work usually suffers. Otherwise cognitive dissonance works pretty well. You also have to keep in mind that historical figures had a different cultural outlook than we do today, and I'm boring myself as I write this.

OK, my point: cognitive dissonance is a pretty different phenomenon from infection by a memetic parasite. Your claim was that religion "has evolved to competitively inhibit the brain's logical and moral facilities" and that it "poisons the ability to freely reason about data specifically and the environment generally". If people with religious belief were so inhibited in their logical facilities, and could not freely reason about data or the environment, we would not expect them to be able to make mathematical, scientific, or technological advancements. They clearly have, and they continue to do so despite the cultural outlook of today (Knuth, for instance, is still alive).

Furthermore, when I talk about the large number of people who are religious, I am not saying "it's silly to think so many people are wrong"; I am saying "it's silly to think so many people are mentally handicapped". Especially since so many of these people are able to contribute to business, the arts, the sciences, etc.

Now, I am not saying that you are stupid, or handicapped (Indeed, your HN profile and web site indicate the opposite). Just that your thesis is bad psychology.

>I think a bit of brutal honesty is in order. You will find that, in this, we are in agreement.


The people you mention came before the theory of evolution. I doubt any of them would be believers if they had that info.


I don't like this outlook because it's too close to "ignorance is bliss" theme.


Pardon me for not getting this, but how can what I wrote be interpreted as "ignorance is bliss"? Shouldn't the conclusion be the opposite of that?


I may very well be the one not getting it (english is not my first language and I am sleepy at the moment).

Allow me to try to rephrase your explanation: it states that religion act as a kind of shield for the brain[1] (this is bliss) while at the same time blinding him to hard facts[2] (this is ignorance). Did I read too much in your explanation or summarized too much ?

[1] external influences

[2] the ability to freely reason about data specifically and the environment generally


No, that is sort of what I meant to say, except that I would never use the word bliss for describing the state of a host brain. You could argue about the meaning of ignorance, but I really don't think this catch phrase fits well with the statement I tried to make. Competitive inhibition is a more apt term for what's actually going on.


Ah, yes! It just hit me. [Here was an incoherent rambling from someone who really should go to sleep]. Your explanation fitted my biased model but I focused on my beliefs, not yours. My mistake, sorry. Don't know if I made much sense, really sleepy now :]

On a related note, I remember Dawkins spoke about memes and how ideas can be seen as some kind of virus that are subject to evolution.


I'm willing to talk about it on your terms, you don't have to bend to my mental models. I just don't have enough data yet to reason about yours ;)

> On a related note, I remember Dawkins spoke about memes and how ideas can be seen as some kind of virus that are subject to evolution.

I haven't read his books yet, but this stands to reason. Memes share a lot of characteristics with organisms, and humanity has built a great eco system for them in recent years. The first time I realized that ideas are actually evolutionary programs was in the 90s when I read Neal Stephenson's Snow Crash.


    how do you reconcile the use of 
    evidence for establishing belief 
    in one domain, and then not require 
    this in another?
Scientists regularly believe in a theory, or concept, that is not yet proven. Many scientists spend their entire lives proving something. Hence, I wouldn't suggest belief in science has historically relied on evidence or proof.

Now onto the main point, the difference lies with what is provable and what isn't. Many religions believe in a being that is not provable. Or believe in teachings for the betterment of society. These aren't provable or disprovable theories (whether you believe that is their nature or they are intentionally designed that way!) There are religions where one of the central tenets is that science and reason must be in agreement with the religion itself.

Personally I think the two can be seperated, and the problem only comes when religious leaders preach science. Religion, for me, covers a set of unprovable concepts.

I also wouldn't say people are too quick to diffuse the science vs. religion argument, I think pg has a few comments on what causes flame wars! (And a rather excellent essay relating to labels / identity [1]).

[1] - http://www.paulgraham.com/identity.html


I think most of these arguments would go away if people understood some probability theory. "It's just a theory", "It hasn't been/can't be proven/disproven.", etc.

The point is do you think it has a greater than 0.00001% of being true? How can you possibly justify such a high probability estimate? In the space of millions of possible hypothesises, the probability of any one being correct is incredibly small. Especially with Occam's Razor, simple explanations are far more likely to be true. And religion is a very over-complicated explanation.

We use evidence to rule out explanations which can't be true, or more accurately lower their probability (the evidence could just be a coincidence or a fluke, for example.) To raise the probability of a specific religion being true, you would need a lot of evidence. Which simply doesn't exist and in fact we have lots of counter-evidence (things that religion say that turned out to be false for example.)

Scientists do spend their lives looking at things that haven't been proven, but they have to have to think they have a greater than, say, 10% chance of being true to be worth their time.


It sounds like you feel there is an inherent conflict between science and religion (or am I misreading). I see no reason why this needs to be the case. Once you move beyond explanations for things that can make testable predictions, then you are out outside of science you have moved in to philosophy. At that point all explanations that don't contradict what is observed become equally valid/invalid.

Take for example the question more general question of whether or not there is a creator behind the universe. There is no real way to prove, or at least no one has come up with a way to do so, whether or not this is the case. As a result, either answer is equally valid/invalid.


Science is far more than "testable predictions" and covers an entire method that we have found to be the best and only way to understand reality with timid certainty. Science itself is basically a subfield of epistemology and it ties together both WHAT we know and WHY we actually know it instead of simply believe it. Science is dedicated to finding out what reality is (as best as mathematics or other abstract structures can describe it at least) and that sets up a class of rigor for certainty which religion can simply not touch. Also, built into science is a feedback loop that constantly reevaluates what it means to be certain and tries to tie that certainty to the real world through engineering, which, again, religion cannot even begin to attempt.

What we call science today is a formalization of what humans have been doing for tens of thousands of years: looking for patterns and relationships in cause and effect. The very act of making the first wheel, paper out of papyrus thousands of years before the lumber industry, or a calendar by looking at the stars is an act of scientific exploration that probes not just the natural world, but how we discover what the natural world really is. Over time that methodology has included into our cultural knowledge things like gravity and horticulture while excluding things like rain dances and homeopathic medicine.

In the end, you either accept the rigor and structure on knowledge and certainty developed by science and the scientific method (which, by the way, created modern civilization as you see it today) or you don't. If you accept it, religion by its very definition (supernatural and all that) conflicts with science. If you don't, then there is a basic difference in core assumptions and there really is no argument.


I agree completely with your first two paragraphs. I'll even buy the first sentence of your last paragraph. However, I fail to see why religion inherently conflicts with science. It is in no way clear that the scientific method can be applied to everything. Religion, or one of many other arbitrary philosophies, can fill in the parts that science does not cover.

If you start with the hypothesis that the universe was constructed by a conscious creator, how do you address that scientifically? As far as I can tell, the answer is, you can't.


You can't start with the hypothesis that "the universe was constructed by a conscious creator" until you have some clear evidence that such a hypothesis is warranted. This is where science conflicts with religion. If you're going to say something exists, or that a certain event or entity caused an effect, you have to prove it. Just because we do not yet understand multiverses (or whatever is out there) and what happened before the big bang, just because we do not yet have sensors to see beyond the scope of space-time, does not let any self proclaimed philosopher fill in the gaps with whatever they happen to read from the nearest religious text.

It doesn't matter whether you call yourself a theologian, philosopher, or scientist, if you're going to make an assertion or assumption, you have to back it up. If you don't, you operate outside of the human body of knowledge that can be confirmed as true, or even remotely accurate.


That doesn't make sense. Once you have clear evidence of something, it is no longer a hypothesis. You can start with any hypothesis you want. Of course if you expect something to be treated as scientific fact you need clear evidence. Until you get clear evidence, it is a matter of philosophy, and you can fill it with anything that doesn't contradict the known facts.


I didn't say evidence of the hypothesis, I said "evidence that the hypothesis is WARRANTED" which is a very big difference. If apples don't fall from trees and matter is not attracted to other matter then the gravity hypothesis has no evidence for it to even be considered! We see apples fall and planets orbit and matter attracting other matter and so we think, there must be something there! So we investigate and only after much testing do we say that the hypothesis is scientific fact within the bounds it was tested.

>> Until you get clear evidence, it is a matter of philosophy, and you can fill it with anything that doesn't contradict the known facts.

NO YOU CAN'T. Why? Because the nonsense ("philosophy") you fill it with STILL REQUIRES EVIDENCE when you claim that something positively certainly EXISTS such as a creator of the universe. You can claim you HYPOTHESIZE that there exists a creator, but it is on YOU to prove that a creator exists, not on anyone else to disprove it, especially when the scientific body of knowledge, both theoretical and experimental, shows no evidence and no sign of a creator outside of humans projecting their own desires.


If a hypothesis doesn't contradict the known facts, how do you determine if it is warranted?

You only require evidence if you expect others to believe the same thing. I'm not arguing that anyone should believe in any religion. I'm arguing that a scientist can hold religious beliefs without conflict.

> the scientific body of knowledge, both theoretical and experimental, shows no evidence and no sign of a creator outside of humans projecting their own desires.

This seems like it would strongly depend on who you ask. I'm not even sure how you would come up with a criteria for this (although maybe that is just limitations in my own imagination).


This I think it the best comment in the (what I found to be very interesting and fruitful) discussion. I'll be thinking more about what I see as an inherent conflict between science and religion, but thanks.


Yes, but as a scientist I see no reason to believe in some specific unprovable concept over any other. I find Christian believe as arbitrary as Muslim believe as arbitrary as anything else I can come up with. So how could I believe in any of them?


Yes, it is arbitrary. Believing that there is no creator to the universe is also arbitrary. That is because, science, as it currently stands, has nothing to say about the matter. Picking/not picking any religion is a matter of philosophy, not science.


Talking about creation is one thing, but these religions bring a whole host of other things into play as well that you cannot ignore.

There is no evidence for any of the rest of it, no evidence of interference by gods, no evidence of any real communications either. So saying you think the universe was created by [a conscious entity?] a god is entirely different than saying that you believe in a particular religion and all its narratives and usually inherent contradictions.


I agree that for many people belief in a particular religion can bring in a bunch of associated dogma that is at odds with science. My point is that it doesn't have to. Dismissing all religions just because some people do feel that way is throwing the baby out with the bathwater. Not every christian is a young earth creationist.


>As a result, either answer is equally valid/invalid.

I posted a similar comment above, but this completely misunderstands probability theory. If you can't prove something 100% true or 0% true there is still an inbetween more than "equally valid or invald." Something could have a 0.00001% chance of being true or a 99% chance of being true.

In the space of all possible explanations, the chance of religion being the correct one is exceedingly small. Especially if you consider Occam's Razor that simpler explanations are more likely to be correct. Religion is a very over-complicated explanation.


Wait, how does probability factor in to this. What is meaning of a 30% valid argument in this context? If you can't prove something, it doesn't mean that the answer is probabilistic.

I'm not interested in if any particular religion makes sense or doesn't make sense to you. My point is that the the debate over different religions is at its core a philosophical argument not a scientific one. A point you confirmed by making a philosophical argument against religion rather than a scientific one.


Probability applies to everything. I'm not going to buy stock in some company just because I can't "prove" it won't go up by 5,000% tomorrow. The scientific method is just a special case of probabilistic reasoning where you try to get so much evidence that your probability estimate is very very close to 100% or 0% (but it's still never completely certain. The evidence could have been faked or just a coincidence, or there could be a better theory out there that also explains the evidence, etc.)

All beliefs are just probability estimates of how certain you are that they are true. If you are very certain of something then you must have a high probability estimate that it is true. If you aren't certain then it must be lower. If you say "I'm 90% sure this will happen." Then you should expect to be right about 90% of the time you say that.

If what I'm saying isn't intuitively obvious or if you just want to learn more, read this: http://yudkowsky.net/rational/bayes/

In any case the idea that religion isn't disprovable is completely false: http://lesswrong.com/lw/i8/religions_claim_to_be_nondisprova...


I understand that statistics are an important tool in 'proving' things scientifically. The problem is, you're making a philosophical argument against religion not a scientific one. Probabilistic solutions don't sense for philosophical questions. For example, what is the probability that P=NP?

The lesswrong article you linked to does not disprove religion. You certainly can disprove dogmatic ideas that have surrounded various religions, but that is not the same thing as disproving religion.

For example, what if I said I believed that the universe was created by a conscious creator? This is clearly a religious statement, but as far as I can tell there is no way this statement can be addressed scientifically.


>For example, what is the probability that P=NP?

I would say less than 1%. That is if you were to bet me $1 that next year someone will mathematically prove that, I would bet up to $100 that it doesn't.

I am not talking about statistics here but uncertainty. Probability in the Bayesian sense is just a measure of how certain you are of something.

I can't prove that the sun won't rise tomorrow. Even if we didn't have any scientific understanding of what the sun was or why it appeared to orbit the Earth, I still would bet at great odds that it would also rise the next day.

So what is the certainty that the universe was created by a conscious creator? Well we can look at all the possible explanations and assume they have equal probability. Then you can use Occam's Razor and assume that simpler hypotheses are far more likely to be true than more complex ones (and a god is a rather complex one as it has to explain the existence of an intelligent being with the power and desire to create universes.)

You can call this a "philosophical" argument or a "scientific" one, or something else entirely. Science is basically the same thing, assuming simpler theories over more complex ones, and assigning certainty to different theories.

Also there is nothing special about religion. All the same arguments would apply when talking about, say, the existence of an invisible pink dragon that resides in my garage. I'm guessing your certainty of that is rather low though.


That is a gross misunderstanding of both uncertainty and science. Uncertainty is based on measurements made. The 1% you came up with is an entirely made up number. Also, science is explicitly not about assumptions. It is requires testable predictions. The complexity of the solutions does not matter. Otherwise we would still be using Newtonian mechanics for everything.

The problem with your dragon example is that it is testable. This moves it in to the realm of science.


Science is merely a special case of Bayesian probability theory. You don't have to have evidence in order to assign a probability to something. In fact it's impossible to update probability estimates without already having a prior probability.

Anyways you can't say the invisible dragon in my garage is testable. Say you throw flour on it. I just say "maybe the dragon is impermeable to flour." You try to touch it. I say "It moved to avoid being touched." You listen for sounds. I say "it's a quiet dragon." Etc. This is similar to religions constantly changing every time some fact they claim gets proven false. I could always just say "the existence or non-existence of the dragon is outside the realm of science."

At the end of the day I still highly doubt you are going to believe there is a dragon in my garage. In fact I doubt you will accept even the tiniest possibility that there is a dragon in my garage. Well maybe tiny possibility but not worth considering. Not any larger than any other crazy idea people can come up with.

This is perhaps a very complicated way of reasoning back to the standard idea most scientists will tell you: "It's stupid to believe things without evidence" or "most theories turn out to be wrong."

As I said, religion isn't special. Everything here applies to it just as much as the dragon.

A good explanation of Bayesian reasoning: http://yudkowsky.net/rational/bayes/


Bayesian probability still requires data as an input or your result is meaningless. If you start with a made up value and update it with more made up values, you still have a made up value. You still haven't offered any explanation for how you were able to come up with a 1% probability that P=NP.

Your example still isn't the same as mine. Mine didn't involve goal post moving. For your example to be the same, you would have to start off with a dragon whose presence is not detectable in any way. What's the difference between an empty garage and one with an undetectable dragon in it? Absolutely nothing. I'm not saying you should believe in the dragon, I'm saying that determining the presence of the dragon is not done scientifically.


It is a made up number. So what? It's not made up out of thin air though. I should expect to be wrong about 1% of the time when I make such a prediction (and if I'm not it's because I was over or under confident, and should adjust my confidence accordingly.)

So where did the prediction itself come from? My brain, obviously. And that's not a bad thing. Humans are generally good at estimating probabilities. It is essentially what the brain evolved to do. This isn't unique to humans though, there are computer algorithms which can do similar tasks, and mathematical formalizations for calculating certainty.

You can and should be able to assign a probability estimate to anything. When you open your garage door you should expect not to see a dragon. You should be very certain that you won't, actually.

You can't not have any degree of certainty about something. You can expect something to happen. You can expect something not to happen. You can be slightly certain that something will happen. You can be moderately certain. You can think it might have just as good a chance as happening as it does of not happening.

But you can't have no idea what so ever how likely it is to happen. You have to have some expectation of how likely an event is to happen, you can't have no expectation at all.

There is no such thing as a "separate realm" where ideas can't have any certainty values of how likely they are to be true.

As for moving the goal post, religion has moved the goal post plenty. From perfectly testable predictions, to less testable claims, to claims that can't be tested at all.

If you are upset that I, personally, moved the goal post, then just pretend that it was my ancestors that claimed there was a dragon in my garage, and my grandparents decided it was invisible, and my parents decided that it was impermeable to flour, and now I believe that it is a completely untestable dragon, and have decided that dragons are not a matter that is testable by science, and that I've been completely consistent with this belief.


>It is a made up number. So what? It's not made up out of thin air though.

Wait what?

Yes you can assign a probability to everything, it doesn't necessarily mean anything, but you can do it. I hope that is not how you prove all of your math problems.

I'm sorry I must not have been clear in my previous post. I did not mean that you personally were moving the goalposts. I meant that your hypothetical person who believed in garage dragons was moving the goalposts. I was trying to argue that your analogy was a straw man argument.

Also, your argument that 'religion has moved the goalposts' Would be an example of an association fallacy: http://en.m.wikipedia.org/wiki/Association_fallacy


You are completely missing the point of the Bayesian interpretation of probability and I'm not really sure how to explain it any better.

Let's say you have to bet money on whether or not P=NP will be proven next year. You get to choose the odds you are willing to take it at, and you want to do it so that you will win the most amount of money on average. The on average is the important part.

So if you say you are 99% sure that it won't, that merely means you would make a bet where you will pay $1 if it doesn't happen, and get $100 if it does. If you made a hundred such bets and lost only 1% of the time, you would walk away with just as much money as you started with.

The point of the thought experiment is you don't get the luxury of saying "I don't know", you have to actually make a decision of how certain you are. And you can't take 10 years to calculate how certain you are mathematically either, you have to make a decision. And it's all probabilistic. You decide what bet to take based on how likely you think it is to happen. This is how we make most our decisions. We couldn't go about our daily lives if we didn't do this.

I don't think it's an association fallacy. I am not saying "All claims religions made in the past turned out to be false when tested, therefore all religious claims are guaranteed to be false." I was just trying to point out the history of religions removing more and more of the actual testable claims. Because the testable claims are all that's left, since everything else has long since been proven to be false.


It sounds like we are talking past each other slightly. It sounds like you are trying to produce the probability that a proof is found that P=NP in a given year. However, I'm asking for the probability that ultimately P=NP. What would you average that over? What would your input data be?

I understand that people work up all sorts of heuristics for their daily lives, but that doesn't constitute scientific proof. There still just heuristics.

> Because the testable claims are all that's left, since everything else has long since been proven to be false

How can testable claims be all that's left. If it's testable then it can be proven or disproven. Did you mean untestable?


I knew a few semi-religious scientists in the past.

They were all in line with what we'd probably accept as scientific reasoning behind natural phenomena, but deferred to religion on more philosophical (and not physical) questions: "Why are we here?" "What's the meaning of life?" "Why should I be good towards other people?"

(I know part of these are at least touched on by some of the humanities sciences - moral philosophy and psychology, but the scientists I've experience with were biologists & chemists and not as well versed in those fields as their own)


if they're willing to ignore huge swaths of divine text what makes the existential statements special?

if someone made a list of statements, most of which were false but some of which were unverifiable why would anyone accept, as truth, the unverified claims?

if anything accept part of the Bible, cherry picking, is worse (logically) than accepting all of it.


Ask yourself a few analogous questions:

- How can you vote for or otherwise support a politician if you don't agree 100% on everything with that politician?

- If your friend enjoys the same music that you do, but not the same food, would that necessarily make you not go to a concert with that friend?

- How can you enjoy a book written by an author if you strongly disagree with that author's personal beliefs? Do those beliefs necessarily invalidate anything and everything that this hypothetical author writes? As a real life example, take Orson Scott Card: do his personal views about homosexuality make his Ender books any worse?


if anything accept part of the Bible, cherry picking, is worse (logically) than accepting all of it.

I'm not sure I follow this... Why is this so bad. Let's say that my view of the bible is a set of self-replicating instructions that were carried through time as culture. Today I deem some ideas helpful parts of my culture, and some not to so helpful. I choose to follow the former. Is this logically inconsistent?


> if they're willing to ignore huge swaths of divine text what makes the existential statements special?

The idea that divine texts are a particularly privileged source of factual information is not universal among religions (or even among religions which have divine texts, or even among major branches of, e.g., Christianity.)


As I understood it, they were asking about religious scientists. Religious != take-given-entire-scripture-literally. It just means they believe in the existence of a higher power (if you can forgive my paraphrasing).

If they did mean scientists who take all of scripture literally, then no I don't actually know any of those.


I know religious scientists who are among my smart Christian friends: intelligent and nuanced people who are familiar with the atheist arguments and have actually read Dawkins and Hitchens and have actually read the Bible and know its history, and still believe. They're really nice people, and as an atheist and humanist that's what I do respect. (I like our local Church of England priest for the same reason: he really cares, and does actual work himself to make the world a better place - the local soup kitchen and so forth - and Anglicanism at its best is basically humanism with Jesus up front.)

That said, I've seen these sophisticated theists' faces when they walk into a local church (London E17) and realise that the congregation is basically one step up from the Pentecostals and sincerely believe that good things happen to good people, if bad things happen to you then you must be a bad person, and the world is probably 6,000 years old and flat, and that these are actually the people Dawkins was talking about in The God Delusion. I successfully refrained from smirking, 'cos I didn't want to be rude.


The realms have different rules. An argument within/for/against a particular religious belief, such as a gut feeling or reference to a religious text, doesn't work in science. In a similar way, it doesn't make sense to use the rules of science to support/refute religion. To assert that there is no evidence for a religious belief is essentially a religious argument, not a scientific one.


Even if there are different realms, I don't see how I (personally) can use different ways of reasoning in these realms. I'm quite certain that believing in some afterlife (as opposed to total oblivion after death) would make me much happier. But I cannot choose to believe something that is wrong or at the very least totally arbitrary according to my usual logic. It feels no different to me than wanting to believe that there is no massive government surveillance, even though I have followed the news for the past few months.


> how do you reconcile the use of evidence for establishing belief in one domain, and then not require this in another?

Religious belief is quite frequently based on evidence; it often isn't empirical evidence that is verifiable independently because it is grounded in personal internal experience, so it isn't the kind of evidence on which science works, but there is nothing inconsistent about:

1) recognizing empirical/scientifically-based beliefs and other beliefs as separate kinds of belief, and 2) preferring the empirical evidence in the domains for which it is relevant and available, but still 3) accepting other experience as the basis for non-empirical beliefs in areas where empirical evidence is not available (or even relevant.)

> Pick your religion, what method do you use to evalute it's 'factualness' vs some other religion?

Not everyone who has a religion is concerned with evaluating it against other religions in terms of "factualness".


Of course claims about an after life are based on faith, that's true regardless if the claim is that there is or is not an after life.


Not necessarily. If we can adequately explain not just life but the sensation of consciousness - that personal identity which is said to persist into the afterlife - in terms of physical interactions which terminate and decompose when the body dies, then strictly speaking it requires additional unwarranted suppositions to assume that this explainable and now terminated physical phenomenon persisted and continued to operate in some hidden spiritual world. It requires implicit rejection of Occamian world view.


I find it to be an interesting philosophical question, I've been quite affected by some ideas from logical positivism, specifically what a meaningful statement is and just how limiting that can be. Using Occam's razor to reason about the existence of xrays before they where observed would lead you to believe that they don't exist, and rightly so, I think as a scentific method it's very helpful.

I view the scientific method to be an instrument to gain knowledge with a common criteria for evidence, not something that represents absolute truth, which in my oppinion is not within reach outside of logic and maths and other self contained systems. But there is a trade off there, in that they by themselves can not produce anything but tautologies without empirical observations as a basis for the premises, unless you believe in synthetic a priori.


No, it would not. Anything that exists outside the universe and time is not subject to conjecture of any sort. Applying logic to such a thing is meaningless; there is no reason for logic to exist outside of the universe. In other words, absolutely nothing meaningful can be claimed about an afterlife (unless such a thing exists within this universe which seems doubtful).


What you are arguing is called mind dualism. It is subject to very many difficulties, and does nothing to resolve pesky issues like neurologically damaged and split brain individuals (what happens in their afterlife?) or explain why there is this magical correspondence between the spiritual realm and physical reality, without any causal connection (see my point about Occam priors).


Certainly any afterlife would necessarily be non physical, no? Alternatively, I would be delighted if you gave proof otherwise.

At any rate, I'm not arguing for mind dualism nor will I attempt to answer any of the questions you posed. I argue that it is completely pointless to speculate in any way about something which exists outside of the bounds of knowledge (science).

I was merely agreeing with the assertion of the OP:

> [faith is required] if the claim is that there is or is not an after life

An afterlife can not be shown to NOT exist even if consciousness if fully explainable by science. There is no special knowledge to be found in logic/philosophy that exist outside of science. Therefore, we only have faith in either case.


In the entirety of the human endeavor, everywhere we have looked the simplest explanation which explains all of the evidence has turned out to be correct. This Occamian world view has never failed us. Not once.

So yes, it would be quite a leap of faith to assume that there is some spiritual existence where our minds reside and which happens to line up perfectly with events in this this causal world. Doesn't mean it's wrong - this hypothetical modern version of the afterlife is cleverly constructed to be completely untestable from this side of death's veil. But it can be shown rigorously and mathematically to be a strictly more complex theory with precisely the same predictive power for this world (and with lots of odd answers when questions are pressed).

It's like positing epicycles for the motions of the planets. Personally I just find it easier and more satisfying to believe the Earth moves. I adjust all the other collected knowledge Occamian reasoning, so why not this too? I don't like being a hypocrite.


The reason is because the entire history of the world can not be used for evidence for an afterlife that exists outside of the world. No knowledge or intuition (from this world) can be applied to something that exists outside of it.

>It's like positing epicycles for the motions of the planets.

The two are not at all related, unless one of us claims the hand of god or some other metaphysical force is moving the planets. Such a claim would not be testable and the same caveats would apply to it, too.

Your intuition could be correct, but how would we verify it? We have no experience with the afterlife. It is impossible to test this knowledge in any way (apart from dying but then communicating the results are the problem).

The only thing we can do is acknowledge the fact that we can not say anything sensible one way or the other.


I don't know the answer to this either, but I've seen this kind of compartmentalization in lots of very smart folks. I know a guy who's a brilliant optics engineer and has had success both in business and academia. He's not sold on climate change as a fact.


The fact that you used the word "sold" already implies to me its a matter of faith.

Climate change is a highly politicized and potentially corrupt push of an agenda. As Im not working on climate change or related sciences, all I can do is believe on what an alleged aggregate of scientist tell me, its pure faith.

Scientists and engineers are the new priests.


That's your opinion. There are plenty of people who feel that the concept of an afterlife is a very comforting one and would prefer to have it.

Unless you can prove that humanity is better off with statistical significance, please shut up about religion on hacker news! :)


The concept of an afterlife is appealing to me as an atheist, but that doesn't make it true. And that's really the core problem of religious arguments: wishing very hard for the laws of the universe to change doesn't make it so. Ever the technocrat, I would take that innate wish for an afterlife as an unconscious manifestation of the desire for humans to transcend their biological existence and move on to something better. And that's certainly something worth pursuing. But just sitting on a rug and insisting it's already an option, provided you adhere to certain mystical rules of course, now that's just unproductive nonsense.


See https://news.ycombinator.com/item?id=6524430 . What I would be interested in is to have a religious scientist explain how he can choose to believe (for example in an afterlife) against statistical significance. I for one can't shut down my way of reasoning when it comes to religion, no matter how much I would like to.


It's pretty darn easy to hold two seemingly-contradictory beliefs. The trick is to stifle the urge to resolve them.


>Focus on the here and now, it's all we get.

What proof do you offer?


As I see it, the basic flaw in the materialist worldview is this: http://plato.stanford.edu/entries/perception-episprob/

It is also what leaves the door open for more transcendent views. Eastern religions, in particular, are founded on the basic idea that your everyday experience is illusory.

You dismiss religious beliefs as based on "essentially nothing". In fact, the basis of religious belief in the most general sense is conscious experience. The kinds of conscious experience that you would probably call hallucinations. But, referring again to the link above, you are probably disposed to call shared perceptions "real", and non-shared perceptions hallucinatory. Religiously, metaphysically, or even philosophically minded people might call that arbitrary. Chauvinistic even. We act like consensual reality is real because it's convenient, intuitive, and seems to get us good results in consensual reality.

You say "zero credible evidence of an afterlife." That's true, if you restrict yourself to what's usually considered "evidence" in science. Evidence that more than one person can perceive at the same time. But individuals can go further if they really want to see whether there's anything to see. Are you willing to dedicate yourself to a meditation practice for a long time? Psychedelic drugs? Flatliners (the 1990 movie)?

I'm not recommending that anyone do anything dangerous. Just pointing out that there are things you can observe first-hand, that aren't likely to be replicated in a study.


> That's true, if you restrict yourself to what's usually considered "evidence" in science.

It's true that if you don't restrict yourself to the world of facts, you can do pretty much anything. And there are lots of contexts where I'm doing things decidedly not rooted in facts, such as enjoying and producing works of fiction for entertainment. However, if we're going to talk about the nature of the world, adhering to facts becomes mandatory. Otherwise, there is not a lot of meaningful exchange to have at all. Of course it's fun to kick hypotheses around - but a supernatural world view is usually not a mere hypothesis, it's a postulate made in conscious and willful contradiction to evidence.

For instance, I like Lord of the Rings, but the moment I insist people should take seriously my belief that orcs are under my bed, I have crossed the river into the land of delusion. Of course I'm free to entertain that belief, but people publicly calling it out as bullshit is not Chauvinism, it's an honest and rational response.


You seem to imply the religious belief is inherently contradicted by evidence. What evidence do you feel contradicts all religions?

For example, if a have a religion that only contains a single belief, that the universe is created by a conscious being. How do you produce evidence that contradicts that? I would argue that you can't because science can't address that. It is a purely philosophical question.


Most religious statements set themselves up to be unfalsifiable, and that's really the main trick behind most of these ideas, but to work they have to make certain claims about the nature of the universe that are exceedingly unlikely, or in other words: just completely made up.

The kind of evidence we gather through scientific observation points to a world that works completely without supernatural intervention, and with advancing scientific knowledge the kind of acrobatics you have to perform just in order to keep escaping the light radius of discovery become more and more elaborate, outright denial of evidence becomes necessary.

For example, to claim that the Earth is 6000 years old, you have to discard a lot of paleontological evidence. To deny evolution, or any other established scientific model, you pretty much have to make the conscious decision to ignore data. The way this works is usually by some invocation of all-powerfulness: my deity is all-powerful, so due to that it not only faked all the evidence, it also made itself invisible and undetectable.

I agree though that it's not possible to disprove arbitrary fantasies on their own terms. All we can do is measure and model things within reasonable limits. Far, far outside these reasonable limits, everything is theoretically possible, it's just not compatible with reality in any meaningful way.

From the perspective of a person on the outside looking into this religiously contaminated world, the most upsetting and depressing thing is that people know their beliefs are completely made up on a whim, and in full knowledge of how that process works, they still believe all this crap without an ounce of skepticism.


I feel like you are conflating two thing, religious belief and disbelief of scientific results. There is no reason that these need to be tied together. Of course science conflicts with the latter, but it says nothing about the former. Things that are not provable one way or the other are philosophy not science.


Late to the party, but I wanted to say, thanks for the interesting comment.


Reason rests on fictions, too. For example objects/things don't exist. But without believing in them it's impossible to function. Religion also has to be evaluated functionally.


Quite interesting. It corrects well the statement "Natural selection is about survival of the very fittest individuals in a population." to: Though "survival of the fittest" is the catchphrase of natural selection, "survival of the fit enough" is more accurate. http://evolution.berkeley.edu/evolibrary/misconceptions_faq....

I think that's a very important clarification, because we may look around and see very diverse population with very diverse handicaps - from mental to physical, and question how it could be that "survival of the fittest" let all this happen.

Information is also organized really well - short paragraphs, easy to consume, with links to more details in some sections. Target audience is probably someone who wants a few questions answered, but not a creationist or a biology scientist.


> Though "survival of the fittest" is the catchphrase of natural selection, "survival of the fit enough" is more accurate

Would it make sense to turn it around and say "Natural selection is about unfit individuals in a population dying off"


The most accurate way to phrase it would be to say that "natural selection is about less fit individuals having a decreased chance of passing on their genes."

Evolution is really about which genes are passed on to the next generation. Most of the population at any given time is going to be less-fit than the fittest (by definition). That doesn't mean they don't pass their genes on. While totally unfit people may not be able to pass on their genes at all, many, if not most, of a generally less-fit population will pass on their genes at least one generation. Depending on the quality of the mate they are able to obtain, their genes may not go further than the one generation, or they may keep going for many generations. On average, the less-fit genes will "die off" but this isn't always the case, for many reasons.


My favorite one is: Evolution and Creationism should be given equal time in education.

Not even the Catholic Church thinks Creationism should be taught (I'm Catholic if it matters) in school as science.

From Wikipedia: Here is viewpoint of the Vatican's chief astronomer, Fr. George Coyne, issued a statement on 18 November 2005 saying that "Intelligent design isn't science even though it pretends to be. If you want to teach it in schools, intelligent design should be taught when religion or cultural history is taught, not science." Cardinal Paul Poupard added that "the faithful have the obligation to listen to that which secular modern science has to offer, just as we ask that knowledge of the faith be taken in consideration as an expert voice in humanity." He also warned of the permanent lesson we have learned from the Galileo affair, and that "we also know the dangers of a religion that severs its links with reason and becomes prey to fundamentalism." Fiorenzo Facchini, professor of evolutionary biology at the University of Bologna, called intelligent design unscientific, and wrote in the January 16–17, 2006 edition L'Osservatore Romano: "But it is not correct from a methodological point of view to stray from the field of science while pretending to do science.... It only creates confusion between the scientific plane and those that are philosophical or religious." Kenneth R. Miller is another prominent Catholic scientist widely known for vehemently opposing Young Earth Creationism and Intelligent Design.


I'm not sure why "not even the Catholic Church" comes into play (is it the standards bar for forcing religious topics in schools?)

I'm from the bible belt of the USA, and I've only heard this from protestant christians (some of whom I'd use as the standards bar for the above).


>"I'm not sure why "not even the Catholic Church" comes into play "

Because is a religion with the same Genesis book on the bible and it's an example of at least one religion (the root of Christianity) that doesn't believe in teaching Religion as a science


> Because is a religion with the same Genesis book on the bible

But not the same view of the role of the Bible in the religion -- sola scriptura is a doctrine of the Protestant Reformation.


More from a historical Galileo standpoint of science vs religion.


It's only recently the Catholic Church has gone so nutso right-wing - in even recent decades they were heavy on the social justice, relatively speaking.


The current Pope is pretty progressive. Case in point that I read earlier today:

    "The Lord has redeemed all of us, all of us,
    with the Blood of Christ: all of us, not
    just Catholics. Everyone! `Father, the
    atheists?' Even the atheists. Everyone!"
http://seattletimes.com/html/nationworld/2021997332_apeuvati...


The Catholic Church (including its heirarchy) has always (at least, since it became established within the Roman State) included both factions that are extremely pro-elite and those that are extremely social-justice oriented, as well as everything in between.


>"in even recent decades they were heavy on the social justice"

They are still very active in social justice activity. At least that is very true in poor zones of Latin America


Yep. Even as an atheist and humanist, I am happy to commend Christians who do actual good for people :-)


I would point anyone who subscribes to any of the several current fad diets to this one: http://evolution.berkeley.edu/evolibrary/misconceptions_faq....



What fad diets are you referring to?


Any diet that is based on an unsubstantiated claim that "humans have not evolved to digest X" where X is something that humans have been eating for thousands of years. Paleo comes to mind, but there are others. The claim made by these diets isn't structurally invalid, but often the claims are made without any investigation and are substantiated by anecdotal evidence that people feel better when eliminating X from their diet. That's fine, but that's not the same thing as being incompatible from an evolutionary standpoint.


Perhaps Paleo, but I'm not the parent.


None of the evolution deniers that I've met would have the slightest interest in reading this list, but I suppose it's useful to quickly look up counter-arguments to their claims. A similar site with a greater focus on creationist claims can be found at http://www.talkorigins.org/indexcc/list.html


The vast majority of evolution deniers I've known wouldn't have the slightest interest, I agree. But, as someone who grew up totally immersed in an evolution-denying atmosphere, I would have been very interested during that time in which I was "seeking the truth." (And indeed I fondly remember from that time the talk.origins page you linked. Thanks for the nostalgia, what a great site!)


I don't think this is about convincing the "deniers" so much as curing misconceptions among the general public about how evolution works.

You don't have to be arguing from bad faith or cynicism to hold some of the mistaken beliefs listed. The stuff about phylogenies and how they relate to the "tree" graphs is particularly neat.


As someone who believes in both an intelligent designer creating the world, and micro (but not macro) evolution, I am extremely interested in reading this.

I just thought I would let you know :)


If you're genuinely interested in reading this and accepting facts that may challenge your beliefs, then I applaud you.

Here's some reading to get you started: http://www.talkorigins.org/indexcc/CB/CB902.html


Sadly, many would have little interest in having their perspective challenged at all.


"Faced with the choice between changing one's mind and proving that there is no need to do so, almost everyone gets busy on the proof." -John Kenneth Galbraith


No matter how it's explained, I still can't wrap my brain around how evolution produces complex systems. How do systems with interdependent processes and parts get produced by a process that seems to proceed stepwise?


You're a programmer, right? A lot of people on here are.

You know how when starting something completely from scratch, there is so much foundational work to do, making frameworks, helper libraries, classes, etc. You have to do all that stuff before your program can do much (assuming no third party libraries).

Well, once your code base (or just your knowledge of existing libraries) is advanced enough, you can more easily combine pieces of it with relatively small changes to the code. You can mix and match parts and the result will be something very complex that may be based on person-years worth of work while only taking a few minutes to assemble.

Pieces of code can be removed from the final product with a one line change. While the code still exists in the final product, it isn't referenced anywhere.

These are a couple of analogies that help me think about it. They don't explain everything, but it should be enough to make clear that just because evolution works by "stepwise" changes that doesn't mean one step can't create huge differences.


Thanks, that's an interesting way of illustrating it.


Complex organs have developed from simpler organs in a series of small incremental improvements, while the organ all the way have been fully functional.

Think of it like iterative developing a program by adding or modifying one line at a time, while still keeping the program runnable. You can start from a simple program and develop it into a complex program with this method, although it will be a very tedious and inefficient process compared to if you were allowed to rewrite multiple lines in one go. But evolution works in small increments.


If you add to your analogy that you have no knowledge of the existing codebase, and you have no idea what you're adding or modifying, then you understand my difficulty grasping the concept. Thanks for the reply though!


Maybe that is a fruitful way of looking at it. Take evolutionary algorithms, for example (http://en.wikipedia.org/wiki/Evolutionary_algorithm).

Essentially you start with a random program and iterate on it using an evolutionary model. The point of these algorithms is precisely that an understanding and knowledge of the code base is not required. All that's necessary is some way of measuring the program's fitness for a task.


Right, but if you had _billions_ of years, you could still write an amazing program, even if you have no knowledge of the codebase and no idea what you're modifying.


Billions of years running trillions of experiments in parallel.


Exactly. The time scale is one of the most important parts to swallowing evolution on an intuitive level.


Well, my point was that it is not just time, but also the massive parallelism. Both combined is just such a phenominally mind-bogglingly large amount of exploration.


Complex systems can originate from simple environments. If you're mathematically inclined, I invite you to read Wolfram's book "A New Kind of Science", it does a great job of showing processes like this, for example with cellular automata. The key take-away is that complexity isn't necessarily the product of an even more complex birthing mechanism, but that complexity can and does frequently arise from simplicity, a notion most programmers should be familiar with as well.

> How do systems with interdependent processes and parts get produced by a process that seems to proceed stepwise?

Slowly, and in very small steps. Not every step produces a "useful" change, either: most mutations are fatal, the rest is by and large neutral.

The initial biosphere was relatively simple, but after hundreds of millions of years, the system has grown huge and complex.

You can visualize evolution by imagining a search space, being explored by a myriad of different configurations (of organisms or machines). Configurations that survive, survive. The others are filtered out. Surviving configurations get to explore more of that search space and the process repeats. Over time, this leads to some pretty neat architectural advances (but any biochemist will agree there's a lot of horrible, unfixable spaghetti code in there as well).

We only get the impression of very high complexity and lots of interdependent processes because we look at a very mature ecosystem. Things would be easier to grasp if we were restricted to looking at very early microbes. The principles are the same, though.


Thanks, I'll check out that book.


The Evolution of the Eye (2010) - Richard Dawkins http://www.youtube.com/watch?v=mb9_x1wgm7E

Also an interesting take on it is that, although complex, a lot of organs and systems are actually designed rather poorly.

http://www.youtube.com/watch?v=AN74qV7SsjY http://en.wikipedia.org/wiki/Argument_from_poor_design


Let me let you in on the little secret.

When you are backed into a corner, you accept whatever is left to explain the complexity at hand. Then you pretend that you understand it. Collect enough these "understandings" of complex stuff and you will be able make analogies between them or even offer "little secrets" for the uninitiated.


So, nothing exploded and created everything? How come?


You're at least asking the question at the right level. Most people get bogged down arguing about how the something that already was became different stuff that was. "Why is there something and not nothing at all?" is an excellent philosophical base to start building a cosmology on.


I was just thinking this when I read your comment. It is probably the largest thing that is holding me to my faith in an a God.

Whether or not evolution is true, it explains _how_ our world was created, but not why.


Just remember science is about what and how, when you get to stuff like why, it's philosophy. 90% of all of the ridiculous arguments that seem to happen around this subject appear due to the inability to keep these separate.


Science doesn't care about 'why' questions. It is also misleading, because it assumes that something has a purpose, which is not necessarily the case.


>It is probably the largest thing that is holding me to my faith in an a God.

How does the existence of a God explain the absence of nothingness? Infinite regression, and all of that. That is one of the things that would keep me away from a faith.


Maybe there is no "why". The world is, no reason, at least nothing we could ever understand.



Publishing a long list of misconceptions is a really bad way to destroy them. Readers will skim and just remember the headlines, all of which are false statements.

Spread facts, not "myths"


It depends who the audience is. Most individuals I've known who hold these misconceptions wouldn't have bothered going to that page in the first place. So they're not the audience.

I am at least part of the audience by definition. I'll admit that I started with a skim of the list of headlines. I then read in detail on the misconceptions I hadn't heard before. I'm now familiar with these misconceptions and can more clearly articulate a response when I encounter them.


> Spread facts, not "myths"

I think this guy [1], with his PhD thesis on the topic, would beg to differ.

Also, I don't think the website's sole purpose is to destroy them (misconceptions/people?). Some of us lay people who are knowledgeable, but have learnt the wrong factoid, for one reason or another, could still benefit from it.

[1] https://www.youtube.com/watch?v=cY_o4A1wzsg


Yeah. I haven't had time to read the list (I plan on reading it later, ) but the tone from the intro didn't seem to be concerned about destroying people.

I'm personally in the camp of folks that picks up information about evolution as I go, since it's not really related to anything I do in my day to day, and I appreciate a concise description of possible misconceptions.


You need the myths for SEO.


The biggest misconception about evolution is shared both opponents and proponents.

Most often the discussion is about whether evolution is true or not.

Evolution is not true. It's not false either and any discussion about it being that is missing the point.

Evolution is the best model we have to explain how life and species interact and evolve.

There are no finite answers in evolution, only observations of phenomena. But those observations best describe the biological world.


Evolution is not true. It's not false either and any discussion about it being that is missing the point. Evolution is the best model we have to explain how life and species interact and evolve.

I think you mean that the "theory of evolution via natural selection" is the best model we have to explain the observed phenomena of evolution. Analogous to the Newtownian theory of gravity explaining the mechanics of observed terrestrial and celestial gravity. Gravity and evolution are simply there, how they occur requires a theoretical explanation.


The "theory of evolution via natural selection" is itself another (very common) misconception about evolution. Don't equate evolution with natural selection; they are far from synonymous. In fact, we have good reason to think that most evolution is non-adaptive.


I wouldn't say it's observed; no one has observed billions of years of evolution. That's why there is debate. Please don't compare to the observation of gravity; it's not even comparable.


Nobody has observed gravity either, only its effects.


Nobody observed the effect of evolution.


Evolution is simply the change in allele frequency in populations of organisms over time. This is most certainly observable.


That is by not metrics what evolution simply is.


The present-day biosphere is an effect, as is the fossil record and DNA relations between species.


That does not prove evolution the way gravity is proven.


How so? Evolution is just change in populations over time with common descent, and that's pretty well demonstrated through the things I mentioned, about the same as gravity is demonstrated by things falling. What's different?


I've never seen it demonstrated definitively through the fossil record. There are a lot of assumptions and best-guesses leading back to common ancestors.


I've never seen gravity demonstrated definitively either. Sure, they say that there's this force that makes stuff fall, but I've seen plenty of things go up instead of down when released.


That is farcical. If something is thrown in the air, you can demonstrate the force of Newton's constant, thereby definitively demonstrating gravity. Actually calculating the gravitational constant with precision is the only difficulty there. Nothing about this is assumed. Which back to the point, is nothing like the assumptions of hereditary lines in the so-called "fossil record".


I've had a party balloon on my ceiling for the past month. Clearly there are some holes in this "gravity" theory of yours.


Evolution is observable.


I think it is comparable. We do have the fossil record, after all.


That does not allow you to conclude that evolution is true the way that you can conclude gravity is true/factual.


perhaps yes and no.

Gravity is a force you can measure, make experiments with and validate.

You can use the scientific method to invalidate gravity. You can't do that with evolution and therefore you can't compare the theory of gravity with the theory of evolution the way I see it.

But I might be wrong.


This experiments show the evolution of bacteria that become resistant to antibiotics in laboratory :

http://v6.tinypic.com/player.swf?file=24goih4&s=6


It is not (self evidently) true that evolution correctly models the origin of adaptations.[1] That is, the menu-creation ex ante selection is a "black box" model, and that is at best problematic, from a logical/mathematical/and "scientific" perspective. The randomness hypothesis is almost surely wrong here (as the mechanism of menu selction).

[1] http://evolution.berkeley.edu/evolibrary/misconceptions_faq....


I detest evolution. Beings suffering, trapped in limited bodies and minds, forced to kill for survival and plagued with diseases. It's horrible that a person's quality of life relies on the results of a silly genetic lottery. It's a cosmic joke, I tell you.

What have these creatures done wrong to deserve such ridicule?

http://wtfevolution.tumblr.com


> "Bacteria, HIV, malaria, and cancer have evolved resistance to our drugs."

Honest question... if HIV is a virus, and virus are not living forms [1], how can they evolve? In that case wouldn't be the host cell the one that evolved?

[1] http://www.virology.ws/2004/06/09/are-viruses-living/


> Honest question... if HIV is a virus, and virus are not living forms, how can they evolve?

The requirements for evolution are a subset of the requirements for "life", so its quite possible for things that are not alive to evolve.

> In that case wouldn't be the host cell the one that evolved?

Viruses can be a source of variation in the genetic code of living things that contributes to evolution in the living things, but that's a different effect than the evolution of the virus itself.


Evolution does not strictly apply to living organisms. Natural selection, which is what I think your referring to, as a mechanism for evolution relies on Mendelian inheritance. The only requirement for Mendelian inheritance is genetic material (DNA or RNA), which viruses obviously have.


No, because the host cell is generally used to produce more viruses and is then lysed to release them. HIV and other retroviruses use RNA to inject DNA strands into the host cell's nucleus where those new genes instruct the cell to produce more viruses. Even if the host cell splits, the genetic machinery is still there for the virus to reproduce.

Either way the end result is a bunch of new viruses each with their own genetic code that could have mutated.

AFAIK whether or not viruses are living organisms is the equivalent of programming language religions in biology and is quite controversial. I personally look at viruses as living organisms and consider "viral reproduction" amongst sexual and asexual reproduction.


Evolution is about replicators. Living things tend to be replicators, but not all replicators are living.


Yeah, but if humans came from monkeys, why are there still monkeys? I bet you can't answer me that.

(cough)


And the related question: If God made man from dirt, why is there still dirt?


O noes, you have just disproven biology!


There aren't monkeys anymore, that's just a lie Big Nature Documentary is trying to push down our throats. Have you actually seen a monkey outside a carefully staged "exhibit" at a zoo? If you believe that, you probably believe that magicians can conjure a rabbit from a hat.


Humans didn't evolve from monkeys, humans and monkeys share a common now extinct ancestor.

Or it was aliens.



oops. I just couldn't resist...


Well, as far as I am concerned it is a simple matter of people not being intellectually prepared to understand the theory. I am not saying this to be elitist. Not at all.

I had a conversation with a guy at a xmas party last year. I don't have a clue how we went where we went but we ended up talking about how "human wizards" can figure out the position of the moon every day and write an app to show you. To this guy this was no different from magic. There is no way in the universe that anyone is going to make a good case in favor of the theory of evolution to this person until he elevates himself a few rungs in the educational ladder. That's just a fact.

What about scientists who claim to believe in creationism? For the most part I see it this way: If you are a nobody scientist with no hopes of becoming anyone at all, what is the easiest way to become someone? Thank you Jesus! I've met and have spoken to a few such "scientists" who, for example, teach at religious schools. You can see right through them. They are virtual gods within those organizations. They are elevated to prestigious standings within that community. They are held as proof that someone crossed the proverbial isle and, by the way, he is a honest-to-god scientist. No, they are not. They are business men. And quite smart if you ask me. If you don't see an upshot to your scientific career, go to a religious university and proclaim you've seen the light. They'll have you writing books in short order.

Then there are guys like Ben Carson, the ex-Johns Hopkins surgeon republicans are parading around. The guy is obviously very smart yet he is religious to a ridiculous degree. I like a lot of his ideas. The problem is that every third sentence is about religion. I don't know much about him so can't really opine beyond saying that people who are constantly praising god and talking about how everything is preordained and that they are god's tools, etc. scare the crap out of me. Not a huge step from there to Iran. Is he playing a mental game because of his political aspirations? Maybe. Republicans need to realize they are loosing a huge chunk of the population for putting the bible in front of everything they say and do. I digress.

I am looking forward to the lecture [0] at Caltech on the 20th given by Richard Dawkins and Michael Shermer. Should be interesting. Anyone going?

There are two funny things:

- Evolution itself is pretty much outdated theory. Genetics, biochemistry and ethology are light years beyond Darwin. It is like discussing Copernicus while scientists are working on quantum gravity.

- Evolution does not disprove creation and vice versa. God could use evolution as a tool. And God could also create Earth with all those fossils underground just for a joke. :-)


None of these things are funny or true for that matter.

> Evolution itself is pretty much outdated theory.

Evolution as an abstract model is pretty old, but it's not likely to ever be outdated. To this day, it describes accurately what is going on with any kind of adaptive system, not only in biology but also computer science and information theory, and one could make some convincing arguments for physics as well.

> Genetics, biochemistry and ethology are light years beyond Darwin.

It's true that Darwin didn't necessarily know much about the inner workings of what he was observing. All he could do is make the actual observations, and reason about them. This led to a key idea about how organisms develop, and it is this idea that became part of the basic tool set of any scientist, it's right up there with Pythagoras and Newton. Genetic and biochemical research didn't really exist in Darwin's time, but the principles he described are found everywhere you look in these fields. And if it hadn't been for Darwin, someone else would have found this out, it became gradually more inescapable the more data we gathered. In fact, today it wouldn't be called much of an achievement at all, since the mechanism is so obvious and ubiquitous whenever you look at bio data.

> - God could use evolution as a tool. And God could also create Earth with all those fossils underground just for a joke.

Those two are actually somewhat mutually exclusive. Either you believe that some kind of deity "uses" evolution as a tool, at which point people should ask themselves what the point of having gods is if they're not actually doing anything measurable at all.

The second point, although you meant it as a joke, is actually harder to argue with - because it leaves reason so far behind it becomes difficult to have any meaningful discussion about it at all: there is nothing in principle to say against the argument that our whole environment and history could be manufactured. We would have no way of knowing that, in fact there would be no way of knowing the actual age of the universe. It could be 2 seconds old in that case. All we have to reason against this approach is an argument from plausibility and Occam's razor.


>>Those two are actually somewhat mutually exclusive. Either you believe that some kind of deity "uses" evolution as a tool, at which point people should ask themselves what the point of having gods is if they're not actually doing anything measurable at all.

That is the most basic methodological problem with Intelligent Design. The claim is that there are gaps where "intelligence" injects itself into the evolution of living things. The funny thing is, every gap is very well hidden and looks exactly like the result of evolutionary processes and builds on the same design patterns that have already been established.


> Evolution as an abstract model is pretty old, but it's not likely to ever be outdated.

But it is outdated. Survival of the fittest is gross oversimplification and it is holding back more complex theories, which could provide better results. Wanna explain how virus interacts with human body? Forget chemistry, you will have to butcher your theory with terms like 'fittest', 'parasite', 'species' and so on. Otherwise nobody will understand it and nobody will publish it.

Anyway, I do not live in America, I do not even believe in god, I just find this debate ridiculous.


When scientists today talk about evolutionary processes, that's very different from the way "survival of the fittest" is crammed down the public's throat with animal documentaries and the like.

> Forget chemistry, you will have to butcher your theory with terms like 'fittest', 'parasite', 'species' and so on.

I'm not sure what you mean by that. Like all fields of knowledge, bio sciences adhere to a certain lingo consensus to express ideas. In some cases, an eventual expansion of the original meaning is inevitable, but if anything I'd actually accuse many science papers of doing the opposite (creating new expressions where none were needed). There is no butchering going on in respect to evolution as a process, though of course there are ongoing conversations about the forces and sub-processes going on in nature. But just because our models aren't complete that doesn't mean we don't have a pretty good idea of what's going on in general. Especially in molecular biology, the theoretical advances and the amount of raw knowledge has been nothing short of staggering in recent years.

> Anyway, I do not live in America, I do not even believe in god, I just find this debate ridiculous.

That makes your original comment all the more puzzling, I guess. Your post sure seemed to have a religious background.


What do you mean by "outdated"? Scientific theories don't go off with age, they depend on evidence and the scientific evidence continues to point to evolution as the best theory. Modern biology might be more advanced than it was in Darwin's day but nothing's disproved the fundamental ideas. That's like saying that the discovery of the Higgs boson makes the Earth orbiting the Sun obsolete.

And as for your second point, it's true. God could use evolution as a tool. God could hide fossils as a joke. God could just be having fun by letting us build up our quaint little theory of evolution before suddenly dumping a herd of unicorns in the savannah. God could, if he existed, do pretty much anything for any reason completely incomprehensible to us. And that's precisely where creationism falls down as a scientific theory - any flaw is just covered by "maybe God did it just because" and it can't be disproved.


Scientific theories do go off. They should also provide predictions and explanations of unknown events. In modern biology even term 'species' is pretty much outdated. Same way we no longer use Newton equations for space navigation.

BTW: Earth does not orbit around sun. It orbits around center of gravity, which is not even inside Sun.


The same difficulties with identifying individual species today were faced by Darwin in the Origin of Species. That is in fact exactly what the title of the book refers to.

>>BTW: Earth does not orbit around sun. It orbits around center of gravity, which is not even inside Sun.

The center of gravity of the sun-earth system is most certainly inside the sun. If it wasn't, the sun would perceptively move as the earth orbited it.


The center of gravity of the entire solar system (the solar barycenter) wanders around and is currently located inside the star. It will be outside of the sun in 2017.

Jupiter, Neptune (edit: and Uranus) serve to create a giant spirograph.


"Evolution itself is pretty much outdated theory."

No, it is not. It continues to bear rich fruit to this day.

Actually, since Darwin's conclusions in On the Origin of Species remain largely intact to this day, their age makes them better, not worse.
