Humans are actually intuitively log scale thinkers. That is, humans without the kind of early arithmetic training that Westerners get will think more in terms of ratios than differences. There are theories it is more evolutionarily adaptive.
Isn't it also related to our physical perception? Both hearing and vision at least have somewhat logarithmic properties (e.g. response to point-source brightness, and hearing frequency response)
