Other than a class on logic, all of my other courses involved enormous amount of written argumentation, e.g., reasoning, ancient philosophy, modern philosophy, Asian philosophy, philosophy of mind, philosophy of science, philosophy of film, metaphysics, etc. I would say that only logic had a direction connection to computer science, although as a computer scientist, I would choose to write essays about the Turing test, philosophy of AI, etc. This was 15+ years ago, but I assume things are still the same in many philosophy departments.
