Metaphysics of Shape and Color How many shapes are there in the universe, and how many colors? A standard answer is infinitely many in both cases. This answer is not incorrect, but it doesn’t go deep enough. Metaphysically, we want to know how many irreducible shapes and colors there are. As a matter of basic […]
A Proof of Platonism I am going to prove that the universal whiteness is not identical to the class of white things. The proof is similar to the well-known proof that pain is not identical to C-fiber firing.[1] Thus: I can think of whiteness apart from the class of actual white things; I can conceive […]
Car Evolution Suppose a particular car is designed and built. No other car is created. The car is then copied by technicians multiple times over many years, say one thousand. Errors in the copying are sometimes made, resulting in a car slightly different from the original. Suppose a million new cars are built, so many […]

They denied my request (without explanation) and told me they would charge me for every day I went over the announced date. I therefore […]
Evolution by Nutritional Selection Animals need food. They cannot survive and reproduce without it. They therefore have adaptations that ensure that enough food is consumed: traits that enable them to find food and consume it. This is not selfishly confined to the individual animal; animals also procure food for their young, often going without themselves. […]

This doctrine runs into trouble with things you know but have not perceived—concepts of the unperceived. It would appear to imply that you can’t have concepts of, and knowledge […]
