The physicist who states a law of nature with the aid of a mathematical formula is abstracting a real feature of a real material world, even if he has to speak of numbers, vectors, tensors, state-functions, or whatever to make the abstraction.

... causes (pains) are not logical constructions out of their effects (behaviour).

No sane person should believe that something is subjective merely because it cannot be settled beyond controversy.

It was Rudolf Carnap's dream for the last three decades of his life to show that science proceeds by a formal syntactic method; today no one to my knowledge holds out any hope for that project.

I think part of the appeal of mathematical logic is that the formulas look mysterious - you write backward Es!

Cut the pie any way you like, "meanings" just ain't in the head!
