Does the fact that many non-human animals have pituitary disprove Cartesian Dualism?

So, you are a rationalist rather than an empiricist? You think that the more our philosophy looks like the Euclid's Elements, the better? Well, I am telling you, that way of thinking is useful in geometry, but almost everywhere else though, it leads us nowhere.

Some arguments for fish not feeling pain are "It appears as though type-c neurofibres are necessary to feel pain, because people with congenital analgesia have a smaller proportion of the type-c neurofibers. And fish have little or no type-c neurofibers." and "Fishes with a hole in their fin continue swimming as normal.". Completely empirical, not trying to rationalistically define pain.

I can be either an empirical rationalist or a rational empiricist. You choose.

But, given the whole ‘do fish feel pain’ thingy, I’d have to come down on the rationalist side, since there’s no empirical way to know how the fish feels about it.

Oh, really? The empirical fact that fish with a hole in their fin continue swimming normally doesn't suggest that they don't feel pain? Or the empirical fact that they have little or no type-c neurofibers which human beings need to feel pain?
