If perfect rationality doesn’t exist in general, then if you want to assume it, you have to prove that a relevant class of problems has a perfectly rational agent
That’s not what your other post argues. It argues that perfect ratioanlity doesn’t exist in a specific world which is fundamentally different than our own. You haven’t shown that there are prolbems in our world for which perfect rationality doesn’t exist.
If you want to make a deductive argument based on a bunch of abstract axioms you actually have to care about whether the axioms apply.
+1. Thanks for this feedback, I’ve edited as follows:
“If perfect rationality doesn’t exist in at least some circumstances(edited), then if you want to assume it, you have to prove that a relevant class of problems has a perfectly rational agent.”
The point I was making is that you can prove for a large class of real world problems that such a rational agent exists, so most things remain the same, except for the fact that you have to add an additional line in your proofs quoting a general result that proves a perfectly rational agent exists in the particular type of situation.
