One concept named after this philosopher was analyzed by Jaakko Hintikka, who used doxastic logic to argue that contradiction is at the heart of that concept's absurdity.

That concept, goodness, could not be equated with concepts such as survival or pleasure since that leads to the prescriptive naturalistic fallacy.
