Full Idea
The people who make the best deliberate choices do not seem to be the same as the ones who form the best beliefs; on the contrary, some people form better beliefs but because of vice choose what one shouldn't.
Gist of Idea
The best beliefs need not produce the best choices, because vice can intervene
Source
Aristotle (Nicomachean Ethics [c.334 BCE], 1112a08)
A Reaction
This is a more careful account of why Aristotle disagrees with Socrates on akrasia. The intellectualism of Socrates implies that making the best choices largely consists of forming good beliefs. Wickedness is ignorance.
