The Socratic Paradox

Plato's theory of recollection might be socratic, it might not. It looks as though he had some fairly radical ideas about virtue and value. So there was a thing that used to be known I think no longer is as the Socratic paradox which is the paradox that says that no one does wrong willingly. But why would he think that knowing something is in itself a motivation to do something? The only reason we do the worst thing or the wrong things is because we have really got our heads in a paper bag and we don't know what on earth we're doing.
