One of his fundamental assumptions is that anyone who knows what is good will choose it. Why would anyone deliberately choose what is bad? When it’s put like that, this doesn’t sound so paradoxical. But we do think, don’t we, that people deliberately choose things even though they are bad? Maybe even because they are bad, given the perversity of human nature? For Socrates this idea was absurd. For him, something’s being “good” obviously implies that it is worth choosing. So for someone to think that something is good is for them to think it worth choosing.
