Socrates's Move Away From Individuals

Aristophanes's speech shows us that these lovers get some kind of temporary rest bite, but whether they really achieve happiness in fulfilment is not at all clear. If we take that point on board, then i think socratess move away from individuals as proper objects of the desire for happiness is really a laudable one. So what it would be to be happy is, say, to know what beauty is, yes? Is there anything we can say to make that more plausible, or is plato just sort of nutty, and does he havit?
