Diotima’s ladder: does loving the Form of Beauty make particular people disposable?
In the Symposium (210a–212a), Socrates reports Diotima's account of the ascent of love. The lover moves from one beautiful body to all beautiful bodies, then to beautiful souls, to practices and laws, to kinds of knowledge, and finally to Beauty itself.
Gregory Vlastos argued in a well-known 1969 essay that Plato's lover loves people only as bearers of beautiful qualities, never as individuals. On that reading the beloved is a rung you step off.
But then Alcibiades crashes in, drunk, and gives a speech about loving one specific, maddening, irreplaceable man: Socrates. Martha Nussbaum, in The Fragility of Goodness, reads that speech as Plato deliberately setting a counterweight against Diotima.
I'm not sure which I believe. Is Plato aware of the cost of the ladder, or is Alcibiades simply a warning about what happens to people who never climb?
