Brann, Eva, "The Tyrant's Temperance: Charmides," The Music of the Republic: Essays on Socrates' Conversations and Plato's Writings, Philadelphia: Paul Dry Books, 2004, 66-87.

Excerpt:

Let me here bring in the subtitle of the Charmides. We don’t know who supplied it, but it is quite accurate: “Concerning Temperance: Tentative.” The dialogue is certainly tentative; it makes an unsuccessful try at discovering the meaning of a term and seems to have purely negative results. But just remember how useful negative results are in all sorts of investigations: they tighten the confines of the positive possibilities.
