Griswold, Charles L. Jr., Self-Knowledge in Plato's Phaedrus, New Haven: Yale University Press, 1986.

Excerpt:

The Phaedrus presents the appearance of a tapestry that has come partially unraveled into a tangled skein of themes and images. The warp and woof are Socrates and Phaedrus, a pair so ill matched that their relationship strikes us as comic. Their exchanges seem thoroughly permeated by irony and playfulness, and composed of little more than storytelling and wishful thinking. So recondite is the Phaedrus’ design that the dialogue, like a colorful but poorly patched quilt, has been considered too thin to warm the interest of the serious scholar.
