Abstract
According to the canon of Thrasyllus (see D. L. 3.59), Plato’s Laches is about cour-age and employs, to borrow a term from Theaetetus 149a–51d, an ‘obstetric’ method, in which the ideas of Socrates’ interlocu-tors are delivered into the light of day and examined. These Thrasyllan labels correctly identify the simple theme and tactic of the La., but as with all of the Socratic dialogues, apparent simplicity disguises enormous sub-tlety of structure and composition. One thing that seems hidden from most readers is the special relation between theme and tactic, namely that the practise of Socratic dialogue requires and exhibits courage in examining what one really thinks.
