The Theetetus of Plato. By the Rev. Lewis Campbell. (University

Press, Oxford.)—An able and scholarly edition of this important dialogue. Mr. Campbell, in addition to copious notes and a marginal abstract of the argument, has prefixed an exhaustive introduction, in which he discusses the relation of the dialogue to the contemporaries of Socrates, to the earlier theories of Heraclitus and Parmenidos, to Aristotle, and to philosophy in general. In short, this edition loaves the student of Plato nothing to desire.
