"...succeeds admirably in making the case for the philosophical significance of the Lysis, a dialogue which has suffered from dismissal and neglect. ...their book is philosophically provocative and engaging. It will be of vital interest to all scholars of Plato; parts of it will also be of substantial use for philosophers working on moral psychology and, in particular, on love." --Bryn Mawr Classical Review, 11/2006
