The prologue of Clement's Pedagogue is re-examined against the backdrop of the divisions of ethics in Philo of Larissa, Eudorus, and Seneca. Apart from shedding light on the prologue as a project of practical ethics, new observations about Seneca's terminology are made and a hitherto unnoticed parallel in Strabo adduced. Turning to Stromateis II 2, 4-6, the paper argues that it plays the role of an introduction to theoretical ethics, which covers the rest of the extant Stromateis, being designed for the sake of prospective teachers of Christian doctrine.
