The tripartite division of Mosaic philosophy into ethics, physics, and epoptics, mentioned in Stromateis 1.28.176, corresponds to Clement’s project of Christian philosophy, as outlined and partly pursued in that treatise. Clement integrates this division, obviously inspired by a Platonist model, into a larger programme of Christian education, adumbrated in the Paedagogus, whose first, pre-doctrinal part is practical. By doing so, he creates, within the context of the church and—arguably—its catechetic school in Alexandria, a coherent and powerful alternative to other similar programmes on the religio-intellectual market of his time.

Overview of the main issues in Galen's scientific epistemology , the state of the art, and the contents of this volume.

The chapter discusses two texts designed to throw into sharp relief Galen’s methods of solving natural and dialectical problems. The first comes from the treatise The Mixtures and Powers of Simple Drugs (SMT), and deals with the power and nature of olive oil. Galen castigates one Archidamus for having arrived at a mistaken account of oil’s nature, because he has generalised from a limited set of observations of questionable relevance. In contrast, Galen proposes an orderly course of inquiry, which starts from the complete account of the oil’s observable attributes and proceeds towards causal investigation by means of their empirically testable ‘differentiations’. The second text is Thrasybulus, subtitled Whether Hygiene Belongs to Medicine or Gymnastics (Thras.), and the chater shows how Galen sets about answering that question in a quasi-dialectical manner. The first step is the discovery of an agreed starting-point, consisting of a relevant and non-question-begging description of the point at issue. This is followed by further conceptual clarification of the agreed description, which, as the chapter argues, plays a similar role in the dialectical dispute as ‘differentiation’ of observed attributes in the former case.
