AD> The volume presents essays on the philosophical explanation of the relationship between body and soul in antiquity from the Presocratics to Galen, including papers on Parmenides on thinking (E. Hussey, R. Dilcher), Empedocles' Love (D. O'Brien), tripartition of the soul in Plato (T. Buchheim), Aristotle - especially the Parva Naturalia - (C. Rapp, T. Johansen, P.-M. Morel), Peripatetics after Aristotle (R. Sharples), Hellenistic Philosophy (C. Rapp, C. Gill), and Galen (R. J. Hankinson). The title of the volume alludes to a phrase found in Plato, Aristotle and Plotinus, referring to aspects of living behaviour involving both body and soul, and is a commonplace in ancient philosophy, dealt with in very different ways by different authors.
