ABSTRACT
The recognition of Galen’s importance in the history of ancient philosophy has been one of the most significant developments in Galenic scholarship over the last forty years. It has revealed his enormous debt to Plato, visible not only in his teleology and his theory of the tripartite soul and its three locations in the body, but also in his summaries of the Platonic dialogues and his literary reminiscences throughout his writings. At first sight, the works that Galen included in the catalogue of his writings under the heading of philosophy fit happily into such modern categories as methodology, logic, philosophy of language, epistemology and psychology. Central to all Galen’s activities was his interest in logic, of which he was a remarkable exponent. In his autobibliography he lists some forty-five tracts on logic, as well as a further twenty-seven dealing specifically with the ideas of Plato, Aristotle and the Stoics.
