The volume discusses important chapters of Platonic philosophy, including its pre-Socratic origins and later developments. It particularly focusses on the relationship between Plato's logico-semantics and his metaphysics. Plato's linguistic views are deeply rooted in the Platonic metaphysical system, and vice versa. The strong connection between the two and its development into the Middle Ages form a major subject of this volume. Other themes featuring in this book are Plato's philosophy of nature, his epistemology, his theology, his cosmology, as well as his conception of the soul and his philosophy of art.
