Selbstbewegung und Lebendigkeit

What is the definition of that which is named"soul"? Can we give it any other definition than that stated just now:"the motion able to move itself"?" (Laws 895e). The essays in this volume touch upon the central theme in Plato's late dialogues of the soul as the principle of self-motion and vitality. They discuss in particular the soul's relation to the intelligible world and understanding, as well as its cosmic and socio-political dimensions.
