The essays in this volume treat a wide variety of fundamental topics and problems in ancient Greek philosophy. The scope of the section on pre-Socratic thought ranges over the views which these thinkers have on such areas of concern as religion, natural philosophy and science, cosmic periods, the nature of elements, theory of names, the concept of plurality, and the philosophy of mind.

The essays dealing with the Platonic dialogues examine with unusual care a great number of central themes and discuss them in considerable depth: problems in language and logic, myth, reason, hypothesis, eros, friendship, reason, morality, society, art, the nature of soul, and immortality. In addition, they offer fresh discussions on a number of basic morphological, methodological, and philological issues related to philosophical arguments and introduce new aspects for a critical reexamination of controversies surrounding the doctrines and the authenticity of certain Platonic works.

The essays on the philosophy of Aristotle are closely reasoned analyses of such basic themes as the universality of the sensible, the nature of kinesis, the problem of future contingencies, the meaning of qualitative change, the doctrine of phantasia, the essence of intelligence, and the metaphysical foundations for the ethical life.

The essays on post-Aristotelian developments in ancient philosophy offer challenging and well-documented discussions on topics in the history of ancient logic, categorical thought, the ethical doctrines of ancient Scepticism, epistemological issues in the physical theory of the Epicureans, and basic concepts in the metaphysics of the neo-platonists.
