This collection of essays explores analogous issues in classical and modern philosophy that relate to the concepts of person and human being. A primary focus is whether there are such analogous issues, and whether we can find in ancient philosophy a notion that is comparable to "person" as understood in modern philosophy. Essays on modern philosophy reappraise the validity of the notion of person, while essays on classical philosophy take up the related questions of what being "human" entails in ancient ethics and psychology, and whether we should regard ourselves as, essentially, human or rational beings.
