The nature and existence of time is a fascinating and puzzling feature of human life and awareness. This book integrates interdisciplinary work and approaches from such fields as physics, psychology, biology, phenomenology, and technology studies with philosophical analyses and considerations to explain a number of facets of the perennnial question of time's nature and existence, both in contemporary and in its initial classical Greek context; and it then explores and explains two of the most influential investigations of time in classical Western thought: Aristotle's, as presented in his "Physics," and the (neo)Platonist Plotinus' in his treatise "On Time and Eternity." Original interpretative perspectives are argued in both cases, and special attention is paid to Plotinus as partly responding to and critiquing Aristotle's account.

Michael F. Wagner, Ph.D. (1979) in Philosophy, The Ohio State University, is Professor of Philosophy at the University of San Diego. He has published extensively mainly on aspects of Plotinus' Neoplatonism including Neoplatonism and Nature (SUNY, 2002) and in the Cambidge Companion to Plotinus.
