The Nature of Life: Classical and Contemporary Perspectives from Philosophy and Science Edited by Mark A. Bedau and Carol E. Cleland Bringing together the latest scientific advances and some of the most enduring subtle philosophical puzzles and problems, this book collects original historical and contemporary sources to explore the wide range of issues surrounding the nature of life. Selections ranging from Aristotle and Descartes to Sagan and Dawkins are organized around four broad themes covering classical discussions of life, the origins and extent of natural life, contemporary artificial life creations and the definition and meaning of "life"¬ in its most general form. Each section is preceded by an extensive introduction connecting the various ideas discussed in individual chapters and providing helpful background material for understanding them. With its interdisciplinary perspective, this fascinating collection is essential reading for scientists and philosophers interested in astrobiology, synthetic biology and the philosophy of life. Mark A. Bedau is Professor of Philosophy and Humanities at Reed College, Oregon and a regular Visiting Professor at the European School of Molecular Medicine, in Milan, Italy. He is an internationally recognized leader in the philosophical and scientific study of living systems and has published and lectured extensively on issues concerning emergence, evolution, life, mind, and the social and ethical implications of creating life from nonliving materials Carol E. Cleland is Professor of Philosophy at the University of Colorado (Boulder). She is a central figure in the emerging science of astrobiology and has published in major science as well as philosophy journals. Her research focuses on issues in scientific methodology, historical science (especially earth and planetary science), biology (especially microbiology, origins of life, the nature of life, and astrobiology), and the theory of computation).
