Do humans have purposes and values? Michael Ruse, after a lifetime's quest for understanding,' concludes yes.' In this book, he journeys from Plato and Aristotle, through St. Augustine and Kant, to Darwin. The exploration is scholarly and profound, as well as eminently readable. There is much to learn from On Purpose and much to relish while reading it.--Francisco J. Ayala, University of California, Irvine ukryj opis
