“Philosophy always buries its undertakers.” Philosophy comes to life in every generation, not only because each generation has its distinctive problems, but also because the genius of the great minds of the past is pertinent to our current concerns. This book applies the thoughts of the great philosophers to medical ethics problems like Transplants, Abortion, and Euthanasia. It compares the visions of Plato and Aristotle with those of the Buddha, Confucius, and with Darwin, Freud, and Nietzsche. It compares Judaism, Christianity, and Islam, in the face of contemporary atheism. It concludes with maps of the ancient, medieval, and modern philosophical worlds, and shows the relevance of the past when dealing with our current most appalling problems.
