There is a reasonable urgency today about clarifying the relationship between biology and human affairs. A growing genetic technology is an obvious reason for concern. But behind that is the real crisis, at once ethical and educational. The “moral” teachings that descend from the new scho~ls of biology - of which sociobiology may be considered representative - are easy deductions from rigid reductionist theories, requiring no inquiry about the limits of theory, and thus ready for popular consumption. Arnhart clearly recognizes the philosophical dimensions of our situation in his article “Aristotle's Biopolitics”. His suggestion that we begin our rethinking of bioethics with serious study of one of the greatest biologists and ethical thinkers seems to me a timely one. Modern scientific methods engender ceaseless advances and ceaseless controversies, but they ‘appear impotent to give us, as Aristotle did, a reasonable view of our own species’ place and purpose.
