Responding to volatile criticisms frequently leveled at Leo Strauss and those he influenced, the prominent contributors to this volume demonstrate the profound influence that Strauss and his students have exerted on American liberal democracy and contemporary political thought. By stressing the enduring vitality of classic books and by articulating the theoretical and practical flaws of relativism and historicism, the contributors argue that Strauss and the Straussians have identified fundamental crises of modernity and liberal democracy.

There has been a resurgence of Darwinian naturalism in political theory, as manifested in the recent work of political scientists such as Roger D. Masters, Robert J. McShea, and James Q. Wilson. They belong to an intellectual tradition that includes not only Charles Darwin but also Aristotle and David Hume. Although most political scientists believe Darwinian social theory has been refuted, their objections rest on three false dichotomies: facts versus values, nature versus freedom, and nature versus nurture. Rejecting these dichotomies would allow the social sciences to be linked to the natural sciences through Darwinian biology.

This book shows how Darwinian biology supports an Aristotelian view of ethics as rooted in human nature. Defending a conception of "Darwinian natural right" based on the claim that the good is the desirable, the author argues that there are at least twenty natural desires that are universal to all human societies because they are based in human biology. The satisfaction of these natural desires constitutes a universal standard for judging social practice as either fulfilling or frustrating human nature, although prudence is required in judging what is best for particular circumstances. The author studies the familial bonding of parents and children and the conjugal bonding of men and women as illustrating social behavior that conforms to Darwinian natural right. He also studies slavery and psychopathy as illustrating social behavior that contradicts Darwinian natural right. He argues as well that the natural moral sense does not require religious belief, although such belief can sometimes reinforce the dictates of nature.

The publication in 1975 of Edward O. Wilson's Sociobiology provoked a great controversy, for in that work Wilson claimed that ethics was rooted in human biology. On the first page of the book, he asserted that our deepest intuitions of right and wrong are guided by the emotional control centers of the brain, which evolved via natural selection to help the human animal exploit opportunities and avoid threats in the natural environment. In 1998, the publication of Wilson's Consilience renewed the controversy, as he continued to argue for explaining ethics through the biology of the moral sentiments.Footnotes* I am grateful to the Earhart Foundation for a research grant that supported the writing of this essay.
