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.

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. This book emphasizes the broad range of Strauss's influence, from literary criticism to constitutional thought, and it denies the existence of a monolithic Straussian political orthodoxy. Both critics and supporters of Strauss' thought are included. All political theorists interested in Strauss's extraordinary impact on political thought will want to read this book.

This is a reprint of Larry Arnhart's essay "Darwinian Conservatism" with comment and criticism from a variety of contributors.

The Left has traditionally assumed that human nature is so malleable, so perfectible, that it can be shaped in almost any direction. Conservatives object, arguing that social order arises not from rational planning but from the spontaneous order of instincts and habits. Darwinian biology sustains conservative social thought by showing how the human capacity for spontaneous order arises from social instincts and a moral sense shaped by natural selection in human evolutionary history.
