This collection of essays focuses on the connection between biology and questions in ethics.

Although science may claim to be "objective," scientists cannot avoid the influence of their own values on their research. In The State of Nature, Gregg Mitman examines the relationship between issues in early twentieth-century American society and the sciences of evolution and ecology to reveal how explicit social and political concerns influenced the scientific agenda of biologists at the University of Chicago and throughout the United States during the first half of this century. Reacting against the view of nature "red in tooth and claw," ecologists and behavioral biologists such as Warder Clyde Allee, Alfred Emerson, and their colleagues developed research programs they hoped would validate and promote an image of human society as essentially cooperative rather than competitive. Mitman argues that Allee's religious training and pacifist convictions shaped his pioneering studies of animal communities in a way that could be generalized to denounce the view that war is in our genes.

Fifty-six items, plus documentary 'supplements', can be considered a biographical as well as theoretical working edition of the origins and development of Korzybski's revolutionary system called "general semantics".

Biographic Memoirs: Volume 53 contains the biographies of deceased members of the National Academy of Sciences and bibliographies of their published works.

Much recent thought on the ethics of new biomedical technologies, and work in ethics and political philosophy more generally, is committed to hidden and contestable views about the nature of biological reality. This selection of essays by Tim Lewens, a leading expert in the field, teases out these biological foundations of bioethical writing and subjects them to scrutiny. The topics covered include human enhancement, the risks of technical progress, the alleged moral threat of synthetic biology, the reality of human nature, the relevance of evolutionary psychology to social policy, the nature of the distinction between health and disease, and justice in healthcare decision-making.

Explores the extent to which Aristotle's ethical treatises employ the concepts, methods, and practices developed in his 'scientific' works.
