A collection of essays by Alexander Rosenberg, the distinguished philosopher of science. The essays cover three broad areas related to Darwinian thought and naturalism: – the first deals with the solution of philosophical problems such as reductionism; – the second with the development of social theories; – and the third with the intersection of evolutionary biology with economics, political philosophy, and public policy. Specific papers deal with naturalistic epistemology, the limits of reductionism, the biological justification of ethics, the so-called 'trolley problem' in moral philosophy, the political philosophy of biological endowments, and the Human Genome Project and its implications for policy. Rosenberg's important writings on a variety of issues are here organized into a coherent philosophical framework which promises to be a significant and controversial contribution to scholarship in many areas. – Contents : Introduction. – 1.
