Philosopher of science Philp Kitcher presents this timely and interesting exploration of the role of science in democracy. Addressing the propensity of democratic societies to debate all issues as if factual truth could be arrived at by a vote or debate, the work examines the role of the expert and the ways in which modern political discourse hampers clear applications of scientific works for the public good. The work addresses such topics as the erosion of scientific authority, the evolution of public knowledge and accommodating diversity and dissent. Kitcher is the author of twelve books on the philosophy of science. Annotation ©2011 Book News, Inc., Portland, OR (booknews.com)
