A scholar of philosophy who has left tracks in Scotland and the US, Moseley introduces the branch of the discipline that investigates how individuals relate with others, asking such questions as their status relative to society, whether a coercive authority should impose law or rules of behavior, and what the basis of justice should be. He surveys various approaches, including, conservatism, socialism, anarchism, and environmentalism. Annotation ©2008 Book News, Inc., Portland, OR (booknews.com)
