Alasdair MacIntyre is one of the few professional philosophers whose writings span both technical analytical philosophy and those general moral or intellectual questions that laymen often suppose to be the province of philosophy but that are seldom discussed within its bounds. The unity of this book--made up both of original and previously published pieces--lies in its attempt to expose this dichotomy and to link beliefs and moral theories with philosophical criticism. The author successively criticizes Christianity, Marxism, and psychoanalysis for their failure to express the forms of thought and action that constitute our contemporary social life, and argues that a greater understanding of our complex world will require a more thorough inquiry into the philosophy of the social sciences.
