First published in 1953, this seminal introduction to political philosophy is intended for both the student of political theory and for the general reader. After an introduction which explains the nature and purpose of philosophy, Dr Murray provides a critical examination of the principle theories advanced by political philosophers from Plato to Marx, paying special attention to contemporary issues.

The book also makes an attempt to define the essential issues of philosophical significance in contemporary politics, with special reference to the conflict between political authority and individual rights, and to show how the different moral assumptions underlying authoritarian and democratic systems of government are ultimately based upon different theories of logic.
