Dilemmas of Politics.

The essays which comprise this book were written during a period of almost twenty years for different publications on different occasions about different subjects. But they have been written by the same author, for whose unchanged philosophy and intellectual preoccupations they have furnished an opportunity for expression. They have been brought up to date and partly rewritten. Additions have been made primarily for the purpose of emphasizing
the common concern of all these essays in what has been described here as the dilemmas of politics.
