The book is designed to bring together under one cover a wide variety of philosophers belonging to the Western world from Thales (620–546 B.C.) to Jürgen Habermas and Hilary Putnam, who are still living today. It is prepared in such a way that its contents are sufficiently clear and brief to be understandable to an average student of philosophy, more especially if he/she is a beginner. It is specially devised to be used as a simple reference guide for the students of philosophy.
Besides more than 90 philosophers, the book contains about 150 key frequently used philosophical terms and concepts; over 250 French, German, Greek and Latin words commonly used in philosophy with their meaning in English; about 100 philosophical questions for reflection; and a section containing the origin, meaning, branches and methods of philosophy, along with some recent philosophical trends. The author is currently the dean of philosophy at Kristu Jyoti College, Bangalore.
