Synopsis The book consists primarily of papers presented at a Seminar on ‘Rationality and Tribal Thought’ organized by the Department of Philosophy of North-Eastern Hill University in the year 2001. The papers deal with issues ranging from the intricacies of the concept of rationality embedded in modern Western thought to detailed consideration of tribal currents of thought, action and life and the problem of understanding that they throw up. The book fills an important gap in our efforts to come to grips with the ideas of diversity, plurality and unity.
