This ambitious book has two inter-related objectives, proposing a new theory of human behaviour and then analyzing terrorism in the light of this general theory.It starts with a new theoretical construct regarding individual motivations. Dipak Gupta posits that in order to understand human motivation, along with self-interest, we must take into account our other primordial instinct: to belong to a group. On the basis of this expanded view of human motivations, the book provides an understanding of the lifecycle of terrorist organizations. Since the lifecycle of a group is inextricably intertwined with public policies, the author also examines the role of the authorities in promoting, maintaining, and suppressing violent dissent. This innovative and broad-ranging new book will be essential reading for advanced students of terrorism studies and political science, and of great interest to students of social psychology and sociology.
