This book draws attention to certain significant changes in the way in which power has been defined and it also examines some of the critical responses which those changes have evoked. The objective is not to try and evolve a universally acceptable and comprehensive definition of power, and of realted terms like authority and influence. The argument of the book is that, that would be an impossible project since social and political theories themselves constitute an intervention into political discourse of a society and they may implicitly or explicitly embody a political perspective.
