Violence holds considerable philosophical interest, especially today, and yet this concept has not been given sufficient attention by contemporary philosophers. This is the first anthology of philosophical essays on the nature and justifiability of violence. The essays in this volume, taken from the last 100 years, explore a range of philosophical issues pertaining to violence. Three basic questions are scrutinized: 'What is violence?', 'Is violence always wrong?', and 'Can violence be justified?'. Students and Philosophers in political and moral philosophy, but also political theorists, political scientists, and political sociologists, will find this an important and valuable contribution.
