From the Foreward: Each chapter of this work is in truth a separate essay or article in which an author distinguished in his field treats a different aspect or manifestation of violence in human society. I doubt whether so complete a treatise in so short a compass has been previously attempted.  The reader will be left in no doubt when he reflects on what he has read that violence is, and always has been, a feature or a threat in human society- and will remain so. The reason why this must be so is made plain in the early chapters. Violent behaviour is a display of man's aggressive instinct: without that instinct, which he (and she) shares with the rest of the animal kingdom, the human species would not survive.  First published in 1987.
