Abstract
Acrobat version This book In Defense of Animals ] provides a platform for the new animal liberation movement. A diverse group of people share this platform: university philosophers, a zoologist, a lawyer, militant activists who are ready to break the law to further their cause, and respected political lobbyists who are entirely at home in parliamentary offices. Their common ground is that they are all, in their very different ways, taking part in the struggle for animal liberation. This struggle is a new phenomenon. It marks an expansion of our moral horizons beyond our own species and is thus a significant stage in the development of human ethics. The aim of this introduction is to show why the movement is so significant, first by contrasting it with earlier movements against cruelty for animals, and then by setting out the distinctive ethical stance which lies behind the new movement.
