To all of these animals we owe respect for their basic inviolable rights.

A book of 30 extracts from major political philosophers from Plato to Russell, on the nature of animals and their relation to humanity. The book aims to demonstrate the major shifts in thinking about the place of animals in society which have taken place over 2500 years.

Looking at the impact on political thinking caused by the idea that animals are morally important beings, this text suggests that liberalism, despite having weaknesses, is the most appropriate ideological position for the protection of animal interests.

At the same time, he argues that humans have a greater interest in life and liberty than most species of nonhuman animals.

THE argument for animal rights, a classic since its appearance in 1983, from the moral philosophical point of view. With a new preface.

Gary L. Francione is a law professor and leading philosopher of animal rights theory. Robert Garner is a political theorist specializing in the philosophy and politics of animal protection. Francione maintains that we have no moral justification for using nonhumans and argues that because animals are property or economic commodities laws or industry practices requiring "humane" treatment will, as a general matter, fail to provide any meaningful level of protection. Garner favors a version of animal rights that focuses on eliminating animal suffering and adopts a protectionist approach, maintaining that although the traditional animal-welfare ethic is philosophically flawed, it can contribute strategically to the achievement of animal-rights ends. As they spar, Francione and Garner deconstruct the animal protection movement in the United States, the United Kingdom, Europe, and elsewhere, discussing the practices of such organizations as PETA, which joins with McDonald's and other animal users to "improve" the slaughter of animals. They also examine American and European laws and campaigns from both the rights and welfare perspectives, identifying weaknesses and strengths that give shape to future legislation and action.

Alasdair Cochrane introduces an entirely new theory of animal rights grounded in their interests as sentient beings. He then applies this theory to different and underexplored policy areas, such as genetic engineering, pet-keeping, indigenous hunting, and religious slaughter. In contrast to other proponents of animal rights, Cochrane claims that because most sentient animals are not autonomous agents, they have no intrinsic interest in liberty. As such, he argues that our obligations to animals lie in ending practices that cause their suffering and death and do not require the liberation of animals. Cochrane's "interest-based rights approach" weighs the interests of animals to determine which is sufficient to impose strict duties on humans. In so doing, Cochrane acknowledges that sentient animals have a clear and discernable right not to be made to suffer and not to be killed, but he argues that they do not have a prima facie right to liberty. Because most animals possess no interest in leading freely chosen lives, humans have no moral obligation to liberate them. Moving beyond theory to the practical aspects of applied ethics, this pragmatic volume provides much-needed perspective on the realities and responsibilities of the human-animal relationship.
