This book criticizes the common belief that we are entitled to exploit animals for our benefit because they are not as rational as people. After discussing the moral (in)significance of reason in general, the author proceeds to develop a clear, commonsensical conception of what "animal rights" is about and why everyday morality points toward the liberation of animals as the next logical step in Western moral progress. The book evaluates criticisms of animal rights that have appeared in recent philosophical literature and explains the consequences of animal liberation for our diet, science, and treatment of the environment. The issue of animal rights has become of increasing philosophical and popular importance over the past decade. "Morals, Reason, and Animals" is the first extensive, second-generation contribution to this debate. Focusing exclusively on the fundamental philosophical issues, Sapontzis both undermines the arguments that have been raised against animal rights and constructs a rebuttal that avoids the pitfalls encountered by earlier defenses. S. F. Sapontzis is Professor of Philosophy at California State University, Hayward.
