"In a set of essays that reflects his thinking on animal and human rights over the past decade, Regan sketches the philosophical positions espoused by those who want to abolish animal exploitation, reform it to minimize suffering, or maintain the status quo. He considers the moral grounds for limiting human freedom when it comes to human interactions with nonhuman animals. He puts the issue of animal rights in historical context, drawing parallels between animal rights activism and other social movements, including the anti-slavery movement in the nineteenth century and the gay-lesbian struggle today. He also outlines the challenges to animal rights posed by deep ecology and ecofeminism to using animals for human purposes and addresses the ethical dilemma of the animal rights advocate whose employer uses animals for research."--BOOK JACKET.
