Animals and Why They Matter examines the barriers that our philosophical traditions have erected between human beings and animals and reveals that the too-often ridiculed subject of animal rights is an issue crucially related to such problems within the human community as racism, sexism, and age discrimination. Mary Midgley's profound and clearly written narrative is a thought-provoking study of the way in which the opposition between reason and emotion has shaped our moral and political ideas and the problems it has raised. Whether considering vegetarianism, women's rights, or the "humanity" of pets, this book goes to the heart of the question of why all animals matter.
