Cover for the book, Animal Liberation.

Animal Liberation

Author: Peter Singer · Subject: Animal Rights


In his introduction, Peter Singer writes: “This book is about the tyranny of human over non-human animals. This tyranny has caused and today is still causing an amount of pain and suffering that can only be compared with that which resulted from centuries of tyranny by white humans over black humans.”

Since its original publication in 1975, this groundbreaking work has awakened millions of concerned men and women to the shocking abuse of animals everywhere — inspiring a worldwide movement to eliminate much of the cruel and unnecessary laboratory animal experimentation of years past.

An important and persuasive appeal to conscience, fairness, decency, and justice, Animal Liberation is essential reading for the supporter and the skeptic alike.
