Animal Liberation

The book that gave the modern animal rights movement its name and its central argument, and one of Time’s 100 Best Nonfiction Books for a reason.

Why Consider This

Where Practical Ethics applies Singer’s utilitarian method across a dozen topics, Animal Liberation is that method fired at a single target with full force. Singer’s argument is simple to state and hard to dismiss: the capacity to suffer, not species membership, is what entitles a being to moral consideration, and by that standard most of what industrial farming does to animals is indefensible. He coined the term “speciesism” here to name the assumption he is attacking, that human interests automatically outweigh non-human ones.

Choose this one over Practical Ethics if you want to see Singer’s reasoning pushed to its most uncompromising conclusion on the single issue he is most identified with, rather than surveyed across many. It is also the more historically significant of the two: this book effectively founded a social movement, which is a rare thing for a philosophy book to do.

What to Expect

Less abstract and more evidentiary than Practical Ethics, with long, sometimes hard-to-read passages describing factory farming and animal experimentation in direct detail. Singer builds his case methodically before turning to the philosophical argument, so expect a slower opening than Practical Ethics but a more visceral payoff. At 324 pages it holds up well decades after publication, though later editions update the factual material.
