Animal Liberation Now

By Peter Singer • 2023
Singer's own update to his foundational text, fifty odd years later. Same core arguments, but with revised statistics, contemporary examples, new scientific evidence on animal cognition and sentience, and engagement with criticisms that emerged over the decades. It also grapples with issues the 1975 edition couldn't anticipate - industrial aquaculture, the global explosion of factory farming in Asia and South America, and - the sliver lining on the mushroom cloud - the rise of plant-based alternatives.
Why it matters
The original Animal Liberation can feel dated in places. The data is old and some of the examples are unfamiliar to younger readers. Animal Liberation Now solves that problem without diluting the philosophy. This is "the Bible" of animal welfare ethics in 2026.
Context
If you're historically minded or studying the movement's origins, read the 1975 original. If you want the strongest current case, read Animal Liberation Now. If you're serious, read both.
