The Evolution of Moral Concern for Animals
The history of animal rights is marked by the gradual outward expansion of moral concern from human interests to non-human animals. Ancient philosophical, cultural, and religious traditions stressed compassion towards all living creatures.
Eastern Traditions: Ahimsa
Hinduism, Buddhism, and Jainism promote ahimsa — non-violence towards all living beings. These traditions acknowledge animals as sentient beings, not mere resources (Linzey & Clarke, 2005).
Western Philosophical Roots
Aristotle placed animals below humans in a hierarchy, and René Descartes notoriously described animals as "automata" without feelings. Yet voices like Plutarch and later Jeremy Bentham challenged this view.
"The question is not, Can they reason? nor, Can they talk? but, Can they suffer?" — Jeremy Bentham (1789)
19th Century Reforms
The Cruel Treatment of Cattle Act 1822 and the formation of the RSPCA in 1824 were early institutional attempts to regulate animal treatment. Although focused on cruelty prevention, they signaled growing moral conscience.
20th Century: Philosophical Revolution
Peter Singer's Animal Liberation (1975) introduced speciesism. Tom Regan's The Case for Animal Rights argued for inherent value. The movement gained legal and cultural momentum.
