The Expanding Circle (book)

"The Expanding Circle" by Peter Singer explores the idea that moral concern has grown historically from small, close-knit groups to a broader, more inclusive ethical outlook. Singer argues that human moral reasoning is an evolving process, increasingly extending care and rights beyond immediate community, race, or species. He advocates for expanding our empathy and moral responsibilities to all sentient beings, emphasizing that our moral progress depends on extending compassion universally, such as in efforts to prevent animal suffering and promote global justice. The book highlights the importance of moral development as a continuous and expanding journey.
