Peter Singer (Animal Liberation Now, The Life You Can Save) is a philosopher, professor, and author. Peter joins the Armchair Expert to discuss what the concept of moral relativism is, how philosophy relates to rationality, and what the difference is between being a consequentialist versus a utilitarian. Peter and Dax talk about why ethically raising animals for food is uncommon, whether animals actually feel suffering, and what harm is done to the environment by raising animals on a commercial level. Peter explains why he started doing studies on effective altruism, how people can know if their charitable donations are actually helping people, and why he is drawn to asking questions about controversial ideas.
