Peter Singer has been an influential philosopher for a number of decades. He was a significant early voice in animal rights, has been a leading thinker of utilitarianism, and helped inspire the effective altruism movement. In this podcast episode, we try our best to talk about all of those things -- working from metaethical questions of consequentialism vs. other approaches, to specific flavors of utilitarianism, the practical demands that ethics places on people, the rights of animals, and the decisions we make at the end of our lives.
