Philosopher Peter Singer on Ethics in Theory and Practice

Peter Singer may be the world's best-known ethicist. He's regarded as the intellectual father of the animal liberation movement and has staked out prominent positions on euthanasia, abortion, the use of military force and economic inequality. We talked about those and other sticky moral questions, as well as Peter's brand of utilitarianism, which aims to provide a single logical framework for all ethical decision making.
