One of the leading ethical thinkers of the modern age, Peter Singer has repeatedly been embroiled in controversy. Protesters in Germany closed down his lectures, mistakenly thinking he was advocating Nazi views on eugenics. Conservative publisher Steve Forbes withdrew generous donations to Princeton after Singer was appointed professor of bioethics. His belief that infanticide is sometimes morally justified has appalled people from all walks of life. Peter Singer Under Fire gives a platform to his critics on many contentious issues. Leaders of the disability rights group Not Dead Yet attack Singer's views on disability and euthanasia. Economists criticize the effectiveness of his ideas for solving global poverty. Philosophers expose problems in Singer's theory of utilitarianism and ethicists refute his position on abortion. Singer's engaging "Intellectual Autobiography” explains how he came by his controversial views, while detailed replies to each critic reveal further surprising aspects of his unique outlook.
