Moral imperative in the context of Moral dilemmas

Peter Albert David Singer (born 6 July 1946) is an Australian moral philosopher who is Emeritus Ira W. DeCamp Professor of Bioethics at Princeton University. Singer's work specialises in applied ethics, approaching the subject from a secular, utilitarian perspective. He wrote the book Animal Liberation (1975), in which he argues for vegetarianism, and the essay "Famine, Affluence, and Morality", which argues the moral imperative of donating to help the poor around the world. For most of his career, he was a preference utilitarian. He revealed in The Point of View of the Universe (2014), coauthored with Katarzyna de Lazari-Radek, that he had become a hedonistic utilitarian.

On two occasions, Singer served as chair of the philosophy department at Monash University, where he founded its Centre for Human Bioethics. In 1996, he stood unsuccessfully as a Greens candidate for the Australian Senate. In 2004, Singer was recognised as the Australian Humanist of the Year by the Council of Australian Humanist Societies. In 2005, The Sydney Morning Herald placed him among Australia's ten most influential public intellectuals. Singer is a cofounder of Animals Australia and the founder of the non-profit organization The Life You Can Save.

In philosophy, an ethical dilemma, also called an ethical paradox or moral dilemma, is a situation in which two or more conflicting moral imperatives, none of which overrides the other, confront an agent. A closely related definition characterizes an ethical dilemma as a situation in which every available choice is wrong. The term is also used in a wider sense in everyday language to refer to ethical conflicts that may be resolvable, to psychologically difficult choices or to other types of difficult ethical problems.

This article concerns ethical dilemmas in the strict philosophical sense, often referred to as genuine ethical dilemmas. Various examples have been proposed but there is disagreement as to whether these constitute genuine or merely apparent ethical dilemmas. The central debate around ethical dilemmas concerns the question of whether there are any. Defenders often point to apparent examples while their opponents usually aim to show their existence contradicts very fundamental ethical principles. Ethical dilemmas come in various types. An important distinction concerns the difference between epistemic dilemmas, which give a possibly false impression to the agent of an unresolvable conflict, and actual or ontological dilemmas. There is broad agreement that there are epistemic dilemmas but the main interest in ethical dilemmas takes place on the ontological level. Traditionally, philosophers held that it is a requirement for good moral theories to be free from ethical dilemmas. But this assumption has been questioned in contemporary philosophy.
