David Hume (; born David Home; 7 May 1711 NS (26 April 1711 OS) - 25 August 1776) was a Scottish philosopher, historian, economist, and essayist, who is best known today for his highly influential system of philosophical empiricism, skepticism, and naturalism. Hume's empiricist approach to philosophy places him with John Locke, Francis Bacon and Thomas Hobbes as a British Empiricist.
Hume's writings on ethics began in the Treatise and were refined in his An Enquiry Concerning the Principles of Morals (1751). His views on ethics are that "[m]oral decisions are grounded in moral sentiment." It is not knowing that governs ethical actions, but feelings. Arguing that reason cannot be behind morality, he wrote: Morals excite passions, and produce or prevent actions. Reason itself is utterly impotent in this particular. The rules of morality, therefore, are not conclusions of our reason. Hume's sentimentalism about morality was shared by his close friend Adam Smith, and Hume and Smith were mutually influenced by the moral reflections of their older contemporary Francis Hutcheson. Peter Singer claims that Hume's argument that morals cannot have a rational basis alone "would have been enough to earn him a place in the history of ethics". Hume also put forward the is-ought problem, later called Hume's Law, denying the possibility of logically deriving what ought to be from what is. He wrote in the Treatise that in every system of morality he has read, the author begins with stating facts about the world, but then suddenly is always referring to what ought to be the case. Hume demands that a reason should be given for inferring what ought to be the case, from what is the case. This because it "seems altogether inconceivable, how this new relation can be a deduction from others". Hume's theory of ethics has been influential in modern day meta-ethical theory, helping to inspire emotivism, and ethical expressivism and non-cognitivism, as well as Allan Gibbard's general theory of moral judgment and judgments of rationality.
