Hume may refer to:

David Hume (7 May [O.S. 26 April] 1711 – 25 August 1776) was a Scottish philosopher, historian, economist, and essayist, known especially for his philosophical empiricism and scepticism. He was one of the most important figures in the history of Western philosophy and the Scottish Enlightenment. Hume is often grouped with John Locke, George Berkeley, and a handful of others as a British Empiricist.

Beginning with his A Treatise of Human Nature (1739), Hume strove to create a total naturalistic "science of man" that examined the psychological basis of human nature. In stark opposition to the rationalists who preceded him, most notably Descartes, he concluded that desire rather than reason governed human behaviour, saying: "Reason is, and ought only to be the slave of the passions." A prominent figure in the sceptical philosophical tradition and a strong empiricist, he argued against the existence of innate ideas, concluding instead that humans have knowledge only of things they directly experience. Thus he divides perceptions between strong and lively "impressions" or direct sensations and fainter "ideas", which are copied from impressions. He developed the position that mental behaviour is governed by "custom"; our use of induction, for example, is justified only by our idea of the "constant conjunction" of causes and effects. Without direct impressions of a metaphysical "self", he concluded that humans have no actual conception of the self, only of a bundle of sensations associated with the self.

John Passmore AC (9 September 1914 – 25 July 2004) was an Australian philosopher.

Passmore was born in Manly, Sydney. He was educated at Sydney Boys High School and subsequently graduated from the University of Sydney with first-class honours in English literature and philosophy, and went on to study to become a secondary-school teacher. In 1934 he accepted the position of assistant lecturer in philosophy at the University of Sydney, continuing teaching there until 1949. In 1948 he went to study at the University of London.

From 1950 to 1955 he was professor of philosophy at the University of Otago in New Zealand. In 1955 he spent a year at the University of Oxford on a Carnegie grant. Upon his return to Australia he took up a post at the Institute of Advanced Studies at the Australian National University, where he was professor of Philosophy in the Research School of Social Sciences from 1958 to 1979.

In 1960 he was Ziskind visiting professor at Brandeis University in the United States. He subsequently lectured in England, the United States, Mexico, Japan, and in various European countries.

Fernando Fernández-Savater Martín (born 21 June 1947) is one of Spain's most popular living philosophers, as well as an essayist and celebrated author.

Born at San Sebastián, he was an Ethics professor at the University of the Basque Country for over a decade. Presently he is a Philosophy professor at the Complutense University of Madrid. He has won several accolades for his literary work, which covers issues as diverse as contemporary ethics, politics, cinema and literary studies. In 1990, Savater and columnist and publisher, Javier Pradera, founded the magazine, Claves de Razón Práctica.

He has taken an active part in several organizations engaged with peace in the Basque Country and against terrorism and Basque nationalism, such as Movimiento por la Paz y la No Violencia, Gesto por la Paz, Foro Ermua, and currently ¡Basta Ya!.

He defines himself as an agnostic, an anglophile and a defender of the Enlightenment in the Voltaire tradition.

He recently founded a new political party called Unión, progreso y democracia (Union, Progress and Democracy) with former socialist MP Rosa Díez in order to oppose different nationalist movements in Spanish mainstream politics. Critics have pointed out that their political outlook seems to be dominated by a strong Spanish nationalist ideology itself.
