Hume

Scottish philosopher and historian whose skeptical arguments concerning induction, causation and religion, including the thesis that human knowledge arises only from sense experience, shaped 19th- and 20th-century empiricist philosophy. His works include A Treatise of Human Nature (1739-1740) and History of England (1754-1762).

Politician of Northern Ireland. Head of the Social Democratic and Labour Party since 1979, Hume shared the 1998 Nobel Peace Prize with David Trimble for working to establish peace in Northern Ireland.
