John Locke was an English philosopher and physician, educated at Oxford, who spent several years in exile in the Netherlands before returning after 1688. His Essay Concerning Human Understanding argued that all ideas come from experience, and its chapter on identity located personal identity in sameness of consciousness extending back to past actions and thoughts, illustrated by the prince and the cobbler. His Two Treatises of Government defended natural rights and government by consent.

Key ideas

  • There are no innate ideas; all ideas derive from sensation and reflection.
  • A person is the same person as far as consciousness extends back to past actions and thoughts; if a prince's consciousness entered a cobbler's body, the prince would be there.
  • People have natural rights to life, liberty and property, and acquire property by mixing their labour with things.
  • Legitimate government rests on consent, and the people may resist a government that violates its trust.

Major works

  • An Essay Concerning Human Understanding (1689, dated 1690)
  • Two Treatises of Government (1689, dated 1690)
