John Locke

1632–1704 · Empiricism · Early modern

John Locke, born in 1632, died in 1704, wrote the two books that still organise his reputation. An Essay Concerning Human Understanding, 1689, attacks innate ideas and asks the reader to suppose the mind white paper, furnished by sensation and reflection. The Second Treatise of Government, published the same year, grounds political power in a trust to protect life, health, liberty, and possessions, and it argues that each person has a property in their own person which nobody else has a right to.

Labour extends that property, within limits about spoilage and leaving enough. He was a physician, an adviser, and an exile in the Dutch years. He is an empiricist about ideas and a rights theorist about politics, and the two projects are linked by his distrust of authority that cannot say where a claim came from.

The English is his. A few entries in this library trim a theological clause or modernise nothing essential. He is not a behaviourist, and the blank paper is not a claim that infants have no nature.

Meaning & application
“To understand political power right, and derive it from its original, we must consider what state all men are naturally in, and that is a state of perfect freedom to order their actions, and dispose of their possessions and persons, as they think fit, within the bounds of the law of nature, without asking leave, or depending upon the will of any other man.”

Key ideas

  • White paper

    The mind begins without innate ideas, and experience, as sensation and reflection, furnishes the materials of thought.

  • The harm limit

    No one ought to harm another in life, health, liberty, or possessions, and liberty that does so is licence.

  • Property in the person

    Each person has a property in their own body and labour, from which ownership of goods is argued, with limits.

Major works

  • An Essay Concerning Human Understanding (1689)

    Book 1 attacks innate principles. Book 2 begins from the white paper.

  • Second Treatise of Government (1689)

Common misreadings
