John Locke

Q: What are John Locke’s most famous works?

John Locke’s most famous works are An Essay Concerning Human Understanding (1689), in which he developed his theory of ideas and his account of the origins of human knowledge in experience, and Two Treatises of Government (first edition published in 1690 but substantially composed before 1683), in which he defended a theory of political authority based on natural individual rights and freedoms and the consent of the governed.

Q: What contributions did John Locke make to epistemology?

In epistemology (the philosophical theory of knowledge), John Locke argued against the existence of innate ideas (ideas present in the mind naturally or at birth) by showing how all except “trifling” human ideas may be derived from sensation or reflection (observation of the operations of the mind ) and how knowledge may be defined in terms of the perception of agreement or connections between ideas.

Q: What contributions did John Locke make to political theory?

In political theory, or political philosophy , John Locke refuted the theory of the divine right of kings and argued that all persons are endowed with natural rights to life, liberty, and property and that rulers who fail to protect those rights may be removed by the people, by force if necessary.

Q: How did John Locke influence the Enlightenment?

John Locke’s philosophy inspired and reflected Enlightenment values in its recognition of the rights and equality of individuals, its criticism of arbitrary authority (e.g., the divine right of kings ), its advocacy of religious toleration, and its general empirical and scientific temperament.

Q: How did John Locke influence the design of U.S. government?

John Locke’s political theory directly influenced the U.S. Declaration of Independence in its assertion of natural individual rights and its grounding of political authority in the consent of the governed. Locke also advocated a separation of executive, legislative, and judicial powers, a feature of the form of government established in the U.S. Constitution .
