John Locke's Second Treatise of Government (c. 1681) is perhaps the key founding liberal text. A Letter Concerning Toleration, written in 1685 (a year when a Catholic monarch came to the throne of England and Louis XVI unleashed a reign of terror against Protestants in France), is a classic defense of religious freedom. Yet many of Locke's other writings—not least the Constitutions of Carolina, which he helped draft—are almost defiantly anti-liberal in outlook.

This comprehensive collection brings together the main published works (excluding polemical attacks on other people's views) with the most important surviving evidence from among Locke's papers relating to his political philosophy. David Wootton's wide-ranging and scholarly Introduction sets the writings in the context of their time, examines Locke's developing ideas and unorthodox Christianity, and analyzes his main arguments. The result is the first fully rounded picture of Locke's political thought in his own words.
