Frequently asked questions

John Locke (1632-1704) was an English philosopher who laid the foundations of modern empiricism and political liberalism. What you need to remember is that he theorized natural rights — life, liberty, and property — and the right to resist tyrannical power. His ideas directly inspired the American Declaration of Independence of 1776 and the French Enlightenment. To understand this, you need to remember that he was writing in the context of the Glorious Revolution in England (1688), which established a constitutional monarchy.

Works & Achievements

An Essay Concerning Human Understanding (1690)

A major philosophical work that founds modern empiricism by asserting that all knowledge comes from sensory experience. It breaks with Cartesian rationalism and would influence the entire Enlightenment century.

Two Treatises of Government (1689)

A foundational text of political liberalism, in which Locke theorizes the social contract, natural rights (life, liberty, property) and the right of the people to resist tyranny. This text directly inspired the American Declaration of Independence of 1776.

A Letter Concerning Toleration (1689)

A plea for the separation of Church and State and for freedom of religious conscience. This courageous text, published under the cover of anonymity, is one of the first great modern texts on toleration.

Some Thoughts Concerning Education (1693)

A pedagogical treatise derived from letters to a friend, in which Locke advocates an education founded on experience, reason, and virtue rather than memorization. It profoundly influenced Rousseau and the educators of the Enlightenment.

The Reasonableness of Christianity (1695)

Locke proposes a rational and tolerant reading of the Christian faith, seeking to reconcile reason and religion, which earned him accusations of heresy from conservative theologians.

Anecdotes

During the Glorious Revolution of 1688, John Locke returned to England aboard the same ship as the future Queen Mary II. He had spent five years in exile in the Netherlands for allegedly plotting, according to King Charles II, against the monarchy. This triumphant return marked the beginning of his most productive period.

Locke was trained as a physician and saved the life of his patron Anthony Ashley Cooper, the Earl of Shaftesbury, by supervising a risky operation to drain a liver cyst. This surgical procedure, considered daring for the time, cemented their friendship and gave Locke access to the most influential political circles in England.

Although he is famous today for his political theories, Locke published his two major works — the Two Treatises of Government and An Essay Concerning Human Understanding — in the same year, 1689–1690, when he was already 57 years old. He had been working on these texts in secret for many years.

Locke was one of the founding shareholders of the Royal African Company, which was involved in the slave trade, and in 1669 drafted the Fundamental Constitutions of Carolina, which recognised slavery. This troubling contradiction between his theories on liberty and his actions is today at the heart of many historical debates.

The great and chief end, therefore, of men's uniting into commonwealths, and putting themselves under government, is the preservation of their property.
A Letter Concerning Toleration (1689)
I esteem toleration to be the chief characteristical mark of the true church, insomuch that whosoever claims to belong to it, yet persecutes and torments other men under pretence of religion, does thereby in effect depart from the true religion.
An Essay Concerning Human Understanding, Book II, Chapter 1 (1690)
Let us then suppose the mind to be, as we say, white paper, void of all characters, without any ideas: how comes it to be furnished? [...] Whence has it all the materials of reason and knowledge? [...] To this I answer, in one word, from experience.
Some Thoughts Concerning Education, §1 (1693)
I think I may say, that of all the men we meet with, nine parts of ten are what they are, good or evil, useful or not, by their education.
