John Locke

The philosopher who gave the Enlightenment its operating system.

The basics

John Locke (1632–1704) was an English philosopher, physician, and political theorist whose ideas about government, human understanding, and natural rights became foundational to liberal democracy. His Two Treatises of Government (1689) argued that legitimate government requires the consent of the governed and that people have natural rights to life, liberty, and property. Thomas Jefferson drew on Locke directly when writing the Declaration of Independence.

Key ideas

Tabula rasa — Locke’s Essay Concerning Human Understanding (1690) argued that the mind at birth is a blank slate. All knowledge comes from experience — sensation and reflection. This was a direct attack on the doctrine of innate ideas (held by Descartes and, in different form, by Plato). For the novel, this matters because it places Locke firmly on the empiricist side of the great philosophical divide that also separates Newton (who believed in God-given mathematical truths) from Leibniz (who was more sympathetic to innate ideas but also built calculating machines).

Social contract — Government is an agreement among people, not a divine grant to kings. If a government violates the natural rights of its citizens, they have the right to overthrow it. This idea justified the Glorious Revolution of 1688 and later the American and French revolutions.

Religious tolerance — Locke’s Letter Concerning Toleration (1689) argued that the state should not enforce religious conformity. This was radical in a century defined by religious wars, though Locke’s tolerance had limits — he excluded Catholics (suspected of foreign loyalty) and atheists (who couldn’t be trusted to keep oaths).

The Carolina Constitution

In the novel (page 170), Locke is mentioned writing a constitution for the Carolina colony. This is real — Locke served as secretary to Anthony Ashley Cooper, Earl of Shaftesbury, who was one of the Lords Proprietors of Carolina. Locke helped draft the Fundamental Constitutions of Carolina (1669), a peculiar document that attempted to create a feudal aristocracy in the New World, complete with “landgraves” and “caciques.” It was largely unworkable and never fully implemented, but it shows Locke applying political theory to practical governance — a theme that resonates with the novel’s interest in how ideas become institutions.

Connections

Locke was woven into the novel’s social network. He was a Fellow of the Royal Society, a friend of Robert Boyle and Isaac Newton, a physician to Shaftesbury (he supervised a dangerous liver operation), and a political exile in Holland during the 1680s (fleeing James II’s government). He returned to England after the Glorious Revolution and spent his last years as the intellectual godfather of the Whig political tradition.

In the novel

Locke appears at the intersection of science and politics — the point where natural philosophy’s methods (observe, reason, test) get applied to questions about how societies should be organized. Daniel Waterhouse moves in Locke’s orbit, and Locke’s ideas about consent, rights, and tolerance form part of the philosophical backdrop against which the novel’s political conflicts play out.
