From Newton’s Principia to the Rights of Man

A century of people who thought that reason, evidence and argument in print could remake the world. It begins in 1687 with Newton showing that one law moves the Moon and the tides, and ends in August 1789 with a French assembly declaring that men are born free and equal in rights. Between them come the Encyclopédie, the Paris salons, Voltaire’s campaigns, the Scots, Kant’s Königsberg and Franklin’s Philadelphia.

It was never one city’s. The books were printed in Amsterdam, Rotterdam, Leiden and Geneva to get past French censors; the ideas were argued over in Edinburgh, Naples, Milan, Berlin and St Petersburg. And women did more than pour the tea: Émilie du Châtelet translated Newton, Laura Bassi taught physics at Bologna, and the salonnières ran the conversation the philosophes needed.

Two calendars

Both calendars appear here. France and most of the continent counted Gregorian dates, but Britain and its colonies kept the Julian calendar, eleven days behind, until they skipped from Wednesday 2 to Thursday 14 September 1752. So Newton, Locke, Hume and Franklin’s kite carry Julian dates, as they wrote them, and so do Catherine the Great’s: Russia kept the old calendar until 1918. The English also began the year on 25 March, which is why Newton’s tomb says he died in 1726 while the timeline puts it in 1727.

How it is laid out

  • Periods: the three great Paris salons, the Encyclopédie’s twenty-one years in print, and Voltaire’s homes, from English exile to Ferney. Events that belong to one of them are nested inside it.

  • Threads to filter by: salons, censorship, voltaire, science, women and rights.
