Thomas Jefferson Quote

And even should the cloud of barbarism and despotism again obscure the science and libraries of Europe, this country remains to preserve and restore light and liberty to them. In short, the flames kindled on the fourth of July, 1776, have spread over too much of the globe to be extinguished by the feeble engines of despotism; on the contrary, they will consume these engines and all who work them.

Letter to John Adams (12 September 1821).
