Micromegas is an inhabitant of the star Sirius, 120,000 feet tall and accompanied by a dwarf from Saturn who is 6000 feet tall. During a grand tour of the universe they visit Earth in 1737 and, using makeshift microscopes, they detect a boating party of tiny human philosophers. Francois-Marie Arouet, better known by the pen name Voltaire, was a French Enlightenment writer, essayist, and philosopher known for his wit and his defense of civil liberties, including both freedom of religion and free trade. Voltaire was a prolific writer and produced works in almost every literary form including plays, poetry, novels, essays, historical and scientific works, more than 20,000 letters and more than 2,000 books and pamphlets. He was an outspoken supporter of social reform, despite strict censorship laws and harsh penalties for those who broke them. A satirical polemicist, he frequently made use of his works to criticize Catholic Church dogma and the French institutions of his day. Voltaire was one of several Enlightenment figures (along with Montesquieu, John Locke, Thomas Hobbes, and Jean-Jacques Rousseau) whose works and ideas influenced important thinkers of both the American and French Revolutions
