Which philosopher, known for his 1651 book, fled to France for legal reasons?
Thomas Hobbes Thomas Hobbes ( ; 5 April 1588 – 4 December 1679), in some older texts Thomas Hobbes of Malmesbury, was an English philosopher who is considered one of the founders of modern political philosophy. Hobbes is best known for his 1651 book "Leviathan", which established the social contract theory that has served as the foundation for most later Western political philosophy. In addition to political philosophy, Hobbes also contributed to a diverse array of other fields, including history, jurisprudence, geometry, the physics of gases, theology, ethics, and general philosophy.
Francis of Marchia Francis of Marchia (c. 1290 - after 1344) was an Italian Franciscan theologian and philosopher. He was an ally of William of Ockham and Michael of Cesena, and opponent of Pope John XXII, in the struggles of the Franciscan Spirituals, leading to his expulsion from the order in 1329. He was commenting on the "Sentences" of Peter Lombard around 1320, but no longer closely bound to Lombard; for example he incidentally theorises on projectile motion, views now thought to be taken from Richard Rufus of Cornwall. He was nicknamed "Doctor Succinctus".
