There are three strands of Gassendi's philosophy which are quite notable. First, he was responsible for making atomism respectable in European intellectual circles of the 17th century. Atomism derived from Greek philosophers, was transmitted and modified by Lucretius and Epicurus. In the Epicurean form atomism was incompatible with Christianity. Gassenid made atomism respectable by modifying it so that it did not conflict with Christianity. Thus, instead of insisting on the eternity of atoms, Gassendi has God create the atoms.
Connected with his efforts to make atomism respectable was his rejection of Aristotelianism. There was, from the Renaissance on, a revolt against Aristotelian philosophy. Many of the philosophers of the 17th century were part of this revolt. Aristotle had rejected atomism, and this gives Gassendi some reason to reject Aristotle. The conection between Aristotle and the Scholastic philosophy of the Middle Ages, which still dominated the universities in Gassendi's time, provided another reason for philosophers opposed to Scholasticism to reject Aristotelian philosophy.
The third feature of Gassendi's philosophy is that he advocated a moderate skepticism. This moderate skepticism influenced philosophy perhaps more profoundly than Descartes' attempts to refute skepticism entirely.
