Epicurus

Epicurus (341 BCE – 270 BCE) was an ancient Greek philosopher, the founder of the Epicurean school in Athens, who taught that "Pleasure is the principle and end to a happy life." He was a prolific writer, amassing 37 volumes, but unfortunately, only fragments and four letters remain. His teachings would influence many who followed such as Lucretius of Rome and his On the Nature of Things, and the Utilitarians Jeremy Bentham and J.S. Mill.
