1. Introduction
The ‘Introduction’ outlines the philosophy of Epicureanism and its founder, Epicurus (341–270 bce), and considers why it was so divisive and controversial. It explains how Epicureanism embodied a comprehensive set of teachings about nature and its living inhabitants, especially human beings. Epicurean prescriptions for the conduct of life and the attitudes to take towards love, friendship, death, and politics, were presented as following from fundamental truths about the constitution of the universe. The Roman poet Lucretius presented the Epicurean philosophy of nature in his first century bce De Rerum Natura (On the Nature of Things), which had a considerable impact on science, anthropology, and moral theory when printed versions began to circulate in the 15th century.
