What is the difference between Stoicism and Epicurean Philosophy?
Listen to the latest Lucretius Today Podcast! Episode 226 is now available. We begin (with the help of Cicero's Epicurean spokesman) the first of a series of episodes to analyze the Epicurean view of the nature of the gods.
Short Answer: The differences between Stoicism and Epicurean philosophy are deep and profound. Modern advocates of variations of Stoicism tend to blur the differences, but the ancient authorities who knew both systems well considered them to be totally incompatible, especially in terms of the goal of life and the role of reason in the determination of truth.
