The Fundamentals of Stoicism | How a Stoic Knows the Difference Between Good and Bad with William Mulligan

In this episode, William dives deep into one of the most fundamental—and misunderstood—principles of Stoicism: what is truly good and what is bad? William unpacks the Stoic understanding of virtue and vice, the divine principle of logos, and how testing your impressions is the cornerstone of living a good life.Through metaphors like the song of the universe, real-world examples, and Stoic insights from Epictetus, Marcus Aurelius, and Zeno, William shows how to align with nature by choosing reason, courage, justice, wisdom, and temperance. He explains why virtue is the only true good, why vice is the only bad, and how everyday challenges—from injuries and fines to dropped wallets—offer opportunities to practice Stoic values.
