Throughout the centuries everyone from kings and presidents to Silicone Valley entrepreneurs have drawn inspiration and wisdom from Stoicism. The best way to learn about Stoic philosophy is always to go back to the foundation--the original texts, written by the great Stoic philosophers.   Three writers form the bedrock of Stoic thought: Marcus Aurelius, a Roman Emperor; Seneca, a playwright and advisor; and Epictetus, a former slave turned philosopher and teacher.  Stoic Foundations combines the work of these three pillars of Stoic thought into one essential volume, including Marcus Aurelius's Meditations, selections from Seneca's Letters from a Stoic, and Epictetus's Enchiridion.   Though they were written millennia ago, these texts have resonated with readers across the centuries, offering powerful, clear guidance that remains relevant and transformative in the modern day. Featuring an insightful introduction from Massimo Pigliucci, author of How to Be A Stoic, Stoic Foundations is essential reading for anyone interested in exploring modern Stoicism and in reading the luminaries of Stoic philosophy in their own words.
