My friend Massimo Pigliucci has written a fun-but-also-serious comprehensive book that updates Stoicism. Admittedly, I was skeptical of Stoicism, but this book (along with Nussbaum’s) has changed some of my views because it shows that the philosophy is not all about resignation, indifference, and having a stiff upper lip. Through the lens of the Stoic virtues – practical wisdom, courage, temperance, and justice – Pigliucci highlights how it can be applied as a force for good: not only helping people through difficult times, but also on a grander scale through social activism and criminal justice reform.
