Marcus Aurelius reminds us that there is no difference between acting according to nature and according to reason. What did he mean?

According to Epictetus philosophy gets started when we are genuinely interested in why people disagree about things. Not in terms of factual matters, which empirical evidence can settle, but about values and how we should think about the world and therefore act in it.

Seneca tells Lucilius that he welcomes knowledge from all fields, not just philosophy. That's why he wrote books on natural questions, including on the nature of comets, earthquakes, thunderstorms, and the causes of the flooding of the Nile.

Seneca tells Lucilius that we need rest and relaxation, but we can exercise virtue even in our choice of how we relax and entertain ourselves. Consider how you refresh your mind, the next time you pick a movie or organize a vacation!

Seneca quotes the Pre-Socratic philosopher Heraclitus to the effect that everything changes all the time, panta rhei. It follows that it is futile to get attached to things, including our own bodies. Enjoy what you have, but consider it a temporary loan from the cosmos.

Marcus Aurelius talks about being helpful to society. And yet he was an emperor who waged war and presided over slavery. How do we reconcile his actions with his Stoicism? At least in three ways, explored in this episode.

A splendid example of Epictetus' sarcasm by way of a bit of dialogue with one of his students. In the course of which we learn about the virtue of practical wisdom, the discipline of desire, and the dichotomy of control.

Seneca nicely explains what a proto-emotion is, and we discuss how proto-emotions can then develop into fully formed healthy or unhealthy emotions. It all comes down to what cognitive judgment we apply to our initial response.

Seneca reminds us that real tranquillity comes from a relaxed mind with a clear conscience. Which is why Stoics engage in an evening meditation on the major events of the day, learning from their mistakes, and filing them away before going to sleep.

Seneca challenges the common assumption that someone is self-sufficient if he has enough money, a nice place to live, and so forth. True self-sufficiency requires serenity, which comes from inner strength, not from externals.
