The other day I was going over my notes while reading Donal Robertson’s Stoicism and the Art of Happiness, as well as Pierre Hadot’s (see photo) The Inner Citadel (his meditation on the Meditations), and have decided to produce a summary concept map of the three disciplines of Stoicism: Desire, Action, and Assent (see graphic below).
Hadot (and Robertson) suggest that each discipline is connected to one of the three pillars of Stoic philosophy, respectively Physics, Ethics and Logic. They are also linked to the four Stoic virtues: Courage and Temperance (regarding Stoic Acceptance), Justice (regarding Stoic Philanthropy), and Wisdom (regarding Stoic Mindfulness).
I added three quotes, from Epictetus and Marcus, which I think reflect the three disciplines, though of course several other equally apt citations could be substituted instead. In fact, if people have suggestions, please post them here.
At any rate, I hope the graphic is going to be a handy reminder of the connections among some of the most fundamental Stoic principles.
