This is a philosophical issue I struggle with constantly. Reason that is. On the one hand I’m convinced of Hume’s idea that reason is a slave to the passions. We are simply not rational animals. Haidt writes a lot about that in his The Righteous Mind book.
On the other hand, stoic virtue ethics makes a lot of intuitive sense to me. Further, I can see, at least in my own life, the benefits of an application of their teaching. The problem, as you have written about in your comments here a few times, is that stoic virtue ethics rely so heavily upon reason.
It’s difficult, if not impossible, to reconcile these two positions. This is why so often I feel my natural inclination towards epistemological modesty veers into outright epistemological nihilism.
Basically I have no idea what’s going on and I never will.
