Technically, I also didn’t read the book. I bought it on
audible.com and listened to it while driving and walking the dog. You should try the spoken word if your condition is preventing you from reading books that may be featured on services like audible.
I’m not sure how this section is supposed to work, specifically if anyone is welcome to comment or if it’s just for the topic creator and guest. Whatever the case, no one has stopped me yet, and I think it could be considered a courtesy to try resolving basic points so that the professor, should he return from his forum sabbatical, could focus on deeper aspects.
Regarding the two pillars, all I should say is that
three disciplines are discussed in How to Be a Stoic, which are desire, action, and ascent. The dichotomy of control falls under desire (we should desire things within our control), and the virtue of which is courage and temperance. Perhaps you saw a more simplified or less structured version of this. It might be important to have the fuller picture in order to better appreciate the goal of Stoicism, which is essentially Eudaimonia or human flourishing. Item 5 in the OP suggests to me that this might not be clear.
Point 2 in the OP could also use some clarification. Stoics believe in living according to nature. Two distinguishing features of sapiens is that we are a social species and that we possess the capacity for reason. That is our nature, in part anyway, and it distinguishes us from other species. From this insight, accredited to Aristotle I believe, the Stoics derived the notion that human life is about the application of reason to social living. I suppose this reasoning may suggest that, for instance, living like a mindless animal (e.g. an anti-social murderous criminal) is not living according to human nature but rather the nature of a beast.
So indeed Stoics rely on their capacity of reason and their moral intuitions (to at least begin with) in order to develop virtue/character which they believe is necessary to live eudaemonicly.
As for your question, I don't find it very interesting, personally. Stoicism is a practice. What there is to teach of it is actually rather simple. The hard part is the practice. In this way, it's more like having a routine of going to the gym than it is a routine of going to a classroom. To get the best results at a gym it's best to know what you're doing, but by far it's about the practice, doing the work, being mindful of proper technique, etc.
I think a more interesting question might be whether or not Western culture and its particular value structure is fertile soil for Stoicism. We typically don't seek the good life or a meaningful life. We value money, status, fame, a good career, a big house with a white picket fence, and The American Dream (may it rest in peace).
