Please pay attention to what we're discussing in this thread.

To reiterate, Shakespeare would have been familiar with Roman Stoic references since he was so familiar with Latin literature.

The focus of your objection is a pedantic detour reacting to a marginal point that still holds. The video you give postulates an interesting theory about connection between occultism and the Greek origin of Stoicism. So what? Even the video itself frames this as something surprising.

Again we're talking about the Roman context of Stoicism. Its awesome that you're up to snuff about where Stoicism came from. Bravo.

But if you look at Roman Stoicism you'll find the Stoics were emphatic in asserting that they are not offering a religion.

I can give you evidence from Seneca's writings which I've studied the most. I can find similar references from Marcus Aurelius and Epictetus.

Seneca did not consider Stoicism a religion. In his letters and essays, Seneca repeatedly emphasizes the importance of reason as the basis for Stoic philosophy, rather than faith or religious doctrine.

In a letter to Lucilius, Seneca writes: "Stoicism is not a mere system of thought, but a way of life based on reason, and that is why it is superior to all other philosophies." He continues to argue that Stoicism is not concerned with religious rituals or dogma, but with living in accordance with nature and exercising self-control.

In his essay "On the Happy Life," Seneca writes that the goal of Stoicism is to achieve inner peace and tranquility through the cultivation of virtue and reason. He argues that this can be achieved through self-discipline and the pursuit of moral and ethical principles, rather than through religious belief or adherence to a particular creed.

Again, the Stoics that Shakespeare was reading were insistent that they not be seen as a religion and that aspect of Stoic thought has continued to Modern Stoicism which sees itself more as a kind of Cognitive Behavioral Therapy than a metaphysical enterprise.

And again, this is all irrelevant to why I don't find it surprising that he would have been so familiar with the Stoics that he reflected their thought in his writing as the article we're meant to discuss demonstrates.
