Thanks for reading, Steven! The piece you reference makes a helpful point about how ethics and cosmology are tightly linked in Stoicism. That reminds me of a remark that William James makes in the introduction to his series of lectures titled Pragmatism — that the most practical thing about a person is their view of the universe.
You have a good point here, too. It could be that some situations of partial control (e.g., climate change) emerge precisely because we’ve failed to live as a Stoic would counsel, making it a bit odd to use these situations as the basis of critiquing the philosophy. I’m not sure, however, that this accounts for all situations of partial control — love, for example. But your point is definitely worth keeping in mind for assessing the merits of Stoicism and its contemporary manifestations.
