Well, lately I've been writing more philosophical (rather than religious or political) articles because they seem more likely to get boosted. (This one on monstrousness just got boosted, for instance.)
I appreciate the summary and your longstanding interest in my writing. I do aim for a coherent worldview, although I don't know if it qualifies as a "system." If it is a system, the crucial thing would be to identify the starting point from which everything else can be inferred.
I'd say there are multiple starting points or principles, which I talk about in an article on my philosophical influences (link below). Atheism, for instance, or your point #1 follows from naturalism, and that indeed is one starting point. That's where I get my view of scientific objectification, and thus the cosmicist, horrific picture of nature that inspires the secular humanist counter-creativity (civilization). From there, I'd distinguish between countercultures and mainstream cultures, to get at my views of history, sociology, and politics.
So that's one key line of thought. Another would be epistemological, meaning my pragmatic neo-Kantianism which I take to incorporate the best of modern and postmodern views of knowledge. My epistemology underlies some of my specific criticisms of religion, for example.
So most of your summaries are more or less accurate, but they're not quite tied together in the way I'd emphasize. I think your version of my take on transhumanism isn't exactly right. The dehumanization of us wouldn't be purely tragic, but would amount to a mystical, all-embracing perspective, something akin to the countercultural vision that overcomes egoism.
I'd say my picture makes us out to be tragic heroes, not just tragic. The tragedy and horror come from the cosmicist take on naturalism, but you're leaving out my defense of secular humanism, and the nobility of civilization as an existential revolt, even if it's ultimately doomed. Whether cosmicist pantheism is consistent with humanism is perhaps questionable, making for a tension in my worldview. My articles might emphasize one or the other side, depending on my mood.
I should also say that I've been posting an exclusive summary of my philosophy for paying members on my Substack page. It's calling Cosmic Inklings and it's written in the aphoristic style of the Dhammapada. I'm still adding chapters, and eventually I might include the whole thing in a paperback anthology.
