Thanks. I agree there's more to say on it, although that goes for all the big topics I take up. There's always more to say on them.
I'll return to scientism and to the difference between these things in other articles. But I should point out that I've written a lot on the meaning of art, and I have other articles on the academic conflict between the arts and sciences, and on scientism in economics and philosophy.
I also have older writings on the relation between science, philosophy, and art, going back to my blog where I wrote for years before moving to Medium. Some links below if you're interested:
