> rantings of someone like Aleister Crowley

Crowley had a penchant for drama and provocation (which, hilariously, still seems effective today!), but writing off his work as "rantings" is really ignoring the scholarly work he did on Western esotericism (and he also did make a lot of progress bringing greater awareness of non-Western traditions as well), which has always been an important part of Western culture (even if commonly underplayed by mainstream academia).

Technology, science and the occult have always had an interesting relationship in the West. Pythagoras, in addition to his contributions mathematics, is famous for founding a Hermetic mystery cult. As I'm sure you know, inventing physics and calculus was basically a part of Isaac Newton's study of alchemy (which has long had a big of a mystical component pulling from the Hermetic tradition as it has a proto-chemical component), and even Jack Parsons followed in that tradition (being himself a student of Crowley).

It's completely understandable if you don't find Crowley work of interest, but plenty of people also don't find Adam Smith's work of much interest either. Dismissing the work of Western esotericism on the history of the West would be similar to dismissing Sufism on the history of the Middle East.
