Many thanks for your good replies. Reading them makes me smarter
Taleb doesn’t say he is the originator of certain ideas. He certainly pays tribute to Bacon et al. His effort is to bring these disparate sources together and to generate a new theory from them. And despite his tone, which you mentioned before, he asserts he is modest and circumspect. (The anecdote about his mother’s valuation of him, which I hope you got to in the book, is very funny.) If he sounds as if he is speaking through a megaphone, it is because he is impassioned. I believe we ourselves are sometimes guilty of that on this forum .
Furthermore, he does talk about the application of certain aspects of his theory in other fields, such as military assessment of risks.
Rumsfeld distinguished unknown unknowns from known unknowns. Is that different from knowable unknowns? If so, please explain.
I’m very interested in the development of cities, architecture, city planning, and the like, so many thanks for the links. I live in Honolulu, one of the most expensive cities in the U.S.—and, not coincidentally, one of the cities with the highest homeless populations.
