Oswald Spengler also wrote stuff in "The Decline of the West", in particular about the rise of Caesar types at particular moments in the lifetime of civilizations considered as organisms that grow, flourish, and decline. On the other hand, Spengler may have been overly enthusiastic in fitting history to suit his narrative. Spengler was not well received by some, particularily those optimists who believe such things as "rain follows the plow", or whatever that goes by these days. The graph goes up and to the right; therefore, Singularity. These optimists may likewise be overly enthusiastic in fitting reality to a particular narrative.
