Cyclical history isn't false. Population boom/bust cycles exist in humans just like they do in every other animal. Humans reach the carrying capacity of their environment and then reach out via war for more resources.
Ascribing any fixed time scale to the cycle is going to be fallacious as it depends on environmental factors.
"Cyclical history" as theorized by Spengler and others during the 20th century is a whole set of bullshit. That's what my comments are explicitly about, I don't understand how people can miss this.
