“Periods of mass madness”

Jihadi John

“There are periods in the life of humanity, which generally coincide with the beginning of the fall of cultures and civilizations, when the masses irretrievably lose their reason and begin to destroy everything that has been created by centuries and millenniums of culture. Such periods of mass madness…often [coincide] with geological cataclysms, climatic change, and similar phenomena….” ∼ from In Search of the Miraculous by P.D. Ouspensky (1949)
