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 millennia of culture. Such periods of mass madness, often coinciding with geological cataclysms, climate changes, and similar phenomena of a planetary character, release a very great quantity of the matter of knowledge.
