The great mystery of my lifetime has been the 1960s. It’s worth returning to this vast subject periodically as new perspectives unveil themselves.
The closest thing to a successful prophecy of that era was made by science-fiction writer Robert A. Heinlein in his 1941 Future History chart, in which he foresaw the coming “Crazy Years” when there would be a “gradual deterioration of mores, orientation and social institutions, terminating in mass psychoses….” (By the late 60s, hippies were so drug-addled that they made Heinlein’s self-indulgent 1961 book Stranger in a Strange Land into a cult novel.)
