He's know as the LSD madman who encouraged people to turn on, tune in and drop out.
What he actually was was a professor at Harvard University who developed unconventional views on American society and human potential.
He attended West Point for a few years, but was bounced out for failing to rat out fellow students. His next attempt at an undergraduate eduction didn't end well either. He was expelled for spending the night in a girl's dorm room (times have changed.)
He wrote many books and ran for Governor of California and he makes a lot of sense in this interview.
