Post a quote, or a couple, explain who the person(s) are/were and what you like about the quote.
I'll start:
"Turn on, tune in, drop out"
This quote is by Timothy Leary, He started the "Harvard Psilocybin Project" in the 1960's when he was a professor there. He then started introducing LSD to kids and other "hippies". He was fired from Harvard for the quote stated above. He has also written numerous books about the Psychedelic experience.
I like this quote because I'm a hardcore fan of Psychedelics. Though, I do disagree with the whole "dropping out" part.
