Tim Leary - Think for Yourself, Question Authority
I found this thesis on the internet about one of the (in)famous leaders of the 60's counterculture, Timothy Leary.
Essentially, the thesis discusses Leary's ideas of consciousness and how to obtain inner enlightenment through the use of psychidelics, such as LSD. He believed that Western peoples have been 'turned off' to seeing the world as it really is. Borrowing from the ideas of Eastern religion and enlightenment through meditation, Leary proposed a model of human consciousness. It consisted of seven levels, each one explaining a human who is progressively more in-tune with the universe and himself.
Later, he expanded on his theories to allow science and technology a place in human evolution. He believed that humans have eight 'brains', four being currently used and four that are latent in most. In the final brain, he believed that humans would communicate on the conscious level and instantaneously transmit their needs from themselves to the rest of consciousness and, in that way, politics will reform to center around the needs of individual and not of the majority.
Most of his thinking is radical and probably a product of the hallucigenic and psychidelic drugs he was taking, but buried within it are some appealing concepts. I do not endorse the use of drugs, and would advise against them, but rather I endorse the reading of this paper. It is much too interesting to not share.
It is long. I would suggest skimming through it and picking out the parts that interest you.
Edit: Bah, won't let me post it all.
