Here’s an odd pairing: Timothy Leary, famous salesman, just two years before his death, interviewed in 1994 by Greg Kinnear on Later. The LSD guru and software developer discusses once sharing a cell block with Charles Manson, whom he describes as a “right-wing, Bible-spouting militarist.” He also gives partial credit to Marshall McLuhan for the famous phrase: “Tune in, turn on, drop out.” Begins at 11:45.
