Carl Edward Sagan ( November 9, 1934 – December 20, 1996 ). His last interview.
"One of the saddest lessons of history is this: If we've been bamboozled long enough we tend to reject any evidence of the bamboozle. We're no longer interested in finding out the truth. The bamboozle has captured us. It is simply too painful to acknowledge, even to ourselves, that we've been taken. Once you give a charlatan power over you, you almost never get it back." Carl Sagan
