Very interesting. Written by somebody who knew the Unabomber, but of course did not suspect the truth. Kaczynski was a gifted Mathematics professor, and something about that angle kind of fascinates me. I'm not saying there is any connection between math and Kaczynski's worldview, but unlike some academic studies which can be bent to fit crazy beliefs, math is a very rigid disciplene. I don't know what it means, but its like the math part of his brain was sane, and then the social part of his brain was crazy... to me, that's crazier than just being completely crazy!
