Don't know Thoreau - will look him up. Tolstoy wrote a book called The Kingdom of God is Within You - given the context of his writing - a very religious world, it shows him as all the more of a free thinker of his time. Gandhi - in his biography, My Experiments with the Truth, quotes Tolstoy and says he was one of his greatest influences.

I'm partway through unabomber's manifesto - a very insightful man. I had to laugh as I fit so neatly into his typologies; i'm an oversocialised leftist. He's coming across as a man who feels very isolated/excluded from society.
