“Men fear thought as they fear nothing else on earth -- more than ruin, more even than death. Thought is subversive and revolutionary, destructive and terrible, thought is merciless to privilege, established institutions, and comfortable habits; thought is anarchic and lawless, indifferent to authority, careless of the well-tried wisdom of the ages. Thought looks into the pit of hell and is not afraid ... Thought is great and swift and free, the light of the world, and the chief glory of man.”
“The universe looks more and more like a great thought rather than a great machine.”
“A belief system is nothing more than a thought you've thought over and over again.”
“He thought that in the history of the world it might even be that there was more punishment than crime but he took small comfort from it.”
“There's nothing more useless than a mind filled with someone else's thoughts.”
“There is nothing more potent than thought. Deed follows word and word follows thought. And where the thought is mighty and pure, the result is mighty and pure.”
