John Carre

“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.”
― Bertrand Russell, Why Men Fight

“Men are from Earth, women are from Earth. Deal with it.”
― George Carlin

“There are only a few people out there who can completely overcome their fears, and they all live in Tibet.”
― Susan Cain, Quiet: The Power of Introverts in a World That Can't Stop Talking

“The scientists of today think deeply instead of clearly. One must be sane to think clearly, but one can think deeply and be quite insane.”
― Nikola Tesla
