A hallucination is a fact, not an error; what is erroneous is a judgment based upon it.
Bertrand RussellWhat makes a free thinker is not his beliefs, but the way in which he holds them. If he holds them because his elders told him they were true when he was young, or if he holds them because if he did not he would be unhappy, his thought is not free; but if he holds them because, after careful thought, he finds a balance in their favor, then his thought is free, however odd his conclusions may seem.
Bertrand RussellAdmit at least one painful truth to yourself every day. Teach yourself to feel that life would still be worth living even if you were not immeasurably superior to all your friends. Exercises of this sort, prolonged through several years, will at last enable you to admit facts without flinching, and will, in so doing, free you from the empire of fear over a very large field.
Bertrand RussellWe are faced with the paradoxical fact that education has become one of the chief obstacles to intelligence and freedom of thought.
