"It is necessary to the happiness of man that he be mentally faithful to himself. Infidelity does not consist in believing, or in disbelieving, it consists in professing to believe what he does not believe."

"The most confused you will ever get is when you try to convince your heart and spirit of something your mind knows is a lie."

"Humanity does not suffer from the disease of wrong beliefs but humanity suffers from the contagious nature of the lack of belief. If you have no magic with you it is not because magic does not exist but it is because you do not believe in it. Even if the sun shines brightly upon your skin every day, if you do not believe in the sunlight, the sunlight for you does not exist."

"We need not take refuge in supernatural gods to explain our saints and sages and heroes and statesmen, as if to explain our disbelief that mere unaided human beings could be that good or wise."
