“Absolute faith corrupts as absolutely as absolute power.”

“We can be absolutely certain only about things we do not understand.”

“It has often been said that power corrupts. But it is perhaps equally important to realize that weakness, too, corrupts. Power corrupts the few, while weakness corrupts the many. Hatred, malice, rudeness, intolerance, and suspicion are the faults of weakness. The resentment of the weak does not spring from any injustice done to them but from their sense of inadequacy and impotence. We cannot win the weak by sharing our wealth with them. They feel our generosity as oppression.”

“Faith in a holy cause is to a considerable extent a substitute for the lost faith in ourselves.”

“Even the sober desire for progress is sustained by faith—faith in the intrinsic goodness of human nature and in the omnipotence of science. It is a defiant and blasphemous faith, not unlike that held by the men who set out to build a "city and a tower, whose top may reach unto heaven" and who believed that "nothing will be restrained from them, which they have imagined to do.”

“Where there is the necessary technical skill to move mountains, there is no need for the faith that moves mountains.”

“The enemy—the indispensible devil of every mass movement—is omnipresent. He plots both outside and inside the ranks of the faithful. It is his voice that speaks through the mouth of the dissenter, and the deviationists are his stooges. If anything goes wrong within the movement, it is his doing. It is the sacred duty of the true believer to be suspicious. He must be constantly on the lookout for saboteurs, spies and traitors.”
