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

“Absolute faith corrupts as absolutely as absolute power.”

“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.”

“Passionate hatreds can give meaning and purpose to an empty life. These people haunted by the purposelessness of their lives try to find a new content not only by dedicating themselves to a holy cause but also by nursing a fanatical grievance.”

“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.”

“The remarkable thing is that we really love our neighbor as ourselves: we do unto others as we do unto ourselves. We hate others when we hate ourselves. We are tolerant toward others when we tolerate ourselves. We forgive others when we forgive ourselves. We are prone to sacrifice others when we are ready to sacrifice ourselves.”
