Self-esteem is reliance on one's power to think. It cannot be replaced by one's power to deceive. The self-confidence of a scientist and the self-confidence of a con man are not interchangeable states, and do not come from the same psychological universe. The success of a man who deals with reality augments his self-confidence. The success of a con man augments his panic.
Ayn RandPeople don't want to think. And the deeper they get into trouble, the less they want to think. But by some sort of instinct, they feel that they ought to and it makes them feel guilty. So they'll bless and follow anyone who gives them a justification for not thinking. Anyone who makes a virtue - a highly intellectual virtue - out of what they know to be their sin, their weakness and their guilt.
