"We are incredibly heedless in the formation of our beliefs, but find ourselves filled with an illicit passion for them when anyone proposes to rob us of their companionship. It is not the ideas themselves that are dear to us, but our self-esteem which is threatened. We like to continue to believe what we have been accustomed to accept as true and the resentment aroused when doubt is cast upon any of our assumptions lead us to seek every manner of excuse for clinging to it. The result is that most of our so-called reasoning consists in finding arguments for going on believing as we already do."
