"They took inventory all right, but hung on to some of the worst items in stock. They only thought they had lost their egoism and fear; they only thought they humbled themselves.

“If temperamentally we are on the depressive side, we are apt to be swamped with guilt and self-loathing. We wallow in this messy bog, often getting a misshapen and painful pleasure out of it. As we morbidly pursue this melancholy activity, we may sink to such a point of despair that nothing but oblivion looks possible as a solution. Here, of course, we have lost all perspective, and therefore all genuine humility.”

“In every case, pain had been the price of admission into a new way of life. But this admission price had purchased more than we expected. It brought a measure of humility, which we soon discovered to be a healer of pain. We began to fear pain less and desire humility more than ever.”

"Even the chief architect [of a group's failed attempt at outside enterprises], standing in the ruins of his dream, could laugh at himself - and that is the very acme of humility."
