“A faith without some doubts is like a human body with no antobodies in it. People who blithely go through life too busy or indifferent to ask the hard questions about why they believe as they do will find themselves defenseless against either the experience of tragedy or the probing questions of a smart skeptic. A person's faith can collapse almost overnight if she failed over the years to listen patiently to her own doubts, which should only be discarded after long reflection.”

“Faith isn't absence of doubt. It's belief without proof, not without question.”

“The older I grow and the more I abandon myself to God's will, the lessI value intelligence that wants to know and will that wants to do; andas the only element of salvation I recognize faith, which can wait patiently, without asking too many questions.”

“No doubt, humans will do a lot of damage before we ultimately destroy ourselves. But life will continue without humans. New forms of intelligence will emerge long after this human experiment is over.”

“Faith is asking. Faith is believing. Faith is doubting. Faith is stepping out anyway.”

“We live in a culture that has, for centuries now, cultivated the idea that the skeptical person is always smarter than one who believes. You can almost be as stupid as a cabbage as long as you doubt.”
