“No doubt he is more than that, but we have no time to inquire.”

“Progress is born of doubt and inquiry. The Church never doubts, never inquires. To doubt is heresy, to inquire is to admit that you do not know—the Church does neither.”

“Assiduous and frequent questioning is indeed the first key to wisdom... for by doubting we come to inquiry; through inquiring we perceive the truth...”

“There is no such thing as education. The thing is merely a loose phrase for the passing on to others of whatever truth or virtue we happen to have ourselves. It is typical of our time that the more doubtful we are about the value of philosophy, the more certain we are about the value of education. That is to say, the more doubtful we are about whether we have any truth, the more certain we are (apparently) that we can teach it to our children.”

“Wait on the Lord" is a constant refrain in the Psalms, and it is a necessary word, for God often keeps us waiting. He is not in such a hurry as we are, and it is not his way to give more light on the future than we need for action in the present, or to guide us more than one step at a time. When in doubt, do nothing, but continue to wait on God. When action is needed, light will come.”

“I have no doubt that in reality the future will be vastly more surprising than anything I can imagine. Now my own suspicion is that the Universe is not only queerer than we suppose, but queerer than we can suppose.”
