“Experience has shown, and a true philosophy will always show, that a vast, perhaps the larger, portion of truth arises from the seemingly irrelevant.”

“The process of secularisation arises not from the loss of faith but from the loss of social interest in the world of faith. It begins the moment men feel that religion is irrelevant to the common way of life and that society as such has nothing to do with the truths of faith.”

“Nature does not teach. A true philosophy may sometimes validate an experience of nature; an experience of nature cannot validate a philosophy. Nature will not verify any theological or metaphysical proposition (or not in the manner we are now considering); she will help to show what it means.”

“The peculiarity of the evidence of mathematical truths is, that all the argument is on one side. There are no objections, and no answers to objections. But on every subject on which difference of opinion is possible, the truth depends on a balance to be struck between two sets of confliting reasons. Even in natural philosophy, there is always some other explanation possible of the same facts; some geocentric theory instead of heliocentric, some phlogiston instead of oxygen; and it has to be shown why that other theory cannot be the true on: and until this is shown, and until we know how it is shown, we do not understand the grounds of our opinion. But when we turn to subjects infinitely more complicated, to morals, religion, politics, social relations, and the business of life, three-fourths of the arguments for every disputed opinion consist in dispelling the appearances which favour some opinion different from it.”

“But although all our knowledge begins with experience, it does not follow that it arises from experience.”

“From my experience, honey, if he seems too good to be true—he probably is.”
