“The unitive capacities of the spouses don't exist for nothing; they exist for motherhood and fatherhood. That is the matrix in which they develop, for children change us in a way we desperately need to be changed. They wake us up, they wet their diapers, they depend on us utterly. Willy-nilly, they knock us out of our selfish habits and force us to live sacrificially for others; they are the necessary and natural continuation of the shock to our selfishness which is initiated by matrimony itself.”

“in the modern era, many thinkers began to mistrust faith, viewing it as 'blind' and an enemy of reason. Their watchword was 'reason alone.' One of the difficulties of this stance is that reason cannot test its own reliability, any more than soapstone can test its own hardness. Any argument, accomplished by reasoning, that what reasoning accomplishes can be trusted, would be circular, because it would take for granted the very thing that it was trying to prove.Suppose I am at the window of a burning building. Although I can hear the firemen calling to me from far below, I cannot see them because of all the smoke. They are telling me to jump. Though I may have every reason to believe that they will catch me in their net, I may not trust them enough to overcome my fear, and so, hesitating, I burn to death. Obviously, my reasons are not the same as trust; faith surpasses reason. Even so they are reasons for trust; though faith surpasses reason, it is not irrational.”

“If anthropological data suggests something short of the ideal, that is not because nothing is universal, but because two universals are in conflict: universal moral knowledge and universal desire to evade it. The first one we owe to our creation. The second we owe to our fall.”

“If he makes humanity God and yet cries out against God's inhumanity, it is clear who has really been accused.”

“How conscience tells us that we ought to be fair, nobody knows. This we can say: we don't know it just from being told, we don't know it from the five senses, and we don't know it by inference from prior knowledge. We just know it. The knowledge is "underived.”

“Or perhaps the syndrome we are witnessing is preemptive capitulation: If we reduce our conscience to rubble before the bad men get here, they will have nothing to destroy.”

“In order to avoid believing in just one God we are now asked to believe in an infinite number of universes, all of them unobservable just because they are not part of ours. The principle of inference seems to be not Occam's Razor but Occam's Beard: "Multiply entities unnecessarily.”

“The problem was not that they failed to find these principles written upon their hearts, but that they could not bring themselves to attend closely to the inscription.”

“Those are just platitudes. Everyone has his own idea of "playing fair." "Does he? Try making up your own idea of what's fair--say, "giving the greatest rewards to the laziest workers"--and see how seriously people take you.”

“If all meaning were relative, then the meanings of the terms in the proposition "All meaning is relative" would be relative. Therefore the proposition "All meaning is relative" destroys itself. It is nothing but an evasion of reality. That seems a high price to pay, even for the privilege of killing people.”
