Moral certainty is always a sign of cultural inferiority. The more uncivilized the man, the surer he is that he knows precisely what is right and what is wrong. All human progress, even in morals, has been the work of men who have doubted the current moral values, not of men who have whooped them up and tried to enforce them. The truly civilized man is always skeptical and tolerant.

From the apparent usefulness of the social virtues, it has readily been inferred by sceptics, both ancient and modern, that all moral distinctions arise from education, and were, at first, invented, and afterwards encouraged ... in order to render men tractable, and subdue their natural ferocity and selfishness, which incapacitated them for society.

To the ashes of the dead glory comes too late.

It is impossible for a man to be freed from the habit of sin before he hates it, just as it is impossible to receive forgiveness before confessing his trespasses.

The worst sense of security is a false one. It's hard for people to wrap their heads around the idea that those in charge - federal, state and local agencies - might be cheating the system. But, all too often, that is exactly what happens.

The fate of an epoch that has eaten of the tree of knowledge is that it must...recognize that general views of life and the universe can never be the products of increasing empirical knowledge, and that the highest ideals, which move us most forcefully, are always formed only in the struggle with other ideals which are just as sacred to others as ours are to us.
