Do not be too moral. You may cheat yourself out of much life. So aim above morality. Be not simply good; be good for something.
Henry David Thoreau (1817-1862) American naturalist, poet and philosopher.
Let us with caution indulge the supposition that morality can be maintained without religion. Reason and experience both forbid us to expect that national morality can prevail in exclusion of religious principle.

Morality is the attitude we adopt toward people whom we personally dislike.

Moral excellence comes about as a result of habit. We become just by doing just acts, temperate by doing temperate acts, brave by doing brave acts.

Whenever you are to do a thing, though it can never be known but to yourself, ask yourself how you would act were all the world looking at you, and act accordingly.

Morality cannot be legislated, but behavior can be regulated. Judicial decrees may not change the heart, but they can restrain the heartless.

A system of morality which is based on relative emotional values is a mere illusion, a thoroughly vulgar conception which has nothing sound in it and nothing true.
Socrates (BC 469-BC 399) Greek philosopher of Athens
We have in fact, two kinds of morality, side by side: one that we preach, but do not practice, and another that we practice, but seldom preach.

The more things a man is ashamed of, the more respectable he is.
