The history of morals is the extension of the reciprocal or selfish virtues from the clan to the tribe, from the tribe to the nation, from the nation to all communities living under the same government, civil or religious, then people of the same colour, and finally to all mankind.

Defense of morals is the battle-cry which best rallies stupidity against change.

As the grand discordant harmony of the celestial bodies may be explained by the simple principles of gravity and impulse, so also in that more wonderful and complicated microcosm the heart of man, all the phenomena of morals are perhaps resolvable into one single principle, the pursuit of apparent good; for although customs universally vary, yet man in all climates and countries is essentially the same.

The Virtue of Prosperity is Temperance; the Virtue of Adversity is Fortitude: which in Morals is the more Heroical Virtue.

To speak in a mean, the virtue of prosperity is temperance, the virtue of adversity is fortitude, which in morals is the more heroic virtue.

Be good enough to remember that your morals are only your habits; and do not call other people immoral because they have other habits.

The nation's morals are like its teeth: the more decayed they are the more it hurts to touch them.

Love is but a prelude to life, an overture in which the theme of the impending work is exquisitely hinted at, but which remains nevertheless only a symbol and a promise. What is to follow, if all goes well, begins presently to appear. Passion settles down into possession, courtship into partnership, pleasure into habit. A child, half mystery and half plaything, comes to show us what we have done and to make its consequences perpetual. We see that by indulging our inclination we have woven about us a net from which we cannot escape: our choices, bearing fruit, begin to manifest our destiny. That life which once seemed to spread out infinitely before us is narrowed to one mortal career. We learn that in morals the infinite is a chimera, and that in accomplishing anything definite a man renounces everything else. He sails henceforth for one point of the compass.

It is a paradox of the acquisitive society in which we now live that although private morals are regulated by law, the entrepreneur is allowed considerable freedom to use - and abuse - the public in order to make money. The American pursuit of happiness might be less desperate if the situation were reversed.

So far as I have observed in this life, ten men have failed from defect in morals where one has failed from defect in intellect.

Never let your sense of morals keep you from doing what is right.

All luxury corrupts either the morals or the taste.

He that lends an easy and credulous ear to calumny is either a man of very ill morals or has no more sense and understanding than a child.

Beware when the great God lets loose a thinker on this planet. Then all things are at risk. The very hope of man. The thoughts of his heart, the religion of nations, the manners and morals of mankind are all at the mercy of a new generalization.

If a nation of men is exalted to that height of morals as to refuse to fight and choose rather to suffer loss of goods and loss of life than to use violence, they must be not helpless but most effective and great men; they would overawe their invader, and make him ridiculous; they would communicate the contagion of their virtue and inoculate all mankind.

To educate man in mind and not in morals is to educate a menace to society.

For avoiding the extremes of despotism or anarchy ... the only ground of hope must be on the morals of the people. I believe that religion is the only solid base of morals and that morals are the only possible support of free governments.

It is becoming clear that the old platitudes can no longer be maintained, and that if we wish to improve our morals we must first improve our knowledge.

A straight line is shortest in morals as well as in geometry.

The greatest happiness of the greatest number is the foundation of morals and legislation.
