Enthusiasm begets enthusiasm, eloquence produces conviction for the moment; but it is only by truth to Nature and the everlasting institutions of mankind that those abiding influences are won that enlarge from generation to generation.

For the great majority of mankind are satisfied with appearances, as though they were realities and are often more influenced by the things that seem than by those that are.

The lust of avarice has so totally seized upon mankind that their wealth seems rather to possess them than they possess their wealth.

The highest of characters, in my estimation, is his who is as ready to pardon the moral errors of mankind as if he were every day guilty of some himself; and at the same time as cautious of committing a fault as if he never forgave one.

Self-love leads men of narrow minds to measure all mankind by their own capacity.

Boredom is a vital problem for the moralist, since at least half the sins of mankind are caused by fear of it.

The race of mankind would perish did they cease to aid each other. We cannot exist without mutual help. All therefore that need aid and have a right to ask it from their fellowmen; and no one who has the power of granting can refuse it without guilt.

There are two things to aim at in life: first, to get what you want; and, after that, to enjoy it. Only the wisest of mankind achieve the second.

The salvation of mankind lies only in making everything the concern of all.

To live, mankind must recover its essential humanness and its innate divinity; men must recover their capacity for humility, sanity and integrity; soldiers and civilians must see their hope in some other world than one completely dominated by the physical and chemical sciences.

There is no vice which mankind carries to such wild extremes as that of avarice.

The absolute demonstration of man’s mastery of fate and command of all condition - the victory of man - all men in this racial man, this elder brother of mankind in his triumph over sin, fear and death! But one thing had remained in my mind as necessary to prove to the mass of men to-day man’s absolute supremacy over death in all its forms as an attribute of his oneness with God, with Eternal Life, Perfect Love, Perfect Justice, Omniscience and Omnipotence.

Emotion has taught mankind to reason.

Mankind is a creature of space, a space race living on a planet in orbit around a star, as others are also doing. Mankind is not unique, as he fondly imagines. He is merely a part of the vast interstellar human family bred and nurtured by us through the eons of time on planets in different solar systems throughout the galaxy.

I have sometimes a queer mystical feeling as regards the attitude of people in general. Just as there are physical diseases, so there are diseases of feelings. In a little town like this I feel that on some days everyone goes about hating everyone else. Then something happens and a good feeling comes back. I think the whole of mankind must be like that.

A time will come when the science of destruction shall bend before the arts of peace; when the genius which multiplies our powers, which creates new products, which diffuses comfort and happiness among the great mass of the people, shall occupy in the general estimation of mankind that rank which reason and common sense now assign to it.

Not years but experiences age us; hence man would be the unhappiest of creatures were he a diligent pupil of experience. That each new generation and each new era starts out from the cradle is what keeps mankind eternally young.

Much has been said of the wisdom of old age. Old age is wise, I grant, for itself, but not wise for the community. It is wise in declining new enterprises, for it has not the power nor the time to execute them; wise in shrinking from difficulty, for it has not the strength to overcome it; wise in avoiding danger, for it lacks the faculty of ready and swift action, by which dangers are parried and converted into advantages. But this is not wisdom for mankind at large, by whom new enterprises must be undertaken, dangers met, and difficulties surmounted.

Out of the ashes of misanthropy benevolence rises again; we find many virtues where we had imagined all was vice, many acts of disinterested friendship where we had fancied all was calculation and fraud - and so gradually from the two extremes we pass to the proper medium; and, feeling that no human being is wholly good or wholly base, we learn that true knowledge of mankind which induces us to expect little and forgive much. The world cures alike the optimist and the misanthrope.

Strike from mankind the principle of faith, and men would have no more history than a flock of sheep.
