"Young men," said Cæsar, "hear an old man to whom old men hearkened when he was young."

Because energy is not restrained by other elements that are at once antagonistic and cooperative, action proceeds by jerks and spasms. There is discontinuity.

Newton's law is nothing but the statistics of gravitation, it has no power whatever. Let us get rid of the idea of power from law altogether. Call law tabulation of facts, expression of facts, or what you will; anything rather than suppose that it either explains or compels.

The greatness of America lies not in being more enlightened than any other nation, but rather in her ability to repair her faults.

To each according to his threat advantage does not count as a principle of justice.

The first intellectual operation in which I arrived at any proficiency, was dissecting a bad argument, and finding in what part the fallacy lay: and though whatever capacity of this sort I attained was due to the fact that it was an intellectual exercise in which I was most perseveringly drilled by my father, yet it is also true that the school logic, and the mental habits acquired in studying it, were among the principal instruments of this drilling. I am persuaded that nothing, in modern education, tends so much, when properly used, to form exact thinkers, who attach a precise meaning to words and propositions, and are not imposed on by vague, loose, or ambiguous terms. The boasted influence of mathematical studies is nothing to it; for in mathematical processes, none of the real difficulties of correct ratiocination occur.

I, however, place economy among the first and most important republican virtues, and public debt as the greatest of the dangers to be feared.

I have no ideas, only obsessions. Anybody can have ideas. Ideas have never caused anybody's downfall.

In the vaunted works of Art The master stroke is Nature's part.

To give one's self earnestly to the duties due to men, and, while respecting spiritual beings, to keep aloof from them, may be called wisdom.

Does anything genuinely beautiful need supplementing? No more than justice does-or truth, or kindness, or humility. Are any of those improved by being praised? Or damaged by contempt? Is an emerald suddenly flawed if no one admires it? Or gold, or ivory, or purple? Lyres? Knives? Flowers? Bushes?

There ought to be system of manners in every nation which a well-formed mind would be disposed to relish. To make us love our country, our country ought to be lovely.

The rather more dubious side of Nietzsche's 'evolutionism' is his glorification of the warrior -- particularly when, as an exemplification of the warrior-hero, he chooses an archetypal 'spoilt brat' like Cesare Borgia. Nietzsche's own physical weakness and consequent inability to escape the atmosphere of the study leads him to take a rather unrealistic view of the man of action.

I tell you in truth: all men are Prophets or else God does not exist.

The science of pure mathematics, in its modern developments, may claim to be the most original creation of the human spirit.

Since the Devil is the adversary of Christ he should occupy a position equivalent to his and be the Son of God as well. Satan would be the first Son of God and Christ the second.

For the world, I count it not an Inn, but a Hospital, and a place, not to live, but to die in.

In politics, love is a stranger, and when it intrudes upon it nothing is being achieved except hypocrisy. All the characteristics you stress in the Negro people: their beauty, their capacity for joy, their warmth, and their humanity, are well-known characteristics of all oppressed people. They grow out of suffering and they are the proudest possession of all pariahs. Unfortunately, they have never survived the hour of liberation by even five minutes. Hatred and love belong together, and they are both destructive; you can afford them only in private and, as a people, only so long as you are not free.

I felt less alone when I didn't know you yet: I was waiting for the other. I thought only of his strength and never of my weakness. And now here you are, Orestes, it was you. I look at you and I see that we are two orphans.

Apart from autograph hunters, I get... many letters from Hindus, beseeching me to adopt some form of mysticism, from young Americans, asking me where I think the line should be drawn in petting, and from Poles, urging me to admit that while all other nationalism may be bad that of Poland is wholly noble. I get letters from engineers who cannot understand Einstein, and from parsons who think that I cannot understand Genesis, from husbands whose wives have deserted them - not (they say) that that would matter, but the wives have taken the furniture with them, and what in these circumstances should an enlightened male do? ...I get letters (concerning whose genuineness I am suspicious) trying to get me to advocate abortion, and I get letters from young mothers asking my opinion of bottle-feeding.

I have assumed throughout that the persons in the original position are rational.

The death of dogma is the birth of morality.

The gods we stand by are the gods we need and can use, the gods whose demands on us are reinforcements of our demands on ourselves and on one another. What I then propose to do is, briefly stated, to test saintliness by common sense, to use human standards to help us decide how far the religious life commends itself as an ideal kind of human activity . ... It is but the elimination of the humanly unfit, and the survival of the humanly fittest, applied to religious beliefs; and if we look at history candidly and without prejudice, we have to admit that no religion has ever in the long run established or proved itself in any other way. Religions have approved themselves; they have ministered to sundry vital needs which they found reigning. When they violated other needs too strongly, or when other faiths came which served the same needs better, the first religions were supplanted.

For a long while I have lived with the notion that I was the most normal being that ever existed. This notion gave me the taste, even the passion for being unproductive: what was the use of being prized in a world inhabited by madmen, a world mired in mania and stupidity? For whom was one to bother, and to what end? It remains to be seen if I have quite freed myself from this certitude, salvation in the absolute, ruin in the immediate.

I have always said, and always will say, that the studious perusal of the sacred volume will make better citizens, better fathers, and better husbands.

For as only one thing is necessary, and as the theme of the talk is the willing of only one thing: hence the consciousness before God of one's eternal responsibility to be an individual is that one thing necessary.

It is proof of a base and low mind for one to wish to think with the masses or majority, merely because the majority is the majority. Truth does not change because it is, or is not, believed by a majority of the people.

Fear is the antidote to boredom: the remedy must be stronger than the disease.

To desire you to read my book over and mark all the corrections you would wish me to make...would oblige me greatly: I know how much I shall be benefitted and I shall at the same time preserve the pretious right of private judgement for the sake of which our forefathers kicked out the Pope and the Pretender. I believe you to be much more infalliable than the Pope, but as I am a Protestant my conscience makes me scruple to submit to any unscriptural authority.

Just you think first, and don't bother to speak afterward, either.

Here we must make one of those inductive applications of the law of continuity which have produced such great results in all of the positive sciences. We must extend the law of insistency into the future. Plainly, the insistency of a future idea with reference to the present is a quantity affected by the minus sign; for it is the present that affects the future, if there be any effect, not the future that affects the present.

What interest, zest, or excitement can there be in achieving the right way, unless we are enabled to feel that the wrong way is also a possible and a natural way, - nay, more, a menacing and an imminent way? And what sense can there be in condemning ourselves for taking the wrong way, unless we need have done nothing of the sort, unless the right way was open to us as well? I cannot understand the willingness to act, no matter how we feel, without the belief that acts are really good and bad.

Art is a human activity having for its purpose the transmission to others of the highest and best feelings to which men have risen.

Most of the luxuries, and many of the so-called comforts of life, are not only not indispensable, but positive hindrances to the elevation of mankind.

Impenetrable in their dissimulation, cruel in their vengeance, tenacious in their purposes, unscrupulous as to their methods, animated by profound and hidden hatred for the tyranny of man - it is as though there exists among them an ever-present conspiracy toward domination, a sort of alliance like that subsisting among the priests of every country.

What! the inventors of ancient civilisations, the first makers of tools and tape lines, the first builders of vehicles, ships, and houses, the first observers of the laws of the heavens and the multiplication tables is it contended that they were entirely different from the inventors and observers of our own time, and superior to them? And that the first slow steps forward were of a value which has not been equalled by the discoveries we have made with all our travels and circumnavigations of the earth?

It is not for you to know the times or the seasons, which the Father hath put in his own power. But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.

We have seen that language is something precious because it allows us to express ourselves; but it is fatal when one allows oneself to be completely led astray by it, because then it prevents one from expressing oneself. Language is the source of the prejudices and haste which Descartes thought of as the sources of error.

Out of the crooked timber of humanity, no straight thing was ever made.

When he was wounded with an arrow in the ankle, and many ran to him that were wont to call him a god, he said smiling, "That is blood, as you see, and not, as Homer saith, 'such humour as distils from blessed gods.'"

If a man knows what it is right to do, he does not require a formal reason. And a person that has been thus trained, either possesses these first principles already, or can easily acquire them.

Nature consists of the elements given by the senses. Primitive man first takes out of them certain complexes of these elements that present themselves with a certain stability and are most important to him. The first and oldest words are names for "things". ... The sensations are no "symbols of things". On the contrary the "thing" is a mental symbol for a sensation-complex of relative stability. Not the things, the bodies, but colours, sounds, pressures, times (what we usually call sensations) are the true elements of the world.

The best way to drive out the devil, if he will not yield to texts of Scripture, is to jeer and flout him, for he cannot bear scorn. 

Treasury notes of small as well as high denomination, bottomed on a tax which would redeem them in ten years, would place at our disposal the whole circulating medium of the United States... The public... ought never more to permit its being filched from them by private speculators and disorganizers of the circulation.

The New Testament is an invaluable book, though I confess to having been slightly prejudiced against it in my very early days by the church and the Sabbath school, so that it seemed, before I read it, to be the yellowest book in the catalogue. Yet I early escaped from their meshes. It was hard to get the commentaries out of one's head and taste its true flavor. - I think that Pilgrim's Progress is the best sermon which has been preached from this text; almost all other sermons that I have heard, or heard of, have been but poor imitations of this. - It would be a poor story to be prejudiced against the Life of Christ because the book has been edited by Christians.

All the higher, more penetrating ideals are revolutionary. They present themselves far less in the guise of effects of past experience than in that of probable causes of future experience.

Grave talk and grave humor with the doers of the craft. Building, walling, is an operation that beyond most other manual ones requires incessant consideration - even new invention. I have heard good judges say that he excelled in it all persons they had seen.
