What I know at sixty, I knew as well at twenty. Forty years of a long, a superfluous, labor of verification.

The discovery that mass changes with velocity, a discovery made when minute bodies came under consideration, finally forced surrender of the notion that mass is a fixed and inalienable possession of ultimate elements or individuals, so that time is now considered to be their fourth dimension.

Several particular maxims... are as powerful, although false, in carrying away belief, as those the most true.

Sleep is a death; oh, make me try By sleeping what it is to die, And as gently lay my head On my grave as now my bed.

Fiction is to the grown man what play is to the child; it is there that he changes the atmosphere and tenor of his life.

The conscious mind allows itself to be trained like a parrot, but the unconscious does not - which is why St. Augustine thanked God for not making him responsible for his dreams.

And the conversion of the other Don Quixote - he who was converted only to die - was possible because he was mad, and it was his madness, and not his death or his conversion that immortalized him, earning him forgiveness for this crime of having been born. Felix culpa! And neither was his madness cured, but only transformed. His death was his last knightly adventure; in dying he stormed heaven, which suffereth violence.

For thus it is, men of Athens, in truth: wherever a man has placed himself thinking it is the best place for him, or has been placed by a commander, there in my opinion he ought to stay and to abide the hazard, taking nothing into the reckoning, either death or anything else, before the baseness of deserting his post.

It may be observed, that provinces amid the vicissitudes to which they are subject, pass from order into confusion, and afterward recur to a state of order again; for the nature of mundane affairs not allowing them to continue in an even course, when they have arrived at their greatest perfection, they soon begin to decline. In the same manner, having been reduced by disorder, and sunk to their utmost state of depression, unable to descend lower, they, of necessity, reascend; and thus from good they gradually decline to evil, and from evil again return to good. The reason is, that valor produces peace; peace, repose; repose, disorder; disorder, ruin; so from disorder order springs; from order virtue, and from this, glory and good fortune.

A conception of justice cannot be deduced from self evident premises or conditions on principles; instead, its justification is a matter of the mutual support of many considerations, of everything fitted together into one coherent view.

During the last three centuries, there has been, by virtue of the Inquisition, a greater enjoyment of peace, and happiness, in Spain, than in the other nations of Europe.

Being is only Being for Dasein.

Logic has borrowed, perhaps, the rules of geometry, without comprehending their force... it does not thence follow that they have entered into the spirit of geometry, and I should be greatly averse... to placing them on a level with that science that teaches the true method of directing reason.

What is so remarkable about Crowley the 'magician' is that he remains Crowley the scientist, and always applies the same probing intellectual curiosity to every field he surveys. This is ultimately the most impressive quality about his mind, and the one that might -- if he had concentrated on developing it to the full -- have brought him the fame that he craved. Crowley's tragedy was that he never concentrated long enough to develop anything to the full.

Art is the activity that exalts and denies simultaneously. "No artist tolerates reality," says Nietzsche.

The members of Christ, many though they be, are bound to one another by the ties of charity and peace under the one Head, who is our Saviour Himself, and form one man. Often their voice is heard in the Psalms as the voice of one man; the cry of one is as the cry of all, for all are one in One.

If it were so, as conceited sagacity, proud of not being deceived, thinks, that we should believe nothing that we cannot see with our physical eyes, then we first and foremost ought to give up believing in love. ... We can be deceived by believing what is untrue, but we certainly are also deceived by not believing what is true. ... Which deception is more dangerous?

Heroes abound at the dawn of civilizations, during pre-Homeric and Gothic epochs, when people, not having yet experienced spiritual torture, satisfy their thirst for renunciation through a derivative: heroism.

When animus and anima meet, the animus draws his sword of power and the anima ejects her poison of illusion and seduction. The outcome need not always be negative, since the two are equally likely to fall in love (a special instance of love at first sight).

A propensity to hope and joy is real riches: One to fear and sorrow, real poverty.

All a writer has to do to get a woman is to say he's a writer. It's an aphrodisiac.

To none is life given in freehold; to all on lease.

Each visitor performed the ceremony of greeting this old aunt whom not one of them knew, not one of them wanted to know, and not one of them cared about; Anna Pávlovna observed these greetings with mournful and solemn interest and silent approval. The aunt spoke to each of them in the same words, about their health and her own, and the health of Her Majesty, "who, thank God, was better today." And each visitor, though politeness prevented his showing impatience, left the old woman with a sense of relief at having performed a vexatious duty and did not return to her the whole evening.

The true Gospel has it that we are justified by faith alone, without the deeds of the Law.

It is never to be expected in a revolution that every man is to change his opinion at the same moment. There never yet was any truth or any principle so irresistibly obvious that all men believed it at once. Time and reason must cooperate with each other to the final establishment of any principle; and therefore those who may happen to be first convinced have not a right to persecute others, on whom conviction operates more slowly. The moral principle of revolutions is to instruct, not to destroy.

Our grand business undoubtedly is, not to see what lies dimly at a distance, but to do what lies clearly at hand.

Ancient histories, as one of our wits has said, are but fables that have been agreed upon.

No wind serves him who addresses his voyage to no certain port.

I myself believe that the evidence for God lies primarily in inner personal experiences.

It is the necessary, though very slow and gradual, consequence of a certain propensity in human nature which has in view no such extensive utility; the propensity to truck, barter, and exchange one thing for another.

Affectation is a very good word when someone does not wish to confess to what he would none the less like to believe of himself.

Without being known too well, it [India] has existed for millennia in the imagination of the Europeans as a wonderland. Its fame, which it has always had with regard to its treasures, both its natural ones, and in particular, its wisdom, has lured men there.

People will become faint out of fear and expectation of the things coming upon the inhabited earth, for the powers of the heavens will be shaken. And then they will see the Son of man coming in a cloud with power and great glory.

I was sitting in a chair in the patent office at Bern when all of sudden a thought occurred to me: If a person falls freely he will not feel his own weight. I was startled. This simple thought made a deep impression on me. It impelled me toward a theory of gravitation.

The whole life of an American is passed like a game of chance, a revolutionary crisis, or a battle.

The detour to ideality leads to coinciding with oneself, that is, to certainty, which remains the guide and guarantee of the whole spiritual adventure of being.

Maybe the target nowadays is not to discover what we are but to refuse what we are.

Hayek watched the interwar collapse with horror, as Keynes did, and shared many of Keynes's liberal values. What he failed to understand is that these values cannot be renewed by applying any formula or doctrine, or by trying to construct an ideal liberal regime in which freedom is insulated from the contingencies of politics.

The Grecian are youthful and erring and fallen gods, with the vices of men, but in many important respects essentially of the divine race. In my Pantheon, Pan still reigns in his pristine glory, with his ruddy face, his flowing beard, and his shaggy body, his pipe and his crook, his nymph Echo, and his chosen daughter Iambe; for the great god Pan is not dead, as was rumored. No god ever dies. Perhaps of all the gods of New England and of ancient Greece, I am most constant at his shrine.

Every oasis is an island that has water inside it but not round it.

In youth it is the outward aspect of things that most engages us; while in age, thought or reflection is the predominating quality of the mind. Hence, youth is the time for poetry, and age is more inclined to philosophy. In practical affairs it is the same: a man shapes his resolutions in youth more by the impression that the outward world makes upon him; whereas, when he is old, it is thought that determines his actions.

From the moment when labour can no longer be converted into capital, money, or rent, into a social power capable of being monopolized, i.e., from the moment when individual property can no longer be transformed into bourgeois property, into capital, from that moment, you say individuality vanishes.

Every man I meet is in some way my superior, and in that, I can learn of him.

Besides the noble art of getting things done, there is the noble art of leaving things undone. The wisdom of life consists in the elimination of non-essentials.

But plants, though they have not powers of perception, yet, as they have life, certainly approach very nearly to those things which are endowed with sentient faculties. What then is so completely insensible as stony substance? yet even in this, there appears to be a desire of union. Thus the loadstone attracts iron to it, and holds it fast in its embrace, when so attracted. Indeed, the attraction of cohesion, as a law of love, takes place throughout all inanimate nature.

Everybody knows that the same sum of money is of much greater value to a poor man that to a rich one. Give £10 a year to the man who has but £10 a year, you double his income, and you nearly double his enjoyments. Add £10 more, you do not add to his enjoyments so much as you did by the first £10. The third £10 is less valuable than the second, and the fourth less valuable than the third. To the possessor of £1,000 a year the addition of £10 would be scarcely perceptible; to the possessor of £10,000 it would not be worth slooping for.The richer a man is the less he is benefited by any further addition to his income. The man of £4,000 a year has four times the income of the man who has but £1,000; but does anybody suppose that he has four times the happiness?

Suffer it to be so now: for thus it becometh us to fulfil all righteousness.

As a general rule, all that has been hitherto advanced respecting the nature of this deity, must be understood to refer to his properties: for the nature of the god is not one thing, and his influence another: and truly, besides these two, his energy a third thing: seeing that all things which he wills, these he is, he can, and he works. For neither doth he will that which he is not; nor is he without strength to do that which he wills; nor doth he will that which he cannot effect. Now this is very different in the case of men, for theirs is a double nature mixed up in one, that of soul and body; the former divine, the latter full of darkness and obscurity: hence naturally arise warfare and discord between the two.
