Nature has pointed out a mixed kind of life as most suitable to the human race, and secretly admonished them to allow none of these biases to draw too much, so as to incapacitate them for other occupations and entertainments. Indulge your passion for science, says she, but let your science be human, and such as may have a direct reference to action and society. Abstruse thought and profound researches I prohibit, and will severely punish, by the pensive melancholy which they introduce, by the endless uncertainty in which they involve you, and by the cold reception which your pretended discoveries shall meet with, when communicated. Be a philosopher; but, amidst all your philosophy, be still a man.

Riemann has shewn that as there are different kinds of lines and surfaces, so there are different kinds of space of three dimensions; and that we can only find out by experience to which of these kinds the space in which we live belongs. In particular, the axioms of plane geometry are true within the limits of experiment on the surface of a sheet of paper, and yet we know that the sheet is really covered with a number of small ridges and furrows, upon which (the total curvature not being zero) these axioms are not true. Similarly, he says although the axioms of solid geometry are true within the limits of experiment for finite portions of our space, yet we have no reason to conclude that they are true for very small portions; and if any help can be got thereby for the explanation of physical phenomena, we may have reason to conclude that they are not true for very small portions of space.

I think no virtue goes with size; The reason of all cowardice Is, that men are overgrown, And, to be valiant, must come down To the titmouse dimension.

The fine arts once divorcing themselves from truth are quite certain to fall mad, if they do not die.

The God who gave us life, gave us liberty at the same time; the hand of force may destroy, but cannot disjoin them.

But petitional prayer is only one department of prayer; and if we take the word in the wider sense as meaning every kind of inward communion or conversation with the power recognized as divine, we can easily see that scientific criticism leaves it untouched. Prayer in this wide sense is the very soul and essence of religion.

It is the safest to be moderately base - to be flexible in shame, and to be always ready for what is generous, good, and just, when anything is to be gained by virtue.

Where without any change in circumstances the things held to be just by law are seen not to correspond with the concept of justice in actual practice, such laws are not really just; but wherever the laws have ceased to be advantageous because of a change in circumstances, in that case the laws were for that time just when they were advantageous for the mutual dealings of the citizens, and subsequently ceased to be just when they were no longer advantageous.

The characteristic of the hour is that the commonplace mind, knowing itself to be commonplace, has the assurance to proclaim the rights of the commonplace and to impose them wherever it will. As they say in the United States: "to be different is to be indecent." The mass crushes beneath it everything that is different, everything that is excellent, individual, qualified and select. Anybody who is not like everybody, who does not think like everybody, runs the risk of being eliminated. And it is clear, of course, that this "everybody" is not "everybody." "Everybody" was normally the complex unity of the mass and the divergent, specialised minorities. Nowadays, "everybody" is the mass alone.

We must live, you used to say, as if we were never going to die. - Didn't you know that's how everyone lives, including those obsessed with Death?

To believe in God is to long for His existence and, further, it is to act as if he existed; it is to live by this longing and to make it the inner spring of our action. This longing or hunger for divinity begets hope, hope begets faith, and faith and hope beget charity. Of this divine longing is born our sense of beauty, of finality, of goodness.

Let us not underrate the value of a fact; it will one day flower in a truth.

Thee might observe incidentally that if the state paid for child-bearing it might and ought to require a medical certificate that the parents were such as to give a reasonable result of a healthy child - this would afford a very good inducement to some sort of care for the race, and gradually as public opinion became educated by the law, it might react on the law and make that more stringent, until one got to some state of things in which there would be a little genuine care for the race, instead of the present haphazard higgledy-piggledy ways.

Men of learning are those who have read the contents of books. Thinkers, geniuses, and those who have enlightened the world and furthered the race of men, are those who have made direct use of the book of the world.

It is no coincidence that the ABM Treaty was signed midway between the delinking of the U.S. dollar from the gold standard in 1971 and the first oil crisis in 1973. These were the years not only of monetary and economic crises but also of both the beginning of the destruction of the welfare state and the shift of the hegemony of economic production from the factory to more social and immaterial sectors. One might think of these various transformations as different faces of one common phenomenon, one grand social transformation.

I'm not a Baptist in any formal way. I go to the Baptist church, where my wife plays the piano, on days of bad weather. On days of good weather, I ramble off into the woods somewhere. I am a person who takes the Gospel seriously, but I have had trouble conforming my thoughts to a denomination.

Announced by all the trumpets of the sky Arrives the snow, and, driving o'er the fields, Seems nowhere to alight: the whited air Hides hills and woods, the river and the heaven, And veils the farm-house at the garden's end.

To stand on one leg and prove God's existence is a very different thing from going on one's knees and thanking Him.

This great maxim of philosophy he had gathered by the teaching of nature alone - that man was created to work, not to speculate or feel or dream. Accordingly, he set his whole heart thitherwards. He did work wisely and unweariedly, and perhaps performed more with the tools he had than any man I now know.

To love truth for truth's sake is the principal part of human perfection in this world, and the seed-plot of all other virtues.

When I play with my cat, who knows if I am not a pastime to her more than she is to me?

The natural way of doing this [seeking scientific knowledge or explanation of fact] is to start from the things which are more knowable and obvious to us and proceed towards those which are clearer and more knowable by nature; for the same things are not 'knowable relatively to us' and 'knowable' without qualification. So in the present inquiry we must follow this method and advance from what is more obscure by nature, but clearer to us, towards what is more clear and more knowable by nature. Now what is to us plain and obvious at first is rather confused masses, the elements and principles of which became known to us by later analysis...

To spendthrifts money is so living and actual-it is such a thin veil between them and their pleasures! There is only one limit to their fortune-that of time; and a spendthrift with only a few crowns is the Emperor of Rome until they are spent. For such a person to lose his money is to suffer the most shocking reverse, and fall from heaven to hell, from all to nothing, in a breath.

The way of the superior man may be found, in its simple elements, in the intercourse of common men and women; but in its utmost reaches, it shines brightly through Heaven and Earth.

New technological environments are commonly cast in the molds of the preceding technology out of the sheer unawareness of their designers.

Time will prolong time, and life will serve life. In this field that is both limited and bulging with possibilities, everything to himself, except his lucidity, seems unforeseeable to him. What rule, then, could emanate from that unreasonable order? The only truth that might seem instructive to him is not formal: it comes to life and unfolds in men. The absurd mind cannot so much expect ethical rules at the end of its reasoning as, rather, illustrations and the breath of human lives.

There is a kind of latent omniscience not only in every man but in every particle.

They sang the praises of nature, of the sea, of the woods. They liked making songs about one another, and praised each other like children; they were the simplest songs, but they sprang from their hearts and went to one's heart. And not only in their songs but in all their lives they seemed to do nothing but admire one another. It was like being in love with each other, but an all-embracing, universal feeling.

I repair, then, fellow-citizens, to the post you have assigned me. With experience enough in subordinate offices to have seen the difficulties of this the greatest of all, I have learnt to expect that it will rarely fall to the lot of imperfect man to retire from this station with the reputation and the favor which bring him into it.

Not content with real sufferings, the anxious man imposes imaginary ones on himself; he is a being for whom unreality exists, must exist; otherwise where would he obtain the ration of torment his nature demands?

If we cannot "practice the presence of God," it is something to practice the absence of God, to become increasingly aware of our unawareness till we feel like man who should stand beside a great cataract and hear no noise, or like a man in a story who looks in a mirror and finds no face there, or a man in a dream who stretches his hand to visible objects and gets no sensation of touch. To know that one is dreaming is to no longer be perfectly asleep. Bur for news of the fully waking world you must go to my betters.

In the same way as philosophy loses sight of its true object and appropriate matter, when either it passes into and merges in theology, or meddles with external politics, so also does it mar its proper form when it attempts to mimic the rigorous method of mathematics.

Those who have a well-ordered character lead also a well-ordered life.

We are in hell and I will have my turn!

Perhaps then we must begin with such facts as are known to us from individual experience. It is necessary therefore that the person who is to study, with any tolerable chance of profit, the principles of nobleness and justice and politics generally, should have received a good moral training.

If self-knowledge does not lead to knowing oneself before God - well, then there is something to what purely human self-observation says, namely, this self-knowledge leads to a certain emptiness that produces dizziness. Only by being before God can one totally come to oneself in the transparency of soberness.

Writing is hard work. The fact that I love doing it doesn't make it less hard work. People who love tennis will sweat themselves to exhaustion playing it, and the love of the game doesn't stop the sweating. The casual assumption that writers are unemployed bums because they don't go to the office and don't have a boss is something every writer has to live with. I have never known a writer who hasn't suffered as a result of this, hasn't resented it, and hasn't dreamed of murdering the next person who says "Boy, you've sure got it made. You just sit there and toss off a story or something whenever you feel like it."

What was was ever, and ever shall be. For, if it had come into being, it needs must have been nothing before it came into being. Now, if it were nothing, in no wise could anything have arisen out of nothing.

What is necessary at this stage in our evolution is not a 'return' to the psychic powers of our ancestors, but an expansion of our own potential powers, based upon the certain knowledge that such powers exist.

Each pursues his private interest and only his private interest; and thereby serves the private interests of all, the general interest, without willing it or knowing it. The real point is not that each individual's pursuit of his private interest promotes the totality of private interests, the general interest. One could just as well deduce from this abstract phrase that each individual reciprocally blocks the assertion of the others' interests, so that, instead of a general affirmation, this war of all against all produces a general negation.

The ideal of strictly scientific method in mathematics which I have tried to realise here, and which perhaps might be named after Euclid I should like to describe in the following way... The novelty of this book does not lie in the content of the theorems but in the development of the proofs and the foundations on which they are based... With this book I accomplish an object which I had in view in my Begriffsschrift of 1879 and which I announced in my Grundlagen der Arithmetik. I am here trying to prove the opinion on the concept of number that I expressed in the book last mentioned.

Skepticism, like chastity, should not be relinquished too readily.

The gods sell anything to everybody at a fair price.
