The plague of man is boasting of his knowledge.

Sociology does not 'negate' philosophy, in the sense of taking over the hidden content of philosophy and carrying it into social theory and practice, but sets itself up as a realm apart from philosophy, with a province and truth of its own. Comte is rightly held to be the inaugurator of this separation between philosophy and sociology.

All sources of energy upon which industry depends are wasted when they are employed; and industry is expending them at a continually increasing rate. Already coal has been largely replaced by oil, and oil is being used up so fast that East and West alike conceive it necessary to their own prosperity to destroy the industry of the other. And what is true of oil is equally true of other natural resources. Every day, many square miles of forest are turned into newspaper, but there is no known process by which newspaper can be turned into forest. You will say that this need not worry us, since newspapers will be replaced by radio, but radio requires electricity, electricity requires power, and power depends upon raw materials.

I am firmly convinced, therefore, that to set up a republic which is to last a long time, the way to set about it is to constitute it as Sparta and Venice were constituted; to place it in a strong position, and so to fortify it that no one will dream of taking it by a sudden assault; and, on the other hand, not to make it so large as to appear formidable to its neighbors. It should in this way be able to enjoy its form of government for a long time. For war is made on a commonwealth for two reasons: to subjugate it, and for fear of being subjugated by it.

Custom, then, is the great guide of human life. It is that principle alone which renders our experience useful to us, and makes us expect, for the future, a similar train of events with those which have appeared in the past. Without the influence of custom, we should be entirely ignorant of every matter of fact beyond what is immediately present to the memory and senses. We should never know how to adjust means to ends, or to employ our natural powers in the production of any effect. There would be an end at once of all action, as well as of the chief part of speculation. Variant (perhaps a paraphrase of this passage): It is not reason which is the guide of life, but custom.

No one is ignorant that there are two avenues by which opinions are received into the soul, which are its two principal powers: the understanding and the will.

God judged it better to bring good out of evil than to suffer no evil to exist.

"How then shall they have the play-games you allow them, if none must be bought for them?" I answer, they should make them themselves, or at least endeavour it, and set themselves about it. ...And if you help them where they are at a stand, it will more endear you to them than any chargeable toys that you shall buy for them.

It seems that the creative faculty, and the critical faculty, cannot exist together in their highest perfection.

Let us try to teach generosity and altruism, because we are born selfish. Let us understand what our own selfish genes are up to, because we may then at least have a chance to upset their designs, something that no other species has ever aspired to do.

He doubly benefits the needy who gives quickly. Maxim 6

I do not understand! I understand nothing! I cannot understand nor do I want to understand! I want to believe! To Believe!

If the importance of science does not lie in its constituting the whole of human knowledge, even less does it lie, in my view, in its technological applications. Science at the best is a way of coming to know, and hopefully a way of acquiring some reverence for, the wonders of nature. The philosophical study of science, at the best, has always been a way of coming to understand both some of the nature and some of the limitations of human reason. These seem to me to be sufficient grounds for taking science and philosophy of science seriously; they do not justify science worship.

We have become like the most primitive Palaeolithic man, once more global wanderers, but information gatherers rather than food gatherers. From now on the source of food, wealth and life itself will be information.

When asked why people give to beggars but not to philosophers, he replied, 'Because they expect they may become lame and blind, but never that they will become philosophers.'

If you have money, don't lend it at interest. Rather, give it to someone from whom you won't get it back.

A man discovers what he is actually worth in this world when he faces society as a man, without money, name, or powerful connections, stripped of all but his native potentialities. He soon finds that nothing has less weight than his human qualities. They are prized so low that the market does not even list them. Strict science, which acknowledges man only as a biological concept, reflects man's lot in the actual world; in himself, man is nothing more than a member of a species. In the eyes of the world, the quality of humanity confers no title to existence, nay, not even a right of sojourn. Such title must be certified by special social circumstances stipulated in documents to be presented on demand.

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.

Properties perceived in nature will depend on how one looks and how one looks depends on the economic interest one has in the resources of nature. The value of profit maximization is thus linked to reductionist systems, while the value of life and the maintenance of life is linked to holistic and ecological systems.

The three qualities of space and time reciprocally affect and qualify one another in experience. Space is inane save as occupied with active volumes. Pauses are holes when they do not accentuate masses and define figures as individuals. Extension sprawls and finally benumbs if it does not interact with place so as to assume intelligible distribution. Mass is nothing fixed. It contracts and expands, asserts and yields, according to its relations to other spatial and enduring things.... these are then the common properties of the matter of arts because there are general conditions without which an experience is not possible. As we saw earlier, the basic condition is felt relationship between doing and undergoing as the organism and environment interact.

There are some defeats more triumphant than victories.

Every good mathematician is at least half a philosopher, and every good philosopher is at least half a mathematician.

As there must be moderation in other things, so there must be moderation in self-criticism. Perpetual contemplation of our own actions produces a morbid consciousness, quite unlike that normal consciousness accompanying right actions spontaneously done; and from a state of unstable equilibrium long maintained by effort, there is apt to be a fall towards stable equilibrium, in which the primitive nature reasserts itself. Retrogression rather than progression may hence result.

Frazer's account of the magical and religious views of mankind is unsatisfactory; it makes these views look like errors.

Most of the propositions that make up the body of administrative theory today share, unfortunately, this defect of proverbs. For almost every principle one can find an equally plausible and acceptable contradictory principle.

Error is the price we pay for progress.

The believing we do something when we do nothing is the first illusion of tobacco.

Don't think money does everything or you are going to end up doing everything for money.

What do we mean by saying that existence precedes essence? We mean that man first of all exists, encounters himself, surges up in the world-and defines himself afterwards. If man as the existentialist see him is not definable, it is because to begin with he is nothing. He will not be anything until later, and then he will be what he makes of himself. Thus, there is no human nature, because there is no God to have a conception of it. Man simply is. Not that he is simply what he conceives himself to be, but he is what he wills, and as he conceives himself after already existing - as he wills to be after that leap towards existence. Man is nothing else but that which he makes of himself. That is the first principle of existentialism.

Heaven, in the production of things, is sure to be bountiful to them, according to their qualities. Hence the tree that is flourishing, it nourishes, while that which is ready to fall, it overthrows.

We are accustomed to speak of ideas as reproduced, as passed from mind to mind, as similar or dissimilar to one another, and, in short, as if they were substantial things; nor can any reasonable objection be raised to such expressions. But taking the word "idea" in the sense of an event in an individual consciousness, it is clear that an idea once past is gone forever, and any supposed recurrence of it is another idea. These two ideas are not present in the same state of consciousness, and therefore cannot possibly be compared.

Love is a severe critic. Hate can pardon more than love.

The discourse of truth is quite simply impossible. It eludes itself. Everything eludes itself, everything scoffs at its own truth, seduction renders everything elusive. The fury to unveil the truth, to get at the naked truth, the one which haunts all discourses of interpretation, the obscene rage to uncover the secret, is proportionate to the impossibility of ever achieving this. ...But this rage, this fury, only bears witness to the eternity of seduction and to the impossibility of mastering it.

The blazing evidence of immortality is our dissatisfaction with any other solution.

Karsky: I met your father last week. Are you still interested in hearing how he is doing?

Hugo: No. 

Karsky: It is very probable that you will be responsible for his death.

Hugo: It is virtually certain that he is responsible for my life. We are even.

If it is the moral right we are to look at, I say, that on every principle of moral obligation, I hold that the Jew has a right to political power.

Rhetoric, it seems, is a producer of persuasion for belief, not for instruction in the matter of right and wrong. And so the rhetorician's business is not to instruct a law court or a public meeting in matters of right and wrong, but only to make them believe.

Do a man dirt, yourself you hurt.

Historical time knows no lasting present.

Women are systematically degraded by receiving the trivial attentions which men think it manly to pay to the sex, when, in fact, men are insultingly supporting their own superiority.

If A were not allowed his better position, B would be even worse off than he is.

The empirical research of the last fifteen years on the structure of large organizations seems to confirm the hypothesis of Herbert Simon that human cognitive limits are a basic limiting factor in determining organization structures .

To repeat to yourself a thousand times a day: 'Nothing on Earth has any worth,' to keep finding yourself at the same point, to circle stupidly as a top, eternally...

The wind is blowing, adore the wind.

There is no more miserable human being than one in whom nothing is habitual but indecision.

Well, which is the most rational theory about these ten millions of species? Is it most likely that there have been ten millions of special creations? or is it most likely that, by continual modifications due to change of circumstances, ten millions of varieties have been produced, as varieties are being produced still?

Everything ideal has a natural basis and everything natural an ideal development.

The President ... may err ... Congress may decide amiss ... But if the Supreme Court is ever composed of imprudent or bad men, the Union may be plunged into anarchy or civil war.

Therefore let every Christian, yea, let the whole body of Christ everywhere cry out, despite the tribulations it endures, despite temptations and countless scandals, saying: "Preserve my soul, for I am holy; save Thy servant, O my God, that trusteth in thee" (Ps. 85:2) No, this holy one is not proud, for he trusts in God.

A hymn is the praise of God with song; a song is the exultation of the mind dwelling on eternal things, bursting forth in the voice.
