The rules of logic are to mathematics what those of structure are to architecture.

The human soul has need of disciplined participation in a common task of public value, and it has need of personal initiative within this participation. The human soul has need of security and also of risk. The fear of violence or of hunger or of any other extreme evil is a sickness of the soul. The boredom produced by a complete absence of risk is also a sickness of the soul.

When, in the course of human development, existing institutions prove inadequate to the needs of man, when they serve merely to enslave, rob, and oppress mankind, the people have the eternal right to rebel against, and overthrow, these institutions.

Martyrs create faith, faith does not create martyrs.

A truly powerful holder of power does not simply elicit agreement, but enthusiasm and excitement.

No one has yet been found so firm of mind and purpose as resolutely to compel himself to sweep away all theories and common notions, and to apply the understanding, thus made fair and even, to a fresh examination of particulars. Thus it happens that human knowledge, as we have it, is a mere medley and ill-digested mass, made up of much credulity and much accident, and also of the childish notions which we at first imbibed.

The soul active sees absolute truth; and utters truth, or creates.

476 ... is usually taken as the date of the "fall of the Roman Empire." The date, however, is a false one. No one at this period of time considered that the Roman Empire had "fallen." Indeed, it still existed and was the most powerful realm in Europe. Its capital was at Constantinople and the Emperor was Zeno. It is only because we ourselves are culturally descended from the Roman west, that we tend to ignore the continued existence of the Roman Empire in the east.

In art the Chinese aim at being exquisite, and in life at being reasonable.

I do not mean to deny the biologic, physiologic, or psychologic factors in creating crime; but there is hardly an advanced criminologist who will not concede that the social and economic influences are the most relentless, the most poisonous germs of crime.

His Religion is not an easy one: with rigorous fasts, lavations, strict complex formulas, prayers five times a day, and abstinence from wine, it did not "succeed by being an easy religion." As if indeed any religion, or cause holding of religion, could succeed by that! It is a calumny on men to say that they are roused to heroic action by ease, hope of pleasure, recompense, - sugar-plums of any kind, in this world or the next! In the meanest mortal there lies something nobler.

The wife of my God is matter; they wrestle with each other, they laugh and weep, they cry out in the nuptial bed of flesh. They spawn and are dismembered. They fill sea, land, and air with species of plants, animals, men, and spirits. This primordial pair embraces, is dismembered, and multiplies in every living creature. All the concentrated agony of the Universe bursts out in every living thing. God is imperiled in the sweet ecstasy and bitterness of flesh. But he shakes himself free, he leaps out of brains and loins, then clings to new brains and new loins until the struggle for liberation again breaks out from the beginning.

The sin of pride may be a small or a great thing in someone's life, and hurt vanity a passing pinprick or a self-destroying or even murderous obsession. Possibly, more people kill themselves and others out of hurt vanity than out of envy, jealousy, malice or desire for revenge.

The attitude that living things are placed here for our benefit still dominates our culture, even where its underpinnings have disappeared. We now need, for purposes of scientific understanding, to find a less human-centered view of the natural world.

Whereas materialistic historians and philosophers neglect psychic realities, Freud is inclined to overstress their importance. I am not a psychologist, but it seems to me fairly evident that physiological factors, especially our endocrines, control our destiny ... I am not able to venture a judgment on so important a phase of modern thought. However, it seems to me that psychoanalysis is not always salutary. It may not always be helpful to delve into the subconscious. The machinery of our legs is controlled by a hundred different muscles. Do you think it would help us to walk if we analyzed our legs and knew exactly which one of the little muscles must be employed in locomotion and the order in which they work? ... I am not prepared to accept all his [Freud's] conclusions, but I consider his work an immensely valuable contribution to the science of human behavior. I think he is even greater as a writer than as a psychologist. Freud's brilliant style is unsurpassed by anyone since Schopenhauer.

First then, we find that when we regard ideas from a nominalistic, individualistic, sensualistic way, the simplest facts of mind become utterly meaningless. That one idea should resemble another or influence another, or that one state of mind should so much as be thought of in another is, from that standpoint, sheer nonsense.

The perception of the comic is a tie of sympathy with other men, a pledge of sanity, and protection from those perverse tendencies and gloomy insanities in which fine intellects sometimes lose themselves. A rogue alive to the ludicrous is still convertible.

The modern scientific counterpart to belief in God is the belief in the universe as an organism: this disgusts me. This is to make what is quite rare and extremely derivative, the organic, which we perceive only on the surface of the earth, into something essential, universal, and eternal! This is still an anthropomorphizing of nature!

For in every country of the world, I believe, the avarice and injustice of princes and sovereign states, abusing the confidence of their subjects, have by degrees diminished the real quantity of metal, which had been originally contained in their coins.

The middle sort of historians (of which the most part are) spoil all; they will chew our meat for us.

For the kingdom of heaven is with us today.

When I was a boy, I had a clock with a pendulum that could be lifted off. I found that the clock went very much faster without the pendulum. If the main purpose of a clock is to go, the clock was the better for losing its pendulum. True, it could no longer tell the time, but that did not matter if one could teach oneself to be indifferent to the passage of time. The linguistic philosophy which cares only about language and not about the world, is like the boy who preferred the clock without the pendulum because, although it no longer told the time, it went more easily than before and at a more exhilarating pace.

For a work to become immortal it must possess so many excellences that it will not be easy to find a man who understands and values them all; so that there will be in all ages men who recognise and appreciate some of these excellences; by this means the credit of the work will be retained throughout the long course of centuries and ever-changing interests, for, as it is appreciated first in this sense, then in that, the interest is never exhausted.

As we can not give a general definition of energy, the principle of the conservation of energy signifies simply that there is something which remains constant.

There are more ideas on earth than intellectuals imagine. And these ideas are more active, stronger, more resistant, more passionate than "politicians" think. We have to be there at the birth of ideas, the bursting outward of their force: not in books expressing them, but in events manifesting this force, in struggles carried on around ideas, for or against them. Ideas do not rule the world. But it is because the world has ideas (and because it constantly produces them) that it is not passively ruled by those who are its leaders or those who would like to teach it, once and for all, what it must think.

Dogmatics must be designed in this way. Above all, every science must vigorously lay hold of its own beginning and not live in complicated relations with other sciences. If dogmatics begins by wanting to explain sinfulness or by wanting to prove its actuality, no dogmatics will come out of it, but the entire existence of dogmatics will become problematic and vague.

I like thought which preserves a whiff of flesh and blood, and I prefer a thousand times an idea rising from sexual tension or nervous depression to empty abstraction.

By creating the world market, big industry has already brought all the peoples of the Earth, and especially the civilized peoples, into such close relation with one another that none is independent of what happens to the others. Further, it has co-ordinated the social development of the civilized countries to such an extent that, in all of them, bourgeoisie and proletariat have become the decisive classes, and the struggle between them the great struggle of the day. It follows that the communist revolution will not merely be a national phenomenon but must take place simultaneously in all civilized countries.

The christian religion is a parody on the worship of the Sun, in which they put a man whom they call Christ, in the place of the Sun, and pay him the same adoration which was originally paid to the Sun.

The bodies breathe, feed, store up strength, and then in an erotic moment are shattered, are spent and drained utterly, that they may bequeath their spirit to their sons. What spirit? The drive upward!

Children have as much mind to shew that they are free, that their own good actions come from themselves, that they are absolute and independent, as any of the proudest of you grown men, think of them as you please.

The Democratic Party is beyond redemption at this point when it comes to seriously speaking to the needs of poor and working people... The neofascism that's escalating is predicated on the rottenness of a system in which the Democratic Party facilitates that frustration and desperation because it can't present an alternative... If America is unable to present an alternative to the Democratic Party, then we're going fascist.

The Greek word for philosopher (philosophos) connotes a distinction from sophos. It signifies the lover of wisdom (knowledge) as distinguished from him who considers himself wise in the possession of knowledge. This meaning of the word still endures: the essence of philosophy is not the possession of the truth but the search for truth. ... Philosophy means to be on the way. Its questions are more essential than its answers, and every answer becomes a new question.

Fear? If I have gained anything by damning myself, it is that I no longer have anything to fear.

It is an odd circumstance that neither the old nor the new, by itself, is interesting; the absolutely old is insipid; the absolutely new makes no appeal at all. The old in the new is what claims the attention,-the old with a slightly new turn.

Americans need rest, but do not know it. I believe this to be a large part of the explanation of the crime wave in the United States.

The concrete man has but one interest - to be right. That to him is the art of all arts, and all means are fair which help him to it.

Thus, because Christian morals leave animals out of consideration ... therefore in philosophical morals they are of course at once outlawed; they are merely "things," simply means to ends of any sort; and so they are good for vivisection, for deer-stalking, bull-fights, horse-races, etc., and they may be whipped to death as they struggle along with heavy quarry carts. Shame on such a morality ... which fails to recognize the Eternal Reality immanent in everything that has life, and shining forth with inscrutable significance from all eyes that see the sun!

Cash Payment the sole nexus; and there are so many things which cash will not pay! Cash is a great miracle; yet it has not all power in Heaven, nor even on Earth. 'Supply and demand' we will honour also; and yet how many 'demands' are there, entirely indispensable, which have to go elsewhere than to the shops, and produce quite other than cash, before they can get their supply? On the whole, what astonishing payments does cash make in this world!

The more you make people alike, the more competition you have. Competition is based on the principle of conformity.

Society undergoes continual changes; it is barbarous, it is civilized, it is Christianized, it is rich, it is scientific; but this change is not amelioration. For everything that is given something is taken. Society acquires new arts, and loses old instincts. The civilized man has built a coach, but has lost the use of his feet; he has a fine Geneva watch, but cannot tell the hour by the sun.

All that is solid melts into air, all that is holy is profaned, and man is at last compelled to face with sober senses, his real conditions of life, and his relations with his kind.

Imagine that nature is saying to us: "Those things of which you complain are the same for all. I cannot give anything easier to any man, but whoever wishes will make things easier for himself." In what way? By equanimity. You must suffer pain, and thirst, and hunger, and old age too, if a longer stay among men shall be granted you; you must be sick, and you must suffer loss and death.

For it was my master who taught me not only how very little I knew but also that any wisdom to which I might ever aspire could consist only in realizing more fully the infinity of my ignorance.

It is a base thing for the countenance to be obedient and to regulate and compose itself as the mind commands, and for the mind not to be regulated and composed by itself.
