If there is anything unique about the human animal it is that it has the ability to grow knowledge at an accelerating rate while being chronically incapable of learning from experience. Science and technology are cumulative, whereas ethics and politics deal with recurring dilemmas. Whatever they are called, torture and slavery are universal evils; but these evils cannot be consigned to the past like redundant theories in science. They return under different names: torture as enhanced interrogation techniques, slavery as human trafficking. Any reduction in universal evils is an advance in civilization. But, unlike scientific knowledge, the restraints of civilized life cannot be stored on a computer disc. They are habits of behaviour, which once broken are hard to mend. Civilization is natural for humans, but so is barbarism.

We now live in a technologically prepared environment that blankets the earth itself. The humanly contrived environment of electric information and power has begun to take precedence over the old environment of "nature." Nature, as it were, begins to be the content of our technology.

Philosophy is the childhood of the intellect, and a culture that tries to skip it will never grow up.

It is a double-edged makeshift to entrust an individual or a group of individuals with the authority to resort to violence. The enticement implied is too tempting for a human being. The men who are to protect the community against violent aggression easily turn into the most dangerous aggressors. They transgress their mandate. They misuse their power for the oppression of those whom they were expected to defend against oppression. The main political problem is how to prevent the police power from becoming tyrannical. This is the meaning of all the struggles for liberty.

If our universe is one of many, unlike others in containing observers like ourselves, there is no need to posit a designer. Most universes will be too chaotic to allow the emergence of life or mind. In that case, the fact that humans exist in this universe needs no special explanation.

He who should teach men to die would at the same time teach them to live.

Scientific beliefs are supported by evidence, and they get results. Myths and faiths are not and do not.

World War I a railway war of centralization and encirclement. World War II a radio war of decentralization concluded by the Bomb. World War III a TV guerrilla war with no divisions between civil and military fronts.

The aspects of things that are most important for us are hidden because of their simplicity and familiarity. (One is unable to notice something - because it is always before one's eyes.) The real foundations of his enquiry do not strike a man at all. Unless that fact has at some time struck him. - And this means: we fail to be struck by what, once seen, is most striking and most powerful.

This perversion of the ethical values soon crystallized into the all-dominating slogan of the Communist Party: THE END JUSTIFIES ALL MEANS. Similarly in the past the Inquisition and the Jesuits adopted this motto and subordinated to it all morality. It avenged itself upon the Jesuits as it did upon the Russian Revolution. In the wake of this slogan followed lying, deceit, hypocrisy and treachery, murder, open and secret. It should be of utmost interest to students of social psychology that two movements as widely separated in time and ideas as Jesuitism and Bolshevism reached exactly similar results in the evolution of the principle that the end justifies all means. The historic parallel, almost entirely ignored so far, contains a most important lesson for all coming revolutions and for the whole future of mankind.

It's also been attacked from the left by people... I teach students at Stanford, and many of them think that liberalism is... the doctrine of their parents' or their grandparents' generation, but it's really not relevant to Gen Z younger people who are impatient for social justice and social change that liberalism is not providing.

For as when much superfluous matter has gathered in simple bodies, nature makes repeated efforts to remove and purge it away, thereby promoting the health of these bodies, so likewise as regards that composite body the human race, when every province of the world so teems with inhabitants that they can neither subsist where they are nor remove elsewhere, every region being equally crowded and over-peopled, and when human craft and wickedness have reached their highest pitch, it must needs come about that the world will purge herself in one or another of these three ways, to the end that men, becoming few and contrite, may amend their lives and live with more convenience.

Scientists have pushed back the horizon of time from the biblical 6,000 years to 4,600,000,000 years for the age of Earth a 760,000-fold increase.

Americans cleave to the things of this world as if assured that they will never die,... They clutch everything but hold nothing fast, and so lose grip as they hurry after some new delight. ... Death steps in in the end and stops him before he has grown tired of this futile pursuit of that complete felicity which always escapes him. At first sight there is something astonishing in this spectacle of so many lucky men restless in the midst of abundance. But it is a spectacle as old as the world; all that is new is to see a whole people performing in it.

That a woman is presented as a teacher, as a prototype of piety, cannot amaze anyone who knows that piety or godliness is fundamentally womanliness. ... from a woman you learn concern for the one thing needful, from Mary, sister of Lazarus, who sat silent at Christ's feet with her heart's choice: the one thing needful.

Nonviolence is not an absolute principle, but an open-ended struggle with violence and its countervailing forces.

What's interesting about the world today is that the fundamental division is... a... sociological one between people that have better educations, that live in big urban agglomerations, that then can then benefit from... a global economy, versus people who live in... smaller cities and towns, or in the countryside... with more traditional values. That division exists almost universally, in Turkey... Hungary... the United States, in Britain... It does reflect different economic opportunities, but more fundamentally... it reflects a... way of life, that in the urban case is... liberal and open, but in some cases... people would say a little... too open and too tolerant of... people that want to break traditional norms that are still maintained by... other parts of the population. So it's really that cultural fight... that's at the center of populism, related to,.. but certainly not fundamentally driven by economic inequality.

Money is the password, and all doors, which are closed to the man of lesser means, fly open to those whom Plutus favors. The invention of money, which has no other usefulness (or at least it should not have any) except for the commercial exchange of the products of man's industry, now serves all that is physically good among men. Especially after money was represented by metal, it has produced avarice which, finally, without indulgence, but by its mere possession, and even with the resolution (of the stingy) not to spend it, still contains a power which people believe can sufficiently compensate for the lack of any other power.

May it not be the fact that mankind, who after all are made up of single human beings, obtain a greater sum of happiness when each pursues his own, under the rules and conditions required by the good of the rest, than when each makes the good of the rest his only object, and allows himself no personal pleasures not indispensable to the preservation of his faculties? The regimen of a blockaded town should be cheerfully submitted to when high purposes require it, but is it the ideal perfection of human existence?

Our "Theories of Taste," as they are called, wherein the deep, infinite, unspeakable Love of Wisdom and Beauty, which dwells in all men, is "explained," made mechanically visible, from "Association" and the like, ...

This heaven will pass away, and the one above it will pass away. The dead are not alive, and the living will not die. In the days when you consumed what is dead, you made it what is alive. When you come to dwell in the light, what will you do? On the day when you were one you became two. But when you become two, what will you do?

Is it reasonable to assume a purposiveness in all the parts of nature and to deny it to the whole?

There is no objective reality. But there is only an illusion of consciousness, there is only an objectivication of reality, which was created by the spirit. The origin of life is creativity, freedom; and the personality, subject, and spirit are the representatives of that origin, but not the nature, not the object.

A political, economic, and social order created merely for the sake of temporal life is exclusively characteristic of the modern world, that is, of the antitraditional world.

Mercantile jealousy is excited, and both inflames, and is itself inflamed, by the violence of national animosity.

You take souls for vegetables.... The gardener can decide what will become of his carrots but no one can choose the good of others for them.

The pathos of it all is that the America which is to be protected by a huge military force is not the America of the people, but that of the privileged class; the class which robs and exploits the masses, and controls their lives from the cradle to the grave. No less pathetic is it that so few people realize that preparedness never leads to peace, but that it is indeed the road to universal slaughter.

Nor is there any embarrassment in the fact that we're ridiculous, isn't it true? For it's actually so, we are ridiculous, light-minded, with bad habits, we're bored, we don't know how to look, how to understand, we're all like that, all, you, and I, and they! Now, you're not offended when I tell you to your face that you're ridiculous? And if so, aren't you material? You know, in my opinion it's sometimes even good to be ridiculous, if not better: we can the sooner forgive each other, the sooner humble ourselves; we can't understand everything at once, we can't start right out with perfection! To achieve perfection, one must first begin by not understanding many things! And if we understand too quickly, we may not understand well. This I tell you, you, who have already been able to understand. .. and not understand ... so much. I'm not afraid for you now.

Lycurgus the Lacedæmonian brought long hair into fashion among his countrymen, saying that it rendered those that were handsome more beautiful, and those that were deformed more terrible. To one that advised him to set up a democracy in Sparta, "Pray," said Lycurgus, "do you first set up a democracy in your own house."

When the intensity of emotional conviction subsides, a man who is in the habit of reasoning will search for logical grounds in favour of the belief which he finds in himself.

In a revolution, as in a novel, the most difficult part to invent is the end.

Most of what we strive for in our modern life uses the apparatus of goal seeking that was originally set up to seek goals in the state of nature.

The decisions of law courts should never be printed: in the long run, they form a counterauthority to the law.

Know that death comes to everyone, and that wealth will sometimes be acquired, sometimes lost. Whatever griefs mortals suffer by divine chance, whatever destiny you have, endure it and do not complain. But it is right to improve it as much as you can, and remember this: Fate does not give very many of these griefs to good people.

Mind, even more deadly to empires than to individuals, erodes them, compromises their solidity.

It is the fate of 'little faiths' of truth that they, true followers of Peter, whether they be Roman or the Protestant observance, cry out and sink in the sea of ideas, where the followers of Paul, believing in the Spirit, walk secure and undismayed.

We distinguish diagrammatic from sentential paper-and-pencil representations of information by developing alternative models of information-processing systems that are informationally equivalent and that can be characterized as sentential or diagrammatic. Sentential representations are sequential, like the propositions in a text. Diagrammatic representations are indexed by location in a plane. Diagrammatic representations also typically display information that is only implicit in sentential representations and that therefore has to be computed, sometimes at great cost, to make it explicit for use. We then contrast the computational efficiency of these representations for solving several.illustrative problems in mathematics and physics.

There can be no brotherhood when some nations indulge in previously unheard of luxuries, while others struggle to stave off famine.

No man has ever been so far advanced by Fortune that she did not threaten him as greatly as she had previously indulged him.

For a large class of cases - though not for all - in which we employ the word meaning it can be explained thus: the meaning of a word is its use in the language.

...they cudgel their brains with absurd questions, such as, for instance, why God did not make the world many centuries earlier. They persuade themselves that it is easy to conceive, to be sure, how God may discern what is present, that is, what is actual in the time in which he is, but how He may foresee what is future, that is, what is actual in the time in which He is not yet, they deem an intellectual difficulty; as if the existence of the Necessary Being descended through all the moments of an imaginary time, and, having already exhausted a part of His duration, saw before Him the eternity He was yet to live simultaneously with the present events of the world. All these difficulties upon proper insight into the notion of time vanish like smoke.

Generally speaking there is no irreducible taste or inclination. They all represent a certain appropriative choice of being. It is up to existential psychoanalysis to compare and classify them. Ontology abandons us here; it has merely enabled us to determine the ultimate ends of human reality, its fundamental possibilities, and the value which haunts it.

What has the Church done to thee, that thou shouldst wish to decapitate her? Thou wouldst take away her Head, and believe in the Head alone, despising the body. Vain is thy service, and false thy devotion to the Head. For to sever it from the body is an injury to both Head and body.

Money is not required to buy one necessity of the soul.

The nineteenth century, utilitarian throughout, set up a utilitarian interpretation of the phenomenon of life which has come down to us and may still be considered as the commonplace of everyday thinking. ... An innate blindness seems to have closed the eyes of this epoch to all but those facts which show life as a phenomenon of utility.

The fear of death is more to be dreaded than death itself.

An international socialism is the stated ideal of most socialists; an international liberalism is the unstated tendency of the liberal. To neither system is it thinkable that men live, not by universal aspirations but by local attachments; not by a "solidarity" that stretches across the globe from end to end, but by obligations that are understood in terms which separate men from most of their fellows-in terms such as national history, religion, language, and the customs that provide the basis of legitimacy.
