If you don't want to explode with rage, leave your memory alone, abstain from burrowing there.

It depends on what we read, after all manner of Professors have done their best for us.

The whole title by which you possess your property, is not a title of nature but of a human institution.

Christianity is at the very root of the evil that has corrupted the West. This is the truth, and it admits no doubt.

Great men, great nations, have not been boasters and buffoons, but perceivers of the terror of life, and have manned themselves to face it.

I have found a paper of mine among some others in which I call architecture 'petrified music.' Really there is something in this; the tone of mind produced by architecture approaches the effect of music.

Understand then all of you, especially the young, that to want to impose an imaginary state of government on others by violence is not only a vulgar superstition, but even a criminal work. Understand that this work, far from assuring the well-being of humanity is only a lie, a more or less unconscious hypocrisy, camouflaging the lowest passions we possess.

The principal aim of mathematical education is to develop certain faculties of the mind, and among these intuition is not the least precious. It is through it that the mathematical world remains in touch with the real world, and even if pure mathematics could do without it, we should still have to have recourse to it to fill up the gulf that separates the symbol from reality.

The world at present is obsessed by the conflict of rival ideologies, and one of the apparent causes of conflict is the desire for the victory of our own ideology and the defeat of the other. I do not think that the fundamental motive here has much to do with ideologies. I think the ideologies are merely a way of grouping people, and that the passions involved are merely those which always arise between rival groups. Ideologies, in fact, are one of the methods by which herds are created, and the psychology is much the same however the herd may have been generated.

Whether or not birth control is eugenic, hygienic, and economic, it is the most revolutionary practice in the history of sexual morals.

Look for yourself, and you will find in the long run only hatred, loneliness, despair, rage, ruin, and decay. But look for Christ and you will find Him, and with Him everything else thrown in.

In the visible world, the Milky Way is a tiny fragment; within this fragment, the solar system is an infinitesimal speck, and of this speck our planet is a microscopic dot. On this dot, tiny lumps of impure carbon and water, of complicated structure, with somewhat unusual physical and chemical properties, crawl about for a few years, until they are dissolved again into the elements of which they are compounded. They divide their time between labour designed to postpone the moment of dissolution for themselves and frantic struggles to hasten it for others of their kind.

My father was as well aware as anyone that Christians do not, in general, undergo the demoralizing consequences which seem inherent in such a creed, in the manner or to the extent which might have been expected from it. The same slovenliness of thought, and subjection of the reason to fears, wishes, and affections, which enable them to accept a theory involving a contradiction in terms, prevents them from perceiving the logical consequences of the theory. Such is the facility with which mankind believe at one and the same time things inconsistent with one another, and so few are those who draw from what they receive as truths, any consequences but those recommended to them by their feelings, that multitudes have held the undoubting belief in an Omnipotent Author of Hell, and have nevertheless identified that being with the best conception they were able to form of perfect goodness.

Nature admits no lie.

He who is not sure of his memory, should not undertake the trade of lying. 

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.

I assert once again as a truth to which history as a whole bears witness that men may second their fortune, but cannot oppose it; that they may weave its warp, but cannot break it. Yet they should never give up, because there is always hope, though they know not the end and more towards it along roads which cross one another and as yet are unexplored; and since there is hope, they should not despair, no matter what fortune brings or in what travail they find themselves.

The reason that I call my doctrine logical atomism is because the atoms that I wish to arrive at as the sort of last residue in analysis are logical atoms and not physical atoms. Some of them will be what I call "particulars" - such things as little patches of color or sounds, momentary things - and some of them will be predicates or relations and so on.

But the exceedingly foul deed of Onan, the basest of wretches, follows. Onan must have been a malicious and incorrigible scoundrel. This is a most disgraceful sin. It is far more atrocious than incest and adultery. We call it unchastity, yes a Sodomitic sin. For Onan goes in to her; that is, he lies with her and copulates, and when it comes to the point of insemination, spills the semen, lest the woman conceive. Surely at such a time the order of nature established by God in procreation should be followed. Accordingly, it was a most disgraceful crime to produce semen and excite the woman, and to frustrate her at that very moment.

The crop of spiritual talent that is born to you, of human nobleness and intellect and heroic faculty, this is infinitely more important than your crops of cotton or corn, or wine or herrings or whale-oil, which the Newspapers record with such anxiety every season.

Logic takes care of itself; all we have to do is to look and see how it does it.

Limiting the liberty of each by the like liberty of all, excludes a wide range of improper actions, but does not exclude certain other improper ones.

You have heard that it was said, "Eye for eye, and tooth for tooth." But I tell you, do not resist an evil person. If someone strikes you on the right cheek, turn to him the other also. And if someone wants to sue you and take your tunic, let him have your cloak as well. If someone forces you to go one mile, go with him two miles.

I do not believe that the source of value is unitary - displaying apparent multiplicity only in its application to the world. I believe that value has fundamentally different kinds of sources, and that they are reflected in the classification of values into types. Not all values represent the pursuit of some single good in a variety of settings.

It is our interest and our task to make the revolution permanent until all the more or less propertied classes have been driven from their ruling positions, until the proletariat has conquered state power and until the association of the proletarians has progressed sufficiently far - not only in one country but in all the leading countries of the world - that competition between the proletarians of these countries ceases and at least the decisive forces of production are concentrated in the hands of the workers. Our concern cannot simply be to modify private property, but to abolish it, not to hush up class antagonisms but to abolish classes, not to improve the existing society but to found a new one.

Placing your stick at the end of the shadow of the pyramid, you made by the sun's rays two triangles, and so proved that the pyramid [height] was to the stick [height] as the shadow of the pyramid to the shadow of the stick.

What is the wisdom of a book compared with the wisdom of an angel?

In the immense sphere of living things, the obvious rule is violence, a kind of inevitable frenzy which arms all things in mutua funera. Once you leave the world of insensible substances, you find the decree of violent death written on the very frontiers of life. Even in the vegetable kingdom, this law can be perceived: from the huge catalpa to the smallest of grasses, how many plants die and how many are killed!

It was not delight, not wonder that arose among us, it was the peace of heaven. A thousand times have I said it to her and to myself: the most beautiful is also the most sacred. And such was everything in her. Like her singing, even so was her life.

If the inner psychic ground of our individual appearance were not always the same, there could be no science of psychology, which qua science relies on a psychic "inside we are all alike," just as the science of physiology and medicine relies on the sameness of our inner organs. The monstrous sameness and pervasive ugliness so highly characteristic of the findings of modern psychology, and contrasting so obviously with the enormous variety and richness of overt human conduct, witness to the radical difference between the inside and the outside of the human body.

Success makes some crimes honorable.

Perhaps no person can be a poet, or even enjoy poetry, without a certain unsoundness of mind.

The principle of brotherhood expounded by the agitator of Nazareth preserved the germ of life, of truth and justice, so long as it was the beacon light of the few. The moment the majority seized upon it, that great principle became a shibboleth and harbinger of blood and fire, spreading suffering and disaster. The attack on the omnipotence of Rome was like a sunrise amid the darkness of the night, only so long as it was made by the colossal figures of a Huss, a Calvin, or a Luther. Yet when the mass joined in the procession against the Catholic monster, it was no less cruel, no less bloodthirsty than its enemy. Woe to the heretics, to the minority, who would not bow to its dicta. After infinite zeal, endurance, and sacrifice, the human mind is at last free from the religious phantom; the minority has gone on in pursuit of new conquests, and the majority is lagging behind, handicapped by truth grown false with age.

And to bring in a new word by the head and shoulders, they leave out the old one.

There is one mistake we got to avoid, and that is the mistake of supposing that if you simulate it, you duplicate it. This is a deep mistake embedded in our popular culture - that simulation is equivalent to duplication, but of course it isn't. A perfect simulation of the brain - say, on a computer - would no longer thereby be conscious than a perfect simulation of a rainstorm on a weather-predicting computer will leave us all wet.

I find that the best goodness I have has some tincture of vice.

This is the pure form of servitude: to exist as an instrument.

Every good thing is gentle and consistent, progressing in good order and not going beyond what is right.

That which comes after ever conforms to that which has gone before.

I simply don't think it is reasonable to use IQ tests to produce results of questionable value, which may then serve to justify racists in their own minds and to help bring about the kinds of tragedies we have already witnessed earlier in this century.

A man, an adult, is precisely what [Aeneas] is: Achilles had been little more than a passionate boy.

The individual who is subordinate to an objective law feels himself determined by it, while he, in turn, in no way determines the law, and has no possibility of reacting to it in a manner which could influence it-quite in contrast to even the most miserable slave, who, in some fashion at last, can still in this sense react to his master.

Where the preamble declares, that coercion is a departure from the plan of the holy author of our religion, an amendment was proposed by inserting "Jesus Christ," so that it would read "A departure from the plan of Jesus Christ, the holy author of our religion;" the insertion was rejected by the great majority, in proof that they meant to comprehend, within the mantle of its protection, the Jew and the Gentile, the Christian and Mohammedan, the Hindoo and Infidel of every denomination.

Yes, truly, it is a great thing for a Nation that it get an articulate voice; that it produce a man who will speak forth melodiously what the heart of it means!

All war propaganda consists, in the last resort, in substituting diabolical abstractions for human beings. Similarly, those who defend war have invented a pleasant sounding vocabulary of abstractions in which to describe the process of mass murder.

Wherever we turn we find that the real obstacles to peace are human will and feeling, human convictions, prejudices, opinions. If we want to get rid of war we must get rid first of all of its psychological causes. Only when this has been done will the rulers of the nations even desire to get rid of the economic and political causes.
