Nicias, do you think you can erase with good deeds the wrongs you committed against your mother? What good deed will ever reach her? Her soul is a scorching noon time, without a single breath of a breeze, nothing moves, nothing changes, nothing lives there; a great emaciated sun, an immobile sun eternally consumes her.

Thinking is an expedition into quietness.

We do not have and cannot have any means of discovering whether or not we are carried along in a uniform motion of translation.

He that will have his son have a respect for him and his orders, must himself have a great reverence for his son.

Gottlob Frege created modern logic including "for all," "there exists," and rules of proof. Leibniz and Boole had dealt only with what we now call "propositional logic" (that is, no "for all" or "there exists"). They also did not concern themselves with rules of proof, since their aim was to reach truth by pure calculation with symbols for the propositions. Frege took the opposite track: instead of trying to reduce logic to calculation, he tried to reduce mathematics to logic, including the concept of number.

Underlying even the so-called problem of knowledge there is simply this human feeling, just as underlying the inquiry into the "why," the cause, there is simply the search for the "wherefore," the end. All the rest is either to deceive oneself or to wish to deceive others; and to wish to deceive others in order to deceive oneself.

A person who wakes up after a night of unbroken sleep has the illusion of beginning something new. When one instead remains awake the whole night long, nothing new begins.

The seeds of heavenly bodies are deposited and cared for in the Milky Way, from which they emanate in swarms of comets that travel a ;long time and ordinarily gravitate towards various suns before becoming fixed in orbit.

I am entirely of the opinion that the papacy is the Antichrist. But if anyone wants to add the Turk, then the Pope is the spirit of the Antichrist, and the Turk is the flesh of the Antichrist. They help each other in their murderous work. The latter slaughters bodily and by the sword, the former spiritually and by doctrine.

You, your families, your friends and your countries are to be exterminated by the common decision of a few brutal but powerful men. To please these men, all the private affections, all the public hopes, all that has been achieved in art, and knowledge and thought and all that might be achieved hereafter is to be wiped out forever. Our ruined lifeless planet will continue for countless ages to circle aimlessly round the sun unredeemed by the joys and loves, the occasional wisdom and the power to create beauty which have given value to human life.

We must be clear that when it comes to atoms, language can be used only as in poetry. The poet, too, is not nearly so concerned with describing facts as with creating images and establishing mental connections.

If reason (I mean abstract reason, derived from inquiries a priori) be not alike mute with regard to all questions concerning cause and effect, this sentence at least it will venture to pronounce, That a mental world, or universe of ideas, requires a cause as much, as does a material world, or universe of objects; and, if similar in its arrangement, must require a similar cause. For what is there in this subject, which should occasion a different conclusion or inference? In an abstract view, they are entirely alike; and no difficulty attends the one supposition, which is not common to both of them.

The rest of the story, to Grand's thinking, was very simple. The common lot of married couples. You get married, you go on loving a bit longer, you work. And you work so hard that it makes you forget to love.

Do not ask who I am and do not ask me to remain the same: leave it to our bureaucrats and our police to see that our papers are in order. At least spare us their morality when we write.

I don't deserve a share in governing a hen-roost, much less a nation. Nor do most people - all the people who believe advertisements, and think in catchwords and spread rumors. The real reason for democracy is just the reverse. Mankind is so fallen that no man can be trusted with unchecked power over his fellows. Aristotle said that some people were only fit to be slaves. I do not contradict him. But I reject slavery because I see no men fit to be masters.

So long as men worship the Caesars and Napoleons, Caesars and Napoleons will duly rise and make them miserable.

It is often better for a person to recognize a sin than to do a good deed. Recognizing a sin makes a person humble. Doing a good deed often can feed a person's pride.

The old land is still the true love, the others are but pleasant infidelities.

If a lion could talk, we could not understand him.

A new moral outlook is called for in which submission to the powers of nature is replaced by respect for what is best in man. It is where this respect is lacking that scientific technique is dangerous.

The rapid development of science... has, as it were, burst its old shell, now become too narrow.

If you act externally with men in conformity with your rank, you should recognize, by a more secret but truer thought, that you have nothing naturally superior to them.

To conceive the good, in fact, is not sufficient; it must be made to succeed among men. To accomplish this less pure paths must be followed.

We do not think good metaphors are anything very important, but I think that a good metaphor is something even the police should keep an eye on...

There is no general reason to expect evolution to be progressive - even in the weak, value-neutral sense. There will be times when increased size of some organ is favoured and other times when decreased size is favoured. Most of the time, average-sized individuals will be favoured in the population and both extremes will be penalised. During these times the population exhibits evolutionary stasis (i.e., no change) with respect to the factor being measured. If we had a complete fossil record and looked for trends in some particular dimension, such as leg length, we would expect to see periods of no change alternating with fitful continuations or reversals in direction - like a weathervane in changeable, gusty weather.

Dispose thy Soul to all good and necessary things!

Philosophy is a hypothetical interpretation of the unknown (as in metaphysics), or of the inexactly known (as in ethics or political philosophy); it is the front trench in the siege of 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.

What strength belongs to every plant and animal in nature. The tree or the brook has no duplicity, no pretentiousness, no show. It is, with all its might and main, what it is, and makes one and the same impression and effect at all times. All the thoughts of a turtle are turtles, and of a rabbit, rabbits. But a man is broken and dissipated by the giddiness of his will; he does not throw himself into his judgments; his genius leads him one way but 't is likely his trade or politics in quite another.

Hope is a good breakfast, but it is a bad supper.

The political freedom of conscience and of the press, so far from being as it is commonly supposed an extension, is a new case of the limitation of rights and discretion. Conscience and the press ought to be unrestrained, not because men have a right to deviate from the exact line that duty prescribes, but because society, the aggregate of individuals, has no right to assume the prerogative of an infallible judge, and to undertake authoritatively to prescribe to its members in matters of pure speculation.

The moral things I wish to say to future generations is very simple. I should say love is wise hatred is foolish. In this world which is getting more and more closely interconnected, we have to learn to tolerate each other. We have to learn to put up with the fact that some people say things that we don't like. We can only live together in that way, and if we are to live together and not die together we must learn the kind of charity and kind of tolerance which is absolutely vital to the continuation of human life on this planet.

We say in popular speech that we come into this world, but we do nothing of the kind. We come out of it. In the same way as the fruit comes out of the tree, the egg from the chicken, and the baby from the womb, we are symptomatic of the universe. Just as in the retina there are myriads of little nerve endings, we are the nerve endings of the universe.

The unbeliever walks for a quadrillion miles, yet one moments of reality makes up for it.

The wheel may be one of those cases where the engineering solution can be seen in plain view, yet be unattainable in evolution because it lies on the other side of a deep valley, cutting unbridgeably across the massif of Mount Improbable.

Frazer is much more savage than most of his savages, for they are not as far removed from the understanding of spiritual matter as a twentieth-century Englishman. His explanations of primitive practices are much cruder than the meaning of these practices themselves.

It is quite clear to you that all the people see that lower kinds of creation could have been made in a different way from that in which they really are, and as they see this lower degree in many things they think that they must have been made by chance.

Unlike the masses, intellectuals have a taste for rationality and an interest in facts.

As if there could be true stories: things happen in one way, and we retell them in the opposite way.

If throughout your life you abstain from murder, theft, fornication, perjury, blasphemy, and disrespect toward your parents, your church, and your king, you are conventionally held to deserve moral admiration even if you have never done a single kind or generous or useful action. This very inadequate notion of virtue is an outcome of taboo morality, and has done untold harm.

In the land of the blind the one-eyed man is lord.

The definition of definition is at bottom just what the maxim of pragmatism expresses.

It seldom happens, however, that a great proprietor is a great improver.

Even the free importation of foreign corn could very little affect the interest of the farmers of Great Britain. Corn is a much more bulky commodity than butcher's-meat. A pound of wheat at a penny is as dear as a pound of butcher's-meat at fourpence. The small quantity of foreign corn imported even in times of the greatest scarcity, may satisfy our farmers that they can have nothing to fear from the freest importation.

Everything considered, a determined soul will always manage.

When God chooses to let himself be born in lowliness, when he who holds all possibilities in his hand takes upon himself the form of a lowly servant, when he goes about defenseless and lets people do with him what they will, he surely must know well enough what he is doing and why he wills it; but for all that it is he who has people in his power and not they who have power over him-so history ought not play Mr. Malapert by this wanting to make manifest who he was.

For a good cause, wrongdoing is virtuous.

A fire eater must eat fire even if he has to kindle it himself.

Denotation by means of sounds and markings is a remarkable abstraction. Three letters designate God for me; several lines a million things. How easy becomes the manipulation of the universe here, how evident the concentration of the intellectual world! Language is the dynamics of the spiritual realm. One word of command moves armies; the word Liberty entire nations.
