One is ashamed to say how little is needed for all men to be delivered from those calamities which now oppress them; it is only needful not to lie.

Any ethics that needs religion is bad ethics, and any religion that tries to do so is bad religion. Of course, there are plenty of both around.

Bach: a scale of tears upon which our desires for God ascend.

This fighting-shy of every obligation partly explains the phenomenon, half ridiculous, half disgraceful, Of the setting-up in our days of the platform of "youth" as youth. ... In comic fashion people call themselves "young," because they have heard that youth has more rights than obligations, since it can put off the fulfilment of these latter to the Greek Kalends of maturity. ...[T]he astounding thing at present is that these take it as an effective right precisely in order to claim for themselves all those other rights which only belong to the man who has already done something.

No one realizes how beautiful it is to travel until he comes home and rests his head on his old, familiar pillow.

Life is possible only by the deficiencies of our imagination and memory.

Let us now consider whether justice requires the toleration of the intolerant, and if so under what conditions. There are a variety of situations in which this question arises. Some political parties in democratic states hold doctrines that commit them to suppress the constitutional liberties whenever they have the power. Again, there are those who reject intellectual freedom but who nevertheless hold positions in the university. It may appear that toleration in these cases is inconsistent with the principles of justice, or at any rate not required by them.

The greatness of the human being consists in this: that it is capable of the universe.

There are infinitely many variations of the initial situation and therefore no doubt indefinitely many theorems of moral geometry.

For the most trifling reasons, and sometimes for no conceivable reason at all, his majesty has rejected laws of the most salutary tendency. The abolition of domestic slavery is the great object of desire in those colonies where it was unhappily introduced in their infant state. But previous to the infranchisement of the slaves we have, it is necessary to exclude all further importations from Africa. Yet our repeated attempts to effect this by prohibitions, and by imposing duties which might amount to a prohibition, have been hitherto defeated by his majesty's negative: thus preferring the immediate advantages of a few British corsairs to the lasting interests of the American states, and to the rights of human nature deeply wounded by this infamous practice.

Whatever you do, crush the infamous thing, and love those who love you.

If thou wilt be perfect, go and sell that thou hast, and give to the poor, and thou shalt have treasure in heaven: and come and follow me.

God is imperiled. He is not almighty, that we may cross our hands, waiting for certain victory. He is not all-holy, that we may wait trustingly for him to pity and to save us. Within the province of our ephemeral flesh all of God is imperiled. He cannot be saved unless we save him with our own struggles; nor can we be saved unless he is saved. We are one. From the blind worm in the depths of the ocean to the endless arena of the Galaxy, only one person struggles and is imperiled: You. And within your small and earthen breast only one thing struggles and is imperiled: the Universe.

FREEDOM, the realization of freedom: who can deny that this is what today heads the agenda of history? ... Revolutionary propaganda is in its deepest sense the negation of the existing conditions of the State, for, with respect to its innermost nature, it has no other program than the destruction of whatever order prevails at the time.... We must not only act politically, but in our politics act religiously, religiously in the sense of freedom, of which the one true expression is justice and love. Indeed, for us alone, who are called the enemies of the Christian religion, for us alone it is reserved, and even made the highest duty ... really to exercise love, this highest commandment of Christ and this only way to true Christianity. 

The cultural treasures of the past, believed to be dead, are being made to speak, in the course of which it turns out that they propose things altogether different than what had been thought.

We are all such accidents. We do not make up history and culture. We simply appear, not by our own choice. We make what we can of our condition with the means available. We must accept the mixture as we find it - the impurity of it, the tragedy of it, the hope of it.

[L]ike Coleridge, he might plead as a set-off that he had been to many persons, through his conversation, a source not only of much instruction but of great elevation of character. On me his influence was most salutary. It was moral in the best sense. He took a sincere and kind interest in me, far beyond what could have been expected towards a mere youth from a man of his age, standing, and what seemed austerity of character. There was in his conversation and demeanour a tone of high-mindedness which did not show itself so much, if the quality existed as much, in any of the other persons with whom at that time I associated. My intercourse with him was the more beneficial, owing to his being of a different mental type from all other intellectual men whom I frequented...

Our minds are finite, and yet even in these circumstances of finitude we are surrounded by possibilities that are infinite, and the purpose of human life is to grasp as much as we can out of the infinitude.

By involving all men in all men, by the electric extension of their own nervous systems, the new technology turns the figure of the primitive society into a universal ground that buries all previous figures.

A little folly is desirable in him that will not be guilty of stupidity.

Besides, we should never attempt to balance anybody's misery against somebody else's happiness.

But of such writers the number is yet (and will I fear always be so) small, that I shall not need to make many exceptions, when I treat of the usefulness of writing books of essays, in comparison of that of writing systematically: or, at least... whilst I presume not to judge of other men's abilities, I hope it may be lawful for me to confess freely to you concerning myself, that I am very sensible of my being far from having such a stock of experiments and observations, as I judge requisite to write systematically; and I am apt to impute many of the deficiencies to be met with in the theories and reasonings of such great wits as Aristotle, Campanella, and some other celebrated philosophers, chiefly to this very thing, that they have too hastily, and either upon a few observations, or at least without a competent number of experiments, presumed to establish principles, and deliver axioms.

Even if I could by gradual degrees be transformed into a bat, nothing in my present constitution enables me to imagine what the experiences of such a future stage of myself thus metamorphosed would be like. The best evidence would come from the experience of bats, if we only knew what they were like.

A belief in hell and the knowledge that every ambition is doomed to frustration at the hands of a skeleton have never prevented the majority of human beings from behaving as though death were no more than an unfounded rumour, and survival a thing beyond the bounds of possibility.

It is necessary to show that there is nothing so little known [as the above rules], nothing more difficult to practice, or nothing more useful and universal.

Environment is process, not container.

Only optimists commit suicide, the optimists who can no longer be . . . optimists. The others, having no reason to live, why should they have any to die?

It is by logic that we prove, but by intuition that we discover. To know how to criticize is good, to know how to create is better.

The capitalist call workers to the factory, for example, directing them to collaborate and communicate in production and giving them the means to do so. In the paradigm of immaterial production, in contrast, labor itself tends to produce the means of interaction, communication, and cooperation for production directly. Affective labor always directly constructs a relationship.

An ethos of freedom stops power from solidifying into domination and makes sure it remains an open game.

There is no need for you to develop an armed insurrection. Christ himself has already begun an insurrection with his mouth.

God looks at the clean hands, not the full ones.

A man might say, with enough truth to justify a joke: "Science is what we know, and philosophy is what we don't know." But it should be added that philosophical speculation as to what we do not yet know has shown itself a valuable preliminary to exact scientific knowledge.

Man is to be found in reason, God in the passions.

The sense of justice and injustice is not deriv'd from nature, but arises artificially... from education, and human conventions.

In politics, love is a stranger, and when it intrudes upon it nothing is being achieved except hypocrisy. All the characteristics you stress in the Negro people: their beauty, their capacity for joy, their warmth, and their humanity, are well-known characteristics of all oppressed people. They grow out of suffering and they are the proudest possession of all pariahs. Unfortunately, they have never survived the hour of liberation by even five minutes. Hatred and love belong together, and they are both destructive; you can afford them only in private and, as a people, only so long as you are not free.

Animals only follow their natural instincts; but man, unless he has experienced the influence of learning and philosophy, is at the mercy of impulses that are worse than those of a wild beast. There is no beast more savage and dangerous than a human being who is swept along by the passions of ambition, greed, anger, envy, extravagance, and sensuality.

Do not then consider life a thing of any value. For look at the immensity of time behind thee, and to the time which is before thee, another boundless space. In this infinity then what is the difference between him who lives three days and him who lives three generations?

Death poses a problem which replaces all the others. What is deadly to philosophy, to the naive belief in the hierarchy of perplexities.

Taken as a whole, the Cross Correspondences and the Willet scripts are among the most convincing evidence that at present exists for life after death. For anyone who is prepared to devote weeks to studying them, they prove beyond all reasonable doubt that Myers, Gurney, and Sidgwick went on communicating after death.

And what has Don Quixote left, do you ask? I answer, he has left himself, and a man, a living and eternal man, is worth all the theories and all the philosophies. Other peoples have left chiefly institutions, books; we have left souls; St. Teresa is worth any institution, any Critique of Pure Reason.

See him, the newborn, dirty but marvelous, ridiculous in actuality, infinite in possibility, capable of that ultimate miracle, growth.

The smartphone seems to be a playground, but it is a digital panopticon.

A horse at the end of the race...A dog when the hunt is over...A bee with its honey stored...And a human being after helping others. They don't make a fuss about it. They just go on to something else, as the vine looks forward to bearing fruit again in season. We should be like that. Acting almost unconsciously.

We see that experience plays an indispensable role in the genesis of geometry; but it would be an error thence to conclude that geometry is, even in part, an experimental science. If it were experimental it would be only approximative and provisional. And what rough approximation!...The object of geometry is the study of a particular 'group'; but the general group concept pre-exists... in our minds. It is imposed on us, not as form of our sense, but as form of our understanding. Only, from among all the possible groups, that must be chosen... will be... the standard to which we shall refer natural phenomena.Experience guides us in this choice without forcing it upon us; it tells us not which is the truest geometry, but which is the most convenient.Notice that I have been able to describe the fantastic worlds... imagined without ceasing to employ the language of ordinary geometry.

Whenever you say anything good about East Germany, immediately somebody jumps up and says, "My God, you're a Stalinist..." I'm not defending everything about it, of course. But I laboured on the chapter that talks about the east. I fact-checked it; I had somebody else fact-check it. I knew that I was going to get a lot of flak for that. But in the beginning, East Germany did a better job. They just did.

The supreme task of the physicist is to arrive at those universal elementary laws from which the cosmos can be built up by pure deduction. There is no logical path to these laws; only intuition, resting on sympathetic understanding of experience, can reach them. In this methodological uncertainty, one might suppose that there were any number of possible systems of theoretical physics all equally well justified; and this opinion is no doubt correct, theoretically. But the development of physics has shown that at any given moment, out of all conceivable constructions, a single one has always proved itself decidedly superior to all the rest.

No man is exempt from saying silly things; the mischief is to say them deliberately.
