If there is anyone who owes everything to Bach, it is certainly God.

Our life is no dream, but it should and perhaps will become one.

What has to be accepted, the given, is - so one could say - forms of life.

Cultural dominance by either the left or the right hemisphere is largely dependent upon environmental factors.

I have no faith in precision: ...simplicity and clarity are values in themselves, but not... [of] precision or exactness...

A grievous crime indeed against religion has been committed by the man who imagines that Islam is defended by the denial of the mathematical sciences.

No particular experiences are linked with any particular statements in the interior of the field, except indirectly through considerations of equilibrium affecting the field as a whole.

It is then unnecessary to investigate whether there be beyond the heaven Space, Void or Time. For there is a single general space, a single vast immensity which we may freely call Void; in it are innumerable globes like this one on which we live and grow. This space we declare to be infinite, since neither reason, convenience, possibility, sense-perception nor nature assign to it a limit. In it are an infinity of worlds of the same kind as our own.

All the great speakers were bad speakers at first.

We ought to regard the interests of the state as of far greater moment than all else, in order that they may be administered well; and we ought not to engage in eager rivalry in despite of equity, nor arrogate to ourselves any power contrary to the common welfare. For a state well administered is our greatest safeguard. In this all is summed up: When the state is in a healthy condition all things prosper; when it is corrupt, all things go to ruin.

Reason is immortal, all else mortal.

Sartre observed that he had never felt so free as during the German occupation when (as a member of the French resistance) he was in constant danger of being arrested and shot. Could there be a more conclusive proof that human beings are freer than they realize, and that their freedom is eroded by habit and laziness?

This life is worth living, we can say, since it is what we make it, from the moral point of view.

Inspect every piece of pseudoscience and you will find a security blanket, a thumb to suck, a skirt to hold. What does the scientist have to offer in exchange? Uncertainty! Insecurity!

Morality is the beauty of Philosophy.

Men are at variance with the one thing with which they are in the most unbroken communion, the reason that administers the whole universe.

Any loss of identity prompts people to seek reassurance and rediscovery of themselves by testing, and even by violence. Today, the electric revolution, the wired planet, and the information environment involve everybody in everybody to the point of individual extinction.

It cannot be sufficiently emphasized that revolution is in vain unless inspired by its ultimate ideal. Revolutionary methods must be in tune with revolutionary aims. The means used to further the revolution must harmonize with its purposes. In short, the ethical values which the revolution is to establish in the new society must be initiated with the revolutionary activities of the so-called transitional period. The latter can serve as a real and dependable bridge to the better life only if built of the same material as the life to be achieved.

The imagination is not a talent of some men but is the health of every man.

In the general tendency toward specialization, philosophy too has established itself as a specialized discipline, one purified of all specific content. In so doing, philosophy has denied its own constitutive concept: the intellectual freedom that does not obey the dictates of specialized knowledge.

By a lie a man throws away and, as it were, annihilates his dignity as a man. A man who himself does not believe what he tells another ... has even less worth than if he were a mere thing. ... makes himself a mere deceptive appearance of man, not man himself.

Science can only be comprehended epistemologically, which means as one category of possible knowledge, as long as knowledge is not equated either effusively with the absolute knowledge of a great philosophy or blindly with scientistic self-understanding of the actual business of research.

Those who read and rightly understand my teaching will not start an insurrection; they have not learned that from me.

It might be plausibly maintained, that in almost every one of the leading controversies, past or present, in social philosophy, both sides were in the right in what they affirmed, though wrong in what they denied.

When scientists take part in activity they transform themselves from scientists into acting beings, that is, they become elements, data, facts; as soon as they reflect on their activity, however, they are re-transformed into scientists. The trained specialist qua scientist looks upon himself as a chain of judgments and inferences; qua member of society, he regard himself as a mere object. The same holds for everyone. The individual is divided into innumerable functions, the interconnection of which are unknown. In society a man is pater familias under one aspect, business man under another, thinker under a third; to be more precise, he is not a human being at all, but all these aspects and many more in an inevitable succession.

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

What terrible tragedies realism inflicts on people.'

Genius borrows nobly. When Shakespeare is charged with debts to his authors, Landor replies: "Yet he was more original than his originals. He breathed upon dead bodies and brought them into life."

In America, more than anywhere else in the world, care has been taken constantly to trace clearly distinct spheres of action for the two sexes, and both are required to keep in step, but along paths that are never the same.

By reducing any quality to quantity, myth economizes intelligence: it understands reality more cheaply.

Art is anything you can get away with.

Modesty is an unnatural attitude, and one which is only with difficulty taught to children.

Disbelieve nothing wonderful concerning the gods, nor concerning divine dogmas.

We are so lonely in life that we must ask ourselves if the loneliness of dying is not a symbol of our human existence.

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.

Animals are born and bred in litters. Solitude grows blessed and peaceful only in old age.

Secrets in manufactures are capable of being longer kept than secrets in trade.

The same law that shapes the earth-star shapes the snow-star. As surely as the petals of a flower are fixed, each of these countless snow-stars comes whirling to earth...these glorious spangles, the sweeping of heaven's floor.

Some philosophers fail to distinguish propositions from judgments; ... But in the real world it is more important that a proposition be interesting than that it be true. The importance of truth is that it adds to interest.

In this initial illimitableness of possibilities that characterizes one who has no nature there stands out only one fixed, pre-established, and given line by which he may chart his course, only one limit: the past.

We regret not having the courage to make such and such decision; we regret much more having made one - any one. Better no action than the consequences of an action.

The single spirit doth simultaneously temper the whole together; this is the single soul of all things; all are filled with God.

Do you see this egg? With this you can topple every theological theory, every church or temple in the world. What is it, this egg, before the seed is introduced into it? An insentient mass. And after the seed has been introduced to into it? What is it then? An insentient mass. For what is the seed itself other than a crude and inanimate fluid? How is this mass to make a transition to a different structure, to sentience, to life? Through heat. And what will produce that heat in it? Motion. "Conversation Between D'Alembert and Diderot", as quoted in Selected Writings (1966) edited by Lester G. Crocker, and The Enlightenment and the Intellectual Foundations of Modern Culture (2004) by Louis K Dupré, p. 30 Variant translation: See this egg. It is with this that all the schools of theology and all the temples of the earth are to be overturned.

As soon as it is held that any belief, no matter what, is important for some other reason than that it is true, a whole host of evils is ready to spring up. Discouragement of inquiry, ... is the first of these, but others are pretty sure to follow. Positions of authority will be open to the orthodox. Historical records must be falsified if they throw doubt on received opinion. Sooner or later unorthodoxy will come to be considered a crime to be dealt with by the stake, the purge, or the concentration camp. I can respect the men who argue that religion is true and therefore ought to be believed, but I can only feel profound moral reprobation for those who say that religion ought to be believed because it is useful, and that to ask whether it is true is a waste of time.

The extent of the region of the uncertain, the number of the problems the investigation of which ends in a verdict of not proven, will vary according to the knowledge and the intellectual habits of the individual agnostic. I do not very much care to speak of anything as unknowable. What I am sure about is that there are many topics about which I know nothing, and which, so far as I can see, are out of reach of my faculties. But whether these things are knowable by any one else is exactly one of those matters which is beyond my knowledge, though I may have a tolerably strong opinion as to the probabilities of the case.

The Interpretation of the Laws of Nature in a Common-wealth, dependeth not on the books of Moral Philosophy. The Authority of writers, without the Authority of the Commonwealth, maketh not their opinions Law, be they never so true.

As to riots and tumults, let those answer for them, who, by willful misrepresentations, endeavor to excite and promote them; or who seek to stun the sense of the nation, and to lose the great cause of public good in the outrages of a misinformed mob. We take our ground on principles that require no such riotous aid. We have nothing to apprehend from the poor; for we are pleading their cause. And we fear not proud oppression, for we have truth on our side.

No sacrifice is lost for a great ideal!

In former times the chief method of justifying the use of violence and thereby infringing the law of love was by claiming a divine right for the rulers: the Tsars, Sultans, Rajahs, Shahs, and other heads of states. But the longer humanity lived the weaker grew the belief in this peculiar, God-given right of the ruler. That belief withered in the same way and almost simultaneously in the Christian and the Brahman world, as well as in Buddhist and Confucian spheres, and in recent times it has so faded away as to prevail no longer against man's reasonable understanding and the true religious feeling. People saw more and more clearly, and now the majority see quite clearly, the senselessness and immorality of subordinating their wills to those of other people just like themselves, when they are bidden to do what is contrary not only to their interests but also to their moral sense.

What most clearly characterizes true freedom and its true employment is its misemployment.
