Diversity makes critical argument fruitful. ...[P]artners in an argument must share ...the wish to know, and the readiness to learn from the other ...by severely criticizing his views... and hearing... [the] reply. ...the so-called method of science consists in this kind of criticism.

Concern for the symbol has completely disappeared from our science. And yet, if one were to give oneself the trouble, one could easily find, in certain parts at least of contemporary mathematics... symbols as clear, as beautiful, and as full of spiritual meaning as that of the circle and mediation. From modern thought to ancient wisdom the path would be short and direct, if one cared to take it.

Do not yet see, that, if the single man plant himself indomitably on his instincts, and there abide, the huge world will come round to him.

Again and again our foe, religion, has given birth to deeds sinful and unholy.

The heart of Christianity is a myth which is also a fact.

Death induces the sensual person to say: Let us eat and drink, because tomorrow we shall die – but this is sensuality's cowardly lust for life, that contemptible order of things where one lives in order to eat and drink instead of eating and drinking in order to live.

The fact that labour is external to the worker, i.e., it does not belong to his intrinsic nature; that in his work, therefore he does not affirm himself but denies himself, does not feel content but unhappy, does not develop freely his physical and mental energy but mortifies his body and his mind. The worker therefore only feels himself outside his work, and in his work feels outside himself.

I do not know, my listener, what your crime, your guilt, your sins are, but surely we are all more or less of the guilt of loving only little. Take comfort, then, in these words just as I take comfort in them.

For me any of the little gestures I make are all tentative probes. That's why I feel free to make them sound as outrageous or extreme as possible. Until you make it extreme, the probe is not very efficient.

The next thing you can learn from the woman who was a sinner, something she herself understood, is that with regard to finding forgiveness she is able to do nothing at all.

What is obscene about pornography is not an excess of sex, but the fact that it contains no sex at all.

In his Experiment in Autobiography (1934), H.G. Wells pointed out that ever since the beginning of life, most creatures have been 'up against it'. Their lives are a drama of struggle against the forces of nature. Yet nowadays you can say to a man: Yes, you earn a living, you support a family, you love and hate, but -- what do you do? His real interest may be in something else -- art, science, literature, philosophy. The bird is a creature of the air, the fish is a creature of the water, and man is a creature of the mind.

Buddhism ... is not a culture but a critique of culture, an enduring nonviolent revolution or "loyal opposition" to the culture in which it is involved.

What we principally thought of, was to alter people's opinions; to make them believe according to evidence, and know what was their real interest, which when they once knew, they would, we thought, by the instrument of opinion, enforce a regard to it upon one another. While fully recognizing the superior excellence of unselfish benevolence and love of justice, we did not expect the regeneration of mankind from any direct action on those sentiments, but from the effect of educated intellect, enlightening the selfish feelings. Although this last is prodigiously important as a means of improvement in the hands of those who are themselves impelled by nobler principles of action, I do not believe that any one of the survivors of the Benthamites or Utilitarians of that day, now relies mainly upon it for the general amendment of human conduct.

The trade of insurance gives great security to the fortunes of private people, and by dividing among a great many that loss which would ruin an individual, makes it fall light and easy upon the whole society.

Gentleness, as opposed to an irascible temper, greatly contributes to the tranquility and happiness of life, by preserving the mind from perturbation, and arming it against the assaults of calumny and malice.

Abstain from animals.

Even when the wound is healed, the scar remains.

Neither a man nor a crowd nor a nation can be trusted to act humanely or to think sanely under the influence of a great fear.

Some would deny any legitimate use of the word God because it has been misused so much. Certainly it is the most burdened of all human words. Precisely for that reason it is the most imperishable and unavoidable. And how much weight has all erroneous talk about God's nature and works (although there never has been nor can be any such talk that is not erroneous) compared with the one truth that all men who have addressed God really meant him? For whoever pronounces the word God and really means Thou, addresses, no matter what his delusion, the true Thou of his life that cannot be restricted by any other and to whom he stands in a relationship that includes all others.

To kill someone for committing murder is a punishment incomparably worse than the crime itself. Murder by legal sentence is immeasurably more terrible than murder by brigands.

But though empires, like all the other works of men, have all hitherto proved mortal, yet every empire aims at immortality.

Put up again thy sword into his place: for all they that take the sword shall perish with the sword. Thinkest thou that I cannot now pray to my Father, and he shall presently give me more than twelve legions of angels? But how then shall the scriptures be fulfilled, that thus it must be?

Deconstruction never had meaning or interest, at least in my eyes, than as a radicalization, that is to say, also within the tradition of a certain Marxism, in a certain spirit of Marxism.

Hegel once observed that comedy is in act superior to tragedy and humourous reasoning superior to grandiloquent reasoning. Although Lincoln does not possess the grandiloquence of historical action, as an average man of the people he has its humour.

Make your educational laws strict and your criminal ones can be gentle; but if you leave youth its liberty you will have to dig dungeons for ages.

But what then is this confrontation below the language of reason? Where might this interrogation lead, following not reason in its horizontal becoming, but seeking to retrace in time this constant verticality, which, the length of Western culture, confronts it with what it is not, measuring it with its own extravagance?

Self-conscious rejection of the absolute is the best way to resist God; thus illusion, the substance of life, is saved.

The Book had in a high degree excited us to self-activity, which is the best effect of any book.

In plain truth, lying is an accursed vice. We are not men, nor have any other tie upon another, but by our word.

Books ... hold within them the gathered wisdom of humanity, the collected knowledge of the world's thinkers, the amusement and excitement built up by the imaginations of brilliant people. Books contain humor, beauty, wit, emotion, thought, and, indeed, all of life. Life without books is empty.

Even the most wretched individual of our present society could not exist and develop without the cumulative social efforts of countless generations. Thus the individual, his freedom and reason, are the products of society, and not vice versa: society is not the product of individuals comprising it; and the higher, the more fully the individual is developed, the greater his freedom - and the more he is the product of society, the more does he receive from society and the greater his debt to it.

The first remark we have to make, and which - though already presented more than once - cannot be too often repeated when the occasion seems to call for it, - is that what we call principle, aim, destiny, or the nature and idea of Spirit, is something merely general and abstract. Principle - Plan of Existence - Law - is a hidden, undeveloped essence, which as such - however true in itself - is not completely real.

Religion is, as it were, the calm bottom of the sea at its deepest point, which remains calm however high the waves on the surface may be.

The first thinker was, without a doubt, the first man obsessed by why. An unaccustomed mania, not at all contagious: rare indeed are those who suffer from it, who are a prey to questioning, and who can accept no given because they were born in consternation.

He who lives as children live who does not struggle for his bread and does not believe that his actions possess any ultimate significance remains childlike.

And surely to know what this good is, is of great importance for the conduct of life, for in that case we shall be like archers shooting at a definite mark, and shall be more likely to do what is right. But, if this is the case, we must try to comprehend, in outline at least, what it is and to which of the sciences it belongs.

Deception, flattering, lying, deluding, talking behind the back, putting up a false front, living in borrowed splendor, wearing a mask, hiding behind convention, playing a role for others and for oneself, in short, a continuous fluttering around the solitary flame of vanity is so much the rule and the law among men that there is almost nothing which is less comprehensible than how an honest and pure drive for truth could have arisen among them. They are deeply immersed in illusions and in dream images; their eyes merely glide over the surface of things and see "forms." Variant translation: The constant fluttering around the single flame of vanity is so much the rule and the law that almost nothing is more incomprehensible than how an honest and pure urge for truth could make its appearance among men.

Common sense doesn't have the last word in ethics or anywhere else, but it has, as J. L. Austin said about language, the first word: it should be examined before it is discarded.

If life is deprived of any meaningful closure, it will be ended in non-time.

Good order is the foundation of all good things.

Artistic creation is a demand for unity and a rejection of the world.

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.

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

If man of himself could in a perfect manner know all things visible and invisible, it would indeed be foolish to believe what he does not see. But our manner of knowing is so weak that no philosopher could perfectly investigate the nature of even one little fly.

To be old is a glorious thing when one has not unlearned what it means to begin, this old man had perhaps first learned it thoroughly in old age.

The frontiers are not east or west, north or south, but wherever a man fronts a fact, though that fact be his neighbor, there is an unsettled wilderness between him and Canada, between him and the setting sun, or, farther still, between him and it.
