The struggle between the opponents and defenders of capitalism is a struggle between innovators who do not know what innovation to make and conservatives who do not know what to conserve.

The materialists say, it is by means of a series of straight lines more or less perfect that one imagines the perfect straight line as an ideal limit. That is right, but the progression in itself necessarily contains what is infinite; it is in relation to the perfect straight line that one can say that such and such a straight line is less twisted than some other. ... Either one conceives the infinite or one does not conceive at all.

Stars and blossoming fruit-trees: utter permanence and extreme fragility give an equal sense of eternity.

There is a certain kind of morality which is even more alien to good and evil than amorality is.

Every time that a man has, with a pure heart, called upon Osiris, Dionysus, Buddha, the Tao, etc., the Son of God has answered him by sending the Holy Spirit. And the Holy Spirit has acted upon his soul, not by inciting him to abandon his religious tradition, but by bestowing upon him light - and in the best of cases the fullness of light - in the heart of that same religious tradition. ... It is, therefore, useless to send out missions to prevail upon the peoples of Asia, Africa or Oceania to enter the Church.

If we love God while thinking that he does not exist, he will manifest his existence.

When, as a result of what was called Enlightenment in the eighteenth century, the priests had in fact almost entirely lost this function of guidance. Their place was taken by writers and scientists. In both cases it is equally absurd. Mathematics, physics, and biology are as remote from spiritual guidance as the art of arranging words. When that function is usurped by literature and science it proves there is no longer any spiritual life.

Above all our thought should be empty, waiting, not seeking anything, but ready to receive in its naked truth the object that is to penetrate it. All wrong translations, all absurdities in geometry problems, all clumsiness of style, and all faulty connection of ideas in compositions and essays, all such things are due to the fact that thought has seized upon some idea too hastily, and being thus prematurely blocked, is not open to the truth.

The necessity for power is obvious, because life cannot be lived without order; but the allocation of power is arbitrary because all men are alike, or very nearly. Yet power must not seem to be arbitrarily allocated, because it will not then be recognized as power. Therefore prestige, which is illusion, is of the very essence of power.

The first thing that we know about ourselves is our imperfection.

The most important part of education - to teach the meaning of to know (in the scientific sense). The last statement in her notebook

Truth is sought not because it is truth but because it is good.

Besides, it is written that the tree shall be known by its fruits. The Church has borne too many evil fruits for there not to have been some mistake at the beginning. Europe has been spiritually uprooted, cut off from that antiquity in which all the elements of our civilization have their origin; and she has gone about uprooting the other continents from the sixteenth century onwards. Missionary zeal has not Christianized Africa, Asia and Oceania, but has brought these territories under the cold, cruel and destructive domination of the white race, which has trodden down everything. It would be strange, indeed, that the word of Christ should have produced such results if it had been properly understood.

If we want a love which will protect the soul from wounds we must love something other than God.

It is not only in literature that fiction generates immorality. It does it also in life itself. For the substance of our life is almost exclusively composed of fiction. We fictionalize our future, and, unless we are heroically devoted to truth, we fictionalize our past, refashioning it to our taste. We do not study other people; we invent what they are thinking, saying, and doing. Reality provides us with some raw material, just as novelists often take a theme from a news item, but we envelop it in a fog in which, as in all fiction, values are reversed, so that evil is attractive and good is tedious.

We do not obtain the most precious gifts by going in search of them but by waiting for them. Man cannot discover them by his own powers, and if he sets out to seek for them he will find in their place counterfeits of which he will be unable to discern falsity.

An imaginary perfection is automatically at the same level as I who imagine it - neither higher nor lower.

My purpose here is to denounce an idea which seems to be dangerous and false. ... Revolutionary trade unionists and orthodox communists are at one in considering everything that is purely theoretical as bourgeois. ... The culture of a socialist society would be a synthesis of theory and practice; but to synthesize is not the same as to confuse together; it is only contraries that can be synthesized. ... Marx's principal glory is to have rescued the study of societies not only from Utopianism but also and at the same time from empiricism. ... Humanity cannot progress by importing into theoretical study the processes of blind routine and haphazard experiment by which production has so long been dominated. ... The true relation between theory and application only appears when theoretical research has been purged of all empiricism.

Humility consists of knowing that in this world the whole soul, not only what we term the ego in its totality, but also the supernatural part of the soul, which is God present in it, is subject to time and to the vicissitudes of change. There must be absolutely acceptance of the possibility that everything material in us should be destroyed. But we must simultaneously accept and repudiate the possibility that the supernatural part of the soul should disappear.

We can know only one thing about God - that he is what we are not. Our wretchedness alone is an image of this. The more we contemplate it, the more we contemplate him.

One could count on one's fingers the number of scientists in the entire world who have a general idea of the history and development of their own particular science; there is not one who is really competent as regards sciences other than his own. As science forms an indivisible whole, one may say that there are no longer, strictly speaking, any scientists, but only drudges doing scientific work. . . .

God's love for us is not the reason for which we should love him. God's love for us is the reason for us to love ourselves.

The essential characteristic of the first half of the twentieth century is the growing weakness, and almost the disappearance, of the idea of value.

The capacity to give one's attention to a sufferer is a very rare and difficult thing; it is almost a miracle; it is a miracle. Nearly all those who think they have this capacity do not possess it. Warmth of heart, impulsiveness, pity are not enough.

It is not in a person's nature to desire what he already has. Desire is a tendency, the start of a movement toward something, toward a point from which one is absent. If, at the very outset, this movement doubles back on itself toward its point of departure, a person turns round and round like a squirrel in a cage or a prisoner in a condemned cell. Constant turning soon produces revulsion. All workers, especially though not exclusively those who work under inhumane conditions, are easily the victims of revulsion, exhaustion and disgust and the strongest are often the worst affected.

Respectable scientists like de Broglie himself accept wave mechanics because it confers coherence and unity upon the experimental findings of contemporary science, and in spite of the astonishing changes it implies in connection with ideas of causality, time, and space, but it is because of these changes that it wins favor with the public. The great popular success of Einstein was the same thing. The public drinks in and swallows eagerly everything that tends to dispossess the intelligence in favor of some technique; it can hardly wait to abdicate from intelligence and reason and from everything that makes man responsible for his destiny.

The key to a Christian conception of studies is the realization that prayer consists of attention. It is the orientation of all the attention of which the soul is capable toward God. The quality of the attention counts for much in the quality of the prayer. Warmth of heart cannot make up for it.

The recognition of human wretchedness is difficult for whoever is rich and powerful because he is almost invincibly led to believe that he is something. It is equally difficult for the man in miserable circumstances because he is almost invincibly led to believe that the rich and powerful man is something.

I too have a growing inner certainty that there is a deposit of pure gold in me which ought to be passed on. The trouble is that I am more and more convinced by my experience and observation of my contemporaries that there is no one to receive it.

To desire friendship is a great fault. Friendship should be a gratuitous joy like those afforded by art or life. We must refuse it so that we may be worthy to receive it; it is of the order of grace.

Dadaism and surrealism ... represented the intoxication of total license, the intoxication in which the mind wallows when it has made a clean sweep of value and surrendered to the immediate. The good is the pole towards which the human spirit is necessarily oriented, not only in action but in every effort, including the effort of pure intelligence. The surrealists have set up non-oriented thought as a model; they have chosen the total absence of value as their supreme value. Men have always been intoxicated by license, which is why, throughout history, towns have been sacked. But there has not always been a literary equivalent for the sacking of towns. Surrealism is such an equivalent.

Whenever one tries to suppress doubt, there is tyranny.

If people were told: what makes carnal desire imperious in you is not its pure carnal element. It is the fact that you put into it the essential part of yourself-the need for Unity, the need for God - they wouldn't believe it. To them it seems obvious that the quality of imperious need belongs to the carnal desire as such. In the same way it seems obvious to the miser that the quality of desirability belongs to gold as such, and not to its exchange value.

He who does not realize to what extent shifting fortune and necessity hold in subjection every human spirit, cannot regard as fellow-creatures nor love as he loves himself those whom chance separated from him by an abyss. The variety of constraints pressing upon man give rise to the illusion of several distinct species that cannot communicate.

The human soul has need of truth and of freedom of expression. The need for truth requires that intellectual culture should be universally accessible, and that it should be able to be acquired in an environment neither physically remote nor psychologically alien.

It is because of my wretchedness that I am "I." It is on account of the wretchedness of the universe that, in a sense, God is "I" (that is to say a person).

Attention is the rarest and purest form of generosity.

We must wish either for that which actually exists or for that which cannot in any way exist - or, still better, for both. That which is and that which cannot be are both outside the realm of becoming.

Might is that which makes a thing of anybody who comes under its sway. When exercised to the full, it makes a thing of man in the most literal sense, for it makes him a corpse.

If anyone possesses this faculty, then his attention is in reality directed beyond the world, whether he is aware of it or not. The link which attaches the human being to the reality outside the world is, like the reality itself, beyond the reach of human faculties. The respect that it makes us feel as soon as it is recognized cannot be shown to us by evidence or testimony.

The notion of rights is linked with the notion of sharing out, of exchange, of measured quantity. It has a commercial flavor, essentially evocative of legal claims and arguments. Rights are always asserted in a tone of contention; and when this tone is adopted, it must rely upon force in the background, or else it will be laughed at.

The simultaneous existence of opposite virtues in the soul - like pincers to catch hold of God.

Conscience is deceived by the social. Our supplementary energy (imaginative) is to a great extent taken up with the social. It has to be detached from it. That is the most difficult of detachments.

There are two atheisms of which one is a purification of the notion of God.

The eulogies of my intelligence are positively intended to evade the question "Is what she says true?"

Only he who has measured the dominion of force, and knows how not to respect it, is capable of love and justice.

In order to be exercised, the intelligence requires to be free to express itself without control by any authority. There must therefore be a domain of pure intellectual research, separate but accessible to all, where no authority intervenes. The human soul has need of some solitude and privacy and also of some social life.The human soul has need of both personal property and collective property.

Those who keep the masses of men in subjection by exercising force and cruelty deprive them at once of two vital foods, liberty and obedience; for it is no longer within the power of such masses to accord their inner consent to the authority to which they are subjected. Those who encourage a state of things in which the hope of gain is the principal motive take away from men their obedience, for consent which is its essence is not something which can be sold.

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.

It is not religion but revolution which is the opium of the people.
