"Aspen tree, your leaves glance white into the dark."
"We stand by the window embracing, and people look up from the street: it is time they knew! It is time the stone made an effort to flower, time unrest had a beating heart. It is time it were time.It is time."
"In principle, should the laborers have the produce of their labor? I do not hesitate to say: No! although I know that a multitude of workers will cry out. Look, proletarians, cry out, shout as much as you like, but then listen to me: No, it is not the product of their labors to which the workers have a right. It is the satisfaction of their needs, whatever the nature of those needs. To have the possession of the product of our labor is not to have possession of that which is proper to us, it is to have property in a product made by our hands, and which could be proper to others and not to us. And isn’t all property theft?"
"[T]he intellectual changes of Louis XIV's reign touch the history of science—especially as they represent the extension of the scientific method into other realms of thought. ...we meet the beginnings of the criticism of the French monarchy... acute criticism from... the French intelligentsia who could claim to understand the... state better than the king himself. ...The funeral orations of Fontenelle call attention to an aspect of this movement... [i.e.,] the initial effect of the new scientific movement on political thought. ...The first result ...as Fontenelle makes clear, was the insistence that politics requires the inductive method, the collection of information, the accumulation of concrete data and statistics. ...He describes ...how Vauban... travelled over France, accumulating data, seeing the condition[s]... for himself, studying commerce and the possibilities of commerce... gaining a knowledge of local conditions. Vauban, says Fontenelle, did more than anybody else to call mathematics out of the skies... [he] put statistics to the service of modern political economy and first applied the rational and experimental method in matters of finance. ...Fontenelle tells us that ...Sir , the author of Political Arithmetic, showed how much of the knowledge requisite for government reduces itself to mathematical calculation."
"Fontenelle provides an example of the transfer of the scientific spirit, and the application of methodical doubt, in... the History of Oracles. In a sense he is one of the predursors of the comparative method in the history of religion—the collection of myths of all lands to throw light on the development of human reason. ...he recommends the study of primitive tribes in our own day ...He treats myths as... a natural product, subject to scientific analysis—not the fruits of conscious imposture but the characteristic of a certain stage in human development. The human mind he regards as... the same in all times and ages, but subject to local influences... Here is a self-conscious attempt to show how the scientific method could receive extended application and could be transferred from the examination of purely material phenomena even into... human studies."
"His wit, his Learning, his Knowledge of Mankind, his exquisite Taste in all that is Polite, the Fire of his Imagination, the uncommon Felicity of his Eloquence, and the ready Turn of his Expression, are Reasons which the Publick will think very natural to direct me in this Address to Your Lordship."
"So that at length the Priests of Delphos being quite baffled with the railleries of those learned Wits, renounced all Verses, at least as to the speaking them from the Tripos; for there were still some Poets maintain'd in the Temple, who at leisure turned into Verse, what the Divine fury had inspired the Pythian Priestess withal in Prose. It was very pretty, that Men could not be contented to take the Oracle just as it came piping hot from the Mouth of their God. But perhaps, when they had come a great way for it, they thought it would look silly to carry home an Oracle in Prose."
"[A]bout the time of Alexander the Great, a little before Pyrrhus's days, there appear'd in Greece certain great Sects of Philosophers, such as the Peripateticks and Epicureans, who made a mock of Oracles. The Epicureans especially made sport with the paltry Poetry that came from Delphos. For the Priests hammered out their Verses as well as they could, and they often times committed faults against the common Rules of Prosodia. Now those Fleering Philosophers were mightily concerned that Apollo, the very God of Poetry, should come so far behind Homer, who was but a meer mortal, and was beholding to the same Apollo for his inspirations."
"It was to little purpose to excuse the matter, by saying, that the badness of the Verses was a kind of Testimony that they were made by a God, who nobly scorn'd to be tyed up to rules and to be confined to the Beauty of a Style. For this made no impression upon the Philosophers; who, to turn this answer into ridicule, compared it to the Story of a Painter, who being hired to draw the Picture of a Horse tumbling on his Back upon the ground, drew one running full speed: and when he was told, that this was not such a Picture as was bespoke, he turned it upside down, and then ask'd if the Horse did not tumble upon his back now. Thus these Philosophers jeered such Persons, who by a way of arguing that would serve both ways, could equally prove that the Verses were made by a God, whether they were good or bad."
"Men are not willing to suffer the decision of things to be too easie, and therefore they mingle their own prejudices with truths, and so create greater perplexities than are Naturally found therein; and those scruples, which our selves frame, give us the most pain to untangle."
"A mere nothing, a tiny fibre, something that could never be found by the most delicate anatomy, would have made of Erasmus and Fontenelle two idiots, and Fontenelle himself speaks of this very fact in one of his best dialogues."
"Behold a universe so immense that I am lost in it. I no longer know where I am. I am just nothing at all. Our world is terrifying in its insignificance."
"The calculus is to mathematics no more than what experiment is to physics, and all the truths produced solely by the calculus can be treated as truths of experiment. The sciences must proceed to first causes, above all mathematics where one cannot assume, as in physics, principles that are unknown to us. For there is in mathematics, so to speak, only what we have placed there... If, however, mathematics always has some essential obscurity that one cannot dissipate, it will lie, uniquely, I think, in the direction of the infinite; it is in that direction that mathematics touches on physics, on the innermost nature of bodies about which we know little."
"The geometrical spirit is not so tied to geometry that it cannot be detached from it and transported to other branches of knowledge. A work of morals or politics or criticism, perhaps even of eloquence, would be better (other things being equal) if it were done in the style of a geometer. The order, clarity, precision and exactitude which have been apparent in good books for some time might well have their source in this geometric spirit. ...Sometimes one great man gives the tone to a whole century; Descartes], to whom one might legitimately be accorded the glory of having established a new art of reasoning, was an excellent geometer."
"At the time the book of Marquis de l'Hôpital had appeared, and almost all mathematicians began to turn to the new geometry of the infinite [that is, the new infinitesimal calculus], until then little known. The surprising universality of the methods, the elegant brevity of the proofs, the neatness and speed of the most difficult solutions, a singular and unexpected novelty, all attracted the mind and there was in the mathematical world a well marked revolution [une révolution bien marquée."
"It is more reasonable to remove error from truth, than to venerate error because it is mix'd with truth."
"We can never add more truth to what is true already, nor make that true which is false."
"But why then did the Ancient Priestesses always answer in Verse? ...To this Plutarch replies... That even the Ancient Priestesses did now and then speak in Prose. And besides this, in Old times all People were born Poets. ...[T]hey had no sooner drank a little freely, but they made Verses; they had no sooner cast their eyes on a Handsom Woman, but they were all Poesy, and their very common discourse fell naturally into Feet and Rhime: So that their Feasts and their Courtships were the most delectable things in the World. But now this Poetick Genius has deserted Mankind: and tho' our passions be as ardent... yet Love at present creeps in humble prose. ...Plutarch gives us another reason ...that the Ancients wrote always in Verse, whether they treated of Religion, Morality, Natural Philosophy or Astrology. Orpheus and Hesiod, whom every body acknowledges for Poets, were Philosophers also: and Parmenides, Xenophanes, Empedocles, Eudoxus, and Thales... [the] Philosophers, were Poets too. It is very strange indeed that Poetry should be elder Brother to Prose... but it is very probable... precepts... were shap'd into measured lines, that they might be the more easily remembred: and therefore all their Laws and their rules of Morality were in Verse. By this we may see that Poetry had a much more serious beginning than is usually imagin'd, and that the Muses have of late days mightily deviated from their original Gravity."
"Now, the Priests who belonged to the Temples, scorn'd to use the same Customs in common with these Gypsies; for they thought themselves to be a nobler and graver sort of Fortune-tellers; which makes a mighty difference, I'll assure you, in this great affair."
"Cubism was born."
"We could not do it in the way he meant. But from the Rue Lamarck to the Rue Ravignan, the attempt [prétention] to imitate an orb on a vertical plane, or to indicate by a horizontal straight line the circular hole of a vase placed at the height of the eyes was considered as the artifice of an illusionistic trickery that belonged to another age."
"Instead of copying Nature, we [ Cubists ] create a 'milieu', of our own, wherein our sentiment can work itself out through a juxtaposition of colors. It is hard to explain it, but it may perhaps be illustrated by analogy of literature and music. Your [ Gelett Burgess is American] Edgar Poe did not attempt to reproduce Nature realistically. Some phase of life suggested an emotion, as that of horror in 'The Fall of the House of Ushur'. That subjective idea he translated into art. He made a composition of it."
"So, music does not attempt to imitate Nature's sounds, but it does interpet and embody emotions awakened by Nature through a convention of its own, in a way to be aesthetically pleasing. In some such way, we, taking our hint from Nature, construct decoratively pleasing harmonies and symphonies of color expression of our sentiments."
"Already, a conscious courage is coming to life. Here are some of the painters: Picasso, Georges Braque, Delaunay, Le Fauconnier.. ..they are highly enlightened, and do not believe in the stability of any system, even if it were to call itself classical art.. ..Their reason is poised between the pursuit of the fleeting and a mania for the eternal."
"We could not think of going back to the symbolic measures of the ancients and the primitives. Such cheap magician's tricks did not appeal to us."
"In fact it is a stupidity, Maurice Princet told me in the presence of Juan Gris, to claim to be able to bring together in a single system of relations, colour, which is a sensation that only needs to be received, and form which is an organisation that has to be understood (14); and, introducing us to the non-Euclidean geometries, he urged us to create a geometry for painters."
"Whether it is Juan Gris taking objects apart, Picasso replacing them with objects of his own invention, or another who replaces conical perspective by a system based on the relations between perpendiculars, all that only goes to show that Cubism was not at all born out of an authoritative theory [mot d'ordre]; that it only marked among a few painters the will to be finished with an art that never ought to have survived the condemnation pronounced upon it by Pascal."
""What madman, or what clever-dick with the instincts of a counterfeiter was the first to paint a sphere in trompe l'oeil on a surface that is vertical and rigorously flat! And that's what they teach at the Beaux-Arts [academy]! How could such idiocies ever have survived the verdict of Pascal?" [quote of Albert Gleizes ]. That was how, in 1906, Albert Gleizes was feeling his way towards Cubism and condemned in advance those who never saw anything in it other than a shibboleth [mot d'ordre]. It was still nothing more than a need he felt, the need not for an intellectual art but for an art that would be something other than a systematic absurdity. Quite clearly nature and the painting make up two different worlds which have nothing in common, and what is quite in its place in the one cannot also be in its place in the other."
"Albert Gleizes did not know Montmartre, had never seen anything of Picasso or Juan Gris, never heard Maurice Princet construct an infinite number of different spaces for the use of painters, but he described to me the absurdity of the museums in which mournful, extravagantly three dimensional crowds threaten to crush the visitor by jumping out of their frames."
"The excuse that the painters were documenting reality was becoming ridiculous. Photographers and film makers went far beyond them. Already it could be said that a good portrait led one to think about the painter not the model."
"I wanted an art that was faithful to itself [loyal] and would have nothing to do with the business of creating illusions. I dreamed of painting glasses from which no-one would ever think of drinking, beaches that would be quite unsuitable for bathing, nudes who would be definitively chaste. I wanted an art which in the first place would appear as a representation of the impossible."
"It should be said that such an art would be neither more false nor more true than classical art."
"Gleizes was only trying to reduce the curvature of natural volumes to adapt them more naturally and rigorously to the surface of the painting, a surface which he believed to be continuous with the wall and, for all practical purposes, with no curvature at all."
"Art belongs to the domain of the unreal and it is only when people try to make a reality of it that it falls apart."
"I learned that Cézanne's success was not preventing the Neo-Impressionists from getting support. My knowledge of their technique was entirely literary."
"Nearly conscious in someone like Michelangelo, or Paolo Uccello, quite intuitive in painters such as Ingres, or Corot, it works on the basis of numbers which belong to the painting itself, not to whatever it represents."
"Often we were joined by Maurice Princet. Although very young, he held an important post in an insurance company which he owed to his knowledge of mathematics. But outside his profession it was as an artist that he thought of mathematics, as a specialist in aesthetics that he evoked continuities in n dimensions. He liked to interest painters in the new visions of space that had been opened up by Victor Schlegel and several others. He succeeded. After having heard him by chance, Henri Matisse was caught reading an essay on hyperspace. Oh! it was only a potboiler [un ouvrage de vulgarisation]! but at least that shows that for the great 'fauve' the days of the painter who knows nothing, who runs towards a pretty subject with his beard blowing in the wind, was passed."
"As for Picasso, the specialist was amazed by the rapidity of his understanding. The tradition he came from had prepared him better than ours for a problem to do with structure. And Berthe Weil was right when she treated those who compared him/confused him with, a Steinlen or a Lautrec as idiots. He had already rejected them in their own century, a century we had no intention of prolonging. Whether or not the Universe was endowed with another dimension, art was going to move into a different field."
"This science gave me a taste for the arts. It is Number that gives value to sounds and silences, lights and shadows, forms and spaces. Michelangelo and Bach seemed to me like divine mathematicians [calculateurs]. Already I felt that only mathematics enables works that can last. Whether as a result of patient study, or of a stormy [fulgurante] intuition, number alone can reduce all our diversities of feeling to the strict unity of a mass, a fresco, or a sculpted head."
"I had measured the difference that separated art prior to 1900 from the art which I felt was being born. I knew that all instruction was at an end. The age of personal expression had finally begun. The value of an artist was no longer to be judged by the finish of his execution, or by the analogies his work suggested with such-and-such an archetype. It would be judged – exclusively – by what distinguished this artist from all the others. The age of the master and pupil was finally over; I could see about me only a handful of creators and whole colonies of monkeys. But I could not ask Gleizes to see it that way. Happily, nothing of his social or mystical opinions remained when he was engaged in the work of painting. The work of reconciling an oval and a lozenge, a yellow and a blue, prevailed and saved him."
"The house was filled with the piano and violin. I turned towards the art of painting."
"My conviction was justified: art, that which lasts, is based on mathematics."
"Let the picture imitate nothing; let it nakedly present its raison d'être. We should indeed be ungrateful were we to deplore the absence of all those things flowers, or landscape, or faces whose mere reflection it might have been. Nevertheless, let us admit that the reminiscence of natural forms cannot be absolutely banished; not yet, at all events. An art cannot be raised to the level of a pure effusion at the first step."
"If we wished to relate the space of the [Cubist] painters to geometry, we should have to refer it to the non-Euclidean mathematicians; we should have to study, at some length, certain of Riemann's theorems."
"Unless we are to condemn all modern painting, we must regard cubism as legitimate, for it continues modern methods, and we should see in it the only conception of pictorial art now possible. In other words, at this moment cubism is painting."
"To understand Paul Cézanne is to foresee Cubism. Henceforth we are justified in saying that between this school and previous manifestations there is only a difference of intensity, and that in order to assure ourselves of this we have only to study the methods of this realism, which, departing from the superficial reality of Courbet, plunges with Cézanne into profound reality, growing luminous as it forces the unknowable to retreat."
"Some maintain that such a tendency distorts the curve of tradition. Do they derive their arguments from the future or the past? The future does not belong to them, as far as we are aware, and one be singularly ingenuous to seek to measure that which exists by that which exists no longer."
"We do not mechanically connect the sensation of white with the idea of light, any more than we connect the sensation of black with the idea of darkness. We admit that a black jewel, even if of a dead black, may be more luminous than the white or pink satin of its case. Loving light, we refuse to measure it, and we avoid the geometrical ideas of the focus and the ray, which imply the repetition-contrary to the principle of variety which guides us-of bright planes and sombre intervals in a given direction. Loving colour, we refuse to limit it, and subdued or dazzling, fresh or muddy, we accept all the possibilities contained between the two extreme points of the spectrum, between the cold and the warm tone."
"It used to be said of a woman: why she's a Velázquez infanta! Now it is said: she's a Renoir blonde! I have no doubt that, in the future, it will be proclaimed: she's as exuberant as a Delaunay, as noble as a Le Fauconnier, as beautiful as a Braque or Picasso."
"Cézanne showed us forms living in the reality of light; Picasso gives us a material report of their real life in the mind. He establishes a free, mobile perspective, in such a way that the shrewd mathematician Maurice Princet has deduced an entire geometry."
