"Ideas do not make a movement; they are themselves merely the product of concrete situations, the intellectual precipitate of particular conditions of life. Movements arise only from the immediate and practical necessities of social life and are never the result of purely abstract ideas. But they acquire their irresistible force and their inner certainty of victory only when they are vitalised by a great idea, which gives them life and intellectual content."
"Power operates only destructively, bent always on forcing every manifestation of life into the straitjacket of its laws. Its intellectual form of expression is dead dogma, its physical form brute force. And this unintelligence of its objectives sets its stamp on its supporters also and renders them stupid and brutal, even when they were originally endowed with the best of talents. One who is constantly striving to force everything into a mechanical order at last becomes a machine himself and loses all human feeling. It was from the understanding of this that modern Anarchism was born and now draws its moral force. Only freedom can inspire men to great things and bring about social and political transformations. The art of ruling men has never been the art of educating men and inspiring them to a new shaping of their lives. Dreary compulsion has at its command only lifeless drill, which smothers any vital initiative at its birth and can bring forth only subjects, not free men. Freedom is the very essence of life, the impelling force in all intellectual and social development, the creator of every new outlook for the future of mankind. The liberation of man from economic exploitation and from intellectual and political oppression, which finds its finest expression in the world-philosophy of Anarchism, is the first prerequisite for the evolution of a higher social culture and a new humanity."
"Every culture, if its natural development is not too much affected by political restrictions, experiences a perpetual renewal of the formative urge, and out of that comes an ever growing diversity of creative activity. Every successful piece of work stirs the desire for greater perfection and deeper inspiration; each new form becomes the herald of new possibilities of development."
"Anarchism recognises only the relative significance of ideas, institutions, and social conditions. It is, therefore not a fixed, self enclosed social system, but rather a definite trend in the historical development of mankind, which, in contrast with the intellectual guardianship of all clerical and governmental institutions, strives for the free unhindered unfolding of all the individual and social forces in life. Even freedom is only a relative, not an absolute concept, since it tends constantly to broaden its scope and to affect wider circles in manifold ways. For the Anarchist, freedom is not an abstract philosophical concept, but the vital concrete possibility for every human being to bring to full development all capacities and talents with which nature has endowed him, and turn them to social account. The less this natural development of man is interfered with by ecclesiastical or political guardianship, the more efficient and harmonious will human personality become, the more will it become the measure of the intellectual culture of the society in which it has grown."
"Anarchism is no patent solution for all human problems, no Utopia of a perfect social order, as it has so often been called, since on principle it rejects all absolute schemes and concepts. It does not believe in any absolute truth, or in definite final goals for human development, but in an unlimited perfectibility of social arrangements and human living conditions, which are always straining after higher forms of expression, and to which for this reason one can assign no definite terminus nor set any fixed goal. The worst crime of any type of state is just that it always tries to force the rich diversity of social life into definite forms and adjust it to one particular form, which allows for no wider outlook and regards the previously exciting status as finished. The stronger its supporters feel themselves, the more completely they succeed in bringing every field of social life into their service, the more crippling is their influence on the operation of all creative cultural forces, the more unwholesomely does it affect the intellectual and social development of any particular epoch."
"The economic dictatorship of the monopolies and the political dictatorship of the totalitarian state are the outgrowth of the same political objectives, and the directors of both have the presumption to try to reduce all the countless expressions of social life to the mechanical tempo of the machine and to tune everything organic to the lifeless machine of the political apparatus. Our modern social system has split the social organism in every country into hostile classes internally, and externally it has broken the common cultural circle up into hostile nations; and both classes and nations confront one another with open antagonism and by their ceaseless warfare keep the communal social life in continual convulsions."
"Anarchism is a definite intellectual current in the life of our times, whose adherents advocate the abolition of economic monopolies and of all political and social coercive institutions within society. In place of the present capitalistic economic order Anarchists would have a free association of all productive forces based upon co-operative labour, which would have as its sole purpose the satisfying of the necessary requirements of every member of society, and would no longer have in view the special interest of privileged minorities within the social union. In place of the present state organisation with their lifeless machinery of political and bureaucratic institutions Anarchists desire a federation of free communities which shall be bound to one another by their common economic and social interest and shall arrange their affairs by mutual agreement and free contract."
"For the machine, because of the way it is built, can work only in a given direction, no matter who pulls its levers."
"The growth of technology at the expense of human personality, and especially the fatalistic submission with which the great majority surrender to this condition, is the reason why the desire for freedom is less alive among men today and has with many of them given place completely to a desire for economic security. This phenomenon need not appear so strange, for our whole evolution has reached a stage where nearly every man is either ruler or ruled; sometimes he is both. By this the attitude of dependence has been greatly strengthened, for a truly free man does not like to play the part of either the ruler or the ruled. He is, above all, concerned with making his inner values and personal powers effective in a way as to permit him to use his own judgment in all affairs and to be independent in action. Constant tutelage of our acting and thinking has made us weak and irresponsible; hence, the continued cry for the strong man who is to put an end to our distress. This call for a dictator is not a sign of strength, but a proof of inner lack of assurance and of weakness, even though those who utter it earnestly try to give themselves the appearance of resolution. What man most lacks he most desires. When one feels himself weak he seeks salvation from another's strength; when one is cowardly or too timid to move one's own hands for the forging of one's fate, one entrusts it to another. How right was Seume when he said: "The nation which can only be saved by one man and wants to be saved that way deserves a whipping!""
"To maintain this state of things we make all our achievements in science and technology serve organised mass murder; we educate our youth into uniformed killers, deliver the people to the soulless tyranny of a bureaucracy, put men from the cradle to the grave under police supervision, erect everywhere jails and penitentiaries, and fill every land with whole armies of informers and spies. Should not such "order," from whose infected womb are born eternally brutal power, injustice, lies, crime and moral rottennesslike poisonous germs of destructive plagues gradually convince even conservative minds that it is order too dearly bought?"
"We have increased and developed our technical ability to a degree which appears almost fantastic, and yet man has not become richer thereby; on the contrary he has become poorer. Our whole industry is in a state of constant insecurity. And while billions of wealth are criminally destroyed in order to maintain prices, in every country millions of men live in the most frightful poverty or perish miserably in a world of abundance and so-called "overproduction." The machine, which was to have made work easier for men, has made it harder and has gradually changed its inventor himself into a machine who must adjust himself to every motion of the steel gears and levers. And just as they calculate the capacity of the marvellous mechanism to the tiniest fraction, they also calculate the muscle and nerve force of the living producers by definite scientific methods and will not realise that thereby they rob him of his soul and most deeply defile his humanity. We have come more and more under the dominance of mechanics and sacrificed living humanity to the dead rhythm of the machine without most of us even being conscious of the monstrosity of the procedure. Hence we frequently deal with such matters with indifference and in cold blood as if we handled dead things and not the destinies of men."
"This Caesarean madness stops at no barrier. Without compunction it rides roughshod over those achievements of the past which have all too often had to be purchased with the heart's blood of the people. It is always ready to smother with brutal violence the last rights and the last liberties which might interfere with its plans for holding all social activities within the rigid forms set by its will. This is the great danger which threatens us today and which immediately confronts us. The success or failure of monopolistic capitalistic power plans will determine the structure of the social life of the near future."
"Because of his social position there are left no limits to the power lust of the modern capitalist. He can interfere with inconsiderate egoism in the lives of his fellowmen and play the part of Providence for others. Only when we take into consideration this passionate urge for political power over their own people as well as over foreign nations are we able really to understand the character of the typical representatives of modern capitalism. It is just this trait which makes them so dangerous to the social structure of the future."
"The view which sees in every capitalist only a profit machine may very well meet the demands of propaganda, but it is conceived much too narrowly and does not correspond to reality. Even in modern giant capitalism the power-political interests frequently play a larger part than the purely economic considerations, although it is difficult to separate them from each other... The morbid desire to make millions of men submissive to a definite will and to force whole empires into courses which are useful to the secret purposes of small minorities, is frequently more evident in the typical representatives of modern capitalism than are purely economic considerations or the prospect of greater material profit. The desire to heap up ever increasing profits today no longer satisfies the demands of the great capitalistic oligarchies. Every one of its members knows what enormous power the possession of great wealth places in the hands of the individual and the caste to which he belongs. This knowledge gives a tempting incentive and creates that typical consciousness of mastery whose consequences are frequently more destructive than the facts of monopoly itself."
"The will to power which always emanates from individuals or from small minorities in society is in fact a most important driving force in history. The extent of its influence has up to now been regarded far too little, although it has frequently been the determining factor in the shaping of the whole of economic and social life."
"No thinking man in this day can fail to recognise that one cannot properly evaluate an historical period without considering economic conditions. But much more one-sided is the view which maintains that all history is merely the result of economic conditions, under whose influence all other life phenomena have received form and imprint. There are thousands of events in history which cannot be explained by purely economic reasons, or by them alone. It is quite possible to bring everything within the terms of a definite scheme, but the result is usually not worth the effort. There is scarcely an historical event to whose shaping economic causes have not contributed, but economic forces are not the only motive powers which have set everything else in motion. All social phenomena are the result of a series of various causes, in most cases so inwardly related that it is quite impossible clearly to separate one from the other. We are always dealing with the interplay of various causes which, as a rule, can be clearly recognised but cannot be calculated according to scientific methods."
"However fully man may recognise cosmic laws he will never be able to change them, because they are not his work. But every form of his social existence, every social institution which the past has bestowed on him as a legacy from remote ancestors, is the work of men and can be changed by human will and action or made to serve new ends. Only such an understanding is truly revolutionary and animated by the spirit of the coming ages. Whoever believes in the necessary sequence of all historical events sacrifices the future to the past. He explains the phenomena of social life, but he does not change them. In this respect all fatalism is alike, whether of a religious, political or economic nature. Whoever is caught in its snare is robbed thereby of life's most precious possession; the impulse to act according to his own needs. It is especially dangerous when fatalism appears in the gown of science, which nowadays so often replaces the cassock of the theologian; therefore we repeat: The causes which underlie the processes of social life have nothing in common with the laws of physical and mechanical natural events, for they are purely the results of human purpose, which is not explicable by scientific methods. To misinterpret this fact is a fatal self-deception from which only a confused notion of reality can result."
"Every process which arises from our physical being and is related to it, is an event which lies outside of our volition. Every social process, however, arises from human intentions and human goal setting and occurs within the limits of our volition. Consequently, it is not subject to the concept of natural necessity. … We are here stating no prejudiced opinion, but merely an established fact. Every result of human purposiveness is of indisputable importance for man's social existence, but we should stop regarding social processes as deterministic manifestations of a necessary course of events. Such a view can only lead to the most erroneous conclusions and contribute to a fatal confusion in our understanding of historical events. It is doubtless the task of the historian to trace the inner connection of historical events and to make clear their causes and effects, but he must not forget that these connections are of a sort quite different from those of natural physical events and must therefore have quite a different valuation."
"The deeper we trace the political influences in history, the more are we convinced that the "will to power" has up to now been one of the strongest motives in the development of human social forms. The idea that all political and social events are but the result of given economic conditions and can be explained by them cannot endure careful consideration. That economic conditions and the special forms of social production have played a part in the evolution of humanity everyone knows who has been seriously trying to reach the foundations of social phenomena. This fact was well known before Marx set out to explain it in his manner. A whole line of eminent French socialists like Saint–Simon, Considerant, Louis Blanc, Proudhon and many others had pointed to it in their writings, and it is known that Marx reached socialism by the study of these very writings."
"For two decades the supporters of Bolshevism have been hammering it into the masses that dictatorship is a vital necessity for the defense of the so-called proletarian interests against the assaults of and for paving the way for Socialism. They have not advanced the cause of Socialism by this propaganda, but have merely smoothed the way for Fascism in Italy, Germany and Austria by causing millions of people to forget that dictatorship, the most extreme form of tyranny, can never lead to social liberation. In Russia, the so-called dictatorship of the proletariat has not led to Socialism, but to the domination of a new bureaucracy over the proletariat and the whole people. … What the Russian autocrats and their supporters fear most is that the success of in Spain might prove to their blind followers that the much vaunted "necessity of dictatorship" is nothing but one vast fraud which in Russia has led to the despotism of Stalin and is to serve today in Spain to help the counter-revolution to a victory over the revolution of the workers and the peasants."
"I am an Anarchist not because I believe Anarchism is the final goal, but because there is no such thing as a final goal."
"My very worst worries are Rudolf’s tours, they are killing us both. If only we could get along without lecture-tours we would both be happy. But alas, how should we exist? I don’t know how it was at your time here, now lecture tours are physical and mainly mental torture. Rudolf simply loaths it and he is the most miserable man in the world when he is on route. He never enjoyed speaking, but worst of all when he has to lecture in Yiddish or English. The tour begun very miserably, his mood is simply terrible. He was happy at his work, he lived in it, got young once more, and it was a pleasue to see him at his desk. Now he had to put it aside and take up work which instead of being a pleasure is a physical and mental torture, so you can imagine how he must feel."
"You will be glad to hear Sasha dear that also Rudolf has started to work, at last: he actually begun to write his memoirs...Never before he was in such a state of spirit and how happy I am to see him in his present state. He is so absorbed by his work that I cannot get him away from the desk. A new spirit came over him, living through once more every phase of his youth. He has only done two chapters by now, but you can tell already that it is going to be a very interesting work, and I hope a valuable document."
"We cannot hope to give here a final clarification of the essence of fact, judgement, object, property; this task leads into metaphysical abysses; about these one has to seek advice from men whose name cannot be stated without earning a compassionate smile—e.g. Fichte."
"Quantum theory does not trouble me at all. It is just the way the world works. What eats me, gets me, drives me, pushes me, is to understand how it got that way. What is the deeper foundation underneath it? Where does it come from? So that we won’t see it as something that is unwelcome by friends that we admire—John Bell and many others—it will be something that will make you say, ‘It couldn’t have been otherwise.’ We haven’t gotten to that stage yet, and until we do, we have not met the challenge that is right there. I continue to say that the quantum is the crack in the armor that covers the secret of existence. To me it’s a marvelous stimulus, hope, and driving force. And yet I am afraid that just the word—‘hope’—is what does not eat, or possess, or drive so many of our colleagues in the field. They’re content to take the theory for granted, rather than to find out where it comes from. But you would hardly feel the drive to find out where from if you don’t feel that the theory is utterly right. I have been brought up from ‘childhood’ to feel that it is utterly right. Here I was, reading that book of Weyl’s at the age of eighteen and just crazy about it."
"He realized that formal mathematics might even have an advantage over immediately insightful ("phenomenological") mathematics, because in its conceptual constitution it was free from the restrictions of the latter. I will call this view the symbolic realism of the "mature" Weyl."
"Weyl never became a devoted adherent to any single philosophy. He rather was a wanderer through the philosophical fields differing with the changes in his scientific view..."
"Weyl considered an aspect about general relativity... the nonpreservation of direction in a curved space. ...[He] decided to consider the possibility that length was also not preserved. ...To effect this change mathematically, Weyl had to make a slight modification in the structure of general relativity. He assumed that in addition to the usual metric (set of numbers or variables) that described the gravitational field, there was another one related to length. ...amazingly when the result was analyzed Maxwell's equations mysteriously appeared. It almost seemed as if a bit of magic had occurred and scientists quickly became interested in the miracle. ...but with detailed analysis the theory was shown to be flawed. Einstein was the first to put his finger on the flaw. ...Weyl soon acknowledged the flaw and laid his theory to rest. It may have been a failure (actually it was not an entire failure; a similar idea is used today in modern field theory), but it did accomplish something important: it got people interested in the possibility that the electromagnetic and gravitational field could be unified. Einstein soon began working on an alternative theory, as did others."
"I inquired of Dyson whether Weyl had given an example of his having sacrificed truth for beauty. I learned that the example which Weyl gave was his gauge theory of gravitation which he had worked out in his Raum-Zeit-Materie. Apparently, Weyl became convinced that this theory was not true as a theory of gravitation; but still it was so beautiful that he did not wish to abandon it and so he kept it alive for the sake of beauty. But much later, it did turn out that Weyl's instinct was right after all, when the formalism of gauge invariance was incorporated into quantum electrodynamics."
"In the first attempt to introduce gauge theories in physics, Hermann Weyl, around the 1920s, proposed certain scale transformations to be a fundamental symmetry of nature."
"Hermann Weyl was both a mathematician and a mathematical physicist. Weyl wrote on mathematics, general relativity... quantum mechanics... art and philosophy. His smaller book on philosophy is entitled The Open World. It is made up of lectures... in 1932 at Yale University. In the philosophy of science, according to Weyl, complexity is essential in understanding the concept of a law of nature. If laws of nature may be arbitrarily complex, he argued, the very concept... becomes vacuous. What difference would remain... if the laws meant to explain them were as complex as the phenomena they are meant to explain? Laws of nature must be simple."
"Hermann Weyl’s 1918 text Das Kontinuum... investigates how much of the mathematical corpus can be retained if we restrict ourselves to predicative definitions and methods of proof. He presents a foundational system in which it is impossible to perform an impredicative definition. ...It is an excellent example of a fully developed non-mainstream foundational system for mathematics."
"The scene of action of reality is not a three-dimensional Euclidean space but rather a four-dimensional world, in which space and time are linked together indissolubly. However deep the chasm may be that separates the intuitive nature of space from that of time in our experience, nothing of this qualitative difference enters into the objective world which physics endeavors to crystallize out of direct experience. It is a four-dimensional continuum, which is neither "time" nor "space". Only the consciousness that passes on in one portion of this world experiences the detached piece which comes to meet it and passes behind it as history, that is, as a process that is going forward in time and takes place in space."
"Above all, the ominous clouds of those phenomena that we are with varying success seeking to explain by means of the quantum of action, are throwing their shadows over the sphere of physical knowledge, threatening no one knows what new revolution."
"After Riemann had made known his discoveries, mathematicians busied themselves with working out his system of geometrical ideas formally; chief among these were Christoffel, Ricci, and Levi-Civita. Riemann... clearly left the real development of his ideas in the hands of some subsequent scientist whose genius as a physicist could rise to equal flights with his own as a mathematician. After a lapse of seventy years this mission has been fulfilled by Einstein."
"Consciousness spreads out its web, in the form of time, over reality."
"All characteristics of material things as they are presented to us in the acts of external perception (e.g. colour) are endowed with the separateness of spatial extension, but it is only when we build up a single connected real world out of all our experiences that the spatial extension, which is a constituent of every perception, becomes a part of one and the same all-inclusive space. … every material thing can, without changing content, equally well occupy a position in Space different from its present one. This immediately gives us the property of the homogeneity of space which is the root of the conception, Congruence."
"Time is the primitive form of the stream of consciousness. ...If we project ourselves outside the stream of consciousness and represent its content as an object, it becomes an event happening in time, the separate stages of which stand to one another in the relations of earlier and later."
"It is the nature of a real thing to be inexhaustible in content; we can get an ever deeper insight into this content by the continual addition of new experiences, partly in apparent contradiction, by bringing them into harmony with one another. In this interpretation, things of the real world are approximate ideas. From this arises the empirical character of all our knowledge of reality."
"In the realm of physics it is perhaps only the theory of relativity which has made it quite clear that the two essences, space and time, entering into our intuition, have no place in the world constructed by mathematical physics. Colours are thus "really" not even æther-vibrations, but merely a series of values of mathematical functions in which occur four independent parameters corresponding to the three dimensions of space, and the one of time."
"In the field of philosophy Kant was the first to take the next decisive step towards the point of view that not only the qualities revealed by the senses, but also space and spatial characteristics have no objective significance in the absolute sense; in other words, that space, too, is only a form of our perception."
"Recognition of the subjectivity of the qualities of sense is found in Galilei (and also in Descartes and Hobbes) in a form closely related to the principle underlying the constructive mathematical method of our modern physics which repudiates" qualities"."
"The rapid development of science... has, as it were, burst its old shell, now become too narrow."
"First, the physicists in the persons of Faraday and Maxwell, proposed the "electromagnetic field" in contradistinction to matter, as a reality of a different category. Then, during the last century, the mathematicians, … secretly undermined belief in the evidence of Euclidean Geometry. And now, in our time, there has been unloosed a cataclysm which has swept away space, time, and matter hitherto regarded as the firmest pillars of natural science, but only to make place for a view of things of wider scope and entailing a deeper vision. This revolution was promoted essentially by the thought of one man, Albert Einstein."
"The Greeks made Space the subject-matter of a science of supreme simplicity and certainty. and certainty Out of it grew, in the mind of classical antiquity, the idea of pure science. Geometry became one of the most powerful expressions of that sovereignty of the intellect that inspired the thought of those times. At a later epoch, when the intellectual despotism of the Church... had crumbled, and a wave of scepticism threatened to sweep away all that had seemed most fixed, those who believed in Truth clung to Geometry as to a rock, and it was the highest ideal of every scientist to carry on his science "more geometrico". Matter... could be measured as a quantity and... its characteristic expression as a substance was the Law of Conservation of Matter... This, which has hitherto represented our knowledge of space and matter, and which was in many quarters claimed by philosophers as a priori knowledge, absolutely general and necessary, stands to-day a tottering structure."
"Space and time are commonly regarded as the forms of existence of the real world, matter as its substance. A definite portion of matter occupies a definite part of space at a definite moment of time. It is in the composite idea of motion that these three fundamental conceptions enter into intimate relationship."
"With Mie's view of matter there is contrasted another, according to which matter is a limiting singularity of the field, but charges and masses are force-fluxes in the field. This entails a new and more cautious attitude towards the whole problem of matter."
"A new theory by the author has been added, which draws the physical inferences consequent on the extension of the foundations of geometry beyond Reimann... and represents an attempt to derive from world-geometry not only gravitational but also electromagnetic phenomena. Even if this theory is still only in its infant stage, I feel convinced that it contains no less truth than Einstein's Theory of Gravitation—whether this amount of truth is unlimited or, what is more probable, is bounded by the Quantum Theory."
"To gaze up from the ruins of the oppressive present towards the stars is to recognise the indestructible world of laws, to strengthen faith in reason, to realise the "harmonia mundi" that transfuses all phenomena, and that never has been, nor will be, disturbed."
"It was my wish to present this great subject as an illustration of the itermingling of philosophical, mathematical, and physical thought, a study which is dear to my heart. This could be done only by building up the theory systematically from the foundations, and by restricting attention throughout to the principles. But I have not been able to satisfy these self-imposed requirements: the mathematician predominates at the expense of the philosopher."
