“The Italian command was, for the most part, not equal to the task of carrying on war in the desert, where the requirement was lightning decision followed by immediate action. The training of the Italian infantryman fell far short of the standard required by modern warfare. … Particularly harmful was the all pervading differentiation between officer and man.”

Erwin Rommel (1891–1944) German field marshal of World War II

Source: The Rommel Papers (1953), Ch. XI : The Initiative Passes, p. 262.[[Courage which goes against military expediency is stupidity, or, if it is insisted upon by a commander, irresponsibility.]]
Context: The Italian command was, for the most part, not equal to the task of carrying on war in the desert, where the requirement was lightning decision followed by immediate action. The training of the Italian infantryman fell far short of the standard required by modern warfare. … Particularly harmful was the all pervading differentiation between officer and man. While the men had to make shift without field-kitchens, the officers, or many of them, refused adamantly to forgo their several course meals. Many officers, again, considered it unnecessary to put in an appearance during battle and thus set the men an example. All in all, therefore, it was small wonder that the Italian soldier, who incidentally was extraordinarily modest in his needs, developed a feeling of inferiority which accounted for his occasional failure and moments of crisis. There was no foreseeable hope of a change for the better in any of these matters, although many of the bigger men among the Italian officers were making sincere efforts in that direction.

“It is sometimes helpful to differentiate between the God of Miracles and the God of Order.”

Source: Hyperspace (1995), Ch.15 Conclusion<!--pp.330-331-->
Context: It is sometimes helpful to differentiate between the God of Miracles and the God of Order. When scientists use the word God, they usually mean the God of Order.... The God of Miracles intervenes in our affairs, performs miracles, destroys wicked cities, smites enemy armies, drowns the Pharaoh's troops, and avenges the pure and noble.... This is not to say that miracles cannot happen, only that they are outside what is commonly called science.

“Who will co-ordinate these value scales, and how? Who will create for mankind one system of interpretation, valid for good and evil deeds, for the unbearable and the bearable, as they are differentiated today? Who will make clear to mankind what is really heavy and intolerable and what only grazes the skin locally? Who will direct the anger to that which is most terrible and not to that which is nearer?”

Aleksandr Solzhenitsyn (1918–2008) Russian writer

Nobel lecture (1970)
Context: Who will co-ordinate these value scales, and how? Who will create for mankind one system of interpretation, valid for good and evil deeds, for the unbearable and the bearable, as they are differentiated today? Who will make clear to mankind what is really heavy and intolerable and what only grazes the skin locally? Who will direct the anger to that which is most terrible and not to that which is nearer? Who might succeed in transferring such an understanding beyond the limits of his own human experience? Who might succeed in impressing upon a bigoted, stubborn human creature the distant joy and grief of others, an understanding of dimensions and deceptions which he himself has never experienced? Propaganda, constraint, scientific proof — all are useless. But fortunately there does exist such a means in our world! That means is art. That means is literature.
They can perform a miracle: they can overcome man's detrimental peculiarity of learning only from personal experience so that the experience of other people passes him by in vain. From man to man, as he completes his brief spell on Earth, art transfers the whole weight of an unfamiliar, lifelong experience with all its burdens, its colours, its sap of life; it recreates in the flesh an unknown experience and allows us to possess it as our own.
And even more, much more than that; both countries and whole continents repeat each other's mistakes with time lapses which can amount to centuries. Then, one would think, it would all be so obvious! But no; that which some nations have already experienced, considered and rejected, is suddenly discovered by others to be the latest word. And here again, the only substitute for an experience we ourselves have never lived through is art, literature. They possess a wonderful ability: beyond distinctions of language, custom, social structure, they can convey the life experience of one whole nation to another. To an inexperienced nation they can convey a harsh national trial lasting many decades, at best sparing an entire nation from a superfluous, or mistaken, or even disastrous course, thereby curtailing the meanderings of human history.

“The very fact that religions are not content to stand on their own feet, but insist on crippling or warping the flexible minds of children in their favour, forms a sufficient proof that there is no truth in them. If there were any truth in religion, it would be even more acceptable to a mature mind than to an infant mind—yet no mature mind ever accepts religion unless it has been crippled in infancy. … The whole basis of religion is a symbolic emotionalism which modern knowledge has rendered meaningless & even unhealthy. Today we know that the cosmos is simply a flux of purposeless rearrangement amidst which man is a wholly negligible incident or accident. There is no reason why it should be otherwise, or why we should wish it otherwise. All the florid romancing about man's "dignity", "immortality", &c. &c. is simply egotistical delusions plus primitive ignorance. So, too, are the infantile concepts of "sin" or cosmic "right" & "wrong". Actually, organic life on our planet is simply a momentary spark of no importance or meaning whatsoever. Man matters to nobody except himself. Nor are his "noble" imaginative concepts any proof of the objective reality of the things they visualise. Psychologists understand how these concepts are built up out of fragments of experience, instinct, & misapprehension. Man is essentially a machine of a very complex sort, as La Mettrie recognised nearly 2 centuries ago. He arises through certain typical chemical & physical reactions, & his members gradually break down into their constituent parts & vanish from existence. The idea of personal "immortality" is merely the dream of a child or savage. However, there is nothing anti-ethical or anti-social in such a realistic view of things. Although meaning nothing in the cosmos as a whole, mankind obviously means a good deal to itself. Therefore it must be regulated by customs which shall ensure, for its own benefit, the full development of its various accidental potentialities. It has a fortuitous jumble of reactions, some of which it instinctively seeks to heighten & prolong, & some of which it instinctively seeks to shorten or lessen. Also, we see that certain courses of action tend to increase its radius of comprehension & degree of specialised organisation (things usually promoting the wished-for reactions, & in general removing the species from a clod-like, unorganised state), while other courses of action tend to exert an opposite effect. Now since man means nothing to the cosmos, it is plan that his only logical goal (a goal whose sole reference is to himself) is simply the achievement of a reasonable equilibrium which shall enhance his likelihood of experiencing the sort of reactions he wishes, & which shall help along his natural impulse to increase his differentiation from unorganised force & matter. This goal can be reached only through teaching individual men how best to keep out of each other's way, & how best to reconcile the various conflicting instincts which a haphazard cosmic drift has placed within the breast of the same person. Here, then, is a practical & imperative system of ethics, resting on the firmest possible foundation & being essentially that taught by Epicurus & Lucretius. It has no need of supernatualism, & indeed has nothing to do with it.”

“Notwithstanding the eminent difficulties of the mathematical theory of sonorous vibrations, we owe to it such progress as has yet been made in acoustics. The formation of the differential equations proper to the phenomena is, independent of their integration, a very important acquisition, on account of the approximations which mathematical analysis allows between questions, otherwise heterogeneous, which lead to similar equations. This fundamental property, whose value we have so often to recognize, applies remarkably in the present case; and especially since the creation of mathematical thermology, whose principal equations are strongly analogous to those of vibratory motion. This means of investigation is all the more valuable on account of the difficulties in the way of direct inquiry into the phenomena of sound. We may decide the necessity of the atmospheric medium for the transmission of sonorous vibrations; and we may conceive of the possibility of determining by experiment the duration of the propagation, in the air, and then through other media; but the general laws of the vibrations of sonorous bodies escape immediate observation. We should know almost nothing of the whole case if the mathematical theory did not come in to connect the different phenomena of sound, enabling us to substitute for direct observation an equivalent examination of more favorable cases subjected to the same law. For instance, when the analysis of the problem of vibrating chords has shown us that, other things being equal, the number of oscillations is hi inverse proportion to the length of the chord, we see that the most rapid vibrations of a very short chord may be counted, since the law enables us to direct our attention to very slow vibrations. The same substitution is at our command in many cases in which it is less direct.”

“Of the complete biological inferiority of the negro there can be no question—he has anatomical features consistently varying from those of other stocks, & always in the direction of the lower primates... Equally inferior—& perhaps even more so—is the Australian black stock, which differs widely from the real negro... In dealing with these two black races, there is only one sound attitude for any other race (be it white, Indian, Malay, Polynesian, or Mongolian) to take—& that is to prevent admixture as completely & determinedly as it can be prevented, through the establishment of a colour-line & the rigid forcing of all mixed offspring below that line. I am in accord with the most vehement & vociferous Alabaman or Mississippian on that point … Other racial questions are wholly different in nature—involving wide variations unconnected with superiority or inferiority. Only an ignorant dolt would attempt to call a Chinese gentleman—heir to one of the greatest artistic & philosophic traditions in the world—an "inferior" of any sort... & yet there are potent reasons, based on wide physical, mental, & cultural differences, why great numbers of the Chinese ought not to mix into the Caucasian fabric, or vice versa. It is not that one race is any better than any other, but that their whole respective heritages are so antipodal as to make harmonious adjustment impossible. Members of one race can fit into another only through the complete eradication of their own background-influences—& even then the adjustment will always remain uneasy & imperfect if the newcomer's physical aspect froms a constant reminder of his outside origin. Therefore it is wise to discourage all mixtures of sharply differentiated races—though the color-line does not need to be drawn as strictly as in the case of the negro, since we know that a dash or two of Mongolian or Indian or Hindoo or some such blood will not actually injure a white stock biologically.... As a matter of fact, most of the psychological race-differences which strike us so prominently are cultural rather than biological. If one could take a Japanese infant, alter his features to the Anglo-Saxon type through plastic surgery, & place him with an American family in Boston for rearing—without telling him that he is not an American—the chances are that in 20 years the result would be a typical American youth with very few instincts to distinguish him from his pure Nordic college-mates. The same is true of other superior alien races including the Jew—although the Nazis persist in acting on a false biological conception. If they were wise in their campaign to get rid of Jewish cultural influences (& a great deal can be said for such a campaign, when the dominance of the Aryan tradition is threatened as in Germany & New York City), they would not emphasize the separatism of the Jew but would strive to make him give up his separate culture & lose himself in the German people. It wouldn't hurt Germany—or alter its essential physical type—to take in all the Jews it now has.”

H.P. Lovecraft (1890–1937) American author

However, that wouldn't work in Poland or New York City, where the Jews are of an inferior strain, & so numerous that they would essentially modify the physical type.

My job was to live through Friday afternoon, get through the week, and eat something.

“Every archetype is capable of endless development and differentiation.”

Psychology and Alchemy (1952)
Context: Every archetype is capable of endless development and differentiation. It is therefore possible for it to be more developed or less. In an outward form of religion where all the emphasis is on the outward figure (hence where we are dealing with a more or less complete projection) the archetype is identical with externalized ideas but remains unconscious as a psychic factor. When an unconscious content is replaced by a projected image to that extent, it is cut off from all participation in an influence on the conscious mind. Hence it largely forfeits its own life, because prevented from exerting the formative influence on consciousness natural to it; what is more, it remains in its original form — unchanged, for nothing changes in the unconscious.

“This situation [alienation] can therefore [according to Durkheim] be remedied by providing the individual with a moral awareness of the social importance of his particular role in the division of labour. He is then no longer an alienated automaton. but is a useful part of an organic whole: ‘from that time, as special and uniform as his activity may be, it is that of an intelligent being, for it has direction, and he is aware of it.’ This is entirely consistent with Durkheim’s general account of the growth of the division of labour, and its relationship to human freedom. It is only through moral acceptance in his particular role in the division of labour that the individual is able to achieve a high degree of autonomy as a self-conscious being, and can escape both the tyranny of rigid moral conformity demanded in undifferentiated societies on the one hand and the tyranny of unrealisable desires on the other.
Not the moral integration of the individual within a differentiated division of labour but the effective dissolution of the division of labour as an organising principle of human social intercourse, is the premise of Marx’s conception. Marx nowhere specifies in detail how this future society would be organised socially, but, at any rate,. this perspective differs decisively from that of Durkheim. The vision of a highly differentiated division of labour integrated upon the basis of moral norms of individual obligation and corporate solidarity. is quite at variance with Marx’s anticipation of the future form of society.
According to Durkheim’s standpoint. the criteria underlying Marx’s hopes for the elimination of technological alienation represent a reversion to moral principles which are no longer appropriate to the modern form of society. This is exactly the problem which Durkheim poses at the opening of The Division of Labour: ‘Is it our duty to seek to become a thorough and complete human being. one quite sufficient unto himself; or, on the contrary, to be only a part of a whole, the organ of an organism?’ The analysis contained in the work, in Durkheim’s view, demonstrates conclusively that organic solidarity is the ‘normal’ type in modern societies, and consequently that the era of the ‘universal man’ is finished. The latter ideal, which predominated up to the seventeenth and eighteenth centuries in western Europe is incompatible with the diversity of the contemporary order. In preserving this ideal. by contrast. Marx argues the obverse: that the tendencies which are leading to the destruction of capitalism are themselves capable of effecting a recovery of the ‘universal’ properties of man. which are shared by every individual.”

“The first period embraces the time between the first records of empirical determinations of the ratio of the circumference to the diameter of a circle until the invention of the Differential and Integral Calculus, in the middle of the seventeenth century. This period, in which the ideal of an exact construction was never entirely lost sight of, and was occasionally supposed to have been attained, was the geometrical period, in which the main activity consisted in the approximate determination of π by the calculation of the sides or the areas of regular polygons in- and circum-scribed to the circle. The theoretical groundwork of the method was the Greek method of Exhaustions. In the earlier part of the period the work of approximation was much hampered by the backward condition of arithmetic due to the fact that our present system of numerical notation had not yet been invented; but the closeness of the approximations obtained in spite of this great obstacle are truly surprising. In the later part of this first period methods were devised by which the approximations to the value of π were obtained which required only a fraction of the labour involved in the earlier calculations. At the end of the period the method was developed to so high a degree of perfection that no further advance could be hoped for on the lines laid down by the Greek Mathematicians; for further progress more powerful methods were required.”

“By following up this idea, also, we might go a little further. We might arrive at the conviction that our present science is human, petty, and contingent; that it is closely linked with the structure of our sensory organs; that this structure results from the evolution which fashioned these organs; that this evolution has been an accident of history; that in the future it may be different; and that, consequently, by the side or in the stead of our modern science, the work of our eyes and hands—and also of our words—there might have been constituted, there may still be constituted, sciences entirely and extraordinarily new—auditory, olfactory, and gustatory sciences, and even others derived from other kinds of sensations which we can neither foresee nor conceive because they are not, for the moment, differentiated in us. Outside the matter we know, a very special matter fashioned of vision and touch, there may exist other matter with totally different properties. …We must, by setting aside the mechanical theory, free ourselves from a too narrow conception of the constitution of matter. And this liberation will be to us a great advantage which we shall soon reap. We shall avoid the error of believing that mechanics is the only real thing and that all that cannot be explained by mechanics must be incomprehensible. We shall then gain more liberty of mind for understanding what the union of the soul with the body may be.”

“Let me start a different/ analysis by recalling an idea from Max Weber. He characterized cultural modernity as the separation of the substantive reason expressed in religion and metaphysics into three autonomous spheres. They are science, morality and art. These came to be differentiated because the unified world-views of religion and metaphysics fell apart. Since the 18th century, the problems inherited from these older world-views could be arranged so as to fall under specific aspects of validity: truth, normative rightness, authenticity and beauty. They could then be handled as questions of knowledge, or of justice and morality, or of taste. Scientific discourse, theories of morality, Jurisprudence, and the production and criticism of art could in turn be institutionalized. Each domain of culture could be made to correspond to cultural professions in which problems could be dealt with as the concern of special experts. This professionalized treatment of the cultural tradition brings to the fore the intrinsic structures of each of the three dimensions of culture. There appear the structures of cognitive-instrumental, of moral-practical and of aesthetic-expressive rationality, each of these under the control of specialists who seem more adept at being logical in these particular ways than other people are. As a result, the distance grows between the culture of the experts and that of the larger public. What accrues to culture through specialized treatment and reflection does not immediately and necessarily become the property of everyday praxis. With cultural rationalization of this sort, the threat increases that the life-world, whose traditional substance has already been devalued, will become more and more impoverished.”

“Smith’s own theory, as given in the first five editions, is for the most part a theory of moral judgement —that is to say, it is an answer to the second question set out in the initial description of the subject of philosophical ethics. […] There is no thoroughgoing inquiry of what constitutes the character of virtue, as required by the first of the two questions, even though the historical survey at the end of the book deals with both questions in turn and, as it happens, gives more space to the first topic, the character of virtue, than to the second, the nature of moral judgement.
The fact is that Smith did not reach a distinctive view on the first topic. He has a distinctive view of the content of virtue, that is to say, a view of what are the cardinal virtues; but he does not give us an explanation of what is meant by the concept of moral virtue, how it arises, how it differentiates moral excellence from other forms of human excellence. […] I think that, when Smith came to revise the work for the sixth edition, he realized that he had not dealt at all adequately with the first of the two questions, and for that reason he added the new part VI, entitled ‘Of the Character of Virtue’, to remedy the omission. It is not, in my opinion, an adequate remedy, and it certainly does not match Smith’s elaborate answer to the second question. […]
Since the second of the two topics, the nature of moral judgement, is the main subject of both versions of Smith’s book, I shall give it priority in what follows. There is in fact a clear development in Smith’s view of this topic, especially in his conception of the impartial spectator, the most important element of Smith’s ethical theory.”

“The fact that Fred and I were in no way similar - nor were we the best male dancers around never occurred to the public or the journalists who wrote about us…Fred and I got the cream of the publicity and naturally we were compared. And while I personally was proud of the comparison, because there was no-one to touch Fred when it came to "popular" dance, we felt that people, especially film critics at the time, should have made an attempt to differentiate between our two styles. Fred and I both got a bit edgy after our names were mentioned in the same breath. I was the Marlon Brando of dancers, and he the Cary Grant. My approach was completely different from his, and we wanted the world to realise this, and not lump us together like peas in a pod. If there was any resentment on our behalf, it certainly wasn't with each other, but with people who talked about two highly individual dancers as if they were one person. For a start, the sort of wardrobe I wore - blue jeans, sweatshirt, sneakers - Fred wouldn't have been caught dead in. Fred always looked immaculate in rehearsals, I was always in an old shirt. Fred's steps were small, neat, graceful and intimate - mine were ballet-oriented and very athletic. The two of us couldn't have been more different, yet the public insisted on thinking of us as rivals…I persuaded him to put on his dancing shoes again, and replace me in Easter Parade after I'd broken my ankle.

“As a metaphor - and I stress that it is intended as a metaphor - the concept of an invariant that arises out of mutually or cyclically balancing changes may help us to approach the concept of self. In cybernetics this metaphor is implemented in the ‘closed loop’, the circular arrangement of feedback mechanisms that maintain a given value within certain limits. They work toward an invariant, but the invariant is achieved not by a steady resistance, the way a rock stands unmoved in the wind, but by compensation over time. Whenever we happen to look in a feedback loop, we find the present act pitted against the immediate past, but already on the way to being compensated itself by the immediate future. The invariant the system achieves can, therefore, never be found or frozen in a single element because, by its very nature, it consists in one or more relationships - and relationships are not in things but between them.
If the self, as I suggest, is a relational entity, it cannot have a locus in the world of experiential objects. It does not reside in the heart, as Aristotle thought, nor in the brain, as we tend to think today. It resides in no place at all, but merely manifests itself in the continuity of our acts of differentiating and relating and in the intuitive certainty we have that our experience is truly ours.”

“In the preface to the reissue of Risk, Uncertainty and Profit, Frank Knight makes the penetrating observation that under the conditions envisaged above the velocity of circulation would become infinite and so would the price level. This is perhaps an over-dramatic way of saying that nobody would hold money, and it would become a free good to go into the category of shell and other things which once served as money. We should expect too that it would not only pass out of circulation, but it would cease to be used as a conventional numeraire in terms of which prices are expressed. Interest bearing money would emerge. Of course, the above does not happen in real life, precisely because uncertainty, contingency needs, non-synchronization of revenues and outlay, transaction frictions, etc., etc., all are with us. But the abstract special case analyzed above should warn us against the facile assumption that the average levels of the structure of interest rates are determined solely or primarily by these differential factors. At times they are primary, and at other times, such as the twenties in this country, they may not be. As a generalization I should hazard the hypothesis that they are likely to be of great importance in an economy in which there is a “quasi-zero" rate of interest. I think by this hypothesis one can explain many of the anomalies of the United States money market in the thirties.”

“In this chapter I shall collect those Theorems in the Differential Calculus which, depending only on the laws of combination of the symbols of differentiation, and not on the functions which are operated on by these symbols, may be proved by the method of the separation of the symbols : but as the principles of this method have not as yet found a place in the elementary works on the Calculus, I shall first state? briefly the theory on which it is founded.”

“The Rigveda stated that the earth was a …globe suspended freely in space. The Vedic texts disclosed that the Sun held the earth and heavenly bodies in its orbit. The Shatapatha Brahmana, a treatise of untold antiquity, recognized and explained the fact that the earth was spherical.. Aryabhata explained the daily rising and setting of planets and stars in terms of the earth’s constant revolutionary motion. The Surya Siddhantha said that the earth, owing to its gravitational force draw all things to itself. In physics, the thinker Kanada, explained light and heat as different aspects of the same element, thus anticipating Clarke Maxwell's Electro-magnetic Theory, which unified different forms of radiant energy. Sankaracharya, in his Advaita thought expanded the concept of unity of matter and energy. Vacaspati recognized light as composed of minute particles emitted by substances, anticipating Newton’s Corpuscular Theory of Light and the later discovery of the Photon. In Botany, Sankara Mishra and Kanada have discussed the circulation of sap in the Plant and the Santiparva of Mahabharata has clearly stated that the plants develop on the strength of nutrients made through interaction of sunlight and materials obtained from the air and ground. Bhaskarcharya's concept of Differential Calculus preceded Newton by many centuries. His study of time identified Truti: The 3400th part of a second as the unit of time.”
