“This investigation aims to analyze the type "bourgeois public sphere". Its particular approach is required, to begin with, by the difficulties specific to an object whose complexity precludes exclusive reliance on the specialized methods of a single discipline. Rather, the category. "public sphere" must be investigated within the broad field formerly reflected in the perspective of the traditional science of "politics."' When particular social-scientific discipline, this object disintegrates. The problems that result from fusing aspects of sociology and economics, of constitutional law and political science, and of social and intellectual history are obvious: given the present state of differentiation and specialization in the social sciences, scarcely anyone will be able to master several, let alone all, of these disciplines.”

“A nonlinear differential equation of the Riccati type is derived for the covariance matrix of the optimal filtering error. The solution of this 'variance equation' completely specifies the optimal filter for either finite or infinite smoothing intervals and stationary or non-stationary statistics.
The variance equation is closely related to the Hamiltonian (canonical) differential equations of the calculus of variations. Analytic solutions are available in some cases. The significance of the variance equation is illustrated by examples which duplicate, simplify, or extend earlier results in this field.
The duality principle relating stochastic estimation and deterministic control problems plays an important role in the proof of theoretical results. In several examples, the estimation problem and its dual are discussed side-by-side.
Properties of the variance equation are of great interest in the theory of adaptive systems. Some aspects of this are considered briefly.”

“[Attlee] reminded the delegates that it was vital to reduce costs by greater efficiency, which meant that both employers and employed had to seek in every way to attain it. He did not believe in lowering wages as a means of reducing costs, but equally it was necessary to realize that increases of wages that were not matched by increases of production would gravely impair their chances of getting rapidly over their difficulties. Increased demands for money payments, when there was no increase of goods to meet them led straight away to inflation. There was a danger that when a justifiable advance in wages for an under-paid section of the workers had been granted it resulted in demands from those who had enjoyed higher wages to maintain the same differential. This was bad economics and bad social morality. He had been disturbed at the evidence that some people were abusing the social services in such matters as sickness benefit. They could not have them sabotaged by misuse.”

“The minimum principle that unified the knowledge of light, gravitation, and electricity of Hamilton's time no longer suffices to relate these fundamental branches of physics. Within fifty years of its creation, the belief that Hamilton's principle would outlive all other physical laws of physics was shattered. Minimum principles have since been created for separate branches of physics… but these are not only restricted… but seem to be contrived…
A single minimum principle, a universal law governing all processes in nature, is still the direction in which the search for simplicity is headed, with the price of simplicity now raised from a mastery of differential equations to a mastery of the calculus of variations.”

“This sketch of how consciousness fits into the wider universe supports a form of non-reductive, Reflexive Monism. Human minds, bodies and brains are embedded in a far greater universe. Individual conscious representations are perspectival. That is, the precise manner in which entities, events and processes are translated into experiences depends on the location in space and time of a given observer, and the exact mix of perceptual, cognitive, affective, social, cultural and historical influences which enter into the 'construction' of a given experience. In this sense, each conscious construction is private, subjective, and unique. Taken together, the contents of consciousness provide a view of the wider universe, giving it the appearance of a 3D phenomenal world. … However, such conscious representations are not the thing-itself. In this vision, there is one universe (the thing-itself), with relatively differentiated parts in the form of conscious beings like ourselves, each with a unique, conscious view of the larger universe of which it is a part. In so far as we are parts of the universe that, in turn, experience the larger universe, we participate in a reflexive process whereby the universe experiences itself.”

“For in the Spirit-World there is Reality; as the process of differentiation proceeds, illusion is produced, and it is this mind, this growing mind, that makes the illusion. It is this growing mind that has endless images and pictures, that has the image-making faculty which we speak of as imagination, that has the reasoning faculty which builds on the airy picture that it has made— it is this which is the real creator of illusion, it is this which slays the Real, so far as the disciple is concerned, and his first work as disciple will be to slay the slayer.”

“Awaken from your ignorance and try at least to understand that, in the uncompromisingly Indivisible Oneness, not only is the Avatar God, but also the ant and the sparrow, just as one and all of you are nothing but God. The only apparent difference is in the states of consciousness. The Avatar knows that that which is a sparrow is not a sparrow, whereas the sparrow does not realize this and, being ignorant of its ignorance, identifies itself as a sparrow.
Live not in ignorance. Do not waste your precious life-span in differentiating and judging your fellowmen, but learn to long for the love of God. Even in the midst of your worldly activities, live only to find and realize your true identity with your Beloved God.”

“I think it is not helpful to apply Darwinian language too widely. Conquest of nation by nation is too distant for Darwinian explanations to be helpful. Darwinism is the differential survival of self-replicating genes in a gene pool, usually as manifested by individual behaviour, morphology, and phenotypes. Group selection of any kind is not Darwinism as Darwin understood it nor as I understand it. There is a very vague analogy between group selection and conquest of a nation by another nation, but I don't think it's a very helpful analogy. So I would prefer not to invoke Darwinian language for that kind of historical interpretation.”

“Gradually… during the second half of the nineteenth century, the uncomfortable feeling of dislike of the action at a distance, which had been so strong in Huygens and other contemporaries of Newton, but had subsided during the eighteenth century, began to emerge again, and gained strength rapidly.
This was favoured by the purely mathematical transformation (which can be compared in a sense with that from the Ptolemaic to the Copernican system), replacing Newton's finite equations by the differential equations, the potential becoming the primary concept, instead of the force, which is only the gradient of the potential. These ideas, of course, arose first in the theory of electricity and magnetism or perhaps one should say in the brain of Faraday.”

“I think the roots of this antagonism to science run very deep. They're ancient. We see them in Genesis, this first story, this founding myth of ours, in which the first humans are doomed and cursed eternally for asking a question, for partaking of the fruit of the "Tree of Knowledge". It's puzzling that Eden is synonymous with paradise when, if you think about it at all, it's more like a maximum-security prison with twenty-four hour surveillance. It's a horrible place. Adam and Eve have no childhood. They awaken full-grown. What is a human being without a childhood? Our long childhood is a critical feature of our species. It differentiates us, to a degree, from most other species. We take a longer time to mature. We depend upon these formative years and the social fabric to learn many of the things we need to know.”

“Even Plato assumes that the genuinely perfect condition of man means no sex distinction (and how strange this is for people like Feuerbach who are so occupied with affirming sex-differentiation, regarding which they would do best to appeal to paganism). He assumes that originally there was only the masculine (and when there is no thought of femininity, sex-distinction is undifferentiated), but through degeneration and corruption the feminine appeared. He assumes that base and cowardly men became women in death, but he still gives them hope of being elevated again to masculinity. He thinks that in the perfect life the masculine, as originally, will be the only sex, that is, that sex-distinction is a matter of indifference. So it is in Plato, and this, the idea of the state notwithstanding, was the culmination of his philosophy. How much more so, then, the Christian view.”

“Early psychology was based on the study of the individual; early sociology was based on the study of society. But there is no such thing as the "individual," there is no such thing as "society"; there is only the group and the group-unit — the social individual. Social psychology must begin with an intensive study of the group, of the selective processes which go on within it, the differentiated reactions, the likenesses and unlikenesses, and the spiritual energy which unites them.”

“When [Born and Heisenberg and the Göttingen theoretical physicists] first discovered matrix mechanics they were having, of course, the same kind of trouble that everybody else had in trying to solve problems and to manipulate and to really do things with matrices. So they had gone to Hilbert for help and Hilbert said the only time he had ever had anything to do with matrices was when they came up as a sort of by-product of the eigenvalues of the boundary-value problem of a differential equation. So if you look for the differential equation which has these matrices you can probably do more with that. They had thought it was a goofy idea and that Hilbert didn’t know what he was talking about. So he was having a lot of fun pointing out to them that they could have discovered Schrödinger’s wave mechanics six month earlier if they had paid a little more attention to him.”

“In the stupendous rush of change which is coming on the human world as a result of the present tornado of upheaval, ancient India's culture, attacked by European modernism, overpowered in the material field, betrayed by the indifference of her children, may perish for ever along with the soul of the nation that holds it in its keeping…. Each nation is a Shakti or power of the evolving spirit in humanity and lives by the principle which it embodies. India is the Bharata Shakti, the living energy of a great spiritual conception, and fidelity to it is the very principle of her existence…. To follow a law or principle involuntarily or ignorantly or contrary to the truth of one's consciousness is a falsehood and a self-destruction. To allow oneself to be killed, like the lamb attacked by the wolf, brings no growth, farthers no development, assures no spiritual merit. Concert or unity may come in good time, but it must be an underlying unity with a free differentiation, not a swallowing up of one by another or an incongruous and inharmonious mixture. Nor can it come before the world is ready for these greater things. To lay down one's arms in a state of war is to invite destruction and it can serve no compensating spiritual purpose…. India is indeed awaking and defending herself, but not sufficiently and not with the whole-heartedness, the clear sight and the firm resolution which can alone save her from the peril. Today it is close; let her choose,… for the choice is imperatively before her, to live or to perish.”

“\frac {dy}{dx} = \frac {\omega^2x}{g}…The first derivative, the result of the differentiation of y with respect to x, was written by Leibniz in the form
\frac {dy}{dx}…Leibniz's notation …is both extremely useful and dangerous. Today, as the concepts of limit and derivative are sufficiently clarified, the use of the notation… need not be dangerous. Yet, the situation was different in the 150 years between the discovery of calculus by Newton and Leibniz and the time of Cauchy. The derivative \frac {dy}{dx} was considered as the ratio of two "infinitely small quanitites", of the infinitesimals dy and dx. …it greatly facilitated the systematization of the rules of the calculus and gave intuitive meaning to its formulas. Yet this consideration was also obscure… it brought mathematics into disrepute… some of the best minds… such as… Berkeley, complained that calculus is incomprehensible. …\frac {dy}{dx} is the limit of a ratio of dy to dx… Once we have realized this sufficiently clearly, we may, under certain circumstances, treat \frac {dy}{dx} so as if it were a ratio… and multiply by dx to achieve the separation of variables. We get
{dy} = \frac {\omega^2x}{g}xdx”

“It is important here to clarify the difference between 'strategic assets' and 'core competences.' Strategic assets are assets that underpin a firm's cost or differentiation advantage in a particular market and that are imperfectly imitable, imperfectly substitutable and imperfectly tradeable. These assets also tend to be market- specific. An example would be Honda's dealer network distributing and servicing its motorbikes. On the other hand, core competences are the pool of experience, knowledge and systems, etc. that can be deployed to reduce the cost or time required in creating or expanding the stock of strategic assets.”

“It is the quality and intensity of the dream only which raises men above the biological norm; and it is fidelity to the dream which differentiates the exceptional figure, the man of heroic stature, from the muddling, aimless mediocrities about him.”

Burton Rascoe (1892–1957) American writer

Introduction to Chivalry (1921) by James Branch Cabell, later published in Prometheans : Ancient and Modern (1933), p. 279
Context: It is true, of course, that like the fruit of the tree of life, Mr. Cabell's artistic progeny sprang from a first conceptual germ — "In the beginning was the Word." That animating idea is the assumption that if life may be said to have an aim it must be an aim to terminate in success and splendor. It postulates the high, fine importance of excess, the choice or discovery of an overwhelming impulse in life and a conscientious dedication to its fullest realization. It is the quality and intensity of the dream only which raises men above the biological norm; and it is fidelity to the dream which differentiates the exceptional figure, the man of heroic stature, from the muddling, aimless mediocrities about him. What the dream is, matters not at all — it may be a dream of sainthood, kingship, love, art, asceticism or sensual pleasure — so long as it is fully expressed with all the resources of self. It is this sort of completion which Mr. Cabell has elected to depict in all his work: the complete sensualist in Demetrios, the complete phrase-maker in Felix Kennaston, the complete poet in Marlowe, the complete lover in Perion. In each he has shown that this complete self-expression is achieved at the expense of all other possible selves, and that herein lies the tragedy of the ideal. Perfection is a costly flower and is cultured only by an uncompromising, strict husbandry.

“The freedom of thought is a sacred right of every individual man, and diversity will continue to increase with the progress, refinement, and differentiation of the human intellect.”

Felix Adler (1851–1933) German American professor of political and social ethics, rationalist, and lecturer

Founding Address (1876)
Context: The freedom of thought is a sacred right of every individual man, and diversity will continue to increase with the progress, refinement, and differentiation of the human intellect. But if difference be inevitable, nay, welcome in thought, there is a sphere in which unanimity and fellowship are above all things needful. Believe or disbelieve as ye list — we shall at all times respect every honest conviction. But be one with us where there is nothing to divide — in action. Diversity in the creed, unanimity in the deed! This is that practical religion from which none dissents. This is that platform broad enough and solid enough to receive the worshipper and the "infidel." This is that common ground where we may all grasp hands as brothers, united in mankind's common cause.

“Every individual is a unique manifestation of the Whole, as every branch is a particular outreaching of the tree. To manifest individuality, every branch must have a sensitive connection with the tree, just as our independently moving and differentiated fingers must have a sensitive connection with the whole body. The point, which can hardly be repeated too often, is that differentiation is not separation. The head and the feet are different, but not separate, and though man is not connected to the universe by exactly the same physical relation as branch to tree or feet to head, he is nonetheless connected—and by physical relations of fascinating complexity. The death of the individual is not disconnection but simply withdrawal. The corpse is like a footprint or an echo—the dissolving trace of something which the Self has ceased to do.”

“The fatwas reflect this belief in double standards. The differential attitude to conversion and apostasy illustrates this vividly. Islam regards it as a right and duty to convert persons from other religions. The ulema vehemently insist on it....Exactly the same position holds in regard to doing something or refraining from doing something out of regard for the other person’s religious sentiments.....An even more vivid instance is the stance in regard to the continuation of religious practices. It is the right and duty of a Muslim to carry on his religious rituals. ...Under no circumstances can the Islamic ruler give permission to kafirs to continue their religious rites, declares the Fatawa-i-Rizvia, and asks: shall he permit them to practise their kufr and thereby himself become a kafir?...It adds that there are several Hadis to the effect that no non-Muslim should remain in the Arab island...So, no non-Muslim shall be allowed to stay in the Arab island, but if a Bangladeshi who has entered India illegally is asked to leave, that is an assault on Islam!...Similarly, even today in no Islamic state can teachers in a school impart religious education of their faith to non-Muslim children...No restriction can be tolerated on teaching of the Quran and on religious instruction, declares Kifayatullah. ...And yet if we were to go by secularist discourse there is no religion which has abolished distinctions as Islam has, there is no religion which treats all equally as Islam does!”

“The philosophy of a purely theoretical thinker, who contemplates all things from the point of view of things in themselves, belongs in the same class as the attempt to apply abstract thought to the entire field of consciousness without meeting any byways or stops. Look at Baruch Spinoza, that true hero of thought, who studied in his own person the way in which the emotions and passions, as expressions of his internal mechanism, transform themselves for him into objects of geometrical analysis! In the meantime, until the heroism of Baruch Spinoza shall become the matter-of-fact virtue of everyday life in the higher developed humanity of the future, and until myths, poetry, metaphysics and religion shall no longer overshadow the field of consciousness, let us be content that up to now, and for the present, philosophy in its differentiated and its improved sense has served, and serves, as a critical instrument and helps science to keep its formal methods and logical processes clear; that it helps us in our lives to reduce the obstacles, which the fantastic projections of the emotions, passions, fears and hopes pile in the way of free thought; that it helps and serves, as Spinoza himself would say, to vanquish imaginationem et ignorantiam.”

“The cross is not random suffering, but necessary suffering. The cross is not suffering that stems from natural existence; it is the suffering that comes from being Christian. … A Christianity that no longer took discipleship seriously remade the gospel into only the solace of cheap grace. Moreover, it drew no line between natural and Christian existence. Such a Christianity had to understand the cross as one's daily misfortune, as the predicament and anxiety of our daily life. Here it has been forgotten that the cross also means being rejected, that the cross includes the shame of suffering. Being shunned, despised, and deserted by people, as in the psalmists unending lament, is an essential feature of the suffering of the cross, which cannot be comprehended by a Christianity that is unable to differentiate between a citizen's ordinary existence and a Christian existence. The cross is suffering with Christ.”
