“If a man is to be a man, a free spirit unto himself, he must arm himself not only with weapons but with ideals and concepts he is willing to die for.”

“The Principle of Uncertainty is a bad name. In science, or outside of it, we are not uncertain; our knowledge is merely confined, within a certain tolerance. We should call it the Principle of Tolerance. And I propose that name in two senses. First, in the engineering sense: Science has progressed, step by step, the most successful enterprise in the ascent of man, because it has understood that the exchange of information between man and nature, and man and man, can only take place with a certain tolerance. But second, I also use the word, passionately, about the real world. All knowledge – all information between human beings – can only be exchanged within a play of tolerance. And that is true whether the exchange is in science, or in literature, or in religion, or in politics, or in any form of thought that aspires to dogma. It's a major tragedy of my lifetime and yours that scientists were refining, to the most exquisite precision, the Principle of Tolerance – and turning their backs on the fact that all around them, tolerance was crashing to the ground beyond repair. The Principle of Uncertainty or, in my phrase, the Principle of Tolerance, fixed once for all the realization that all knowledge is limited. It is an irony of history that at the very time when this was being worked out, there should rise, under Hitler in Germany and other tyrants elsewhere, a counter-conception: a principle of monstrous certainty. When the future looks back on the 1930's, it will think of them as a crucial confrontation of culture as I have been expounding it – the ascent of man against the throwback to the despots' belief that they have absolute certainty.”

Episode 11: "Knowledge or Certainty"
The Ascent of Man (1973)

“The ultimate "causes of price" - to use a Classical term - lie deeply embedded in the psychology and techniques of mankind and his environment, and are as manifold as the sands of the sea. All economic analysis is an attempt to classify these manifold causes, to sort them out into categories of discourse that our limited minds can handle, and so to perceive the unity of structural relationship which both unites and separates the manifoldness. Our concepts of "" and "supply" are such broad categories. In whatever sense they are used, they are not ultimate determinants of anything, but they are convenient channels through which we can classify and describe the effects of the multitude of determinants of the system of economic magnitude.”

Kenneth E. Boulding (1910–1993) British-American economist

Winter 2003–4, Vol. 26, No. 2. 323 commented on this article, saying: "Boulding (1944) argued that if liquidity preference were divorced from the "demand for money," the former could come into its own as a theory of financial asset pricing. According to this view, rising liquidity preference or a "wave of bearish sentiment" is manifest in a shift from certain asset categories, specifically, those that are characterized by high capital uncertainty (that is, uncertainty about the future value of the asset as a result of market revaluation) to assets such as commercial paper or giltedged securities."

“[Ackoff also developed the circular organization concept. This structure is a democratic hierarchy with three essential characteristics:]
(1) the absence of an ultimate authority, the circularity of power;
(2) the ability of each member to participate directly or through representation in all decisions that affect him or her directly; and
(3) the ability of members, individually or collectively, to make and implement decisions that affect no one other than the decision maker or decision-makers.”

“The Christianity of the first centuries recognized as productions of good art, only legends, lives of saints, sermons, prayers, and hymn-singing evoking love of Christ, emotion at his life, desire to follow his example, renunciation of worldly life, humility, and the love of others; all productions transmitting feelings of personal enjoyment they considered to be bad, and therefore rejected … This was so among the Christians of the first centuries who accepted Christ teachings, if not quite in its true form, at least not yet in the perverted, paganized form in which it was accepted subsequently.
But besides this Christianity, from the time of the wholesale conversion of whole nations by order of the authorities, as in the days of Constantine, Charlemagne and Vladimir, there appeared another, a Church Christianity, which was nearer to paganism than to Christ's teaching. And this Church Christianity … did not acknowledge the fundamental and essential positions of true Christianity — the direct relationship of each individual to the Father, the consequent brotherhood and equality of all people, and the substitution of humility and love in place of every kind of violence — but, on the contrary, having founded a heavenly hierarchy similar to the pagan mythology, and having introduced the worship of Christ, of the Virgin, of angels, of apostles, of saints, and of martyrs, but not only of these divinities themselves but of their images, it made blind faith in its ordinances an essential point of its teachings.
However foreign this teaching may have been to true Christianity, however degraded, not only in comparison with true Christianity, but even with the life-conception of the Romans such as Julian and others, it was for all that, to the barbarians who accepted it, a higher doctrine than their former adoration of gods, heroes, and good and bad spirits. And therefore this teaching was a religion to them, and on the basis of that religion the art of the time was assessed. And art transmitting pious adoration of the Virgin, Jesus, the saints, and the angels, a blind faith in and submission to the Church, fear of torments and hope of blessedness in a life beyond the grave, was considered good; all art opposed to this was considered bad.”

“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.”

“As an instance of the remarkably far-reaching effect which a single mathematico-physical concept has had upon the development of chemical theory, one has but to recall the state of chemistry just before the revival of Avogadro's law by Cannizzaro, to be impressed by its confusion.”

J. R. Partington (1886–1965) British chemist

Introduction
Higher Mathematics for Chemical Students (1911)
Context: As an instance of the remarkably far-reaching effect which a single mathematico-physical concept has had upon the development of chemical theory, one has but to recall the state of chemistry just before the revival of Avogadro's law by Cannizzaro, to be impressed by its confusion. Relying solely upon their "chemical instinct," the leaders of the various schools of chemical thought had developed each his own theoretical system.... a host of... conceptions strove for supremacy. The strife was stilled, order and unity were restored, as soon as Avogadro's great idea was seen in its true light, and the concept of the molecule was introduced into chemistry. A formula which had required pages of reasoning from a purely chemical standpoint to establish, and that insecurely, was fixed by a single numerical result.

“First there are the Jews who, dwelling in every country throughout the world, identify themselves with that country, enter into its national life and, while adhering faithfully to their own religion, regard themselves as citizens in the fullest sense of the State which has received them. Such a Jew living in England would say, 'I am an English man practising the Jewish faith.' This is a worthy conception, and useful in the highest degree. We in Great Britain well know that during the great struggle the influence of what may be called the 'National Jews' in many lands was cast preponderatingly on the side of the Allies; and in our own Army Jewish soldiers have played a most distinguished part, some rising to the command of armies, others winning the Victoria Cross for valour. There is no need to exaggerate the part played in the creation of Bolshevism and in the actual bringing about of the Russian Revolution, by these international and for the most part atheistical Jews, it is certainly a very great one; it probably outweighs all others. With the notable exception of Lenin, the majority of the leading figures are Jews. Moreover, the principal inspiration and driving power comes from the Jewish leaders. Thus Tchitcherin, a pure Russian, is eclipsed by his nominal subordinate Litvinoff, and the influence of Russians like Bukharin or Lunacharski cannot be compared with the power of Trotsky, or of Zinovieff, the Dictator of the Red Citadel (Petrograd) or of Krassin or Radek -- all Jews. In the Soviet institutions the predominance of Jews is even more astonishing. And the prominent, if not indeed the principal, part in the system of terrorism applied by the Extraordinary Commissions for Combating Counter-Revolution has been taken by Jews, and in some notable cases by Jewesses. The same evil prominence was obtained by Jews in the brief period of terror during which Bela Kun ruled in Hungary. The same phenomenon has been presented in Germany (especially in Bavaria), so far as this madness has been allowed to prey upon the temporary prostration of the German people. Although in all these countries there are many non-Jews every whit as bad as the worst of the Jewish revolutionaries, the part played by the latter in proportion to their numbers in the population is astonishing.”

“In vain do individual great men seek to mint new concepts and to set them in circulation — it is pointless. They are used for only a moment, and not by many, either, and they merely contribute to making the confusion even worse, for one idea seems to have become the fixed idea of the age: to get the better of one's superior. If the past may be charged with a certain indolent self-satisfaction in rejoicing over what it had, it would indeed be a shame to make the same charge against the present age (the minuet of the past and the gallop of the present). Under a curious delusion, the one cries out incessantly that he has surpassed the other, just as the Copenhageners, with philosophic visage, go out to Dyrehausen "in order to see and observe," without remembering that they themselves become objects for the others, who have also gone out simply to see and observe. Thus there is the continuous leap-frogging of one over the other — "on the basis of the immanent negativity of the concept", as I heard a Hegelian say recently, when he pressed my hand and made a run preliminary to jumping. — When I see someone energetically walking along the street, I am certain that his joyous shout, "I am coming over," is to me — but unfortunately I did not hear who was called (this actually happened); I will leave a blank for the name, so everyone can fill in an appropriate name.”

“Kapila's arguments are listed [by Dr. Ambedkar], and the last one introduces yet another fundamental concept of Buddhism: suffering (dukkha). It is brought in from an unusual angle: 'Kapila argued that the process of development of the unevolved is through the activities of three constituents of which it is made up, Sattva, Rajas and Tamas. These are called three Gunas. [Sattva is] light in nature, which reveals, which causes pleasure to men; [Rajas is] what impels and moves, what produces activity; [Tamas is] what is heavy and puts under restraint, what produces the state of indifference or inactivity (') When the three Gunas are in perfect balance, none overpowering the other, the universe appears static (achetan) and ceases to evolve. When the three Gunas are not in balance, one overpowers the other, the universe becomes dynamic (sachetan) and evolution begins. Asked why the Gunas become unbalanced, the answer which Kapila gave was that this disturbance in the balance of the three Gunas was due to the presence of Dukkha (suffering).”

Buddhism is quite close to the Samkhya-Yoga viewpoint: to Samkhya for its philosophical framework, to Yoga for its methods of meditation.
