“If the progressing rationality of advanced industrial society tends to liquidate, as an “irrational rest,” the disturbing elements of Time and Memory, it also tends to liquidate the disturbing rationality contained in this irrational rest. Recognition and relation to the past as present counteracts the functionalization of thought by and in the established reality. It militates against the closing of the universe of discourse and behavior it renders possible the development of concepts which destabilize and transcend the closed universe by comprehending it as historical universe. Confronted with the given society as object of its reflection, critical thought becomes historical consciousness as such, it is essentially judgment. Far from necessitating an indifferent relativism, it searches in the real history of man for the criteria of truth and falsehood, progress and regression. The mediation of the past with the present discovers the factors which made the facts, which determined the war of life, which established the masters and the servants; it projects the limits and the alternatives. When this critical consciousness speaks, it speaks “le langage de la connaissance” (Roland Barthes) which breaks open a closed universe of discourse and its petrified structure. The key terms of this language are not hypnotic nouns which evoke endlessly the same frozen predicates. They rather allow of an open development; they even unfold their content in contradictory predicates. The Communist Manifesto provides a classical example. Here the two key terms, Bourgeoisie and Proletariat, each “govern” contrary predicates. The “bourgeoisie” is the subject of technical progress, liberation, conquest of nature, creation of social wealth, and of the perversion and destruction of these achievements. Similarly, the "proletariat” carries the attributes of total oppression and of the total defeat of oppression. Such dialectical relation of opposites in and by the proposition is rendered possible by the recognition of the subject as an historical agent whose identity constitutes itself in and against its historical practice, in and against its social reality. The discourse develops and states the conflict between the thing and its function, and this conflict finds linguistic expression in sentences which join contradictory predicates in a logical unit—conceptual counterpart of the objective reality. In contrast to all Orwellian language, the contradiction is demonstrated, made explicit, explained, and denounced.”

“The Protestant churches generally hold that the elements of the sacrament are flesh and blood only in a tropical sense; they nourish our souls as meat and the juice of it would our bodies. But the Catholics maintain that they are literally just that; although they possess all the sensible qualities of wafer-cakes and diluted wine. But we can have no conception of wine except what may enter into a belief, either —
# That this, that, or the other, is wine; or,
# That wine possesses certain properties.
Such beliefs are nothing but self-notifications that we should, upon occasion, act in regard to such things as we believe to be wine according to the qualities which we believe wine to possess. The occasion of such action would be some sensible perception, the motive of it to produce some sensible result. Thus our action has exclusive reference to what affects the senses, our habit has the same bearing as our action, our belief the same as our habit, our conception the same as our belief; and we can consequently mean nothing by wine but what has certain effects, direct or indirect, upon our senses; and to talk of something as having all the sensible characters of wine, yet being in reality blood, is senseless jargon. Now, it is not my object to pursue the theological question; and having used it as a logical example I drop it, without caring to anticipate the theologian's reply. I only desire to point out how impossible it is that we should have an idea in our minds which relates to anything but conceived sensible effects of things. Our idea of anything is our idea of its sensible effects; and if we fancy that we have any other we deceive ourselves, and mistake a mere sensation accompanying the thought for a part of the thought itself. It is absurd to say that thought has any meaning unrelated to its only function. It is foolish for Catholics and Protestants to fancy themselves in disagreement about the elements of the sacrament, if they agree in regard to all their sensible effects, here or hereafter.
It appears, then, that the rule for attaining the third grade of clearness of apprehension is as follows: Consider what effects, which might conceivably have practical bearings, we conceive the object of our conception to have. Then, our conception of these effects is the whole of our conception of the object.”

Charles Sanders Peirce (1839–1914) American philosopher, logician, mathematician, and scientist

“It is at any rate evident, that a large and ample province remains for the exercise of Providence, without its being naturally perceptible by us; because obscurity, when applied to the interruption of laws, bears a necessary proportion to the imperfection of our knowledge when applied to the laws themselves, or rather to the effects which these laws, under their various and incalculable combinations, would of their own accord produce. And if it be said, that the doctrine of Divine Providence, by reason of the ambiguity under which its exertions present themselves, can be attended with no practical influenceupon our conduct; that, although we believe ever so firmly that there is a Providence, we must prepare, and provide, and act, as if there were none; I answer, that this is admitted: and that we further allege, that so to prepare, and so to provide, is consistent with the most perfect assurance of the reality of a Providence; and not only so, but that it is probably one advantage of the present state of our information, that our provisions and preparations are not disturbed by it. Or if it be still asked, Of what use at all then is the doctrine, if it neither alter our measures nor regulate our conduct? I answer again, that it is of the greatest use, but that it is a doctrine of sentiment and piety, not (immediately at least) of action or conduct; that it applies to the consolation of men's minds, to their devotions, to the excitement of gratitude, the support of patience, the keeping alive and the strengthening of every motive for endeavouring to please our Maker; and that these are great uses.”

“Process-chart notes and information should be collected and set down in sketch form by a highly intelligent man, preferably with an engineering training and experience, but who need not necessarily have been previously familiar with the actual details of the processes. In fact, the unbiased eye of an intelligent and experienced process-chart maker usually brings better results than does the study of a less keen man with more special information regarding present practices of the processes. The mere act of investigating sufficiently to make the notes in good enough condition for the draftsman to copy invariably results in many ideas and suggestions for improvement, and all of these suggestions, good and bad, should be retained and filed together with the description of the process chart. These suggestions and proposed improvements must be later explained to others, such as boards of directors, managers and foremen, and for best results also to certain workmen and clerks who have special craft or process knowledge. To overcome the obstacles due to habit, worship of tradition and prejudice, the more intelligence shown by the process-chart recorder, the sooner hearty cooperation of all concerned will be secured. Anyone can make this form of process chart with no previous experience in making such charts, but the more experience one has in making them, the more certain standard combinations of operations, inspection and transporting can be transferred bodily to advantage to the charts of proposed processes.”

Firuz Shah Tughlaq photo

“Firuz Shah Tughlaq organised an industry out of catching slaves. Shams-i-Siraj Afif writes in his Tarikh-i-Firuz Shahi: “The Sultan commanded his great fief-holders and officers to capture slaves whenever they were at war (that is, suppressing Hindu rebellions), and to pick out and send the best for the service of the court. The chiefs and officers naturally exerted themselves in procuring more and more slaves and a great number of them were thus collected. When they were found to be in excess, the Sultan sent them to important cities… It has been estimated that in the city and in the various fiefs, there were 1,80,000 slaves… The Sultan created a separate department with a number of officers for administering the affairs of these slaves.”. Firuz Shah beat all previous records in his treatment of the Hindus… He records another instance in which Hindus who had built new temples were butchered before the gate of his palace, and their books, images, and vessels of Worship were publicly burnt. According to him “this was a warning to all men that no zimmi could follow such wicked practices in a Musulman country”. Afif reports yet another case in which a Brahmin of Delhi was accused of “publicly performing idol-worship in his house and perverting Mohammedan women leading them to become infidels”. The Brahmin “was tied hand and foot and cast into a burning pile of faggots.””

Firuz Shah Tughlaq (1309–1388) Tughluq sultan

The historian who witnessed this scene himself expresses his satisfaction by saying, “Behold the Sultan’s strict adherence to law and rectitude, how he would not deviate in the least from its decrees.”

“Every evening after dinner, a new life began. There was no hurry. Some walked in the garden. Others smoked. About nine o’clock we made our way alone or in twos and threes to the Study House. Outdoor shoes came off and soft shoes or moccasins were put on. We sat quietly, each on his or her own cushion, round the floor in the centre. Men sat on the right, women on the left; never together.

Some went straight on to the stage and began to practice the rhythmic exercises. On our first arrival, each of us had the right to choose his own teacher for the movements. I had chosen Vasili Ferapontoff, a young Russian, tall, with a sad studious face. He wore pince-nez, and looked the picture of the perpetual student, Trofimov, in The Cherry Orchard. He was a conscientious instructor, though not a brilliant performer. I came to value his friendship, which continued until his premature death ten years later. He told me in one of our first conversations that he expected to die young.

The exercises were much the same as those I had seen in Constantinople three years before. The new pupils, such as myself, began with the series called Six Obligatory Exercises. I found them immensely exciting, and worked hard to master them quickly so that I could join in the work of the general class.”

“In the spring of 1920, General Motors found itself, as it appeared at the moment, in a good position. On account of the limitation of automotive production during the war there was a great shortage of cars. Every car that could be produced was produced and could be sold at almost any price. So far as any one could see, there was no reason why that prosperity should not continue for a time at least. I liken our position then to a big ship in the ocean. We were sailing along at full speed, the sun was shining, and there was no cloud in the sky that would indicate an approaching storm. Many of you have, of course, crossed the ocean and you can visualize just that sort of a picture yet what happened? In September of that year, almost over night, values commenced to fall. The liquidation from the inflated prices resulting from the war had set in. Practically all schedules or a large part of them were cancelled. Inventory commenced to roll in, and, before it was realized what was happening, this great ship of ours was in the midst of a terrific storm. As a matter of fact, before control could be obtained General Motors found itself in a position of having to go to its bankers for loans aggregating $80,000,000 and although, as we look at things from today's standpoint, that isn't such a very large amount of money, yet when you must have $80,000,000 and haven't got it, it becomes an enormous sum of money, and if we had not had the confidence and support of the strongest banking interests our ship could never have weathered the storm.”

“And this [experimental] science verifies all natural and man-made things in particular, and in their appropriate discipline, by the experimental perfection, not by arguments of the still purely speculative sciences, nor through the weak, and imperfect experiences of practical knowledge. And therefore, this is the matron of all preceding sciences, and the final end of all speculation.”
Et hæc scientia certificat omnia naturalia et artificialia in particulari et in propria disciplina, per experientiam perfectam; non per argumenta, ut scientiæ pure speculativae, nec per debiles et imperfecta experientias ut scientiae operativæ.

“Zionism as a colonial movement is constituted in ideology and practice by a religio-racial epistemology through which it apprehends itself and the world around it. This religioracial grid informs and is informed by its colonial-settler venture. The colonial model remains the best model through which Zionism should be analyzed, but it is important also to analyze the racial dimension of Zionism in its current manifestation, which is often elided.”
