“Scientific Management is not a new "system," something "invented" by a man called F. W. Taylor, a passing novelty." It is something much deeper, an attitude towards the control of human systems of co-operation of all kinds rendered essential by the immense accretion of power over material things ushered in by the industrial revolution…
What Taylor did was not to invent something quite new, but to synthesise and present as a reasonably coherent whole ideas which had been germinating and gathering force in Great Britain and the United States throughout the nineteenth century. He gave to a disconnected series of initiatives and experiments a philosophy and a title; complete unity was not within his scope… It was left to others to extend his philosophy to other functions and especially to Henri Fayol, a Frenchman, to develop logical principles for the administration of a large-scale undertaking as a whole.
It detracts nothing from Taylor's greatness to see him thus as a man who focussed his thought of the preceding age, carried that thought forward with a group of friends and colleagues whose united contribution was so outstanding as to constitute a "golden age" of management in the United States and laid the intellectual foundations on which all subsequent work in Great Britain and many other countries has been based. But it is impossible to understand Taylor's achievement or the significance of Scientific Management for our society, unless his individual work is seen against the background of this larger whole of which it is only a part.”

“The whole system of symbolism impressed on the art and the life of the Middle Ages must awaken the admiration of poets in all times. In reality, what colossal unity there is in Christian art, especially in its architecture! These Gothic cathedrals, how harmoniously they accord with the worship of which they are the temples, and how the idea of the Church reveals itself in them! Everything about them strives upwards, everything transubstantiates itself; the stone buds forth into branches and foliage, and becomes a tree; the fruit of the vine and the ears of corn become blood and flesh; the man becomes God; God becomes a pure spirit. For the poet, the Christian life of the Middle Ages is a precious and inexhaustibly fruitful field. Only through Christianity could the circumstances of life combine to form such striking contrasts, such motley sorrow, such weird beauty, that one almost fancies such things can never have had any real existence, and that it is all a vast fever-dream the fever-dream of a delirious deity. Even Nature, during this sublime epoch of the Christian religion, seemed to have put on a fantastic disguise; for oftentimes though man, absorbed in abstract subtilties, turned away from her with abhorrence, she would recall him to her with a voice so mysteriously sweet, so terrible in its tenderness, so powerfully enchanting, that unconsciously he would listen and smile, and become terrified, and even fall sick unto death.”

“To show this later progress in my own work I refer to my [paintings] 'Organ-playing monk', in 1850, my 'Lord's Supper in the Geestes-kerk (church) in Utrecht' in 1852, and my 'Bakenesse-kerk (church) in Haarlem', painted a dozen years later. All three can be found in the museum Fodor and can thus be compared to each other. The preference will undoubtedly be given to the latter, which for its strength and unity is counted among the masterpieces of this [Fodor] collection.”

Johannes Bosboom (1817–1891) Dutch painter

version in original Dutch (citaat van Johannes Bosboom, in Nederlands): Om dien lateren vooruitgang in mijn eigen werk te toonen, verwijs ik naar mijn [werken] 'Orgelspelende monnik' in 1850, mijn 'Avondmaalsviering in de Geesteskerk te Utrecht' in 1852 en mijn 'Bakenessekerk te Haarlem', een tiental jaren later geschilderd - alle drie in het museum Fodor te vinden en dus onderling te vergelijken. De voorkeur zal ongetwijfeld aan het laatste worden toegekend, dat om zijn kracht en éénheid tot de meesterstukjes dezer verzameling gerekend wordt.

“The physical structures of organisms play only a minor and secondary role… The only requirement which physical structure must fulfill is that it allow the characteristic behaviors themselves to be manifested. Indeed, if this were not so, it would be impossible to understand how a class of systems as utterly diverse in physical structure as that which comprises biological organisms could be recognised as a unity at all.”

“This democratic method of resolving contradictions among the people was epitomized in 1942 in the formula “unity, criticism, unity”. To elaborate, it means starting from the desire for unity, resolving contradictions through criticism or struggle and arriving at a new unity on a new basis. In our experience this is the correct method of resolving contradictions among the people.”

“Then I gathered the éléments of what people call my symbolism. I do not understand anything about long words and theories. But I am willing to be a symbolist, if that defines the ideas that Michael Angelo gave me, namely that the essence of sculpture is the modelling, the general scheme which alone enables us to render the intensity, the supple variety of movement and character. If we can imagine the thought of God in creating the world, He thought first of the construction, which is the sole principle of nature, of living things and perhaps of the planets. Michael Angelo seems to me rather to derive from Donatello than from the ancients; Raphaël proceeds from them. He understood that an architecture can be built up with the human body, and that, in order to possess volume and harmony, a statue or a group ought to be contained in a cube, a pyramid or some simple figure. Let us look at a Dutch interior and at an interior painted by an artist of the present day. The latter no longer touches us, because it docs not possess the qualities of depth and volume, the science of distances. The artist who paints it does not know how to reproduce a cube. An interior by Van der Meer is a cubic painting. The atmosphere is in it and the exact volume of the objects; the place of these objects has been respected, the modem painter places them, arranges them as models. The Dutchmen did not touch them, but set themselves to render the distances that separated them, that is, the depth. And then, if I go so far as to say that cubic truth, not appearance, is the mistress of things, if I add that the sight of the plains and woods and country views gives me the principle of the plans that I employ on my statues, that I feel cubic truth everywhere, and that plan and volume appear to me as laws of all life and ail beauty, will it be said that I am a symbolist, that I generalise, that I am a metaphysician? It seems to me that I have remained a sculptor and a realist. Unity oppresses and haunts me.”

“And there you In a new embrace, with a new torrent of eternal love: all the elect, angels and men, from the last to the first are embraced It is a living and fruitful unity, which is the source and the fount of all life All creatures are there without themselves as in their eternal origin, One essence and one life with God These enlightened people are lifted up with free mind above reason…To the summit of their spirit Their naked understanding is penetrated with eternal clarity as the air is penetrated by the light of the sun. The bare elevated will is transformed and penetrated with fathomless love, just as iron is penetrated by the fire [God] gives Himself in the soul’s essence…Where the soul’s powers are unified…And undergo God’s transformation in simplicity. In this place all is full and overflowing, for the spirit feels itself as one truth and one richness. And one unity with God All spirits thus raised up Melt away and are annihilated by reason of enjoyment in God’s essence They fall away from themselves and are lost in a bottomless unknowingWith God they will ebb and flow, and will always be in repose…They are drunk with love and have passed away into God in a dark luminosity must accept that the Persons yield and lose themselves whirling in essential love, that is, in enjoyable unity; nevertheless, they always remain according to their personal properties In the working of the Trinity. You may thus understand that the divine nature is eternally at rest and without mode according to the simplicity of its essence. It is why all that God has chosen and enfolded with eternal personal love, he has possessed essentially, enjoyably in unity, with essential love.”

John Ruysbroeck (1293–1381) Flemish mystic

The Little Book of Enlightenment (c. 1364)

“Like Kant before him, Darwin insists that the source of all error is semblance. Analogy, he says again and again, is always a ‘deceitful guide’ (see pp. 61, 66, 473). As against analogy, or as I would say merely metaphorical characterizations of the facts, Darwin wishes to make a case for the existence of real ‘affinities’ genealogically construed. The establishment of these affinities will permit him to postulate the linkage of all living things to all others by the ‘laws’ or ‘principles’ of genealogical descent, variation, and natural selection. These laws and principles are the formal elements in his mechanistic explanation of why creatures are arranged in families in a time series. But this explanation could not be offered as long as the data remained encoded in the linguistic modes of either metaphor or synecdoche, the modes of qualitative connection. As long as creatures are classified in terms of either semblance or essential unity, the realm of organic things must remain either a chaos of arbitrarily affirmed connectedness or a hierarchy of higher and lower forms. Science as Darwin understood it, however, cannot deal in the categories of the ‘higher’ and ‘lower’ any more than it can deal in the categories of the ‘normal’ and ‘monstrous.’ Everything must be entertained as what it manifestly seems to be. Nothing can be regarded as ‘surprising,’ any more than anything can be regarded as ‘miraculous.”

“.. can you [contemporary painters] ever get close, even vaguely, to the solidity, the transparency, the lyric strength of colour, to the clarity, the mystery, the emotion of any of the paintings of Fra Angelico, Piero della Francesca, Botticelli, Dürer, Holbein or of young Raphael? Friends, have you ever realized that with the oil colours used today this is absolutely impossible?... In the museums of Europe I have observed the work of the Flemish painters at length – those earlier, later as well as contemporary to the [brothers] Van Eycks – and I am convinced that the above mentioned brothers were not the discoverers of oil paint in its true sense, as is held today, but that what they did was introduce oil in emulsion with other substances, especially live and fossil resins, into so-called oil tempera emulsion, which was already known in the Flanders, to enable them through the use of veiling to give a greater finish, cleanliness and strength of colour to their painting.
'These oils which are their tempera' said Vasari, speaking of the Flemish [painters] in his Life of Antonello; and without doubt he was alluding to Flemish oil tempera emulsion, but it is sure, absolutely sure, that.... we are dealing with.... a tempera based mixture (egg, glue, resin, tempera etc) in which oil was only used as a means of unity and for the finish of the painting.”

“We cannot avoid conflict, conflict with society, other individuals and with oneself.

“I think of the good, decent, peace-loving people I have known by the thousands, and I wonder. How many of them are so afflicted with the wasting disease of normalcy that, even as they declare for the peace, their hands reach out with an instinctive spasm… in the direction of their comforts, their home, their security, their income, their future, their plans—that five-year plan of studies, that ten-year plan of professional status, that twenty-year plan of family growth and unity, that fifty-year plan of decent life and honorable natural demise. “Of course, let us have the peace,” we cry, “but at the same time let us have normalcy, let us lose nothing, let our lives stand intact, let us know neither prison nor ill repute nor disruption of ties.” And because we must encompass this and protect that, and because at all costs—at all costs—our hopes must march on schedule, and because it is unheard of that in the name of peace a sword should fall, disjoining that fine and cunning web that our lives have woven, because it is unheard of that good men should suffer injustice or families be sundered or good repute be lost—because of this we cry peace and cry peace, and there is no peace. There is no peace because there are no peacemakers. There are no makers of peace because the making of peace is at least as costly as the making of war—at least as exigent, at least as disruptive, at least as liable to bring disgrace and prison and death in its wake.”

“That I started [in the creation of his art] from my immediate environment was extremely important to me. Only the things I knew, with which I was familiar, which I had caught on their reality value, I could approach free of extra-pictorial aesthetics and pale romanticism. Of course the question remained how I - who wanted to involve modern life in my art - could continue to seek my inspiration at Machelen-aan-de-Leie, a village in the countryside, far from the city and the crowds. Where can one sense better the infiltration of modern life than in a village in the countryside? In the city everything gets integrated immediately, you can't see clearly the insulating and contrasting-alienating effect of publicity, the gas-station, the concrete, the car, etc. On the other hand, I keep saying that we must continue to see the grass, the corn and the cows. Not within an animistic unity, but from a mentality that has the courage to approach these things freely and ruthless in our era. What ordinary people make out of life is fascinating me.”

Roger Raveel (1921–2013) painter

Dat ik [met het maken van mijn kunst] vertrok uit mijn onmiddellijke omgeving vond ik uiterst belangrijk. Alleen de dingen die ik kende, waarmee ik vertrouwd was, die ik op hun werkelijkheidswaarde had betrapt konden vrij van extra-picturale esthetiek en van bleek romantisme door mij benaderd worden. De vraag bleef natuurlijk hoe ik, die het moderne leven in mijn kunst wou betrekken, mijn inspiratie kon blijven zoeken te Machelen-aan-de-Leie, een dorp op het platteland, ver van de stad en van de drukte. Waar kan men beter het infiltreren van het moderne leven gewaar worden dan in een dorp op het platteland? In de stad wordt alles onmiddellijk geïntegreerd, ziet men niet zo scherp de isolerende en tevens contrasterend-bevreemdende werking van de publiciteit, het benzinestation, het beton, de auto, enz. Aan de andere kant blijf ik ervan overtuigd dat ook het gras, het koren en de koe nog moeten gezien worden. Niet binnen een animistische eenheid, maar wel vanuit een mentaliteit die vrij en meedogenloos deze dingen in ons tijdperk nog zou durven benaderen. Wat de gewone man van het leven maakt, dat boeit mij.
