“Had optical perception not evolved into something more than sensory perception, into super-sensory perception, then the present period would never have had the courage to discover the spiritual in matter. There would have been no fundamental difference between a painting by Picasso [from Picasso's so-called 'abstract' period] and one by Paulus Potter”

Theo van Doesburg (1883–1931) Dutch architect, painter, draughtsman and writer

Dutch painter from the 17th century, famous for his painting of cows

“I want a poetry that can learn as much from popular culture as from serious culture. A poetry that seeks the pleasure and emotionality of the popular arts without losing the precision, concentration, and depth that characterize high art. I want a literature that addresses a diverse audience distinguished for its intelligence, curiosity, and imagination rather than its professional credentials. I want a poetry that risks speaking to the fullness of our humanity, to our emotions as well as to our intellect, to our senses as well as our imagination and intuition. Finally I hope for a more sensual and physical art — closer to music, film, and painting than to philosophy or literary theory. Contemporary American literary culture has privileged the mind over the body. The soul has become embarrassed by the senses. Responding to poetry has become an exercise mainly in interpretation and analysis. Although poetry contains some of the most complex and sophisticated perceptions ever written down, it remains an essentially physical art tied to our senses of sound and sight. Yet, contemporary literary criticism consistently ignores the sheer sensuality of poetry and devotes its considerable energy to abstracting it into pure intellectualization. Intelligence is an irreplaceable element of poetry, but it needs to be vividly embodied in the physicality of language. We must — as artists, critics, and teachers — reclaim the essential sensuality of poetry. The art does not belong to apes or angels, but to us. We deserve art that speaks to us as complete human beings. Why settle for anything less?”

“God Himself is the nearest to hand, as the absolutely simple must be, and at the same time the most distant, as the absolutely simple must also be. God Himself is the irresolvable and at the same time that which fills and embraces everything else. God Himself in His being for Himself is the one being which stands in need of nothing else and at the same time the one being by which every thing else came into being and exists. God Himself is the beginning in which everything begins, with which we must and can always begin with confidence and without need of excuse. And at the same time He is the end in which everything legitimately and necessarily ends, with which we must end with confidence and without need of excuse. God Himself is simple, so simple that in all His glory He can be near to the simplest perception and also laugh at the most profound or acute thinking so simple that He reduces everyone to silence, and then allows and requires everyone boldly to make Him the object of their thought and speech. He is so simple that to think and speak correctly of Him and to live correctly before Him does not in fact require any special human complexities or for that matter any special human simplicities, so that occasionally and according to our need He may permit and require both human complexity and human simplicity, and occasionally they may both be forbidden us…”

“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.”

“But if some mind very different from ours were to look upon some property of some curved line as we do on the evenness of a straight line, he would not recognize as such the evenness of a straight line; nor would he arrange the elements of his geometry according to that very different system, and would investigate quite other relationships as I have suggested in my notes.
We fashion our geometry on the properties of a straight line because that seems to us to be the simplest of all. But really all lines that are continuous and of a uniform nature are just as simple as one another. Another kind of mind which might form an equally clear mental perception of some property of any one of these curves, as we do of the congruence of a straight line, might believe these curves to be the simplest of all, and from that property of these curves build up the elements of a very different geometry, referring all other curves to that one, just as we compare them to a straight line. Indeed, these minds, if they noticed and formed an extremely clear perception of some property of, say, the parabola, would not seek, as our geometers do, to rectify the parabola, they would endeavor, if one may coin the expression, to parabolify the straight line.”

“We are still spellbound by a tradition that arranged psychological faculties hierarchically, relegating ‘sensuousness’ — that is, perception — to a lower position in comparison to higher, reflective functions of reason and understanding. The most advanced versions of ‘conceptual art’ still follow this tradition. By refusing to base themselves in sensuously perceptible distinctions between works of art and other objects, these works seek to avoid reducing art to the realm of sense perception.”

“Interviewer: Is it possible to abolish man's humanity?
Levi: Unfortunately, yes. Unfortunately, yes; and that is really the characteristic of the Nazi lager [concentration camp]. About the others, I don't know, because I don't know them; perhaps in Russia the same thing happens. It's to abolish man's personality, inside and outside: not only of the prisoner, but also of the jailer. He too lost his personality in the lager.
These are two different itineraries, but with the same result, and I would say that only a few had the good fortune of remaining aware during their imprisonment; some regained their awareness of the experience later, but during it, they had lost it; many forgot everything. They did not record their experiences in their mind. They didn't impress on their memory track. Thus it happened to all, a profound modification in their personality. Most of all, our sensibility lost sharpness, so that the memories of our home had fallen into second place; the memory of family had fallen into second place in face of urgent needs, of hunger, of the necessity to protect oneself against cold, beatings, fatigue… all of this brought about some reactions which we could call animal-like; we were like work animals.
It is curious how this animal-like condition would repeat itself in language: in German there are two words for eating. One is essen and it refers to people, and the other is fressen, referring to animals. We say a horse frisst, for example, or a cat. In the lager, without anyone having decided that it should be so, the verb for eating was fressen. As if the perception of the animalesque regression was clear to all.”
