"Differentiation" Quotes from Famous Books



... all peoples have had philosophies consisting of their accepted explanation of things. Such a philosophy must necessarily result from the primary instincts developed in man in the early progress of his differentiation from the beast. This I postulate: if demonstration is necessary, demonstration is at hand. Not only has every people a philosophy, but every stage of culture is characterized by its stage of philosophy. Philosophy has been ...

... instance, of the Bacchanal orgies. The votary of Dionysus, dancing, shrieking, tearing at his hair and at his garments, lost in the lightning change of his sensations all power of relating them. His mind was ringed in a whirling circle, every point of which merged into the next without possibility of differentiation. And since he could feel no transition periods, he could feel HIMSELF no longer; he was one with the content of his consciousness, which consciousness was no less a unit than our bright light aforesaid, just as a circle is as ...

... discern in every question is the familiar obvious, and it came as a great and shattering discovery to the economic and sociological thought of the latter half of the nineteenth century that there was going on not simply a production but an immense concentration of wealth, a differentiation of a special wealthy class of landholder and capitalist, a diminution of small property owners and the development of a great and growing class of landless, nearly propertyless men, the proletariat. Marx showed—he showed so clearly that to-day it is recognized by every intelligent ...

... allegiance. Proportional representation and preferential voting I have mentioned. The short ballot is a psychological principle which must be taken into account wherever there is voting: it will help the differentiation of political groups by concentrating the attention on essential choices. The recall of public officials is in part a policeman's club, in part a clumsy way of getting around the American prejudice for a fixed term of office.

... in that particular social formation?—though we must also consider how these different types act and react, how they combine with, transform, subjugate, ruin or replace each other in region after region. We thus re-interpret the vicissitudes of history in more general terms, those of the differentiation, progress or degeneracy of each occupational and social type, and the ascending and descending oscillations of these types. In short, these occupational struggles underlie and largely interpret even the conflict of races, upon which Mr. Stuart-Glennie and other sociologists have so ...

Assuming that conditions which permit genetic exchange between populations of turtles in the Salado drainage system differ in no major respect from conditions in other parts of the range of Pseudemys scripta, it is logical to suppose that the differentiation of P. s. taylori at Cuatro Cienegas was preceded by the isolation of a population in ...

... unknown in China. Ancestor-worship, also, survives in many other races as one of the main cults, even after other elements of later religion have been superimposed upon it. In Greece and Rome it remained to the last an important part of domestic ritual. But in most cases a gradual differentiation is set up in time between various classes of ghosts or dead persons, some ghosts being considered of more importance and power than others; and out of these last it is that gods as a rule are finally developed. A god, in fact, is in the beginning, at least, ...

The uniformity of the spirit world, which is the characteristic trait of primitive Animism, gave way to a differentiation regulated by the political development and the social growth of Babylonia. The more important natural forces became gods, and the inferior ones were, as a general thing, relegated to the secondary position of mere sprites, ...

He has no labor saving or labor multiplying machines. There is but little differentiation of function in either family or tribe. Each worker does all kinds of work.

As to how many of these succumb, not to the venom, but to the misdirected efforts of misguided friends at treatment—an extremely important differentiation—he lacks the data upon which to base a reckoning.

On the side of civil administration and education, the functions of the Druids, as the successors of the primitive medicine men and magicians, doubtless varied greatly in different parts of Gaul and Britain according to the progress that had been made in the differentiation of functions in social life.

But here, it seems to me, we must make a clear differentiation.

... activities of the diverse human units that make it up. The farmer, the manufacturer, the soldier, clerk, and artisan do not all work in the same way; they undertake one or another of the economic tasks which they may be best fitted by circumstances to perform. Their differentiation and division of labor are identical with the diversity in structure and in function as well, exhibited by the cells of a living creature.

Some scholars have explained it as a negative particle, others as a demonstrative pronoun; others, again, took it as a mere symbol of differentiation. If the last explanation could be established by more general analogies, then, no doubt, we should have here an inflection, that cannot be referred to combination.

... in the womb of her that is with child." Life itself is insusceptible of any definition which satisfies, but we know that we live, nevertheless. Science points out a common origin in protoplasmic cells and is quite unable to explain so common a fact as sex differentiation.

Why, therefore, should the Incarnation be thought incredible or impossible because it does not come within the limitations ...

... [dialectics], and this knowledge alone constitutes his true existence."[48] This life-process of the Absolute has three "moments." It may be considered as the idea in itself—bare, naked, undetermined, unconscious idea; as the idea out of itself, in its objective form, or in its differentiation; and, finally, as the idea in itself, and for itself, in its regressive or reflective form. This movement of thought gives, first, bare, naked, indeterminate thought, or thought in the mere antithesis of Being and non-Being; secondly, thought externalizing ...

These facts all point to the same general conclusion, namely, that good is derived ...

But there can be little doubt that the practice of mummification gave greater definiteness to the ideas regarding the "heart" and "breath," which eventually led to a differentiation between their supposed functions.[69] As the heart and the blood were obviously present in the dead body they could no longer be regarded as the "life". The breath was clearly the "element" the lack of which rendered the body inanimate. It was therefore regarded as necessary to set the heart ...

The differentiation that thus arose between the dwelling-place of the god and the place where he was to be worshipped is a perfectly natural one.

There are obvious reasons, in the centralisation of vast industrial interests, the "integration," as Mr. Spencer calls it, which is the correlative of differentiation, in the growing solidarity of different classes and countries, in the consequent growth of natural monopolies, which give a solid reason for believing that the functions of the central government may require expansion.

This was also a survival of galley warfare, and rapidly disappeared with the advance of the sailing man-of-war, never to be revived, unless perhaps it be ...

... rigorous adherence to the original in the transference of facts from a narrative to a drama. To this adherence are due certain features which any one not fresh from reading the account in Samuel might easily attribute to the dramatist's skill—the differentiation of the characters, the varying moods of joy, sorrow, indignation, hope and despair, besides the unusual vigour of some of the scenes. Dramatic art, however, is frequently as severely tested in an author's selection of a subject as in his invention of one. From this test Peele's talent would have ...

In Germany his later speeches, in which he drew a distinction between the German people and the Imperial Government, were regarded as hypocrisy.

The question has, however, never been answered why this distinction ...

In looking over the literature of this subject, which is now copious, it is interesting to observe the differentiation of minds, and to single out those who went by a kind of instinct to the core of the question, from those who erred in it, or who learnedly occupied themselves with its analogies, adjuncts, and details.

No foreigner really capable of estimating the conditions could have seriously entertained any hope of a rapprochement. The barriers of racial feeling, of emotional differentiation, of language, of manners and beliefs, are likely to remain insurmountable for centuries. Though instances of warm friendship, due to the mutual attraction of exceptional natures able to divine each other intuitively, might be cited, the foreigner, as a general rule, understands the Japanese ...

... multitudes dulled by mindless labour and enervated by the tradition of two hundred years of servile security against multitudes demoralised by lives of venial privilege and sensual indulgence. They had no artillery, no differentiation into this force or that; the only weapon on either side was the little green metal carbine, whose secret manufacture and sudden distribution in enormous quantities had been one of Ostrog's culminating ...

... Empire of the East, a second with France, a third with Spain. The North is overshadowed by Germany; the South is disquieted by Islam. The types thus formed and thus discriminated are vital, and persist for centuries with the tenacity of physical growths. Each differentiation owes its origin to causes deeply rooted in the locality. The freedom and apparent waywardness of nature, when she sets about to form crystals of varying shapes and colors, that shall last and bear her stamp for ever, have governed their uprising ...

... protoplasm when living; and living protoplasm, again, may be either animal or vegetable. Both are in every respect (externally) absolutely identical. Yet the one will only develop into a plant, the other only into an animal. Nor does it diminish the significance of the fact to say that the differentiation is now fixed by heredity. If we suppose protoplasm to be only a fortuitous combination of elements, what secondary or common natural cause will account for its acquisition of the fixed difference? It is true that some ...

... preparatory department has been maintained in many colleges. The present aim and tendency of our educational system is to introduce the pupil from the high school to the rank of Freshman in college. This condition can not become general unless there be a greater differentiation in the courses of study in our high schools. It is encouraging to see that in many States the high schools, academies and colleges are coming to a helpful understanding of each other's province, and that there is a practical ...

... perhaps is even possible, when the question is whether two kingdoms such as the Articulata or Mollusca are the highest. Within the same kingdom I am inclined to think that "highest" usually means that form which has undergone most "morphological differentiation" from the common embryo or archetype of the class; but then every now and then one is bothered (as Milne Edwards has remarked) by "retrograde development," i.e., the mature animal having fewer and less important organs than its own embryo. ...

... the spring of 1906 the Government decided to appoint a strong Committee to inquire into the questions of graduation and differentiation of the income tax, which had for some Sessions been coming into prominence in consequence of the financial difficulties caused by the South African War.

... Medicine (cf. Rashdall, vol. i. p. 9). But the title might still be adopted at will by ambitious schools, and the intervention of the great potentates of Europe was required to provide a mechanism for the differentiation of General from Particular Studia. Already, in the twelfth century, an Emperor and a Pope had given special privileges to students at Bologna and other Lombard towns, and a King of France had conferred privileges upon the scholars of Paris. In 1224 the Studium Generale of Naples was founded ...

... perception in modern music may be roughly divided into three steps: First, the recognition of consonance, especially of the most fruitful consonance of all—that of the thirds, and the differentiation between consonance and dissonance. A second step involved the recognition of dissonance as an element in musical expression, on account of the motion it imparts to a harmonic movement. Third, the establishment of these materials ...

... the ashes of the nationalised banking business. These institutions would make themselves responsible for the lending side of banking, and would obviously, and naturally, be allowed to make a profit on this side of the business. In this differentiation Mr Webb's ingenuity is seen at its very best. He reserves for the State that part of banking which is purely a matter of routine, and he leaves to private enterprise that part of it which requiries the elasticity and judgment and quickness ...

... forms of action became largely unintelligible and significatory only after long experience. It became, moreover, differently differentiated with each individual, and hence still more difficult to understand. How far this differentiation may go when it has endured generation after generation and is at last crystallized into a set type, is well known; just as by training the muscles of porters, tumblers or fencers develop in each individual, so the muscles develop in those portions of our body most animated by the mind—in ...

Farther on he shows a like coincidence between the development of the system of fins in the different groups of fishes, and the gradual growth and differentiation of the fins in the embryo of the higher living fishes.* (* "Recherches sur les Poissons Fossiles", volume 1 chapter 5 page 102.)

There are at least two considerations which must be borne in mind in connection with these schedules. The first is, that all the marriages described as unlimited may not have been so. I do not suggest that the answers are intentionally false, ...

This form by reason of its simplicity and directness is often found in the short pianoforte pieces of Schumann, Tchaikowsky, Brahms, Grieg and Debussy. For a long period there was no attempt at differentiation between vocal and instrumental style; music, in fact, during the 15th and 16th centuries was often entitled "buon da cantare ou suonare," i.e., equally well suited for voices or instruments. When instrumental players were in search of pieces, ...

... before the powerful impulse that started from Cohnheim, bore fruit for clinical histology. As we have mentioned this was due to the circumstance that an exact differentiation of the various forms of leucocytes was very difficult with the methods in use up to that time. Although such distinguished observers as Wharton Jones and Max Schultze had been able to distinguish different types of leucocytes, Cohnheim's work remained clinically fruitless since the criteria they ...

Towards 1500, European nations, having been fashioned and composed out of simple elements during the thousand years between the fall of the Roman Empire and that of its successor is the East, had reached full measure of differentiation. They were estranged from each other, and were inclined to treat the foreigner as the foe. Ancient links were loosened, the Pope was no longer an accepted peacemaker; and the idea of an international code, overriding the will of nations and the authority ...

But the differentiation between Irish, Welsh, Scotch, Scotch-Irish, and English names is infinitely more difficult. The Scotch-Irish particularly have challenged the conclusions reached by the Census Bureau. They claim a much larger proportion of the original bulk of ...

... the power of production increased, owing to better methods of working, and as the country got to be more settled, their task-work became easier of performance and their own land more productive to them; and that tendency to the definition and differentiation of rights, moreover, was at work for their benefit, and the custom of the manor defined what their services were, and they began to acquire rights. From that time they ceased to be pure serfs, and began to tend towards becoming tenants, at first paying purely ...

... principles apply to the lowest and to the highest animals. To all belong certain properties or qualities. As structure is differentiated, or as one animal differs from another owing to greater or less complexity of form, there is a corresponding differentiation of function, none, however, ever losing the fundamental properties of protoplasm. Each organ comes to perform some one function better than all others. This is specialization, and implies advance among animals as ...

... individuals thus resemble one another. Nay, this approximation goes so far as to make even the two sexes much less distinct than they are with us. Professor Pritsch, in his classical treatise on the natives of South Africa (407), dwells especially on the imperfect sexual differentiation of the Bushmen. The faces, stature, limbs, and even the chest and hips of the women differ so little from those of the men that in looking at photographs (as he says and illustrates by specimens), one finds it difficult to tell them apart, though the figures are almost nude. Both ...

Embryology proves that every higher form of individual life becomes what it is by a process of gradual differentiation from an extremely low form; palaeontology proves, in some cases, and renders probable in all, that the oldest types of a group are the lowest; and that they have been followed by a gradual succession of more and more differentiated ...

... peoples are those retained from Dutch practices of a hundred and more years ago, when the Cape of Good Hope still belonged to that nation. Servitude, if not absolute slavery, was then generally recognised as the proper status for coloured aborigines, and that principle of differentiation continues to be upheld and applied in a modified form, it must be admitted, in all the Colonial possessions of Holland. The authority for this stand is sought from ancient biblical history, where the descendants of ...

... a problem to which it is very difficult even to guess at an answer. Does this lack of differentiation in the physiognomy of the Indians point to something much deeper? Are the men really like the women? Such a conception opens up considerations of very great significance. So far as I understand the matter, it appears that, as well as the deep inherent differences between ...

But of this differentiation there is no surety—indeed there are evidences of much duplication of effort in certain districts. In general, however, these statistics do exhibit the great lack of employment in a one-industry district ...

We shall see at once that this is a time both of rapid progress and of great differentiation.

Meantime, astronomy and what the workers of the elder day called natural ...

... natural philosophers maintained confusion devoid of all distinction; except Anaxagoras, who taught that the intellect alone was distinct and without admixture. But previous to the work of distinction Holy Scripture enumerates several kinds of differentiation, the first being that of the heaven from the earth, in which even a material distinction is expressed, as will be shown later (A. 3; Q. 68, A. 1). This is signified by the words, "In the beginning God created heaven and earth." The second distinction ...

In the former, our laws insist upon effective competition; ...
