"Theoretical" Quotes from Famous Books



... would not be complete if we did not take the religious side of his character into consideration. His religion is not of the theoretical kind, but it is a constant, earnest, sincere practice. It is neither demonstrative nor loud, but manifests itself in a quiet, practical way, and is always at work. It is not aggressive, which sometimes is troublesome, if not impertinent. In him, religion ...

... something else. But is it necessarily absurd to speak of a system of things—not, of course, a system of things in which there is change, succession, an earlier and a later, but still a system of things of some sort—in which there obtain no time relations? The problem is, to be sure, one of theoretical interest merely, for such a system of things is not the world ...

... with the best results. Whenever his kite-thermometers, sent to a fixed height which he determines independently by a specially devised kite-quadrant, show actual readings which are either warmer or cooler than the theoretical readings, he prophesies that the weather will, within a few hours, become warmer or colder at the earth's surface, and these prophecies are fulfilled in a large majority of cases. If the kite-thermometers show exactly the temperature which the law would call for, he ...

... revived and reinforced Sklavenmoral that besets all of us of English speech—the huggermugger morality of timorous, whining, unintelligent and unimaginative men—envy turned into law, cowardice sanctified, stupidity made noble, Puritanism. And in the theoretical field there is an even more luxuriant crop of bosh. Mountebanks almost innumerable tell us what we should believe and practice, in politics, religion, philosophy and the arts. England and the United States, between them, house ...

As by now all his fingers were used up, he uncrooked all his fingers and went on: "This is the theoretical view; but I imagine you have done me the honor to apply to me in order to learn its application in practice.

In 537 it had already been explained to the King of Ts'u that on the occasions of the triennial visits of vassals to the Emperor (probably only theoretical visits at that date) wine was served at long tables in full cups, but was only drunk at the proper ritualistic moment. Two years after that the King of Ts'u was described as being at his wine, and therefore in the proper frame of mind ...

It is made with an egg, that miracle of nature, which the theoretical Burnet has compared to creation. An egg contains water within its beautiful smooth surface; and an unformed mass, by the incubation of the parent, becomes a regular animal, furnished with bones and sinews, and covered with feathers. Let us consider; can there be more ...

... was more than that, however: he, too, was capable of manly ambition; he, too, had taken a breakneck risk. He had perfected and patented at Washington an invention of which he had seen a drawing, by accident, in a scientific journal—Engineering, or another—a purely theoretical invention. The inventor himself, a young London electrician, declared it to be unrealizable. Well, he, Trampy—Poland had helped him with her purse; she was very nice about it—he, Trampy, had had the thing made. He had deposited the models at the Patent Office; and the apparatus itself was ...

It is a pacific system, operating to cordialise mankind, by rendering nations, as well as individuals, useful to each other. As to the mere theoretical reformation, I have never preached it up. The most effectual process is that of improving the condition of man by means of his interest; and it is on this ground that I take my stand. If commerce were permitted to act to the universal extent it is capable, it would extirpate the ...

We speak of a lover possessing the person of his mistress. We speak of offences against ...

... America is the only nation in the world that is founded on a creed. That creed is set forth with dogmatic and even theological lucidity in the Declaration of Independence; perhaps the only piece of practical politics that is also theoretical politics and also great literature. It enunciates that all men are equal in their claim to justice, that governments exist to give them that justice, and that their authority is for that reason just. It certainly does condemn anarchism, and it ...

Very old nautical observations, which I have had occasion to confirm by comparing the longitude given by the chronometer with that which the pilots obtained by their reckoning, are, however, contrary to these theoretical ideas. In both hemispheres, the polar currents, when they are perceived, decline a little to the east; and it would seem that the cause of this phenomenon should be sought in the constancy of the westerly winds which prevail in the high latitudes. ...

But we may point out here that it is not a theory, based merely upon one set of facts, but one singularly rich in confirmation. We can construct, on purely anatomical grounds, a theoretical pedigree.

It is the author's view that the judge should understand these relations not merely in their narrower practical bearings, but in their larger and more theoretical aspects which the study of psychology as a comprehensive science sets forth.

... the average speed. At turns approaching ninety degrees, the curve is likely to be of such short radius that it is impossible to maintain the ordinary road speed around the curve, even with the maximum superelevation permissible. It is good practice to provide the theoretical superelevation on all curves having radii greater than 300 feet for vehicle speeds of the maximum allowed by law, which is generally about 25 miles per hour. Where the radii are less than 300 feet, the theoretical superelevation for the maximum vehicle speeds gives a superelevation too great for ...

... outline of this famous tribute by an unbelieving philosopher to the merits of Christianity as a scheme of moral discipline. Now, it must be remembered that Marcus Aurelius was by profession a Stoic; and that generally, as a theoretical philosopher, but still more as a Stoic philosopher, he might be supposed incapable of descending from these airy altitudes of speculation to the true needs, infirmities, and capacities of human nature. Yet strange it is, that he, of all the good emperors, was the most thoroughly human ...

... was then inevitable; for it is impossible that a new principle can ever be received simply and without alloy into minds, which are at the same time occupying themselves with its utmost practical or even theoretical consequences. In this sense there is great truth in what Comte says about the value of the separation of the spiritual from the temporal authority. The power of directly realizing a new religious principle, just because it draws away attention from the principle itself to ...

The industry may be far below the theoretical standard of the community, and the workers may be too wretched to protest. Conditions may be above the standard, and the workers may protest violently. The standard is at best a vague measure. However, we shall assume ...

About the same time he also received the appointment of Field-Work Instructor and Adjutant at Chatham, where his practical knowledge gained in the Sebastopol trenches was turned to good account in the theoretical training of future officers of his Corps.

The business of a barber is one that is much followed by the Mulattos of Lima. In that occupation they are quite ...

But as he lives socially, he has in practice to outgrow it, and this lands him in a serious theoretical dilemma. He has to learn to live with others who differ from him in their dogmatizing. Social life plainly would become impossible if all rigidly insisted on the absolute rightness of their own beliefs and the ...

One recalls how Beethoven in his lifetime was condemned by the theorists, and how almost apologetically he himself referred at the end to his own deliberate breaking of the rules. But now, it appears, the musical theorists are beginning to realise that theory must ...

The king and minister at least conceived between them a scheme of island ...

According to Sorel, the really essential thing in Marx's ...
