"Demonstrable" Quotes from Famous Books
... to think what they would have said. I certainly should not like to have been the officer of Nelson who suddenly discovered his French blood on the eve of Trafalgar. I should not like to have been the Norfolk or Suffolk gentleman who had to expound to Admiral Blake by what demonstrable ties of genealogy he was irrevocably bound to the Dutch. The truth of the whole matter is very simple. Nationality exists, and has nothing in the world to do with race. Nationality is a thing like a church or a secret society; it is a product of the ... — Heretics • Gilbert K. Chesterton
... remind you that the unattainableness is by no means so demonstrable as some people seem to think. A very tiny circle may have the same centre as one that reaches beyond the suburbs of the universe, and holds all stars and systems within its great round. And the tiniest circle will have the same geometrical laws applied to it as the greatest. The difference between ... — Expositions of Holy Scripture - Ephesians; Epistles of St. Peter and St. John • Alexander Maclaren
... man can go farther to illustrate than that of another. The force of high authority is greater in the three former sciences than in the latter. Theism and Atheism I hold to be neither of them strictly demonstrable. You, Dr. Priestley, agree with me in that. Still I hold the question capable of being illustrated by argument, and I should hold the authority of great men's names to be of more weight in this subject, were I not necessarily forced to consider that all education ... — Answer to Dr. Priestley's Letters to a Philosophical Unbeliever • Matthew Turner
... is demonstrable that if there be three Persons and one God, each Person must be God, and yet there cannot be three distinct Gods, but one. For if each Person be not God, all three cannot be God, unless the Godhead have Persons in ... — Coleridge's Literary Remains, Volume 4. • Samuel Taylor Coleridge
... interior as about his worldly importance and plight. There then seems to be more reality about somatic than about personal delusions: the contents of somatic delusions are rather more apt to correspond with demonstrable realities than the contents of personal delusions. Accordingly our analysis of delusional contents includes a hint also as to genesis. Taken naively, the facts suggest a somatic genesis for somatic delusions exactly in proportion as these delusions ... — The Journal of Abnormal Psychology - Volume 10
... as I have called it, the Vedic Theistic Association, also professedly theistic. Polytheism and pantheism alike, the [A]ryas repudiate. For the gods and goddesses of the Hindu pantheon, the founder of the [A]ryas declared there was no recognition in the Vedas. Demonstrable or not, that is the [A]rya position. The rejection of pantheism by such a body is noteworthy, for pantheism is identified with India and the Vedanta, the most widely accepted of the six systems of Indian ... — New Ideas in India During the Nineteenth Century - A Study of Social, Political, and Religious Developments • John Morrison
... to give my opinion of this propriety of length, I should say it consisted in the depth and declivity of the shoulders, and in the length of the quarters and thighs, and the insertion of the muscles thereof. The effect of the different position or attitude of the shoulders in all Horses, is very demonstrable: if we consider the motion of a shoulder, we shall find it limited to a certain degree by the ligamentous and the tendinous parts, which confine it to its proper sphere of acting; so that if the shoulder stand upright, the Horse will not be able to put his toes far before him, but ... — A Dissertation on Horses • William Osmer
... the external world is a repository of objects conceived by superposing perceptions that exist together. Being formed on different principles these two orders of conception—the logical and the physical—do not coincide, and the attempt to fuse them into one system of demonstrable reality or moral physics is doomed to failure by the very nature of the terms compared. When the Eleatics proved the impossibility—i.e., the inexpressibility—of motion, or when Kant and his followers proved the unreal character of ... — The Life of Reason • George Santayana
... are growing more and more handsome every year for just this reason. They are growing rounder of chest, fuller of limb, gaining, substance and development in every direction. Whatever may be urged to the contrary we believe this to be a demonstrable fact. When the rising generation of American girls once begin to wear thick shoes, to take much exercise in the open air, to skate, to play at croquet, and to affect the saddle, it not only begins to grow more wise but more ... — Advice to a Mother on the Management of her Children • Pye Henry Chavasse
... solution in the acid during parting is small, but easily demonstrable. On a 500-milligram charge of bullion it may amount to from .05 to .15 milligram; i.e. from .01 to .03 per cent. It is due to gold actually dissolved and not ... — A Textbook of Assaying: For the Use of Those Connected with Mines. • Cornelius Beringer and John Jacob Beringer
... the whole conduct of the late fight was ill.... He says three things must be remedied, or else we shall be undone by their fleet. 1. That we must fight in line, whereas we fight promiscuously, to our utter demonstrable ruin: the Dutch fighting otherwise, and we whenever we beat them. 2. We must not desert ships of our own in distress, as we did, for that makes a captain desperate, and he will fling away his ship when there are no hopes left him ... — Fighting Instructions, 1530-1816 - Publications Of The Navy Records Society Vol. XXIX. • Julian S. Corbett
... This demonstrable position was accepted without hesitation as ground for a toast; but Mr. Bates, apparently thinking that his song was not an equally reasonable sequence, ignored the second part of Mr. Bellamy's proposal. So Mrs. Sharp, who had been heard to say that she had no ... — Scenes of Clerical Life • George Eliot
... necessary, plans for which are now under consideration. At present, so large is the demand upon its facilities that "blocks" and serious delays are of daily occurrence. That there will be ample and remunerative business for two canals is easily demonstrable by the statistics of the original company, which show a most remarkable annual increase. It is a singular fact worthy of mention, that, with all our modern improvements and progressive ideas, the Egyptians ... — Due West - or Round the World in Ten Months • Maturin Murray Ballou
... could possibly be desired. They were inquiring too, not into any speculative or occult theory, upon which there might be a chance of their being led away by sophistical representations, but they were inquiring into the existence of facts only — plain demonstrable facts, which were in their own nature palpable to every observer." ["Introduction to the Study of Animal Magnetism," p. 27.] M. Dupotet might not unreasonably be asked whether the very same arguments ought not to be applied to the unfavourable report drawn up by the able M. Dubois ... — Memoirs of Extraordinary Popular Delusions - Vol. I • Charles Mackay
... exist have an uncared-for look, neither are the village folks so well dressed as in regions of peasant property. In fact, I should say, after a very wide experience, that peasant property invariably uplifts and non-propertied labour drags down. This seems to me a conclusion mathematically demonstrable. ... — In the Heart of the Vosges - And Other Sketches by a "Devious Traveller" • Matilda Betham-Edwards
... suspension, and continuation of these movements, in all their forms are due to purely vito-magnetic force, we think demonstrable. Thus, no other can act so instantaneously, none with such varied exhibitions of power, and none so ... — New and Original Theories of the Great Physical Forces • Henry Raymond Rogers
... times, and constitute the genealogy of the piano-forte, we have the dulcimer and psaltery, and all the Egyptian, Grecian, and Roman harps and lyres which were struck with a quill or plectrum. No product of human ingenuity has been the outcome of a steady and systematic growth from age to age by more demonstrable stages than this most remarkable of musical instruments. As it is not the intention to offer an essay on the piano, but only to make clearer the conditions under which a great school of players began to appear, the antiquities ... — Great Violinists And Pianists • George T. Ferris
... assimilation of ambitious, factious and disappointed members, to the little, but solid, and unbiassed party, the more frequent ill effects, and consequences of so unequal a mixture, so long continued, are demonstrable and apparent. For while scarce any man comes thither with respect to the publick service, but in design to make and raise his fortune, it is not to be expressed, the debauchery, and lewdness, which, upon occasion of election to Parliaments, are now grown habitual thorow the nation. ... — Andrew Marvell • Augustine Birrell
... constant appeal is made to intuitive knowledge. It is said to be impossible to give expression to certain truths; that they are not demonstrable by syllogisms; that they must be learnt intuitively. The politician finds fault with the abstract reasoner, who is without a lively knowledge of actual conditions; the pedagogue insists upon the necessity of developing the intuitive faculty in the pupil before everything else; the critic in ... — Aesthetic as Science of Expression and General Linguistic • Benedetto Croce
... subjects cannot be answered categorically, but I hope to be able, by setting down my own observations and using trustworthy reports, to give others the material on which to exercise their judgment. In the first place, I think it demonstrable that a person would profitably exchange 160 acres of farming land east of the one hundredth parallel for ten acres, with a water right, ... — Our Italy • Charles Dudley Warner
... as it is today. This he made one of the fundamental rules of his life. He was helped in this, he told me in substance, by an early faith which with the passing of the years has ripened with him into a demonstrable conviction—that there is a Spirit of Infinite Life back of all, working in love in and through the lives of all, and that in the degree that we realise it as the one Supreme Source of our lives, and when through desire and will, which is ... — The Higher Powers of Mind and Spirit • Ralph Waldo Trine
... and human character who have studied Friedrich sufficiently, "is greater than ever," in these four Years now coming. [Berenhorst, in Kriegskunst; Retzow; &c.] And this, I have found more and more to be a true thing; verifiable and demonstrable in time and place,—though, unluckily for us, hardly in this time or this place at all! A thing which cannot, by any method, be made manifest to the general reader; who delights in shining summary feats, and is impatient of tedious ... — History of Friedrich II. of Prussia, Vol. XIX. (of XXI.) • Thomas Carlyle
... prythee do so. Something sure of State, Either from Venice, or some vnhatch'd practise Made demonstrable heere in Cyprus, to him, Hath pudled his cleare Spirit: and in such cases, Mens Natures wrangle with inferiour things, Though great ones are their obiect. 'Tis euen so. For let our finger ake, and it endues Our other healthfull ... — The First Folio [35 Plays] • William Shakespeare
... meane therby. A Mechanicien, or a Mechanicall workman is he, whose skill is, without knowledge of Mathematicall demonstration, perfectly to worke and finishe any sensible worke, by the Mathematicien principall or deriuatiue, demonstrated or demonstrable. Full well I know, that he which inuenteth, or maketh these demonstrations, is generally called A speculatiue Mechanicien: which differreth nothyng from a Mechanicall Mathematicien. So, in respect of diuerse actions, one man may haue the name of sundry ... — The Mathematicall Praeface to Elements of Geometrie of Euclid of Megara • John Dee
... territory of Kasi and Videha, but the Brahmanic landscape lies mainly to the west and the Buddhist mainly to the east of this region. In the Buddhist sphere it is clear that in the youth of Gotama Brahmanic doctrines and ritual were well known but not predominant. It is hardly demonstrable from literature, but still probable, that the ideas and usages which found expression in Jainism and Buddhism existed in the western districts, though less powerful ... — Hinduism and Buddhism, Vol I. (of 3) - An Historical Sketch • Charles Eliot
... sentiment of nationality dwell in unison with the ideal of peace? Is the love of liberty compatible with the full realization of the common will? If reconcilable in theory, may not these ideals collide in practice? Are there not clearly occasions demonstrable in history when development in one direction involves retrogression in another? If so, how are we to strike the balance of gain and loss? Does political progress offer us nothing but a choice of evils, or may we have some confidence that, in solving the most pressing problem ... — Liberalism • L. T. Hobhouse
... overwhelmed with the charge of blood forced in upon them, that the flesh is lacerated and the vessels ruptured. Nothing of the kind as an effect of heat, or pain, or the vacuum force, is either credible or demonstrable. ... — The Harvard Classics Volume 38 - Scientific Papers (Physiology, Medicine, Surgery, Geology) • Various
... what Mrs. Minturn founded some of her arguments upon," he said, as the striking of the clock warned him of his dinner hour. "Well, I wonder, were those cases 'miracles'— just supernatural wonders, performed merely to prove Jesus' authority to preach a new gospel? or were they 'governed by a demonstrable Principle,' as she affirms, brought to earth for suffering humanity to learn and practice, and so be redeemed ... — Katherine's Sheaves • Mrs. Georgie Sheldon
... immaterial. Brothers and sisters are only the children of one mother. A man does not bequeath his property to his children, but to the children of his sister, that is to say, to his nephews and nieces, as his nearest demonstrable blood relatives. A chief of the Way people explained to me in horrible English: "My sister and I are certainly blood relatives, consequently her son is my heir; when I die, he will be the king of my town." "And your father?" I inquired. "I don't know ... — Woman under socialism • August Bebel
... accept the Scriptures upon the authority of unknown men, and upon no other demonstrable ... — God and my Neighbour • Robert Blatchford
... promote your happiness—nor are you less selfish if you give your all to the needy—you are still equally doing that which promotes your happiness. That it is more blessed to give than to receive is a terse statement of a law scientifically demonstrable. You all know how far more exquisite is the pleasure that comes from giving than that which comes from receiving. Is not one who prefers to give then simply selfish with a greater wisdom, a finer skill for the result desired—his own pleasure? The man we call good is not less ... — The Seeker • Harry Leon Wilson
... divided into two groups of men; the first, those whose God is their God, and whose glory is their glory, who mind heavenly things; and the second, men whose God is their belly, and whose glory is in their shame, who mind earthly things. That is just as demonstrable a scientific fact as the separation of land from water. There may be any quantity of intermediate mind, in various conditions of bog; some, wholesome Scotch peat,—some, Pontine marsh,—some, sulphurous slime, like what people call water in English manufacturing towns; but the ... — A Wanderer in Venice • E.V. Lucas
... Matter: Matter is a function of thought: Mind is Noumenon the unseen and unknown, as contrasted with Phenomena the seen and known; the universe, the creation of the mind; the mind, the product of the universe. All these ideas and many others so widely differing can none of them receive a demonstrable proof;—these contrary statements show how far we are from possessing any real knowledge of what mind is. After all that has been written, elaborated and imagined, do we actually know more than ... — Cobwebs of Thought • Arachne
... determined; undetermined through any point without, and determined through itself. Geometry therefore supplies philosophy with the example of a primary intuition, from which every science that lays claim to evidence must take its commencement. The mathematician does not begin with a demonstrable proposition, but with ... — Biographia Literaria • Samuel Taylor Coleridge
... regarded as certain that most of the aberrations discoverable in Codexes of the Sacred Text have arisen in the first instance from the merest inadvertency of the scribes. That such was the case in a vast number of cases is in fact demonstrable. [Inaccuracy in the apprehension of the Divine Word, which in the earliest ages was imperfectly understood, and ignorance of Greek in primitive Latin translators, were prolific sources of error. The influence of Lectionaries, ... — The Causes of the Corruption of the Traditional Text of the Holy Gospels • John Burgon
... of social order is understood, and I felt it my duty in 1847 to present the law of justice in relation to "The Land and the People," with very little hope that the doctrine presented would ever become in my own lifetime a basis of political action, since other ideas equally true and equally demonstrable have to bide their time. But the toilers who suffer from the lack of employment have furnished an eager audience to the land reformers, and the great land question is destined to agitate the nations for a century ... — Buchanan's Journal of Man, February 1887 - Volume 1, Number 1 • Various
... of the Cabinet, Hamilton, in the peace of his library, with Angelica sorting his pages,—until she went to the North,—had written a series of papers defending the proclamation. They were so able and convincing, so demonstrable of the treasonable efforts of the enemy to undermine the influence of the Administration, so cool and so brilliant an exposition of the rights and powers of the Executive, that on July 7th Jefferson wrote to Madison: "For God's sake, my dear sir, take up your pen. Select the ... — The Conqueror • Gertrude Franklin Atherton
... indeed beware how they profanely touch—that of theology. Strange, and miserably strange, that while they are modest enough to doubt their powers, and pause at the threshold of sciences where every step is demonstrable and sure, they will plunge headlong, and without one thought of incompetency, into that science in which the greatest men have trembled, and the wisest erred. Strange, that they will complacently and pridefully bind up whatever ... — Sesame and Lilies • John Ruskin
... the provinces of science and art, we may briefly say, that science is concerned with the discovery of demonstrable principles, and the deduction of undeniable corollaries; while art is occupied with expression, performance, and the creative faculty with which man has been endowed. Music and astronomy are both sciences, that is, founded upon certain fixed and ... — The Continental Monthly, Vol. 5, No. 5, May, 1864 - Devoted To Literature And National Policy • Various
... method of such action as has been described on the part of the invisible and universal Energy, for we cannot even explain the nexus between an act of human volitional energy and the raising of an arm. There are the facts, demonstrable and undeniable, but the how of those facts, no man on this earth knoweth or perhaps ever will know. Well may Browning profess himself content to endure in patience the ignorance which is our lot here, if only ... — Morality as a Religion - An exposition of some first principles • W. R. Washington Sullivan
... suddenly came to me: How good it is to be at peace with God, and to be able and willing to say, My Father! That the whole of the surging and flaming sun was actually down in my straitened and hampered heart at that idle moment over my paper is scientifically demonstrable; for only that which is in the heart of a man can kindle the passions that are in the heart of that man; and nothing is more sure to me than that the great passions of fear and love, wonder and rapture were at that moment at a burning point within me. There is a passage well on in the ... — Bunyan Characters - Third Series - The Holy War • Alexander Whyte
... the earth's stability; but in his preface he sounds a remarkable warning. He mentions the great mistake into which St. Augustine led the Church regarding the doctrine of the antipodes, and says, "If within a few years or in the next generation it should prove as certain and demonstrable that the earth is moved, as it is now that there are antipodes, those that have been zealous against it, and engaged the Scripture in the controversy, would have the same reason to repent of their forwardness that St. Augustine would now, if he were ... — History of the Warfare of Science with Theology in Christendom • Andrew Dickson White
... chapbook and lasted long in that condition. Although we Englishmen provide the fun, he is certainly no Englishman who resents the fact or fails to enjoy the result, not to mention that we "could tell them tales with other endings." It is, for instance, not quite historically demonstrable that in crossing a river many English horsemen would be likely to be drowned, while all the French cavaliers got safe through; nor that, in scouring a country, the Frenchmen would score all the game and all the best beasts and poultry, while ... — A History of the French Novel, Vol. 1 - From the Beginning to 1800 • George Saintsbury
... time. In the central blinds of bone, as they stand in their natural order, there are certain curious marks, curves, hollows, and ridges, whereby some whalemen calculate the creature's age, as the age of an oak by its circular rings. Though the certainty of this criterion is far from demonstrable, yet it has the savor of analogical probability. At any rate, if we yield to it, we must grant a far greater age to the Right Whale than at first glance ... — Moby Dick; or The Whale • Herman Melville
... assert that, at any time between 1776 and 1790, a proposition to surrender the sovereignty of the States and merge them in a central government would have had the least possible chance of adoption? Can any historical fact be more demonstrable than that the States did, both in the Confederation and in the Union, retain their sovereignty and independence as distinct communities, voluntarily consenting to federation, but never becoming the fractional ... — The Rise and Fall of the Confederate Government • Jefferson Davis
... and of all previous times—authors as exclusively and painstakingly trained to the literary trade as was General Grant to the trade of war. This is not a random statement: it is a fact, and easily demonstrable. I have a book at home called Modern English Literature: Its Blemishes and Defects, by Henry H. Breen, a countryman of Mr. Arnold. In it I find examples of bad grammar and slovenly English from the pens of Sydney Smith, Sheridan, Hallam, Whately, Carlyle, Disraeli, ... — Mark Twain, A Biography, 1835-1910, Complete - The Personal And Literary Life Of Samuel Langhorne Clemens • Albert Bigelow Paine
... present century, that Prevost and Dumas in France, and, later on, Doellinger, Pander, Von Baer, Rathke, and Remak in Germany, founded modern embryology; while, at the same time, they proved the utter incompatibility of the hypothesis of evolution, as formulated by Bonnet and Haller, with easily demonstrable facts. ... — Darwiniana • Thomas Henry Huxley
... above-named authorities, being probably ignorant of them all. His reasoning upon the point, does not appear to me to be worthy of a detailed answer.[165] That the possessive case of nouns is not an adjective, is demonstrable; because it may have adjectives of various kinds, relating to it: as, "This old man's daughter."—Shak. It may also govern an other possessive; as, "Peter's wife's mother."—Bible. Here the former possessive is governed by the ... — The Grammar of English Grammars • Goold Brown

... Sirius. To cite one example out of a hundred, every philologist knows that s may become r, and that the broad a-sound may dwindle into the closer o-sound; but when you adduce some plausible etymology based on the assumption that r has changed into s, or o into a, apart from the demonstrable influence of some adjacent letter, the philologist will ... — Myths and Myth-Makers - Old Tales and Superstitions Interpreted by Comparative Mythology • John Fiske
... General Booth's personal force and commanding power was an open one. To him there were no realities so demonstrable as the realities of the spiritual world—most of all, the reality of Christ's real personal presence and saving power to-day. He found that unquestioning faith in Christ's saving power worked everywhere and under all conditions. We differed from ... — The Authoritative Life of General William Booth • George Scott Railton
... counsel and action too, to a perfect civil man; faith and works too, to him that is perfectly spiritual. But because it is easily said, I believe, and because it doth not easily lie in proof, nor is easily demonstrable by any evidence taken from my heart (for who sees that, who searches those rolls?) whether I do believe or no, is it not therefore, O my God, that thou dost so frequently, so earnestly, refer us to the hand, to the observation of actions? There is a ... — Devotions Upon Emergent Occasions - Together with Death's Duel • John Donne
... to the Union, I shall, if President, be willing to give up the ghost, and let Breckinridge take the government." Thus, even excluding the more problematical chances which lay hidden in filibustering enterprises, there was a possibility, easily demonstrable to the sanguine, that a decade or two might change mere numerical preponderance from the free to the slave-States. Nor could this possibility be waved aside by any affectation of incredulity. Not alone Mr. Buchanan but ... — Abraham Lincoln, A History, Volume 2 • John George Nicolay and John Hay

... him. It came to her almost in a logical development; it found her grave, calm, and receptive. She had even a private formula of gratitude that the thing which happened to everybody, and happened to so many people irrelevantly, should arrive with her in such a glorious defensible, demonstrable sequence. Toward him it gave her a kind of glad secret advantage; he was loved and he was unaware. She watched his academic awkwardness in church with the inward tender smile of the eternal habile feminine, and when ... — The Imperialist • (a.k.a. Mrs. Everard Cotes) Sara Jeannette Duncan
... you there, gossip, and will undertake to show the company"—here he looked around upon us and nodded his head in a confident way—"that there is a grain of sense in what the child has said; for look you, it is of a certainty most true and demonstrable that it is a man's head that is master and supreme ruler over his whole body. Is that granted? Will any deny it?" He glanced around again; everybody indicated assent. "Very well, then; that being the case, no part of ... — Personal Recollections of Joan of Arc - Volume 1 (of 2) • Mark Twain
... more. Eighteenth-century economists argued in favor of stimulating population in order to make wages low, and thereby win in international competition. They never had a compunction or a doubt about this argument. No wonder it has been asserted that all truth, except that which is mathematically demonstrable, is only a function of the age. When the earth is underpopulated and there is an economic demand for men, democracy is inevitable. That state of things cannot be permanent. Therefore democracy cannot last. It contains no absolute and "eternal" truth. While it lasts a certain ... — Folkways - A Study of the Sociological Importance of Usages, Manners, Customs, Mores, and Morals • William Graham Sumner
... prisoners whether in close bondage or in society, must confirm them in evil. The effect of transportation is to force the free working classes from the island, and to supply their place with prisoners. It appears, therefore, demonstrable that as far as they are the instruments of demoralization, it is inevitable, from their numerical preponderance. Their condition affords no prospect of extensive reformation, and whatever evils they may be supposed to create, are essential ... — The History of Tasmania, Volume I (of 2) • John West
... at this price, not that I estimate the value of the invention so low, for it is perfectly demonstrable that the sum above mentioned is not half its value, but that I may have my own mind free to be occupied in perfecting the system, and in a general superintendence of it, unembarrassed by the business arrangements necessary to secure ... — Samuel F. B. Morse, His Letters and Journals - In Two Volumes, Volume II • Samuel F. B. Morse
... feels inclined to see quatrains—a form, as we shall see, agreeable to early Spain, and very common in all European nations at this stage of their development. But it is very seldom that either is clearly demonstrable except in parts, while neither maintains itself for long. Generally the pages present the spectacle of an intensely irregular mosaic, or rather conglomerate, of small blocks of assonance or consonance put together on no discoverable system whatever. It is, of course, fair to remember ... — The Flourishing of Romance and the Rise of Allegory - (Periods of European Literature, vol. II) • George Saintsbury
... sub-class should possibly comprise less than the class to be divided'; or else we must confine the test to (a) thoroughly empirical divisions, as in dividing Colour into Red and Not-red, where we know that both sub-classes are real; and (b) divisions under demonstrable conditions—as in dividing the three kinds of triangles by the quality equilateral, we know that it is only applicable to acute-angled triangles, and do not attempt to divide the right-angled or obtuse-angled ... — Logic - Deductive and Inductive • Carveth Read
