“ The great source of the success of applying science to trade, and of the beneficent effect of science upon human welfare in general, is simply the influence of demonstrable truth. We know that if we have once discovered all the principles, laws, and conditions of some scientific phenomenon, or of some improved process or result in a manufacture, the reproduction of exactly the same conditions will hereafter enable us to invariably produce the same result. In this respect science differs from dogma, the truth or falsity of which cannot be demonstrated ”

“ The forms in which different truths appear are so various, and those also in which even the same truth may shew itself are so diverse, that it is often impossible to discriminate new truth from old ideas clothed in a new form of words. The newness of an idea is entirely a question of evidence, and to determine it, usually requires a complete knowledge of all the circumstances affecting the particular case. ”

“ A multitude of facts of this kind, and many others, leads us to the conclusion that each new idea requires a cause to produce it, and that human knowledge is subject to the great law of causation; also that the creation of an idea out of nothing would be a miracle, a phenomenon without a cause. Our present knowledge was not created by us, but was originated by previous knowledge and experience, including of course inherited impressions. ”

“ It is chiefly by means of knowledge of these axioms and of the above principles of science, and of their varied and numerous modes of operation and application, that the man of science "explains" the multitudinous phenomena of nature, predicts future events, and is enabled to discover new truths and develope new inventions in the arts. Unlike other persons; when he sees a new effect, or hears of a new phenomenon, he at once refers it to these principles, in order to test its correctness or to explain it.
With regard to the detection of truth, that is often a difficult and complex process. ”

“ All truth whatever is one in character by possessing the inseparable attribute of complete consistency. The truthfulness of scientific knowledge is proved by its agreement with universal experience and with the fundamental logical axioms:—a thing either is or is not:—a thing cannot both be and not be:—a thing must either be or not be:—things equal to the same are equal to each other ”

“ All bodies, whether living or dead, and all forms of energy, appear to be absolutely subject to the great laws of Causation, Progress, Conservation, &c., no one can escape them; the man who transgresses the Law of Progress by being too much in advance of his epoch, is punished as certainly as he who lags behind it ”

“ Truth may be conveniently defined as universal consistency; or that which perfectly conforms to facts, and agrees with the widest experience, when tested by means of all our intellectual powers, the reasoning faculty in particular. The usual modern criterion of it, is consistency with the fundamental axioms of logic, and with all the great principles of nature as established by means of scientific research, such as the universality of causation, the continuity of phenomena, the indestructibility of matter and energy, the convertibility and equivalency of forces, &c. ”

“ Whilst most persons can understand and appreciate the gift of a work of art to a public art collection, few can understand or properly value the discovery and gift of a new scientific truth of far greater intrinsic value to the public stock of knowledge; the treatment received by Priestley and other discoverers in comparison with that of local donors, sufficiently illustrates this. Even publishers of lucrative newspapers prefer to give prizes and pay liberally for sensational tales, than to pay for articles on the public advantages of new scientific knowledge. ”

“ In ordinary writings it is a rare circumstance to meet with an important and really new idea; it is usually in books written by men who are acquainted or imbued with the great principles and truths of science, that the newest demonstrable ideas are most frequently found. The difference between evolving new ideas, and re-expressing and permutating old ones; largely characterises the dissimilarity of the scientific and the literary and theological minds. All however are necessary to the welfare of mankind, the former to advance and the other to maintain the condition of man. ”

“ New truth appears to be usually derived from new physical or mental experiences of phenomena external to our perceiving faculty; either by observing matter or its forces under new conditions or from a new aspect; and the knowledge comes to us either through the avenues of our feelings and senses, or by means of direct observations, by comparison of such impressions, or by inferences drawn from them. ”

“ Immediately a new truth, especially an important one, is discovered, its influence begins to permeate the existing mass of knowledge in various directions, causing us to view many of our old ideas in a new aspect; giving rise also by comparison and inference, and by processes of combination, permutation and analysis of ideas, to a multitude of other new truths, usually less important ones, which themselves also affect previous knowledge in similar ways, and by analogous treatment give rise to additional new conceptions. ”

“ Even in what is termed the "noblest effort of the mind," an act of reasoning or inference, we do not create an idea, but only render explicit in a new form of words, ideas already implicitly contained in the words of the propositions employed, as may easily be rendered manifest by mechanical means in Jevons's "Logical Machine;" a proper inference never contains more than its data. In the so-called "creation" of ideas by the imagination also, the new ideas are evolved from old ones, and rendered explicit by mental processes of analysis, combination, permutation, &c. ”

“ Although originality even in literature and art is very imperfectly encouraged in this country, both art and literature are much more readily understood and appreciated than scientific research, and treated as if they were more important. ”

“ Not only the mental, but also the physical advance of mankind is essentially dependent upon the discovery of new truths. Men's physical actions are determined not alone by their inherited and acquired tendencies and the influence of external nature upon them, but also by their ideas; as a man thinks, so also to a large extent does he act. Nations who do not adopt new ideas do not either mentally or physically advance, but change only so far as their immediate surroundings change ”

“ The number however is large in proportion to the degree of essential importance of the ideas, and is greatest when we employ those of the fundamental principles of nature, already referred to; for instance a greater number of new ideas have been evolved by means of appropriate mental processes from the law of gravitation and from that of electro-magnetism than from any minor truth in science. ”

“ Our scientific inventions also, being mental conceptions, an unlimited number of them cannot be made by means of a limited stock of old knowledge. It was in consequence of this limit, viz., the impossibility of actually creating ideas out of nothing, that human knowledge was not more advanced by metaphysical speculations until science with its experiments and observations came to its assistance. These various facts prove the statement made in the Preface of this book, that present knowledge only enables mankind to maintain its present state. ”

“ Frequently also the truthfulness or otherwise of a statement cannot be decided in any degree in consequence of the absence of suitable or sufficient evidence, and for that we may have to wait for ages. We are now waiting for evidence necessary to decide many questions respecting the human mind. ”

“ Persons therefore who are the least familiar with great demonstrable principles are usually the least able to conceive new truthful ideas of intrinsic importance, or to draw new verifiable inferences of much theoretical value. ”

“ If we say that a piece of clean iron, immersed in a solution of blue vitriol, will become covered with a layer of metallic copper, and we find upon trial that this result invariably occurs when we fulfil those conditions, we may be certain that our knowledge of this phenomenon and its conditions is also of a definite and certain character. ”

“ It is evident from this, that much of the mental activity around us is not progress, but rather a process of maintaining present state, a prevention of decline, a continually going round and round in conventional varied step, a kind of intellectual mill. ”

“ Of all subjects, the simple sciences of physics and chemistry, are at the present time, apparently making the most rapid advance, and the chief reasons for this probably are, 1st. they treat of facts and principles which can be verified, and 2nd. because the more complex sciences, together with the arts and manufactures based upon them, can only improve in proportion as they are developed. ”

“ But although we evolve truthful new conceptions from previous ones by these purely mental methods, there is a limit to the number capable of being evolved from a limited stock of ideas, because the number of combinations and permutations of such a stock, though usually large, are themselves limited. ”

“ Similarly, when we become able to predict with certainty the conditions of the Sun's surface, we shall probably also be able to predict severe winters, famines, &c., and therefore be prepared to suggest precautions to be taken against them. ”

“ The Principle of Gravitation, demonstrated by Newton, explains a vast number of facts relating to the motions of the Heavenly bodies:—the Undulatory Theory of Light, largely developed by the labours of Fresnel, renders equally clear and systematic an almost endless number and variety of optical phenomena ”

“ And the great mental value of these comprehensive ideas to mankind, consists largely in relieving the memory and diminishing mental confusion, by co-ordinating a large number of different facts and apparently inconsistent phenomena by means of a general conception which embraces the whole of them. ”

“ It falls to the lot of but comparatively few men to discover or evolve important new truths. The great majority of learned men also, have through all historic time been occupied, and are still, not in evolving new ideas, but in re-expressing old ones in different forms of words ”
