"Geometry is that of mathematical science which is devoted to consideration of form and size, and may be said to be the best and surest guide to study of all sciences in which ideas of dimension or space are involved. Almost all the knowledge required by navigators, architects, surveyors, engineers, and opticians, in their respective occupations, is deduced from geometry and branches of mathematics. All works of art constructed according to the rules which geometry involves; and we find the same laws observed in the works of nature. The study of mathematics, generally, is also of great importance in cultivating habits of exact reasoning; and in this respect it forms a useful auxiliary to logic."
"A sensible parallax of about one second has been ascertained in the case of the double star [ Alpha Centauri ] of the constellation of the Centaur, and one of the third of that amount for the double star, 61 Cygni; which gave reason to presume that the distance of the former might be about twenty thousand millions of miles, and the latter of much greater amount. If we suppose that similar intervals exist between all the stars, we shall readily see that the space occupied by even the comparatively small number visible to the naked eye, must be vast beyond all powers of conception."
"The evidence of the existence of other astral systems besides our own is much more decided than might be expected when we consider that the nearest of them must needs be placed at a mighty interval beyond our own."
"The elder Herschel, directing his wonderful tube towards the sides of our system, where stars are planted most rarely... was enabled with awe struck mind to see suspended in the vast empyrean astral systems, or, as he called them, firmaments, resembling our own. Like light cloudlets to a certain power of the telescope, they resolved themselves, under a greater power, into stars, though these generally seemed no larger than the finest particles of diamond dust. The general forms of these systems are various; but one at least has been detected as bearing a striking resemblance to the supposed form of our own. The distances are also various... The farthest observed by the astronomer were estimated by him as thirty-five thousand times more remote than Sirius, supposing its distance to be about twenty thousand millions of miles. It would thus appear, that not only does gravitation keep our earth in its place in the solar system, and the solar system in its place in our astral system, but it also may be presumed to have the mightier duty of preserving a local arrangement between that astral system and an immensity of others, through which the imagination is left to wander on and on without limit or stay, save that which is given by its inability to grasp the unbounded."
"My sincere desire in the composition of the book was to give the true view of the history of nature, with as little disturbance as possible to existing beliefs, whether philosophical or religious."
"The great men of antiquity—Cato, Brutus, Cassius, Antony, and Otho—forgot that they had obligations to their race as well as to themselves, when, in the selfish spirit of a pagan philosophy, they considered themselves entitled to put an end to their existence, and remove themselves from the world."
"Now as there are, according to Humboldt, one hundred and seventy words in common between the languages of the new and old continents, and many of these are expressive of the most primitive ideas, there is, by Dr Young's calculation, overpowering proof of the original connection of the American and other human families."
"The peculiarity of six fingers on the hand and six toes on the feet... is then sometimes seen to descend through several generations. It was Mr. Lawrence's opinion that, a pair, in which both parties were so distinguished, might be the progenitors of a new variety of the race who would be thus marked in all future time. It is not easy to surmise the causes which operate in producing such varieties. Perhaps they are simply types in nature, possible to be realized under certain appropriate conditions, but which conditions are such as altogether to elude notice."
"The probability may now be assumed that the human race sprung from one stock which was at first in a state of simplicity if not barbarism."
"It appears from this inquiry that color and other physiological characters are of a more superficial and accidental nature than was at one time supposed."
"Under the flowing robes of nature, where all looks arbitrary and accidental, there is an artificiality of the most rigid kind. The natural, we now perceive, sinks into and merges in a Higher Artificial. ...we conclude, when we attain a knowledge of the artificiality which is at the basis of nature, that nature is wholly the production of a Being resembling, but infinitely greater than ourselves."
"There are nations, such as the inhabitants of Hindostan, known to be one in descent which nevertheless, contain groups of people of almost all shades of color, and likewise discrepant in other of those important features on which much stress has been laid."
"Phenomena appear, in a word, to be explicable on the ground of development. We have already seen that various leading animal forms represent stages in the embryotic progress of the highest—the human being. Our brain goes through the various stages of a fish's, a reptile's, and a mammifer's brain, and finally becomes human."
"The whole history of lamentation, and mourning, and woe, from the beginning of the world—the funeral ceremonies in which the living symbolize the intensity of their grief—the monuments they rear to tell the world for centuries to come of the calamity they have suffered from the stroke of death—are enduring attestations that it is not so much in the removal of one sentient and living being off the earth, as in the change—the calamitous change to the survivors—that death is truly the King of Terrors."
"It must be borne in mind that the gestation of a single organism is the work of but a few days, weeks, or months, but the gestation (so to speak) of a whole creation is a matter probably involving enormous spaces of time."
"I suggest, then... that the first step was an advance under favor of peculiar conditions, from the simplest forms of being, to the next more complicated, and this through the medium of the ordinary process of generation."
"The historical era is, we know, only a small portion of the entire age of our globe. We do not know what may have happened during the ages which preceded its commencement, as we do not know what may happen in ages yet in the distant future. All, therefore, that we can properly infer from the apparently invariable production of like by like is, that such is the ordinary procedure of nature in the time immediately passing before our eyes."
"I contemplate the whole phenomena as having been in the first place arranged in the counsels of Divine Wisdom, to take place, not only upon this sphere, but upon all the others in space, under necessary modifications, and as being carried on, from first to last, here and elsewhere, under immediate favor of the creative will or energy."
"The whole train of animated beings, from the simplest and oldest up to the highest and most recent, are, then, to be regarded as a series of advances of the principle of development, which have depended upon external physical circumstances, to which the resulting animals are appropriate."
"We are drawn on to the supposition, that the first step in the creation of life upon this planet was a chemico-electric operation, by which simple germinal vesicles were produced."
"It may be asked, if He, as appears, has chosen to employ inferior organisms as a generative medium for the production of higher ones, even including ourselves, what right have we, his humble creatures, to find fault? There is, also, in this prejudice, an element of unkindliness towards the lower animals, which is utterly out of place. These creatures are all of them part products of the Almighty Conception, as well as ourselves. ...Let us regard them in a proper spirit, as parts of the grand plan, instead of contemplating them in the light of frivolous prejudices, and we shall be altogether at a loss to see how there should be any degradation in the idea of our race having been genealogically connected with them."
"The nobler orders of being, including man himself, were contemplated from the first, and came into existence by virtue of a law, the operation of which had commenced ages before their forms were realized."
"Is our race but the initial of the grand crowning type? Are there yet to be species superior to us in organization, purer in feeling, more powerful in device and act, and who shall take a rule over us! There is in this nothing improbable on other grounds. The present race, rude and impulsive as it is, is perhaps the best adapted to the present state of things in the world; but the external world goes through slow and gradual changes, which may leave it in time a much serener field of existence. There may then be occasion for a nobler type of humanity, which shall complete the zoological circle on this planet, and realize some of the dreams of the purest spirits of the present race."
"Of late years... it has been successfully shewn that the human race might have had one origin, for anything that can be inferred from external peculiarities."
"The style of living is ascertained to have a powerful effect in modifying the human figure in the course of generations, and this even in its osseous structure."
"While there is such a persistency to ordinary observation, it would also appear that nature has a power of producing new varieties, though this is only done rarely. Such novelties of type abound in the vegetable world, are seen more rarely in the animal circle, and perhaps are least frequent of occurrence in our own race."
"We are ignorant of the laws of variety-production; but we see it going on as a principle in nature, and it is obviously favorable to the supposition that all the great families of men are of one stock."
"I may here refer to a curious mathematical calculation by Dr. Thomas Young, to the effect, that if three words coincide in two different languages, it is ten to one they must be derived in both cases from some parent language, or introduced in some other manner."
"Pause and reflect; take time into consideration: the past history of mankind may be, to what is to come, but as a day."
"Now, as the inferior animals were all in being before man, there was language upon earth long ere the history of our race commenced. The only additional fact in the history of language, which was produced by our creation, was the rise of a new mode of expression—namely that by sound-signs produced by the vocal organs. In other words, speech was the only novelty in this respect attending the creation of the human race."
"Let us look at the inventive class of minds which stand out amongst their fellows—the men who, with little prompting or none, conceive new ideas in science, arts, morals—and we can be at no loss to understand how and whence have arisen the elements of that civilization which history traces from country to country throughout the course of centuries. See a Pascal, reproducing the Alexandrian's problems at fifteen; a Ferguson, making clocks from the suggestions of his own brain, while tending cattle on a Morayshire heath; a boy Lawrence, in an inn on the Bath road, producing, without a master, drawings which the educated could not but admire; or look at Solon and Confucius, devising sage laws, and breathing the accents of all but divine wisdom for their barbarous fellow-countrymen, three thousand years ago—and the whole mystery is solved at once. ...Nations, improved by these means, become in turn foci for the diffusion of light over the adjacent regions of barbarism—their very passions helping to this end, for nothing can be more clear than that ambitious aggression has led to the civilization of many countries. Such is the process which seems to form the destined means for bringing mankind from the darkness of barbarism to the day of knowledge and mechanical and social improvement."
"The book, as far as I am aware, is the first attempt to connect the natural sciences into a history of creation."
"Let the reconciliation of whatever is true in my views with whatever is true in other systems come about in the fulness of calm and careful inquiry."
"I cannot but here remind the reader of what Dr. Wiseman has shewn so strikingly in his lectures, how different new philosophic doctrines are apt to appear after we have become somewhat familiar with them."
"May not the sacred text, on a liberal interpretation, or with the benefit of new light reflected from nature, or derived from learning, be shewn to be as much in harmony with the novelties of this volume as it has been with geology and natural philosophy? What is there in the laws of organic creation more startling to the candid theologian than in the Copernican system or the natural formation of strata?"
"Is it not a wiser course, since reconciliation has come in so many instances, still to hope for it, still to go on with our new truths, trusting that they also will in time be found harmonious with all others? Thus we avoid the damage which the very appearance of an opposition to natural truth is calculated to inflict on any system presumed to require such support."
"Mr. Babbage's illustration powerfully suggests that this ordinary procedure may be subordinate to a higher law which only permits it for a time, and in proper season interrupts and changes it."
"The same law of development presides over the vegetable kingdom. ...where a special function is required for particular circumstances, nature has provided for it, not by a new organ, but by a modification of a common one, which she has effected in development."
"The working-classes require leaders and wise heads from their own body—patriarchs, in the old acceptation of the term—to keep them right in moments of excitement. The causes of early death prevent the existence of such a class of men, sobered and wise from experience, in sufficient numbers to discipline the youthful and fiery spirits who, confident in their ignorance, plunge themselves and those depending on their exertions into ruin."
"It has been among the visions of some dreaming philosophers that human life is capable of almost indefinite extension. The great Condorcet was one of these. He thought that by the removal of the two causes of evil—poverty and superfluity—by destroying prejudices and superstitions, and by various other operations, which he considered the purification of mankind, but which other people would call their pollution, the approach of death would by degrees be farther and farther indefinitely protracted. It is desirable that the practical views entertained by sanitary reformers should be kept widely distinct from any such theories, the character of which has been well drawn by Malthus when he says—"...Though I may not be able in the present instance to mark the limit at which further improvement will stop I can very easily mention a point at which it will not arrive.""
"The progress of knowledge is very irregular, somewhat resembling the movements of an army, of which some battalions are in vigorous health, while others are sickly or overburdened with baggage. The experimental marches on at a good pace; the observational proceeds but slowly; the speculative is left far in the rear."
"The scientific skepticism of our age professes to spring from a sense of the extreme fallaciousness of the human senses, and the liability besetting us all to deceive ourselves into a belief which gratifies the faculty of wonder. It is held as a rare and valuable gift to be able to observe a fact correctly. We are pathetically told that what a man thinks he saw, is often a mere hypothesis of his imagination as to what he saw, and may be wholly wrong."
"Just suppose for a moment that every fact reported to us by others were viewed in the light of the skeptical system, as to the fallaciousness of the senses and the tendency to self-deception. Should we not from that moment be at a stand-still in all the principal movements of our lives?"
"The skeptical view appears to me out of harmony with the inductive philosophy. Bacon gives us many warnings against preconceived opinions and prejudices; but he does not bid us despair of ascertaining facts from our own senses and from testimony. ...we do not find in Bacon any dogma like that of Mr. Faraday that the 'laws of nature are the foundation of our knowledge in natural things,' and that these form our only safe test for any new fact presented to our observation. Bacon's method is rather the contrary, namely, that facts are to serve as the foundation of the laws of nature."
"The limbs of all the vertebrate animals are, in like manner, on one plan, however various they may appear."
"These facts clearly shew how all the various organic forms of our world are bound up in one—how a fundamental unity pervades and embraces them all, collecting them, from the humblest lichen up to the highest mammifer, in one system, the whole creation of which must have depended upon one law or decree of the Almighty, though it did not all come forth at one time. After what we have seen, the idea of a separate exertion for each must appear totally inadmissible."
"This statistical regularity in moral affairs fully establishes their being under the presidency of law. Man is now seen to be an enigma only as an individual; in the mass he is a mathematical problem. It is hardly necessary to say, much less to argue, that mental action, being proved to be under law, passes at once into the category of natural things. Its old metaphysical character vanishes in a moment, and the distinction usually taken between physical and moral is annulled, as only an error in terms. This view agrees with what all observation teaches, that mental phenomena flow directly from the brain."
"To a reasonable mind the Divine attributes must appear, not diminished or reduced in any way, by supposing a creation by law, but infinitely exalted. It is the narrowest of all views of the Deity, and characteristic of a humble class of intellects, to suppose him acting constantly in particular ways for particular occasions. It, for one thing, greatly detracts from his foresight, the most undeniable of all the attributes of Omnipotence. It lowers him towards the level of our own humble intellects. Much more worthy of him it surely is, to suppose that all things have been commissioned by him from the first, though neither is he absent from a particle of the current of natural affairs in one sense seeing that the whole system is continually supported by his providence."
"While the external forms of all these various animals are so different, it is very remarkable that the whole are, after all, variations of a fundamental plan, which can be traced as a basis throughout the whole, the variations being merely modifications of that plan to suit the particular conditions in which each particular animal has been designed to live. Starting from the primeval germ, which, as we have seen, is the representative of a particular order of full-grown animals, we find all others to be merely advances from that type, with the extension of endowments and modification of forms which are required in each particular case; each form, also, retaining a strong affinity to that which precedes it, and tending to impress its own features on that which succeeds."
"What mystery is there here—and how shall I proceed to enunciate the conception which I have ventured to form of what may prove to be its proper solution! It is an idea by no means calculated to impress by its greatness, or to puzzle by its profoundness. It is an idea more marked by simplicity than perhaps any other of those which have explained the great secrets of nature. But in this lies, perhaps, one of its strongest claims to the faith of mankind."
