Uniformity of nature

“ The uniformity of nature, in the above sense, although it is assumed in the practice of science, must not, in its generality, be regarded as a kind of major premiss, without which all scientific reasoning would be in error. ”

“ Let us consider now what scientists mean by the uniformity of nature. The uniformity of nature may be interpreted in various ways. It may mean that nature is regulated by universal laws. In this form, it is obviously not a presupposition adopted uncritically. ”

“ Call this an observed uniformity of nature: we hold ourselves justified in expecting that the observed uniformities of nature will continue. Such an observed uniformity—that All animals have a nervous system, that All animals die, that Quinine cures ague—is also called an Empirical Law. ”

“ Surely we ought to expect some pretty substantial evidence for such a violation of "the observed uniformity of nature." We generally boast that we have outgrown the crude ideas of the earlier years of the science when they spoke of "ages" of limestone making or of sandstone making; but it seems that some of us have not yet attained to that broad view of the essential unity of nature in which the flora and fauna of our world are seen to be just as indissolubly connected with each other. ”

“ The uniformity of Nature is an old discovery, and one of them is like another. As this is not a treatise on Natural History but a biography of an individual, I must restrict myself to what was peculiar to our heroine and her companion, and leave others to dilate upon what may be generally seen in her fellow-creatures of the same species. ”

“ Assuming the uniformity of nature, I carry forward and backward both the mental and the material series. A uniformity is observed in each, and a parallelism is observed between them, whenever observations can be made. ”

“ We may, no doubt, make a still wider generalization, and say that every event in Nature is invariably preceded by some definite complex of conditions, {34} and so arrive at a general law of the Uniformity of Nature. ”

“ The uniformity of Nature may be a postulate, but you cannot find any logical basis for it. Or, to come down from heights of that sort, have you ever laid to heart, brother, that the only unchangeable thing in this world is change, and the only thing certain, that there is no continuance of anything ”

“ Whether this uniformity which binds man and nature into one consistent whole is a uniformity of will or a uniformity of necessity, is quite another question. It is a metaphysical and not a scientific inquiry; and the metaphysical answer, whatever it may be, is one for which science does not and need not pause. So long as nature is granted to be uniform, it matters not to science whether the uniformity is of necessity or is freely willed. In either case the sequences or co-existences described by science will continue, under the circumstances described, to happen as described. ”

“ Consequently, when we see man excited to follow any avocation in life, whether it be for gold, silver, or other precious ores, for which he leaves his all, acts unwisely and inconsistently, sacrificing his home, his family, and everything dear and near to him, we can exclaim, "This wild career of man is not the only wildness exhibited in nature."
If you refer back to the earliest ages, and trace the history of the world, where can you find uniformity in nature's works? If you can find a uniformity at any time in the earth, the sea, the air, or in the elements, pray tell me when it was. ”

“ The reality, which is most constant to this pure externality, rests satisfied with the abstract unity congenial to it. Within the organism, on the contrary, where we find the heart of the life-process, and still more openly in the medium of untrammelled reason uniformity gives way before the subjective unity of life. Nature is, no doubt, in its opposition to mind, a determinate existence external and independent; but even in her we find that uniformity only pre-eminently asserts itself where externality is the predominant principle. ”

“ We may, then, add to our experience on the assumption of a uniformity in nature; we may fill in our picture of what is and has been, as experience gives it us, in such a way as to make the whole consistent with this uniformity. ”

“ But whatever means Nature adopts, her aim is always the same—to specialise, to differentiate, to produce diversity from uniformity.
Differentiation not only raises the level of organisation; it usually also takes the direction of adaptation to particular habits of life, and this is perhaps the most fruitful cause of diversity. ”

“ We shall hold them to be so if we see them accompanied and supported by all the other circumstances which also have their spring of action in nature; for nature can only be recognized by the close and strict consistency, by the unity and uniformity of its effects. ”

“ Now, there appears nothing in the least resembling this case, in the conception of Natural Uniformity. No thinker can predicate substantial impossibility of the idea that Nature should ever be otherwise than Uniform. ”

“ We further saw that the only uniformity science requires of the actual course of nature is uniformity sufficiently close to enable us, for our special purposes, to neglect the individual deviations, and that the principle of Uniformity itself is not a logical axiom but a practical postulate, expressing the condition necessary for the successful formulation of rules for practical intervention in the course of events. ”

“ As in nature, so in society, uniformity means but too often [pg 013] stagnation, while variety is the surest sign of health and vigor. The deepest secret of nature is its love of continued novelty. Its tendency, if unrestrained, is towards constantly creating new varieties, which, if they fulfil their purpose, become fixed for a time, or, it may be, forever; while others, after they have fulfilled their purpose, vanish to make room for new and stronger types. ”

“ Unity and uniformity, within the limits imposed by progress and increasing complexity, can be affirmed of the whole process. From the dawn of life to the present time the great laws of physical nature which operate on animals and plants have been uniform. These stable laws have regulated the action of the outer world on organisms. The plans of structure of these organisms laid down at the first have been followed throughout. ”

“ We may well as philosophers admit, in consideration of the special circumstances of the case, the possibility of these supernatural facts, while prizing the principle of uniformity as a working hypothesis, or as more than this. For in truth even the action of the ordinary human will introduces strange breaches of uniformity into Nature. ”

“ We then saw that if nature consists of such sentient experiences, the apparent domination of it by absolute law and uniformity cannot be the final truth. Such uniformity as there is must be approximate, and must result from our having to deal in bulk with collections of facts which we cannot follow in their individual detail, 233and will thus be of the same type as the statistical uniformities established by the anthropological sciences in various departments of human conduct. ”

“ Uniformity is the rigorous law of nature; what once happened can happen always. ”

“ Such occasional imperfections give variety and add perfection to the whole. How dreary and monotonous would nature be, were every blade of grass, every plant, every animal, and every face we met formed after the most perfect model! ”

“ It is, however, commonly assumed that actions which are uniform are, by their very uniformity, proved to be necessitated; and that unless what happens was bound to happen, there can be no uniformity and no science. ”

“ But since both the natural varieties of mankind, and the original diversities of [Pg 512] local circumstances, are much less considerable than the points of agreement, there will naturally be a certain degree of uniformity in the progressive development of the species and of its works. And this uniformity tends to become greater, not less, as society advances ”

“ In the midst of uniformities of nature, moving at will on the plane of natural necessities, weaving the pattern of its ideas through the warp of natural laws, runs the personal life. On the same plane and amid these uniformities, yet itself a sphere of being of another order ”

“ Lastly, uniformity may be arrived at, as in most civilised countries of to-day, by continual and rapid intercourse between peoples. It is just this condition, together with a certain amount of stability in the environment, which makes for the uniformity and fixation of species in the animal world. ”

“ We must be exact, mathematical and geometrical, in order to be equal to nature. Number and fantasy, law and abundance are the feverish forces of nature; not sitting down beneath a green tree, but creating crystals and ideas denotes becoming as nature ”
