3. Nature-searchers.
The discovery of regular processes, of expected effects following upon specified antecedents, of constant properties and qualities in the material around him, has from the earliest recorded times been a chief occupation of Man and has led to the attainment by Man of an extraordinarily complex control of the conditions in which his life is carried on. But it was not until Bruno’s conception of the unity of terrestrial nature with that of the kosmos had commended itself that a deliberate and determined investigation of natural processes, with a view to their more complete apprehension, was instituted. One of the earliest and most active steps in this direction was the foundation, less than 250 years ago, of the Royal Society of London for the Promotion of Natural Knowledge, by a body of students who had organized their conferences and inquiries whilst resident in Oxford.[1]
All over Western Europe such associations or academies for the building up of the New Philosophy (as it was called here) came into existence. It is a fact which is strangely overlooked at the present day, when the assumption is made that the acquirement of a knowledge of Greek grammar is the traditional and immemorial occupation of Oxford students—that until the modern days of the eighteenth century (‘modern’ in the history of Oxford) Greek was less known in Oxford than Hebrew is at present, and that the study of Nature—Nature-knowledge and Nature-control—was the appropriate occupation of her learned men. It is indeed a fact that the very peculiar classical education at present insisted on in Oxford, and imposed by her on the public schools of the country, is a modern innovation, an unintentional and, in a biological sense, ‘morbid’ outgrowth of that ‘Humanism’ to which a familiarity with the dead languages was, but is no longer, the pathway.
4. The Doctrine of Evolution.
What is sometimes called the scientific movement, but may be more appropriately described as the Nature-searching movement, rapidly attained an immense development. In the latter half of the last century this culminated in so complete a knowledge of the movements of the heavenly bodies, their chemical nature and physical condition—so detailed a determination of the history of the crust of this earth and of the living things upon it, of the chemical and physical processes which go on in Man and other living things, and of the structure of Man as compared with the animals most like him, and of the enormous length of time during which Man has existed on the earth—that it became possible to establish a general doctrine of the evolution of the kosmos, with more special detail in regard to the history of this earth and the development of Man from a lower animal ancestry. Animals were, in their turn, shown to have developed from simplest living matter, and this from less highly elaborated compounds of chemical ‘elements’ differentiated at a still earlier stage of evolution. There is, it may be said without exaggeration, no school or body of thinkers at the present day who are acquainted with the facts now ascertained, which denies the orderly evolution of the kosmos by the regular operation of a more or less completely ascertained series of properties resident in the material of which it consists.[2] The process of evolution—the interaction of these ascertainable, if not fully ascertained properties—has led (it is held), in the case of the cooling cinder which we call the earth—by an inevitable and predestined course—to the formation of that which we call living matter and eventually of Man himself. From this process all disorderly or arbitrary interferences must, it seems, be excluded. The old fancies as to presiding demons or fairies—which it was imagined had for their business to interrupt the supposed feeble and limited efforts of Nature, as yet unexplored and unappreciated—have passed out of mind. The consensus is complete: Man is held to be a part of Nature, a product of the definite and orderly evolution which is universal; a being resulting from and driven by the one great nexus of mechanism which we call Nature. He stands alone, face to face with that relentless mechanism. It is his destiny to understand and to control it.
5. Unwarranted inferences from the Evolution of Man.
There are not wanting those who, accepting this conclusion, seek to belittle Man and endeavour to represent that the veil is lifted, that all is ‘explained’ obvious, commonplace, and mean in regard to the significance of life and of Man, because it has become clear that the kosmic process has brought them forth in due order. There are others who rightly perceive that life is no common property of our cooling matter, but unique and exceptional, and that Man stands apart from and above all natural products, whether animate or inanimate. Some of these thinkers appear to accept the conclusion that if life and Man are regarded as products of the kosmic process—that is, of Nature—‘life’ and ‘Man’ lose so much in importance and significance that dire consequences must follow to Man’s conception of his dignity and to the essential features of his systems of conduct and social organization. Accordingly they cling to the belief that living matter and Man have not proceeded from an orderly evolution of Nature, but are ‘super’ natural. It is found on the other hand, by many who have considered these speculations, and hold no less explicitly than do the ‘supernaturalists’ that life is a momentous and peculiar feature of our earth’s surface and Man the isolated and unparalleled ‘piece of work,’ ‘the beauty of the world,’ ‘the paragon of animals’—it is found by many such, I say, that nothing is gained in regard to our conception of Man’s nobility and significance by supposing that he and the living matter which has given rise to him, are not the outcome of that system of orderly process which we call Nature.
There is one consideration in regard to this matter which, it seems, is often overlooked and should be emphasized. It is sometimes—and perhaps with a sufficient excuse in a want of acquaintance with Nature—held by those who oppose the conclusion that Man has been evolved by natural processes, that the products of Nature are arbitrary, haphazard, and due to chance, and that Man cannot be conceived of as originating by chance. This notion of ‘chance’ is a misleading figment inherited by the modern world from days of blank ignorance. The ‘Nature-searchers’ of to-day admit no such possibility as ‘chance.’ It will be in the recollection of many here, that a leading writer and investigator of the Victorian Era, the physicist John Tyndall, pointed out in a celebrated address delivered at Belfast that according to the conceptions of the mechanism of Nature arrived at by modern science—the structure of that mechanism is such that it would have been possible for a being of adequate intelligence inspecting the gaseous nebula from which our planetary system has evolved to have foreseen in that luminous vapour the Belfast audience and the professor addressing it!
