REASON IN SCIENCE CHAPTER ITYPES AND AIMS OF SCIENCE
Science is so new a thing and so far from final, it seems to the layman so hopelessly accurate and extensive, that a moralist may well feel some diffidence in trying to estimate its achievements and promises at their human worth. The morrow may bring some great revolution in science, and is sure to bring many a correction and many a surprise. Religion and art have had their day; indeed a part of the faith they usually inspire is to believe that they have long ago revealed their secret. A critic may safely form a judgment concerning them; for even if he dissents from the orthodox opinion and ventures to hope that religion and art may assume in the future forms far nobler and more rational than any they have hitherto worn, still he must confess that art and religion have had several turns at the wheel; they have run their course through in various ages and climes with results which anybody is free to estimate if he has an open mind and sufficient interest in the subject. Science, on the contrary, which apparently cannot exist where intellectual freedom is denied, has flourished only twice in recorded times: once for some three hundred years in ancient Greece, and again for about the same period in modern Christendom. Its fruits have scarcely begun to appear; the lands it is discovering have not yet been circumnavigated, and there is no telling what its ultimate influence will be on human practice and feeling.
The first period in the life of science was brilliant but ineffectual. The Greeks' energy and liberty were too soon spent, and the very exuberance of their genius made its expression chaotic. Where every mind was so fresh and every tongue so clever no scientific tradition could arise, and no laborious applications could be made to test the value of rival notions and decide between them. Men of science were mere philosophers. Each began, not where his predecessor had ended, but at the very beginning. Another circumstance that impeded the growth of science was the forensic and rhetorical turn proper to Greek intelligence. This mental habit gave a tremendous advantage in philosophy to the moralist and poet over the naturalist or mathematician. Hence what survived in Greece after the heyday of theoretic achievement was chiefly philosophies of life, and these—at the death of liberty—grew daily more personal and ascetic. Authority in scientific matters clung chiefly to Plato and Aristotle, and this not for the sake of their incomparable moral philosophy—for in ethics that decadent age preferred the Stoics and Epicureans—but just for those rhetorical expedients which in the Socratic school took the place of natural science. Worse influences in this field could hardly be imagined, since Plato's physics ends in myth and apologue, while Aristotle's ends in nomenclature and teleology.
All that remained of Greek physics, therefore, was the conception of what physics should be—a great achievement due to the earlier thinkers—and certain hints and guesses in that field. The elements of geometry had also been formulated, while the Socratic school bequeathed to posterity a well-developed group of moral sciences, rational in principle, but destined to be soon overlaid with metaphysical and religious accretions, so that the dialectical nerve and reasonableness of them were obliterated, and there survived only miscellaneous conclusions, fragments of wisdom built topsy-turvy into the new mythical edifice. It is the sad task reserved for historical criticism to detach those sculptured stones from the rough mass in which they have been embedded and to rearrange them in their pristine order, thus rediscovering the inner Socratic principle of moral philosophy, which is nothing but self-knowledge—a circumspect, systematic utterance of the speaker's mind, disclosing his implicit meaning and his ultimate preferences.
At its second birth science took a very different form. It left cosmic theories to pantheistic enthusiasts like Giordano Bruno, while in sober laborious circles it confined itself to specific discoveries—the earth's roundness and motion about the sun, the laws of mechanics, the development and application of algebra, the invention of the calculus, and a hundred other steps forward in various disciplines. It was a patient siege laid to the truth, which was approached blindly and without a general, as by an army of ants; it was not stormed imaginatively as by the ancient Ionians, who had reached at once the notion of nature's dynamic unity, but had neglected to take possession in detail of the intervening tracts, whence resources might be drawn in order to maintain the main position.
Nevertheless, as discoveries accumulated, they fell insensibly into a system, and philosophers like Descartes and Newton arrived at a general physics. This physics, however, was not yet meant to cover the whole existent world, or to be the genetic account of all things in their system. Descartes excluded from his physics the whole mental and moral world, which became, so far as his science went, an inexplicable addendum. Similarly Newton's mechanical principles, broad as they were, were conceived by him merely as a parenthesis in theology. Not until the nineteenth century were the observations that had been accumulated given their full value or in fact understood; for Spinoza's system, though naturalistic in spirit, was still dialectical in form, and had no influence on science and for a long time little even on speculation.
Indeed the conception of a natural order, like the Greek cosmos, which shall include all existences—gods no less than men, if gods actually exist—is one not yet current, although it is implied in every scientific explanation and is favoured by two powerful contemporary movements which, coming from different quarters, are leading men's minds back to the same ancient and obvious naturalism. One of these movements is the philosophy of evolution, to which Darwin gave such an irresistible impetus. The other is theology itself, where it has been emancipated from authority and has set to work to square men's conscience with history and experience. This theology has generally passed into speculative idealism, which under another name recognises the universal empire of law and conceives man's life as an incident in a prodigious natural process, by which his mind and his interests are produced and devoured. This "idealism" is in truth a system of immaterial physics, like that of Pythagoras or Heraclitus. While it works with fantastic and shifting categories, which no plain naturalist would care to use, it has nothing to apply those categories to except what the naturalist or historian may already have discovered and expressed in the categories of common prose. German idealism is a translation of physical evolution into mythical language, which presents the facts now in the guise of a dialectical progression, now in that of a romantic drama. In either case the facts are the same, and just those which positive knowledge has come upon. Thus many who are not brought to naturalism by science are brought to it, quite unwillingly and unawares, by their religious speculations.
The gulf that yawns between such idealistic cosmogonies and a true physics may serve to make clear the divergence in principle which everywhere divides natural science from arbitrary conceptions of things. This divergence is as far as possible from lying in the merit of the two sorts of theory. Their merit, and the genius and observation required to frame them, may well be equal, or an imaginative system may have the advantage in these respects. It may even be more serviceable for a while and have greater pragmatic value, so long as knowledge is at best fragmentary, and no consecutive or total view of things is attempted by either party. Thus in social life a psychology expressed in terms of abstract faculties and personified passions may well carry a man farther than a physiological psychology would. Or, again, we may say that there was more experience and love of nature enshrined in ancient mythology than in ancient physics; the observant poet might then have fared better in the world than the pert and ignorant materialist. Nor does the difference between science and myth lie in the fact that the one is essentially less speculative than the other. They are differently speculative, it is true, since myth terminates in unverifiable notions that might by chance represent actual existences; while science terminates in concepts or laws, themselves not possibly existent, but verified by recurring particular facts, belonging to the same experience as those from which the theory started.
The laws formulated by science—the transitive figments describing the relation between fact and fact—possess only a Platonic sort of reality. They are more real, if you will, than the facts themselves, because they are more permanent, trustworthy, and pervasive; but at the same time they are, if you will, not real at all, because they are incompatible with immediacy and alien to brute existence. In declaring what is true of existences they altogether renounce existence on their own behalf. This situation has made no end of trouble in ill-balanced minds, not docile to the diversities and free complexity of things, but bent on treating everything by a single method. They have asked themselves persistently the confusing question whether the matter or the form of things is the reality; whereas, of course, both elements are needed, each with its incommensurable kind of being. The material element alone is existent, while the ideal element is the sum of all those propositions which are true of what exists materially. Anybody's knowledge of the truth, being a complex and fleeting feeling, is of course but a moment of existence or material being, which whether found in God or man is as far as possible from being that truth itself which it may succeed in knowing.
The true contrast between science and myth is more nearly touched when we say that science alone is capable of verification. Some ambiguity, however, lurks in this phrase, since verification comes to a method only vicariously, when the particulars it prophesies are realised in sense. To verify a theory as if it were not a method but a divination of occult existences would be to turn the theory into a myth and then to discover that what the myth pictured had, by a miracle, an actual existence
