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.
Meaning of verification.
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 also. There is accordingly a sense in which myth admits substantiation of a kind that science excludes. The Olympic hierarchy might conceivably exist bodily; but gravitation and natural selection, being schemes of relation, can never exist substantially and on their own behoof. Nevertheless, the Olympic hierarchy, even if it happened to exist, could not be proved to do so unless it were a part of the natural world open to sense; while gravitation and natural selection, without being existences, can be verified at every moment by concrete events occurring as those principles require. A hypothesis, being a discursive device, gains its utmost possible validity when its discursive value is established. It is not, it merely applies; and every situation in which it is found to apply is a proof of its truth.
The case would not be different with fables, were their basis and meaning remembered. But fables, when hypostatised, forget that they, too, were transitive symbols and boast to reveal an undiscoverable reality. A dogmatic myth is in this sorry plight: that the more evidence it can find to support it the more it abrogates its metaphysical pretensions, while the more it insists on its absolute truth the less relevance it has to experience and the less meaning. To try to support fabulous dogmas by evidence is tantamount to acknowledging that they are merely scientific hypotheses, instruments of discourse, and methods of expression. But in that case their truth would no longer be supposed to lie in the fact that somewhere beyond the range of human observation they descended bodily to the plane of flying existence, and were actually enacted there. They would have ceased to resemble the society of Olympus, which to prove itself real would need to verify itself, since only the gods and those mortals admitted to their conclave could know for a fact that that celestial gathering existed. On the contrary, a speculation that could be supported by evidence would be one that might be made good without itself descending to the plane of immediacy, but would be sufficiently verified when diffuse facts fall out as it had led us to expect. The myth in such a case would have become transparent again and relevant to experience, which could continually serve to support or to correct it. Even if somewhat overloaded and poetical, it would be in essence a scientific theory. It would no longer terminate in itself; it would point forward, leading the thinker that used it to eventual facts of experience, facts which his poetic wisdom would have prepared him to meet and to use.
Possible validity of myths.
If I say, for instance, that Punishment, limping in one leg, patiently follows every criminal, the myth is obvious and innocent enough. It reveals nothing, but, what is far better, it means something. I have expressed a truth of experience and pointed vaguely to the course which events may be expected to take under given circumstances. The expression, though mythical in form, is scientific in effect, because it tends to surround a given phenomenon (the crime) with objects on its own plane—other passions and sensations to follow upon it. What would be truly mythical would be to stop at the figure of speech and maintain, by way of revealed dogma, that a lame goddess of vindictive mind actually follows every wicked man, her sword poised in mid-air. Sinking into that reverie, and trembling at its painted truth, I should be passing to the undiscoverable and forgetting the hard blows actually awaiting me in the world. Fable, detaining the mind too long in the mesh of expression, would have become metaphysical dogma. I should have connected the given fact with imagined facts, which even if by chance real—for such a goddess may, for all we know, actually float in the fourth dimension—are quite supernumerary in my world, and never, by any possibility, can become parts or extensions of the experience they are thought to explain. The gods are demonstrable only as hypotheses, but as hypotheses they are not gods.
Any dreamed-of thing might be experienced.
The same distinction is sometimes expressed by saying that science deals only with objects of possible experience. But this expression is unfortunate, because everything thinkable, no matter how mythical and supernatural or how far beyond the range of mortal senses, is an object of possible experience. Tritons and sea-horses might observe one another and might feel themselves live. The thoughts and decrees said to occupy the divine mind from all eternity would certainly be phenomena there; they would be experienced things. Were fables really as metaphysical and visionary as they pretend to be, were they not all the while and in essence mere symbols for natural situations, they would be nothing but reports about other alleged parts of experience. A real Triton, a real Creator, a real heaven would obviously be objects open to properly equipped senses and seats of much vivid experience. But a Triton after all has something to do with the Ægean and other earthly waters; a Creator has something to do with the origin of man and of his habitat; heaven has something to do with the motives and rewards of moral action. This relevance to given experience and its objects is what cuts those myths off from their blameless and gratuitous rôle of reporting experiences that might be going on merrily enough somewhere else in the universe. In calling them myths and denying that what they describe falls within the purview of science, we do not assert that, absolutely taken, they could not be objects of a possible experience. What we mean is rather that no matter how long we searched the sea waves, in which it is the essence of our Tritons to disport themselves, we should never find Tritons there; and that if we traced back the history of man and nature we should find them always passing by natural generation out of slightly different earlier forms and never appearing suddenly, at the fiat of a vehement Jehovah swimming about in a chaos; and finally that if we considered critically our motives and our ideals, we should find them springing from and directed upon a natural life and its functions, and not at all on a disembodied and timeless ecstasy. Those myths, then, while they intrinsically refer to facts in the given world, describe those facts in incongruous terms. They are symbols, not extensions, for the experience we know.
But science follows the movement of its subject-matter.
A chief characteristic of science, then, is that in supplementing given facts it supplements them by adding other facts belonging to the same sphere, and eventually discoverable by tracing the given object in its own plane through its continuous transformations. Science expands speculatively, by the aid of merely instrumental hypotheses, objects given in perception until they compose a congruous, self-supporting world, all parts of which might be observed consecutively. What a scientific hypothesis interpolates among the given facts—the atomic structure of things, for instance—might come in time under the direct fire of attention, fixed more scrupulously, longer, or with better instruments upon those facts themselves. Otherwise the hypothesis that assumed that structure would be simply false, just as a hypothesis that the interior of the earth is full of molten fire would be false if on inspection nothing were found there but solid rock. Science does not merely prolong a habit of inference; it verifies and solves the inference by reaching the fact inferred.
