Scientific And Pseudo-Scientific Realism
by
I repeat that, if imagination is used within the limits laid down by science, disorder is unimaginable. If a being endowed with perfect intellectual and aesthetic faculties, but devoid of the capacity for suffering pain, either physical or moral, were to devote his utmost powers to the investigation of nature, the universe would seem to him to be a sort of kaleidoscope, in which, at every successive moment of time, a new arrangement of parts of exquisite beauty and symmetry would present itself; and each of them would show itself to be the logical consequence of the preceding arrangement, under the conditions which we call the laws of nature. Such a spectator might well be filled with that Amor intellectualis Dei, the beatific vision of the vita contemplativa, which some of the greatest thinkers of all ages, Aristotle, Aquinas, Spinoza, have regarded as the only conceivable eternal felicity; and the vision of illimitable suffering, as if sensitive beings were unregarded animalcules which had got between the bits of glass of the kaleidoscope, which mars the prospect to us poor mortals, in no wise alters the fact that order is lord of all, and disorder only a name for that part of the order which gives us pain.
The other fallacious employment of the names of scientific conceptions which pervades the preacher’s utterance, brings me back to the proper topic of the present essay. It is the use of the word “law” as if it denoted a thing–as if a “law of nature,” as science understands it, were a being endowed with certain powers, in virtue of which the phenomena expressed by that law are brought about. The preacher asks, “Might not there be a suspension of a lower law by the intervention of a higher?” He tells us that every time we lift our arms we defy the law of gravitation. He asks whether some day certain “royal and ultimate laws” may not come and “wreck” those laws which are at present, it would appear, acting as nature’s police. It is evident, from these expressions, that “laws,” in the mind of the preacher, are entities having an objective existence in a graduated hierarchy. And it would appear that the “royal laws” are by no means to be regarded as constitutional royalties: at any moment, they may, like Eastern despots, descend in wrath among the middle-class and plebeian laws, which have hitherto done the drudgery of the world’s work, and, to use phraseology not unknown in our seats of learning–“make hay” of their belongings. Or perhaps a still more familiar analogy has suggested this singular theory; and it is thought that high laws may “suspend” low laws, as a bishop may suspend a curate.
Far be it from me to controvert these views, if any one likes to hold them. All I wish to remark is that such a conception of the nature of “laws” has nothing to do with modern science. It is scholastic realism–realism as intense and unmitigated as that of Scotus Erigena a thousand years ago. The essence of such realism is that it maintains the objective existence of universals, or, as we call them nowadays, general propositions. It affirms, for example, that “man” is a real thing, apart from individual men, having its existence, not in the sensible, but in the intelligible world, and clothing itself with the accidents of sense to make the Jack and Tom and Harry whom we know. Strange as such a notion may appear to modern scientific thought, it really pervades ordinary language. There are few people who would, at once, hesitate to admit that colour, for example, exists apart from the mind which conceives the idea of colour. They hold it to be something which resides in the coloured object; and so far they are as much Realists as if they had sat at Plato’s feet. Reflection on the facts of the case must, I imagine, convince every one that “colour” is–not a mere name, which was the extreme Nominalist position–but a name for that group of states of feeling which we call blue, red, yellow, and so on, and which we believe to be caused by luminiferous vibrations which have not the slightest resemblance to colour; while these again are set afoot by states of the body to which we ascribe colour, but which are equally devoid of likeness to colour.
