To such spiritualism as this there is an easy answer, and Mr. Spencer makes it effectively. In some well-written pages at the end of the first volume of his Psychology he shows us that a 'matter' so infinitely subtile, and performing motions as inconceivably quick and fine as those which modern science postulates in her explanations, has no trace of grossness left. He shows that the conception of spirit, as we mortals hitherto have framed it, is itself too gross to cover the exquisite tenuity of nature's facts. Both terms, he says, are but symbols, pointing to that one unknowable reality in which their oppositions cease.
To an abstract objection an abstract rejoinder suffices; and so far as one's opposition to materialism springs from one's disdain of matter as something 'crass,' Mr. Spencer cuts the ground from under one. Matter is indeed infinitely and incredibly refined. To anyone who has ever looked on the face of a dead child or parent the mere fact that matter COULD have taken for a time that precious form, ought to make matter sacred ever after. It makes no difference what the PRINCIPLE of life may be, material or immaterial, matter at any rate co-operates, lends itself to all life's purposes. That beloved incarnation was among matter's possibilities.
But now, instead of resting in principles after this stagnant intellectualist fashion, let us apply the pragmatic method to the question. What do we MEAN by matter? What practical difference can it make NOW that the world should be run by matter or by spirit? I think we find that the problem takes with this a rather different character.
And first of all I call your attention to a curious fact. It makes not a single jot of difference so far as the PAST of the world goes, whether we deem it to have been the work of matter or whether we think a divine spirit was its author.
Imagine, in fact, the entire contents of the world to be once for all irrevocably given. Imagine it to end this very moment, and to have no future; and then let a theist and a materialist apply their rival explanations to its history. The theist shows how a God made it; the materialist shows, and we will suppose with equal success, how it resulted from blind physical forces. Then let the pragmatist be asked to choose between their theories. How can he apply his test if the world is already completed? Concepts for him are things to come back into experience with, things to make us look for differences. But by hypothesis there is to be no more experience and no possible differences can now be looked for. Both theories have shown all their consequences and, by the hypothesis we are adopting, these are identical. The pragmatist must consequently say that the two theories, in spite of their different-sounding names, mean exactly the same thing, and that the dispute is purely verbal. [I am opposing, of course, that the theories HAVE been equally successful in their explanations of what is.]
For just consider the case sincerely, and say what would be the WORTH of a God if he WERE there, with his work accomplished and his world run down. He would be worth no more than just that world was worth. To that amount of result, with its mixed merits and defects, his creative power could attain, but go no farther. And since there is to be no future; since the whole value and meaning of the world has been already paid in and actualized in the feelings that went with it in the passing, and now go with it in the ending; since it draws no supplemental significance (such as our real world draws) from its function of preparing something yet to come; why then, by it we take God's measure, as it were. He is the Being who could once for all do THAT; and for that much we are thankful to him, but for nothing more. But now, on the contrary hypothesis, namely, that the bits of matter following their laws could make that world and do no less, should we not be just as thankful to them? Wherein should we suffer loss, then, if we dropped God as an hypothesis and made the matter alone responsible? Where would any special deadness, or crassness, come in? And how, experience being what is once for all, would God's presence in it make it any more living or richer?
Candidly, it is impossible to give any answer to this question. The actually experienced world is supposed to be the same in its details on either hypothesis, "the same, for our praise or blame," as Browning says. It stands there indefeasibly: a gift which can't be taken back. Calling matter the cause of it retracts no single one of the items that have made it up, nor does calling God the cause augment them. They are the God or the atoms, respectively, of just that and no other world. The God, if there, has been doing just what atoms could do—appearing in the character of atoms, so to speak—and earning such gratitude as is due to atoms, and no more. If his presence lends no different turn or issue to the performance, it surely can lend it no increase of dignity. Nor would indignity come to it were he absent, and did the atoms remain the only actors on the stage. When a play is once over, and the curtain down, you really make it no better by claiming an illustrious genius for its author, just as you make it no worse by calling him a common hack.
Thus if no future detail of experience or conduct is to be deduced from our hypothesis, the debate between materialism and theism becomes quite idle and insignificant. Matter and God in that event mean exactly the same thing—the power, namely, neither more nor less, that could make just this completed world—and the wise man is he who in such a case would turn his back on such a supererogatory discussion. Accordingly, most men instinctively, and positivists and scientists deliberately, do turn their backs on philosophical disputes from which nothing in the line of definite future consequences can be seen to follow. The verbal and empty character of philosophy is surely a reproach with which we are, but too familiar. If pragmatism be true, it is a perfectly sound reproach unless the theories under fire can be shown to have alternative practical outcomes, however delicate and distant these may be. The common man and the scientist say they discover no such outcomes, and if the metaphysician can discern none either, the others certainly are in the right of it, as against him. His science is then but pompous trifling; and the endowment of a professorship for such a being would be silly.
Accordingly, in every genuine metaphysical debate some practical issue, however conjectural and remote, is involved. To realize this, revert with me to our question, and place yourselves this time in the world we live in, in the world that HAS a future, that is yet uncompleted whilst we speak. In this unfinished world the alternative of 'materialism or theism?' is intensely practical; and it is worth while for us to spend some minutes of our hour in seeing that it is so.
How, indeed, does the program differ for us, according as we consider that the facts of experience up to date are purposeless configurations of blind atoms moving according to eternal laws, or that on the other hand they are due to the providence of God? As far as the past facts go, indeed there is no difference. Those facts are in, are bagged, are captured; and the good that's in them is gained, be the atoms or be the God their cause. There are accordingly many materialists about us to-day who, ignoring altogether the future and practical aspects of the question, seek to eliminate the odium attaching to the word materialism, and even to eliminate the word itself, by showing that, if matter could give birth to all these gains, why then matter, functionally considered, is just as divine an entity as God, in fact coalesces with God, is what you mean by God. Cease, these persons advise us, to use either of these terms, with their outgrown opposition. Use a term free of the clerical connotations, on the one hand; of the suggestion of gross-ness, coarseness, ignobility, on the other. Talk of the primal mystery, of the unknowable energy, of the one and only power, instead of saying either God or matter. This is the course to which Mr. Spencer urges us; and if philosophy were purely retrospective, he would thereby proclaim himself an excellent pragmatist.
