CHAPTER IV

MEMORANDA FOR WOULD-BE MATERIALISTS

The objection which it has been found necessary to express concerning Materialism as a complete system is based not on its assertions, but on its negations. In so far as it makes positive assertions, embodying the results of scientific discovery and even of scientific speculation based thereupon, there is no fault to find with it; but when, on the strength of that, it sets up to be a philosophy of the universe—all inclusive, therefore, and shutting out a number of truths otherwise perceived, or which appeal to other faculties, or which are equally true and are not really contradictory of legitimately materialistic statements—then it is that its insufficiency and narrowness have to be displayed.

It will be probably instructive, and it may be sufficient, if I show that two great leaders in scientific thought (one the greatest of all men of science who have yet lived), though well aware of much that could be said positively on the materialistic side, and very willing to admit or even to extend the province of science or exact knowledge to the uttermost, yet were very far from being philosophic Materialists or from imagining that other modes of regarding the universe were thereby excluded.

Great leaders of thought, in fact, are not accustomed to take a narrow view of existence, or to suppose that one mode of regarding it, or one set of formulæ expressing it, can possibly be sufficient and complete. Even a sheet of paper has two sides: a terrestrial globe presents different aspects from different points of view; a crystal has a variety of facets; and the totality of existence is not likely to be more simple than any of these—is not likely to be readily expressible in any form of words, or to be thoroughly conceivable by any human mind.

It may be well to remember that Sir Isaac Newton was a Theist of the most pronounced and thorough conviction, although he had a great deal to do with the reduction of the major Cosmos to mechanics, _i.e._ with its explanation by the elaborated machinery of simple forces; and he conceived it possible that, in the progress of science, this process of reduction to mechanics would continue till it embraced nearly all phenomena. (See extract below.) That, indeed, has been the effort of science ever since, and therein lies the legitimate basis for materialistic statements, though not for a materialistic philosophy.

The following sound remarks concerning Newton are taken from Huxley's _Hume_, p. 246:—

"Newton demonstrated all the host of heaven to be but the elements of a vast mechanism, regulated by the same laws as those which express the falling of a stone to the ground. There is a passage in the preface to the first edition of the _Principia_, which shows that Newton was penetrated, as completely as Descartes, with the belief that all the phenomena of nature are expressible in terms of matter and motion:—

"'WOULD THAT THE REST OF THE PHENOMENA OF NATURE COULD BE DEDUCED BY A LIKE KIND OF REASONING FROM MECHANICAL PRINCIPLES. FOR MANY CIRCUMSTANCES LEAD ME TO SUSPECT THAT ALL THESE PHENOMENA MAY DEPEND UPON CERTAIN FORCES, IN VIRTUE OF WHICH THE PARTICLES OF BODIES, BY CAUSES NOT YET KNOWN, ARE EITHER MUTUALLY IMPELLED AGAINST ONE ANOTHER, AND COHERE INTO REGULAR FIGURES, OR REPEL AND RECEDE FROM ONE ANOTHER; WHICH FORCES BEING UNKNOWN, PHILOSOPHERS HAVE AS YET EXPLORED NATURE IN VAIN. BUT I HOPE THAT, EITHER BY THIS METHOD OF PHILOSOPHISING, OR BY SOME OTHER AND BETTER, THE PRINCIPLES HERE LAID DOWN MAY THROW SOME LIGHT UPON THE MATTER.'"

Here is a full-blown anticipation of an intelligible exposition of the Universe in terms of matter and force: the substantial basis of what smaller men call materialism and develop into what they consider to be a materialistic philosophy. But there is no necessity for anything of the kind; a systematic expression of facts in terms of one of their aspects does not exclude expression in terms of other and totally different aspects also. Denial of all sides but one, is a poor kind of unification. Denial of this sort is the weakness and delusion of the people who call themselves 'Christian Scientists': they have hold of one side of truth—and that should be granted them,—but they hold it in so narrow and insecure a fashion that, in self-defence, they think it safest strenuously to deny the existence of all other sides. In this futile enterprise they are imitating the attitude of the philosophic Materialists, on the other side of the controversy.

And then, again, Professor Huxley himself, who is commonly spoken of by half-informed people as if he were a philosophic materialist, was really nothing of the kind; for although, like Newton, fully imbued with the mechanical doctrine, and, of course, far better informed concerning the biological departments of Nature and the discoveries which have in the last century been made, and though he rightly regarded it as his mission to make the scientific point of view clear to his benighted contemporaries, and was full of enthusiasm for the facts on which materialists take their stand, he saw clearly that these alone were insufficient for a philosophy. The following extracts from the 'Hume' volume will show, first, that he entirely repudiated materialism as a satisfactory or complete scheme of things; and, secondly, that he profoundly disagreed with the position which now appears to be occupied by Professor Haeckel. Especially is he severe on gratuitous denials applied to provinces beyond our scope, saying:—

"that while it is the summit of human wisdom to learn the limit of our faculties, it may be wise to recollect that we have no more right to make denials, than to put forth affirmatives, about what lies beyond that limit. Whether either mind or matter has a 'substance' or not is a problem which we are incompetent to discuss; and it is just as likely that the common notions upon the subject should be correct as any others.... 'The same principles which, at first view, lead to scepticism, pursued to a certain point, bring men back to common sense'" (p. 282).

And on p. 286 he speaks concerning "substance"—that substance which constitutes the foundation of Haeckel's philosophy—almost as if he were purposely confuting that rather fly-blown production:—

"Thus, if any man think he has reason to believe that the '_substance_' of matter, to the existence of which no limit can be set either in time or space, is the infinite and eternal substratum of all actual and possible existences, which is the doctrine of philosophical materialism, as I understand it, I have no objection to his holding that doctrine; and I fail to comprehend how it can have the slightest influence upon any ethical or religious views he may please to hold....

"Moreover, the ultimate forms of existence which we distinguish in our little speck of the universe are, possibly, only two out of infinite varieties of existence, not only analogous to matter and analogous to mind, but of kinds which we are not competent so much as to conceive—in the midst of which, indeed, we might be set down, with no more notion of what was about us, than the worm in a flower-pot, on a London balcony, has of the life of the great city.

"That which I do very strongly object to is the habit, which a great many non-philosophical materialists unfortunately fall into, of forgetting all these very obvious considerations. They talk as if the proof that the 'substance of matter' was the 'substance' of all things cleared up all the mysteries of existence. In point of fact, it leaves them exactly where they were.... Your religious and ethical difficulties are just as great as mine. The speculative game is drawn—let us get to practical work" (p. 286).

And again on pp. 251 and 279:—

"It is worth any amount of trouble to ... know by one's own knowledge the great truth ... that the honest and rigorous following up of the argument which leads us to 'materialism' inevitably carries us beyond it" (p. 251).

"To sum up. If the materialist affirms that the universe and all its phenomena are resolvable into matter and motion, Berkeley replies, True; but what you call matter and motion are known to us only as forms of consciousness; their being is to be conceived or known; and the existence of a state of consciousness, apart from a thinking mind, is a contradiction in terms.

"I conceive that this reasoning is irrefragable. And, therefore, if I were obliged to choose between absolute materialism and absolute idealism, I should feel compelled to accept the latter alternative" (p. 279).

Let the jubilant but uninstructed and comparatively ignorant amateur materialist therefore beware, and bethink himself twice or even thrice before he conceives that he understands the universe and is competent to pour scorn upon the intuitions and perceptions of great men in what may be to him alien regions of thought and experience.

Let him explain, if he can, what he means by his own identity, or the identity of any thinking or living being, which at different times consists of a totally different set of material particles. Something there clearly is which confers personal identity and constitutes an individual: it is a property characteristic of every form of life, even the humblest; but it is not yet explained or understood, and it is no answer to assert gratuitously that there is some fundamental "substance" or material basis on which that identity depends, any more than it is an explanation to say that it depends upon a "soul." These are all forms of words. As Hume says, quoted by Huxley with approval in the work already cited, p. 194:—

"It is impossible to attach any definite meaning to the word 'substance,' when employed for the hypothetical substratum of soul and matter.... If it be said that our personal identity requires the assumption of a substance which remains the same while the accidents of perception shift and change, the question arises what is meant by personal identity?... A plant or an animal, in the course of its existence, from the condition of an egg or seed to the end of life, remains the same neither in form, nor in structure, nor in the matter of which it is composed: every attribute it possesses is constantly changing, and yet we say that it is always one and the same individual" (p. 194).

And in his own preface to the 'Hume' volume Huxley expresses himself forcibly thus,—equally antagonistic as was his wont to both ostensible friend and ostensible foe, as soon as they got off what he considered the straight path:—

"That which it may be well for us not to forget is, that the first-recorded judicial murder of a scientific thinker [Socrates] was compassed and effected, not by a despot, nor by priests, but was brought about by eloquent demagogues.... Clear knowledge of what one does not know just as important as knowing what one does know....

"The development of exact natural knowledge in all its vast range, from physics to history and criticism, is the consequence of the working out, in this province, of the resolution to 'take nothing for truth without clear knowledge that it is such'; to consider all beliefs open to criticism; to regard the value of authority as neither greater nor less, than as much as it can prove itself to be worth. The modern spirit is not the spirit 'which always denies,' delighting only in destruction; still less is it that which builds castles in the air rather than not construct; it is that spirit which works and will work 'without haste and without rest,' gathering harvest after harvest of truth into its barns, and devouring error with unquenchable fire" (p. viii.).

The harvesting of truth is a safe enough enterprise, but the devouring of error is a more dangerous pastime, since flames are liable to spread beyond our control; and though, in a world overgrown with weeds and refuse, the cleansing influence of fire is a necessity, it would be cruel to apply the same agency again at a later stage, when a fresh young crop is springing up in the cleared ground.
