Life and Matter.

by Oliver Lodge.

"'Attraction' and 'repulsion' seem to be the sources of _will_--that momentous element of the soul which determines the character of the individual" (p. 45).

"The positive ponderable matter, the element with the feeling of like or desire, is continually striving to complete the process of condensation, and thus collecting an enormous amount of _potential_ energy; the negative imponderable matter, on the other hand, offers a perpetual and equal resistance to the further increase of its strain and of the feeling of dislike connected therewith, and thus gathers the utmost amount of _actual_ energy.

"I think that this pyknotic theory of substance will prove more acceptable to every biologist who is convinced of the unity of nature than the kinetic theory which prevails in physics to-day"

(p. 78).

In other words, he appeals to a presumed sentiment of biologists against the knowledge of the physicist in his own sphere--a strange att.i.tude for a man of science. After this it is less surprising to find him ignoring the elementary axiom that "action and reaction are equal and opposite," _i.e._ that internal forces can have no motive power on a body as a whole, and making the grotesque a.s.sertion that matter is moved, not by external forces, but by internal likes and desires:--

"I must lay down the following theses, which are involved in Vogt's pyknotic theory, as indispensable for a truly monistic view of substance, and one that covers the whole field of organic and inorganic nature:--

"1. The two fundamental forms of substance, ponderable matter and ether, are not dead and only moved by extrinsic force, but they are endowed with sensation and will (though, naturally, of the lowest grade); they experience an inclination for condensation, a dislike of strain; they strive after the one and struggle against the other" (p. 78).

My desire is to criticise politely, and hence I refrain from characterising this sentence as a physicist should.

"Every shade of inclination, from complete indifference to the fiercest pa.s.sion, is exemplified in the chemical relation of the various elements towards each other" (p. 79).

"On those phenomena we base our conviction that even the _atom_ is not without a rudimentary form of sensation and will, or, as it is better expressed, of feeling (_aesthesis_) and inclination (_tropesis_)--that is, a universal 'soul' of the simplest character" (p. 80).

"I gave the outlines of _cellular_ psychology in 1866 in my paper on 'Cell-souls and Soul-cells'" (p. 63).

Thus, then, in order to explain life and mind and consciousness by means of matter, all that is done is to a.s.sume that matter possesses these unexplained attributes.

What the full meaning of that may be, and whether there be any philosophic justification for any such idea, is a matter on which I will not now express an opinion; but, at any rate, as it stands, it is not science, and its formulation gives no sort of conception of what life and will and consciousness really are.

Even if it were true, it contains nothing whatever in the nature of explanation: it recognises the inexplicable, and relegates it to the atoms, where it seems to hope that further quest may cease. Instead of tackling the difficulty where it actually occurs; instead of a.s.sociating life, will, and consciousness with the organisms in which they are actually in experience found, these ideas are foisted into the atoms of matter; and then the properties which have been conferred on the atoms are denied in all essential reality to the fully developed organisms which those atoms help to compose!

I show later on (Chapters V. and X.) that there is no necessary justification for a.s.suming that a phenomenon exhibited by an aggregate of particles must be possessed by the ingredients of which it is composed; on the contrary, wholly new properties may make their appearance simply by aggregation; though I admit that such a proposition is by no means obvious, and that it may be a legitimate subject for controversy. But into that question our author does not enter; and even when he has conferred on the atoms these astounding properties, he abstains from what would seem a natural development: for his doctrine is that our power is actually less than that of the atoms,--that instead of utilising the attractions and repulsions, or "likes and dislikes," of our const.i.tuent particles, and directing them by the aggregate of conscious will-power to some preconceived end, we ourselves, on the contrary, are dominated and controlled by _them_; so that freedom of the will is an illusion.

Freedom being thus disposed of, Immortality presents no difficulty; a soul is the operation of a group of cells, and so the existence of man clearly begins and ends with that of his terrestrial body:--

"The most important moment in the life of every man, as in that of all other complex animals, is the moment in which he begins his individual existence [coalescence of sperm cell and ovum] ... the existence of the personality, the independent individual, commences. This ontogenetic fact is supremely important, for the most far-reaching conclusions may be drawn from it. In the first place, we have a clear perception that man, like all the other complex animals, inherits all his personal characteristics, bodily and mental, from his parents; and further, we come to the momentous conclusion that the new personality which arises thus can lay no claim to 'immortality'" (p. 22).

Others beside Haeckel have held this kind of view at one time or another; but, unlike him, most of them have recanted and seen the error of their ways. He is, indeed, aware that several of his great German contemporaries have been through this phase of thought and come out on the other side, notably the physiologist-philosopher Wundt, and he refers to them fairly and instructively thus:--

"What seems to me of special importance and value in Wundt's work is that he 'extends the law of the persistence of force for the first time to the psychic world.'

"Thirty years afterwards, in a second edition, Wundt emanc.i.p.ated himself from the fundamental errors of the first, and says that he 'learned many years ago to consider the work a sin of his youth'; it 'weighed on him as a kind of crime, from which he longed to free himself as soon as possible.' In the first, psychology is treated as a _physical_ science, on the same laws as the whole of physiology, of which it is only a part; thirty years afterwards he finds psychology to be a _spiritual_ science, with principles and objects entirely different from those of physical science.

"I myself," says Haeckel, "naturally consider the 'youthful sin' of the young physiologist Wundt to be a correct knowledge of nature, and energetically defend it against the antagonistic view of the old philosopher Wundt. This entire change of philosophical principles, which we find in Wundt, as we found it in Kant, Virchow, du Bois-Reymond, Carl Ernst Baer, and others, is very interesting" (p. 36).

So it is: very interesting!

Professor Haeckel is so imbued with biological science that he loses his sense of proportion; and his enthusiasm for the work of Darwin leads him to attribute to it an exaggerated scope, and enables him to eliminate the third of the Kantian trilogy:--

"Darwin's theory of the natural origin of species at once gave us the solution of the mystic 'problem of creation,' the great 'question of all questions'--the problem of the true character and origin of man himself" (p. 28) [_cf._ p. 19 above].

It is a great deal more than that patient observer and deep thinker Charles Darwin ever claimed, nor have his wiser disciples claimed it for him. It is familiar that he explained how variations once arisen would be clinched, if favourable in the struggle, by the action of heredity and survival; but the source or origin of the variations themselves he did not explain.

Do they arise by guidance or by chance? Is natural selection akin to the verified and practical processes of artificial selection? or is it wholly alien to them and influenced by chance alone? The latter view can hardly be considered a complete explanation, though it is verbally the one adopted by Professor Haeckel, and it is of interest to see what he means by chance:--

"Since impartial study of the evolution of the world teaches us that there is no definite aim and no special purpose to be traced in it, there seems to be no alternative but to leave everything to 'blind chance.'

"One group of philosophers affirms, in accordance with its teleological conception, that the whole cosmos is an orderly system, in which every phenomenon has its aim and purpose; there is no such thing as chance. The other group, holding a mechanical theory, expresses itself thus: The development of the universe is a monistic mechanical process, in which we discover no aim or purpose whatever; what we call design in the organic world is a special result of biological agencies; neither in the evolution of the heavenly bodies nor in that of the crust of our earth do we find any trace of a controlling purpose--all is the result of chance.

Each party is right--according to its definition of chance. The general law of causality, taken in conjunction with the law of substance, teaches us that every phenomenon has a mechanical cause; in this sense there is no such thing as chance. Yet it is not only lawful, but necessary, to retain the term for the purpose of expressing the simultaneous occurrence of two phenomena, which are not causally related to each other, but of which each has its own mechanical cause, independent of that of the other.

"Everybody knows that chance, in this monistic sense, plays an important part in the life of man and in the universe at large.

That, however, does not prevent us from recognising in each 'chance' event, as we do in the evolution of the entire cosmos, the universal sovereignty of nature's supreme law, _the law of substance_" (p. 97).

_Illegitimate Negations._

With regard to the possibility of Revelation, or information derived from super-human sources, naturally he ridicules the idea; but in connection with the mode of origin and development of life on this planet he makes the following sensible and noteworthy admission:--

"It is very probable that these processes have gone on likewise on other planets, and that other planets have produced other types of the higher plants and animals, which are unknown on our earth; perhaps from some higher animal stem, which is superior to the vertebrate in formation, higher beings have arisen who far transcend us earthly men in intelligence."

Exactly; it is quite probable. It is, in fact, improbable that man is the highest type of existence. But if Professor Haeckel is ready to grant that probability or even possibility, why does he so strenuously exclude the idea of revelation, _i.e._, the acquiring of imparted information from higher sources? Savages can certainly have "revelation" from civilised men. Why, then, should it be inconceivable that human beings should receive information from beings in the universe higher than themselves? It may or may not be the case that they do; but there is no scientific ground for dogmatism on the subject, nor any reason for a.s.serting the inconceivability of such a thing.

Professor Haeckel would no doubt reply to some of the above criticism that he is not only a man of science, but also a philosopher, that he is looking ahead, beyond ascertained fact, and that it is his philosophic views which are in question rather than his scientific statements. To some extent it is both, as has been seen; but if even the above be widely known--if it be generally understood that the most controversial portions of his work are mainly speculative and hypothetical, it can be left to its proper purpose of doing good rather than harm. It can only do harm by misleading, it can do considerable good by criticising and stimulating and informing; and it is an interesting fact that a man so well acquainted with biology as Professor Haeckel is should have been so strongly impressed with the truth of some aspect of the philosophic system known as Monism. Many men of science have likewise been impressed with the probability, or possibility, of some such ultimate unification.

The problem to be solved--and an old-world problem indeed it is--is the range, and especially the nature, of the connection between mind and matter; or, let us say, between the material universe on the one hand, and the vital, the mental, the conscious and spiritual universe or universes, on the other.

It would be extremely surprising if any attempt yet made had already been thoroughly successful, though the attack on the idealistic side appears to many of us physicists to be by far the most hopeful line of advance. An excessively wide knowledge of existence would seem to be demanded for the success of any such most ambitious attempt; but, though none of us may hope to achieve it, many may strive to make some contribution towards the great end; and those who think they have such a contribution to make, or such a revelation entrusted to them, are bound to express it to the best of their ability, and leave it to their contemporaries and successors to a.s.similate such portions of it as are true, and to develop it further. From this point of view Professor Haeckel is no doubt amply justified in his writings; but, unfortunately, it appears to me that although he has been borne forward on the advancing wave of monistic philosophy, he has, in its specification, attempted such precision of materialistic detail, and subjected it to so narrow and limited a view of the totality of experience, that the progress of thought has left him, as well as his great English exemplar, Herbert Spencer, somewhat high and dry, belated and stranded by the tide of opinion which has now begun to flow in another direction. He is, as it were, a surviving voice from the middle of the nineteenth century; he represents, in clear and eloquent fashion, opinions which then were prevalent among many leaders of thought--opinions which they themselves in many cases, and their successors still more, lived to outgrow; so that by this time Professor Haeckel's voice is as the voice of one crying in the wilderness, not as the pioneer or vanguard of an advancing army, but as the despairing shout of a standard-bearer, still bold and unflinching, but abandoned by the retreating ranks of his comrades as they march to new orders in a fresh and more idealistic direction.

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 a.s.sertions, but on its negations. In so far as it makes positive a.s.sertions, 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 formulae 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 p.r.o.nounced 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 pa.s.sage 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:--
