Rebirth, Evolution, Heredity

TWO TRUTHS, discoveries with an enormous periphery of luminous result and of a considerable essential magnitude, evolution and heredity, figure today in the front of thought, and I suppose we have to take them as a well-established unquenchable light upon our being, lamps of a constant lustre, though not yet very perfectly trimmed, final so far as anything is final in man's constantly changing cinematographic process of the development of intellectual knowledge They may be said to make up almost the whole fundamental idea of life in the way of seeing peculiar to a mind dominated, fashioned, pressed into its powerful moulds by the exact, curious, multifariously searching, yet in the end singularly limited observation and singularly narrow reason of our modern science . Science is in her own way a great seer and magician; she has both the microscopic and the macroscopic, the closely gazing and the telescopic view, a dissolving power of searching analytic resolution, a creative power of revealing synthetic effectuation She has hunted to their lair many of the intermediate secret processes of the great creatrix, and even she has been able, by the inventive faculty given to us, to go and do one better Man, this midget in infinity, locomotive yet nailed to the contiguity of a petty crust of soil by the force of gravitation, has certainly scored by her a goodly number of points against the mother of the universe But all this has been done in some perfection only in the limits of her lowest obtrusive physical field.

Face to face with psychic and spiritual secrecies, as in the open elementary world even of mind, Science has still the uninformed gaze and the groping hands of the infant In that sphere she, so precise, illuminative, compelling in the physical, sees only the big blazing buzzing confusion which James tells us, with a possibly inaccurate vividness of alliterative phrase, is

the newborn baby's view of the sensible world into which he has dropped down the mysterious stairs of birth Science, faced with what are still to her the wonderful random accords and unexplained miracles of consciousness, protects herself from the errors of the imagination, —but stumbling incidentally by that very fact into plenty of the errors of an inadequate induction, —behind an opaque shield of cautelous scepticism She clings with the grasping firmness of the half-drowned to planks of security she thinks she has got in a few well-tested correspondences, —so-styled, though the word as used explains nothing, —between mental action and its accompaniment of suggestive or instrumental physical functionings She is determined, if she can, to explain every supraphysical phenomenon by some physical fact; psychological process of mind must not exist except as result or rendering of physiological process of body This set resolution, apparently rational and cautious of ascertainable and firmly tangible truth, but really heroic in its paradoxical temerity, shuts up her chance of rapid discovery, for the present at least, in a fairly narrow circle It taints too her extensions of physical truth into the psychological field with a pursuing sense of inadequacy And this inadequacy in extended application is very evident in her theories of heredity and evolution when she forces them beyond their safe ground of physical truth and labours to illumine by them the subtle, complex, elusive phenomena of our psychological being.

There are still, I dare say, persons here and there who cherish a secret or an open unfaith in the theory of a physical evolution and believe that it will one day pass into the limbo of dead generalisations like the Ptolemaic theory in astronomy or like the theory of humours in medicine; but this is a rare and excessive scepticism Yet it may not be without use or aptitude for our purpose to note that contrary to current popular notions the scientific account of this generalisation, like that of a good number of others, is not yet conclusively proved, even though now taken for granted But still there is on the whole a mass of facts and indications in its favour so considerable as to look overwhelming, so that we cannot resist the conclusion that in

this way or some such way the whole thing came about and we find it difficult to conceive any more convincing explanation of the indubitable ascending and branching scale of genus and species which meets even our casual scrutiny of living existence One thing at least seems now intellectually certain, we can no longer believe that these suns and systems were hurled full-shaped and eternally arranged into boundless space and all these numberless species of being planted on earth ready-made and nicely tailored in seven days or any number of days in a sudden outburst of caprice or Dionysiac excitement or crowded activity of mechanical conception by the fiat of a timeless Creator The successive development which was summarily proposed by the ancient Hindu thinkers, the lower forms of being first, man afterwards as the crown of the Spirit's development of life on earth, has been confirmed by the patient and detailed scrutiny of physical science, —an aeonic development, though the farther Hindu conception of a constant repetition of the principle in cycles is necessarily incapable of physical evidence.

One thing more seems now equally certain that not only the seed of all life was one, —again the great intuition of the Upanishads foreruns the conclusions of the physical enquiry, one seed which the universal self-existence by process of force         has disposed in many ways, ekam bījam bahudhā śakti-yogāt, —but even the principle of development is one and the structural ground-plan too as it develops step by step, in spite of all departures to this side or that in the workings of the creative Force or the creative Idea Nature seems to start with an extraordinary poverty of original broad variative conceptions and to proceed to an extraordinary richness of her minuter consequential variations, which amounts to a forging of constant subtle differentiations of species and in the individual a startling insistence on result of uniqueness It almost looks as if in the process of her physical harmonies there was meant to be some formal effect or symbolic reproduction of the truth that all things are originally one being, but a one who insists on his own infinite diversity, and even a suggestion that there is in this eternal unity an eternal pluralism, the Infinite Being self-repeated in an infinite

multiplicity of beings each unique and yet each the One To a mind on the look-out for the metaphysical suggestions we can draw from the apparent facts of being, that might not seem altogether an imagination.

In any case we have this now patent order in the profuse complexities of the natural harmony of living things, —one plasmic seed, one developing ground-plan, an opulent number of varieties whose logical process would be by an ascending order which passes up through fine but still very distinct gradations from the crude to the complex, from the less organised to the more organised, from the inferior to the superior type The first question that should strike the mind at once, when this tree of life has been seen, is whether this logical order was indeed the actual order in the history of the universe, and then, a second, naturally arising from that problem, whether, if so, each new form developed by variation from its natural predecessor or came in by some unknown process, a fresh, independent and in a way sudden creation In the first case, we have the scientific order of physical evolution, —in the other one knows not well what, perhaps an unseen Demiurge who developed the whole thing in the earlier period of the earth evolution and has now wholly or almost entirely stopped the business so that we have no new physical development of that kind, but only, it may be, an evolution of capacity in types already created Science stands out for a quite natural and mechanical, a quite unbroken physical evolution with many divergent lines indeed of developing variation, but in the line no gap or interstice It is true that there are not one but a host of missing links, which even the richest remains of the past cannot fill in, and we are not in a position to deny with an absolute dogmatism the possibility of an advance per saltum, by a rapid overleaping, perhaps even by a crowded psychical or bio-psychic preparation whose result sprang out in the appearance of a new type with a certain gulf between itself and the preceding forms of life With regard to man especially there is still an enormous uncertainty as to how he, so like yet so different from the other sons of Nature, came into existence Still the gaps can be explained away, there is a great mass of

telling facts in favour of the less physically anarchic view, and it seems to have on its side the right of greatest probability in a material universe where the most perfectly physical principle of proceeding would seem to be the just basic law.

But even if we admit the most scrupulous and rigorous continuity of successive determination, the question arises whether the process of evolution has been indeed so exclusively physical and biological as at first sight it looks If it is, we must admit not only a rigorous principle of class heredity, but a law of hereditary progressive variation and a purely physical cause of all mental and spiritual phenomena Heredity by itself means simply the constant transmission of physical form and biological characteristics from a previous life to its posterity There is very evidently such a general force of hereditary transmission within the genus or species itself, as the tree so the seed, as the seed so the tree, so that a lion generates a lion and not a cat or a rhinoceros, a man a human being and not an ourang-outang, —though one reads now of a curious and startling speculation, turning the old theory topsy-turvy, that certain ape kinds may be, not ancestors, but degenerate descendants of man! But farther, if a physical evolution is the whole fact, there must be a capacity for the hereditary transmission of variations by which new species are or have been created, —not merely in the process of a mixture or crossing, but by an internal development which is stored up and handed down in the seed That too may very well be admitted, even though its real process and rationale are not yet understood, since the transmission of family and individual characteristics is a well-observed phenomenon But then the things transmitted are not only physical and biological, but psychological or at least bio-psychic characters, repetitions of customary nervous experience and mental tendency, powers We have to suppose that the physical seed transmits these things We are called upon to admit that the human seed for instance, which does not contain a developed human consciousness, yet carries with it the powers of such a consciousness so that they reproduce themselves automatically in the thinking and organised mentality of the offspring This, even if we have to accept

it, is an inexplicable paradox unless we suppose either that there is something more behind, a psychical power behind the veil of material process, or else that mind is only a process of life and life only a process of matter Therefore finally we have to suppose the physical theory capable of explaining by purely material causes and a material constitution the mystery of the emergence of life in matter and the equal mystery of the emergence of mind in life It is here that difficulties begin to crowd in which convict it, so far at least, of a hopeless inadequacy, and the nature of that inadequacy, its crux, its stumbling-point leave room for just that something behind, something psychical, a hidden soul process and for a more complex and less materialistic account of the truth of evolution.

The materialistic assumption —it is no more than a hypothetical assumption, for it has never been proved —is that development of non-living matter results under certain unknown conditions in a phenomenon of unconscious life which is in its real nature only an action and reaction of material energy, and the development of that again under certain unknown conditions in a phenomenon of conscious mind which is again in its real nature only an action and reaction of material energy The thing is not proved, but that, it is argued, does not matter; it only means that we do not yet know enough; but one day we shall know, —the necessary physiological reaction called by us an intuition or train of reasoning crowned by discovery having, I suppose, taken place in a properly constituted nervous body and the more richly convoluted brain of a Galileo of biology, —and then this great and simple truth will be proved, like many other things once scoffed at by the shallow common sense of humanity But the difficulty is that it seems incapable of proof Even with regard to life, which is by a great deal the lesser difficulty, the discovery of certain chemical or other physical and mechanical conditions under which life can be stimulated to appear, will prove no more than that these are the favourable or necessary conditions for the manifestation of life in body, —such conditions there must be in the nature of things, —but not that life is not another new and higher power of the force of universal being The connection of

life responses with physical conditions and stimuli proves very clearly that life and matter are connected and that, as indeed they must do to coexist, the two kinds of energy act on each other, —a very ancient knowledge; but it does not get rid of the fact that the physical response is accompanied by an element which seems to be of the nature of a nervous excitement and an incipient or suppressed consciousness and is not the same thing as the companion physical reaction.

When we come to mind, we see —how could it be otherwise in an embodied mind? —a response, interaction, connection, a correspondence if you will; but no amount of correspondence can show how a physical response can be converted into or amount to or by itself constitute in result a conscious operation, a perception, emotion, thought-concept, or prove that love is a chemical product or that Plato's theory of ideas or Homer's Iliad or the cosmic consciousness of the Yogin was only a combination of physiological reactions or a complex of the changes of grey brain matter or a flaming marvel of electrical discharges It is not only that common sense and imagination boggle at these theories, —that objection may be disregarded, —not only that perception, reason and intuition have to be thrust aside in favour of a forced and too extended inference, but that there is a gulf of difference here between the thing to be explained and the thing by which it is sought to explain it which cannot be filled up, however much we may admit nervous connections and psycho-physical bridges And if the physical scientist points to a number of indicative facts and hopes one day to triumph over these formidable difficulties, there is growing up on the other side an incipient mass of psychical phenomena which are likely to drown his theory in fathomless waters The insuperability of these always evident objections is beginning to be more widely recognised, but since the past still holds considerable sway, it is necessary to insist on them so that we may have the clear right to go on to more liberal hypotheses which do not try prematurely to reduce to a mechanical simplicity the problem of our being.

One of these is the ancient view that not only incidence of body and life on mind and soul, but incidence of mind and  

Page – 283

soul on body and life have to be considered Here too there is the evolutionary idea, but physical and life evolution, even the growth of mind, are held to be only incidental to a soul evolution of which Time is the course and the earth among many other worlds the theatre In the old Indian version of this theory evolution, heredity and rebirth are three companion processes of the universal unfolding, evolution the processional aim, rebirth the main method, heredity one of the physical conditions That is a theory which provides at least the framework for a harmonious explanation of all the complex elements of the problem The scientific idea starts from physical being and makes the psychical a result and circumstance of body; this other evolutionary idea starts from soul and sees in the physical being an instrumentation for the awakening to itself of a spirit absorbed in the universe of Matter.
