His earliest book was a vision of what the inner life of plants may be like. He called it 'Nanna.' In the development of animals the nervous system is the central fact. Plants develop centrifugally, spread their organs abroad. For that reason people suppose that they can have no consciousness, for they lack the unity which the central nervous system provides. But the plant's consciousness may be of another type, being connected with other structures. Violins and pianos give out sounds because they have strings. Does it follow that nothing but strings can give out sound? How then about flutes and organ-pipes? Of course their sounds are of a different quality, and so may the consciousness of plants be of a quality correlated exclusively with the kind of organization that | they possess. Nutrition, respiration, propagation take place in them without nerves. In us these functions are conscious only in unusual states, normally their consciousness is eclipsed by that which goes with the brain. No such eclipse occurs in plants, and their lower consciousness may therefore be all the more lively. With nothing to do but to drink the light and air with their leaves, to let their cells proliferate, to feel their rootlets draw the sap, is it conceivable that they should not consciously suffer if water, light, and air are suddenly withdrawn? or that when the flowering and fertilization which are the culmination of their life take place, they should not feel their own existence more intensely and enjoy something like what we call pleasure in ourselves? Does the water-lily, rocking in her triple bath of water, air, and light, relish in no wise her own beauty? When the plant in our room turns to the light, closes her blossoms in the dark, responds to our watering or pruning by increase of size or change of shape and bloom, who has the right to say she does not feel, or that she plays a purely passive part? Truly plants can foresee nothing, neither the scythe of the mower, nor the hand extended to pluck their flowers. They can neither run away nor cry out. But this only proves how different their modes of feeling life must be from those of animals that live by eyes and ears and locomotive organs, it does not prove that they have no mode of feeling life at all.
How scanty and scattered would sensation be on our globe, if the feeling-life of plants were blotted from existence. Solitary would consciousness move through the woods in the shape of some deer or other quadruped, or fly about the flowers in that of some insect, but can we really suppose that the Nature through which God's breath blows is such a barren wilderness as this?
I have probably by this time said enough to acquaint those of you who have never seen these metaphysical writings of Fechner with their more general characteristics, and I hope that some of you may now feel like reading them yourselves.[3] The special thought of Fechner's with which in these lectures I have most practical concern, is his belief that the more inclusive forms of consciousness are in part constituted by the more limited forms. Not that they are the mere sum of the more limited forms. As our mind is not the bare sum of our sights plus our sounds plus our pains, but in adding these terms together also finds relations among them and weaves them into schemes and forms and objects of which no one sense in its separate estate knows anything, so the earth-soul traces relations between the contents of my mind and the contents of yours of which neither of our separate minds is conscious. It has schemes, forms, and objects proportionate to its wider field, which our mental fields are far too narrow to cognize. By ourselves we are simply out of relation with each other, for it we are both of us there, and different from each other, which is a positive relation. What we are without knowing, it knows that we are. We are closed against its world, but that world is not closed against us. It is as if the total universe of inner life had a sort of grain or direction, a sort of valvular structure, permitting knowledge to flow in one way only, so that the wider might always have the narrower under observation, but never the narrower the wider.
Fechner's great analogy here is the relation of the senses to our individual minds. When our eyes are open their sensations enter into our general mental life, which grows incessantly by the addition of what they see. Close the eyes, however, and the visual additions stop, nothing but thoughts and memories of the past visual experiences remain—in combination of course with the enormous stock of other thoughts and memories, and with the data coming in from the senses not yet closed. Our eye-sensations of themselves know nothing of this enormous life into which they fall. Fechner thinks, as any common man would think, that they are taken into it directly when they occur, and form part of it just as they are. They don't stay outside and get represented inside by their copies. It is only the memories and concepts of them that are copies; the sensible perceptions themselves are taken in or walled out in their own proper persons according as the eyes are open or shut.
Fechner likens our individual persons on the earth unto so many sense-organs of the earth's soul. We add to its perceptive life so long as our own life lasts. It absorbs our perceptions, just as they occur, into its larger sphere of knowledge, and combines them with the other data there. When one of us dies, it is as if an eye of the world were closed, for all perceptive contributions from that particular quarter cease. But the memories and conceptual relations that have spun themselves round the perceptions of that person remain in the larger earth-life as distinct as ever, and form new relations and grow and develop throughout all the future, in the same way in which our own distinct objects of thought, once stored in memory, form new relations and develop throughout our whole finite life. This is Fechner's theory of immortality, first published in the little 'Büchlein des lebens nach dem tode,' in 1836, and re-edited in greatly improved shape in the last volume of his 'Zend-avesta.'
We rise upon the earth as wavelets rise upon the ocean. We grow out of her soil as leaves grow from a tree. The wavelets catch the sunbeams separately, the leaves stir when the branches do not move. They realize their own events apart, just as in our own consciousness, when anything becomes emphatic, the background fades from observation. Yet the event works back upon the background, as the wavelet works upon the waves, or as the leaf's movements work upon the sap inside the branch. The whole sea and the whole tree are registers of what has happened, and are different for the wave's and the leaf's action having occurred. A grafted twig may modify its stock to the roots:—so our outlived private experiences, impressed on the whole earth-mind as memories, lead the immortal life of ideas there, and become parts of the great system, fully distinguished from one another, just as we ourselves when alive were distinct, realizing themselves no longer isolatedly, but along with one another as so many partial systems, entering thus into new combinations, being affected by the perceptive experiences of those living then, and affecting the living in their turn—altho they are so seldom recognized by living men to do so.
If you imagine that this entrance after the death of the body into a common life of higher type means a merging and loss of our distinct personality, Fechner asks you whether a visual sensation of our own exists in any sense less for itself or less distinctly, when it enters into our higher relational consciousness and is there distinguished and defined.
—But here I must stop my reporting and send you to his volumes. Thus is the universe alive, according to this philosopher! I think you will admit that he makes it more thickly alive than do the other philosophers who, following rationalistic methods solely, gain the same results, but only in the thinnest outlines. Both Fechner and Professor Royce, for example, believe ultimately in one all-inclusive mind. Both believe that we, just as we stand here, are constituent parts of that mind. No other content has it than us, with all the other creatures like or unlike us, and the relations which it finds between us. Our eaches, collected into one, are substantively identical with its all, tho the all is perfect while no each is perfect, so that we have to admit that new qualities as well as unperceived relations accrue from the collective form. It is thus superior to the distributive form. But having reached this result, Royce (tho his treatment of the subject on its moral side seems to me infinitely richer and thicker than that of any other contemporary idealistic philosopher) leaves us very much to our own devices. Fechner, on the contrary, tries to trace the superiorities due to the more collective form in as much detail as he can. He marks the various intermediary stages and halting places of collectivity,—as we are to our separate senses, so is the earth to us, so is the solar system to the earth, etc.,—and if, in order to escape an infinitely long summation, he posits a complete God as the all-container and leaves him about as indefinite in feature as the idealists leave their absolute, he yet provides us with a very definite gate of approach to him in the shape of the earth-soul, through which in the nature of things we must first make connexion with all the more enveloping superhuman realms, and with which our more immediate religious commerce at any rate has to be carried on.
Ordinary monistic idealism leaves everything intermediary out. It recognizes only the extremes, as if, after the first rude face of the phenomenal world in all its particularity, nothing but the supreme in all its perfection could be found. First, you and I, just as we are in this room; and the moment we get below that surface, the unutterable absolute itself! Doesn't this show a singularly indigent imagination? Isn't this brave universe made on a richer pattern, with room in it for a long hierarchy of beings? Materialistic science makes it infinitely richer in terms, with its molecules, and ether, and electrons, and what not. Absolute idealism, thinking of reality only under intellectual forms, knows not what to do with bodies of any grade, and can make no use of any psychophysical analogy or correspondence. The resultant thinness is startling when compared with the thickness and articulation of such a universe as Fechner paints. May not satisfaction with the rationalistic absolute as the alpha and omega, and treatment of it in all its abstraction as an adequate religious object, argue a certain native poverty of mental demand? Things reveal themselves soonest to those who most passionately want them, for our need sharpens our wit. To a mind content with little, the much in the universe may always remain hid.
To be candid, one of my reasons for saying so much about Fechner has been to make the thinness of our current transcendentalism appear more evident by an effect of contrast. Scholasticism ran thick; Hegel himself ran thick; but english and american transcendentalisms run thin. If philosophy is more a matter of passionate vision than of logic,—and I believe it is, logic only finding reasons for the vision afterwards,—must not such thinness come either from the vision being defective in the disciples, or from their passion, matched with Fechner's or with Hegel's own passion, being as moonlight unto sunlight or as water unto wine?[4]
