On the other hand, as has been said, the mechanical tendencies of insects reflect much light upon the working of the unconscious will in the inner functions of the organism and in its construction. For without any difficulty we can see in the ant-hill or the beehive the picture of an organism explained and brought to the light of knowledge. In this sense Burdach says (Physiologie, vol. ii. p. 22): “The formation and depositing of the eggs is the part of the queen-bee, and the care for the cultivation of them falls to the workers; thus in the former the ovary, and in the latter the uterus, is individualised.” In the insect society, as in the animal organism, the vita propria of each part is subordinated to the life of the whole, and the care for the whole precedes that for particular existence; indeed the latter is only conditionally willed, the former unconditionally; therefore the individuals are even sacrificed occasionally for the whole, as we allow a limb to be taken off in order to save the whole body. Thus, for example, if the path is closed by water against the march of the ants, those in front boldly throw themselves in until their corpses are heaped up into a dam for those that follow. When the drones have become useless they are stung to death. Two queens in the hive are surrounded, and must fight with each other till one of them loses its life. The ant-mother bites its own wings off after it has been impregnated, for they would only be a hindrance [pg 101] to it in the work that is before it of tending the new family it is about to found under the earth (Kirby and Spence, vol. i.) As the liver will do nothing more than secrete gall for the service of the digestion, nay, will only itself exist for this end—and so with every other part—the working bees also will do nothing more than collect honey, secrete wax, and make cells for the brood of the queen; the drones nothing more than impregnate; the queen nothing but deposit eggs; thus all the parts work only for the maintenance of the whole which alone is the unconditional end, just like the parts of the organism. The difference is merely that in the organism the will acts perfectly blindly in its primary condition; in the insect society, on the other hand, the thing goes on already in the light of knowledge, to which, however, a decided co-operation and individual choice is only left in the accidents of detail, where it gives assistance and adopts what has to be carried out to the circumstances. But the insects will the end as a whole without knowing it; just like organised nature working according to final causes; even the choice of the means is not as a whole left to their knowledge, but only the more detailed disposition of them. Just on this account, however, their action is by no means automatic, which becomes most distinctly visible if one opposes obstacles to their action. For example, the caterpillar spins itself in leaves without knowing the end; but if we destroy the web it skilfully repairs it. Bees adapt their hive at the first to the existing circumstances, and subsequent misfortunes, such as intentional destruction, they meet in the way most suitable to the special case (Kirby and Spence, Introduc. to Entomol.; Huber, Des abeilles). Such things excite our astonishment, because the apprehension of the circumstances and the adaptation to these is clearly a matter of knowledge; while we believe them capable once for all of the most ingenious preparation for the coming race and the distant future, well knowing that in this they are not guided by knowledge, for a forethought of [pg 102] that kind proceeding from knowledge demands an activity of the brain rising to the level of reason. On the other hand, the intellect even of the lower animals is sufficient for the modifying and arranging of the particular case according to the existing or appearing circumstances; because, guided by instinct, it has only to fill up the gaps which this leaves. Thus we see ants carry off their larvæ whenever the place is too damp, and bring them back again when it becomes dry. They do not know the aim of this, thus are not guided in it by knowledge; but the choice of the time at which the place is no longer suitable for the larvæ, and also of the place to which they now bring them, is left to their knowledge. I wish here also to mention a fact which some one related to me verbally from his own experience, though I have since found that Burdach quotes it from Gleditsch. The latter, in order to test the burying-beetle (Necrophorus vespillo), had tied a dead frog lying upon the ground to a string, the upper end of which was fastened to a stick stuck obliquely in the ground. Now after several burying-beetles had, according to their custom, undermined the frog, it could not, as they expected, sink into the ground; after much perplexed running hither and thither they undermined the stick also. To this assistance rendered to instinct, and that repairing of the works of mechanical tendency, we find in the organism the healing power of nature analogous, which not only heals wounds, replacing even bone and nerve substance, but, if through the injury of a vein or nerve branch a connection is interrupted, opens a new connection by means of enlargement of other veins or nerves, nay, perhaps even by producing new branches; which further makes some other part or function take the place of a diseased part or function; in the case of the loss of an eye sharpens the other, or in the case of the loss of one of the senses sharpens all the rest; which even sometimes closes an intestinal wound, in itself fatal, by the adhesion of the mesentery or the peritoneum; in short, seeks to meet every [pg 103] injury and every disturbance in the most ingenious manner. If, on the other hand, the injury is quite incurable, it hastens to expedite death, and indeed the more so the higher is the species of the organism, thus the greater its sensibility. Even this has its analogue in the instinct of insects. The wasps, for instance, who through the whole summer have with great care and labour fed their larvæ on the produce of their plundering, but now, in October, see the last generation of them facing starvation, sting them to death (Kirby and Spence, vol. i. p. 374). Nay, still more curious and special analogies may be found; for example, this: if the female humble-bee (Apis terrestris, bombylius) lays eggs, the working humble-bees are seized with a desire to devour them, which lasts from six to eight hours and is satisfied unless the mother keeps them off and carefully guards the eggs. But after this time the working humble-bees show absolutely no inclination to eat the eggs even when offered to them; on the contrary, they now become the zealous tenders and nourishers of the larvæ now being hatched out. This may without violence be taken as an analogue of children's complaints, especially teething, in which it is just the future nourishers of the organism making an attack upon it which so often costs it its life. The consideration of all these analogies between organised life and the instinct, together with the mechanical tendencies of the lower animals, serves ever more to confirm the conviction that the will is the basis of the one as of the other, for it shows here also the subordinate rôle of knowledge in the action of the will, sometimes more, sometimes less, confined, and sometimes wanting altogether.
But in yet another respect instincts and the animal organisation reciprocally illustrate each other: through the anticipation of the future which appears in both. By means of instincts and mechanical tendencies animals care for the satisfaction of wants which they do not yet feel, nay, not only for their own wants, but even for those [pg 104] of the future brood. Thus they work for an end which is as yet unknown to them. This goes so far, as I have illustrated by the example of the Bombex in “The Will in Nature” (second edit. p. 45, third edit. p. 47), that they pursue and kill in advance the enemies of their future eggs. In the same way we see the future wants of an animal, its prospective ends, anticipated in its whole corporisation by the organised implements for their attainment and satisfaction; from which, then, proceeds that perfect adaptation of the structure of every animal to its manner of life, that equipment of it with the needful weapons to attack its prey and to ward off its enemies, and that calculation of its whole form with reference to the element and the surroundings in which it has to appear as a pursuer, which I have fully described in my work on the will in nature under the rubric “Comparative Anatomy.” All these anticipations, both in the instinct and in the organisation of animals, we might bring under the conception of a knowledge a priori, if knowledge lay at their foundation at all. But this is, as we have shown, not the case. Their source lies deeper than the sphere of knowledge, in the will as the thing in itself, which as such remains free even from the forms of knowledge; therefore with reference to it time has no significance, consequently the future lies as near it as the present.
Chapter XXVIII.[6] Characterisation Of The Will To Live.
Our second book closed with the question as to the goal and aim of that will which had shown itself to be the inner nature of all things in the world. The following remarks may serve to supplement the answer to this question given there in general terms, for they lay down the character of the will as a whole.
Such a characterisation is possible because we have recognised as the inner nature of the world something thoroughly real and empirically given. On the other hand, the very name “world-soul,” by which many have denoted that inner being, gives instead of this a mere ens rationis; for “soul” signifies an individual unity of consciousness which clearly does not belong to that nature, and in general, since the conception “soul” supposes knowing and willing in inseparable connection and yet independent of the animal organism, it is not to be justified, and therefore not to be used. The word should never be applied except in a metaphorical sense, for it is much more insidious than ψυχη or anima, which signify breath.
Much more unsuitable, however, is the way in which so-called pantheists express themselves, whose whole philosophy consists chiefly in this, that they call the inner nature of the world, which is unknown to them, “God;” by which indeed they imagine they have achieved much. According to this, then, the world would be a theophany. But let one only look at it: this world of constantly needy [pg 106] creatures, who continue for a time only by devouring one another, fulfil their existence in anxiety and want, and often suffer terrible miseries, till at last they fall into the arms of death; whoever distinctly looks upon this will allow that Aristotle was right in saying: “ἡ φυσις δαιομονια, αλλ᾽ ου θεια εστι” (Natura dæmonia est, non divina), De divinat., c. 2, p. 463; nay, he will be obliged to confess that a God who could think of changing Himself into such a world as this must certainly have been tormented by the devil. I know well that the pretended philosophers of this century follow Spinoza in this, and think themselves thereby justified. But Spinoza had special reasons for thus naming his one substance, in order, namely, to preserve at least the word, although not the thing. The stake of Giordano Bruno and of Vanini was still fresh in the memory; they also had been sacrificed to that God for whose honour incomparably more human sacrifices have bled than on the altars of all heathen gods of both hemispheres together. If, then, Spinoza calls the world God, it is exactly the same thing as when Rousseau in the “Contrat social,” constantly and throughout denotes the people by the word le souverain; we might also compare it with this, that once a prince who intended to abolish the nobility in his land, in order to rob no one of his own, hit upon the idea of ennobling all his subjects. Those philosophers of our day have certainly one other ground for the nomenclature we are speaking of, but it is no more substantial. In their philosophising they all start, not from the world or our consciousness of it, but from God, as something given and known; He is not their quæsitum, but their datum. If they were boys I would then explain to them that this is a petitio principii, but they know this as well as I do. But since Kant has shown that the path of the earlier dogmatism, which proceeded honestly, the path from the world to a God, does not lead there, these gentlemen now imagine they have found a fine way of escape and made it cunningly. Will [pg 107] the reader of a later age pardon me for detaining him with persons of whom he has never heard.
Every glance at the world, to explain which is the task of the philosopher, confirms and proves that will to live, far from being an arbitrary hypostasis or an empty word, is the only true expression of its inmost nature. Everything presses and strives towards existence, if possible organised existence, i.e., life, and after that to the highest possible grade of it. In animal nature it then becomes apparent that will to live is the keynote of its being, its one unchangeable and unconditioned quality. Let any one consider this universal desire for life, let him see the infinite willingness, facility, and exuberance with which the will to live presses impetuously into existence under a million forms everywhere and at every moment, by means of fructification and of germs, nay, when these are wanting, by means of generatio æquivoca, seizing every opportunity, eagerly grasping for itself every material capable of life: and then again let him cast a glance at its fearful alarm and wild rebellion when in any particular phenomenon it must pass out of existence; especially when this takes place with distinct consciousness. Then it is precisely the same as if in this single phenomenon the whole world would be annihilated for ever, and the whole being of this threatened living thing is at once transformed into the most desperate struggle against death and resistance to it. Look, for example, at the incredible anxiety of a man in danger of his life, the rapid and serious participation in this of every witness of it, and the boundless rejoicing at his deliverance. Look at the rigid terror with which a sentence of death is heard, the profound awe with which we regard the preparations for carrying it out, and the heartrending compassion which seizes us at the execution itself. We would then suppose there was something quite different in question than a few less years of an empty, sad existence, embittered by troubles of every kind, and always uncertain: [pg 108] we would rather be amazed that it was a matter of any consequence whether one attained a few years earlier to the place where after an ephemeral existence he has billions of years to be. In such phenomena, then, it becomes visible that I am right in declaring that the will to live is that which cannot be further explained, but lies at the foundation of all explanations, and that this, far from being an empty word, like the absolute, the infinite, the idea, and similar expressions, is the most real thing we know, nay, the kernel of reality itself.
But if now, abstracting for a while from this interpretation drawn from our inner being, we place ourselves as strangers over against nature, in order to comprehend it objectively, we find that from the grade of organised life upwards it has only one intention—that of the maintenance of the species. To this end it works, through the immense superfluity of germs, through the urgent vehemence of the sexual instinct, through its willingness to adapt itself to all circumstances and opportunities, even to the production of bastards, and through the instinctive maternal affection, the strength of which is so great that in many kinds of animals it even outweighs self-love, so that the mother sacrifices her life in order to preserve that of the young. The individual, on the contrary, has for nature only an indirect value, only so far as it is the means of maintaining the species. Apart from this its existence is to nature a matter of indifference; indeed nature even leads it to destruction as soon as it has ceased to be useful for this end. Why the individual exists would thus be clear; but why does the species itself exist? That is a question which nature when considered merely objectively cannot answer. For in vain do we seek by contemplating her for an end of this restless striving, this ceaseless pressing into existence, this anxious care for the maintenance of the species. The strength and time of the individuals are consumed in the effort to procure sustenance for themselves and their young, and are only just sufficient, sometimes even [pg 109] not sufficient, for this. Even if here and there a surplus of strength, and therefore of comfort—in the case of the one rational species also of knowledge—remains, this is much too insignificant to pass for the end of that whole process of nature. The whole thing, when regarded thus purely objectively, and indeed as extraneous to us, looks as if nature was only concerned that of all her (Platonic) Ideas, i.e., permanent forms, none should be lost. Accordingly, as if she had so thoroughly satisfied herself with the fortunate discovery and combination of these Ideas (for which the three preceding occasions on which she stocked the earth's surface with animals were only the preparation), that now her only fear is lest any one of these beautiful fancies should be lost, i.e., lest any one of these forms should disappear from time and the causal series. For the individuals are fleeting as the water in the brook; the Ideas, on the contrary, are permanent, like its eddies: but the exhaustion of the water would also do away with the eddies. We would have to stop at this unintelligible view if nature were known to us only from without, thus were given us merely objectively, and we accepted it as it is comprehended by knowledge, and also as sprung from knowledge, i.e., in the sphere of the idea, and were therefore obliged to confine ourselves to this province in solving it. But the case is otherwise, and a glance at any rate is afforded us into the interior of nature; inasmuch as this is nothing else than our own inner being, which is precisely where nature, arrived at the highest grade to which its striving could work itself up, is now by the light of knowledge found directly in self-consciousness. Here the will shows itself to us as something toto genere different from the idea, in which nature appears unfolded in all her (Platonic) Ideas; and it now gives us, at one stroke, the explanation which could never be found upon the objective path of the idea. Thus the subjective here gives the key for the exposition of the objective. In order to recognise, as something original and unconditioned, that exceedingly strong [pg 110] tendency of all animals and men to retain life and carry it on as long as possible—a tendency which was set forth above as characteristic of the subjective, or of the will—it is necessary to make clear to ourselves that this is by no means the result of any objective knowledge of the worth of life, but is independent of all knowledge; or, in other words, that those beings exhibit themselves, not as drawn from in front, but as impelled from behind.
