us nothing about this force except the conditions under which, and the laws in accordance with which, it manifests itself. Let us now raise the temperature and add pure acid; the whole machine burns; that is to say, once more an entirely different force of nature, chemical energy, asserts at this time and in this place irresistible claims to this particular matter, and reveals itself in it as Idea, as a definite grade of the objectification of will. The calcined metal thus produced now unites with an acid, and a salt is obtained which forms itself into crystals. These are the phenomena of another Idea, which in itself is again quite inexplicable, while the appearance of its phenomena is dependent upon certain conditions which etiology can give us. The crystals dissolve, mix with other materials, and vegetation springs up from them—a new phenomenon of will: and so the same permanent matter may be followed ad infinitum, to observe how now this and now that natural force obtains a right to it and temporarily takes possession of it, in order to appear and reveal its own nature. The condition of this right, the point of time and space at which it becomes valid, is given by causality, but the explanation founded upon this law only extends thus far. The force itself is a manifestation of will, and as such is not subject to the forms of the principle of sufficient reason, that is, it is groundless. It lies outside all time, is omnipresent, and seems as it were to wait constantly till the circumstances occur under which it can appear and take possession of a definite matter, supplanting the forces which have reigned in it till then. All time exists only for the phenomena of such a force, and is without significance for the force itself. Through thousands of years chemical forces slumber in matter till the contact with the reagents sets them free; then they appear; but time exists only for the phenomena, not for the forces themselves. For thousands of years galvanism slumbered in copper and zinc, and they lay quietly beside silver, which must be consumed in flame as soon as all three are brought together under the required conditions. Even in the organic kingdom we see a dry seed preserve the slumbering force through three thousand years, and when at last the favourable circumstances occur, grow up as a plant.35
If by this exposition the difference between a force of nature and all its phenomena has been made quite distinct; if we have seen clearly that the former is the will itself at this particular grade of its objectification, but that multiplicity comes to phenomena only through time and space, and that the law of causality is nothing but the determination of the position of these phenomena in time and space; then we shall recognise the complete truth and the deep meaning of Malebranche's doctrine of occasional causes (causes occasionelles). It is well worth while comparing this doctrine of his, as he explains it in the “Recherches de la Vérite,” both in the 3rd Chapter of the second part of the 6th Book, and in the éclaircissements appended to this chapter, with this exposition of mine, and observing the complete agreement of the two doctrines in the case of such different systems of thought. Indeed I cannot help admiring how Malebranche, though thoroughly involved in the positive dogmas which his age inevitably forced upon him, yet, in such bonds and under such a burden, hit the truth so happily, so correctly, and even knew how to combine it with these dogmas, at all events verbally.
For the power of truth is incredibly great and of unspeakable endurance. We find constant traces of it in all, even the most eccentric and absurd dogmas, of different times and different lands—often indeed in strange company, curiously mixed up with other things, but still recognisable. It is like a plant that germinates under a heap of great stones, but still struggles up to the light, working itself through with many deviations and windings, disfigured, worn out, stunted in its growth—but yet, to the light.
In any case Malebranche is right: every natural cause is only an occasional cause. It only gives opportunity or occasion for the manifestation of the one indivisible will which is the “in-itself” of all things, and whose graduated objectification is the whole visible world. Only the appearance, the becoming visible, in this place, at this time, is brought about by the cause and is so far dependent on it, but not the whole of the phenomenon, nor its inner nature. This is the will itself, to which the principle of sufficient reason has not application, and which is therefore groundless. Nothing in the world has a sufficient cause of its existence generally, but only a cause of existence just here and just now. That a stone exhibits now gravity, now rigidity, now electricity, now chemical qualities, depends upon causes, upon impressions upon it from without, and is to be explained from these. But these qualities themselves, and thus the whole inner nature of the stone which consists in them, and therefore manifests itself in all the ways referred to; thus, in general, that the stone is such as it is, that it exists generally—all this, I say, has no ground, but is the visible appearance of the groundless will. Every cause is thus an occasional cause. We have found it to be so in nature, which is without knowledge, and it is also precisely the same when motives and not causes or stimuli determine the point at which the phenomena are to appear, that is to say, in the actions of animals and human beings. For in both cases it is one and the same will which appears; very different in the grades of its manifestation, multiplied in the phenomena of these grades, and, in respect of these, subordinated to the principle of sufficient reason, but in itself free from all this. Motives do not determine the character of man, but only the phenomena of his character, that is, his actions; the outward fashion of his life, not its inner meaning and content. These proceed from the character which is the immediate manifestation of the will, and is therefore groundless. That one man is bad and another good, does not depend upon motives or outward influences, such as teaching and preaching, and is in this sense quite inexplicable. But whether a bad man shows his badness in petty acts of injustice, cowardly tricks, and low knavery which he practises in the narrow sphere of his circumstances, or whether as a conqueror he oppresses nations, throws a world into lamentation, and sheds the blood of millions; this is the outward form of his manifestation, that which is unessential to it, and depends upon the circumstances in which fate has placed him, upon his surroundings, upon external influences, upon motives; but his decision upon these motives can never be explained from them; it proceeds from the will, of which this man is a manifestation. Of this we shall speak in the Fourth Book. The manner in which the character discloses its qualities is quite analogous to the way in which those of every material body in unconscious nature are disclosed. Water remains water with its intrinsic qualities, whether as a still lake it reflects its banks, or leaps in foam from the cliffs, or, artificially confined, spouts in a long jet into the air. All that depends upon external causes; the one form is as natural to it as the other, but it will always show the same form in the same circumstances; it is equally ready for any, but in every case true to its character, and at all times revealing this alone. So will every human character under all circumstances reveal itself, but the phenomena which proceed from it will always be in accordance with the circumstances.
§ 27. If, from the foregoing consideration of the forces of nature and their phenomena, we have come to see clearly how far an explanation from causes can go, and where it must stop if it is not to degenerate into the vain attempt to reduce the content of all phenomena to their mere form, in which case there would ultimately remain nothing but form, we shall be able to settle in general terms what is to be demanded of etiology as a whole. It must seek out the causes of all phenomena in nature, i.e., the circumstances under which they invariably appear. Then it must refer the multitude of phenomena which have various forms in various circumstances to what is active in every phenomenon, and is presupposed in the cause—original forces of nature. It must correctly distinguish between a difference of the phenomenon which arises from a difference of the force, and one which results merely from a difference of the circumstances under which the force expresses itself; and with equal care it must guard against taking the expressions of one and the same force under different circumstances for the manifestations of different forces, and conversely against taking for manifestations of one and the same force what originally belongs to different forces. Now this is the direct work of the faculty of judgment, and that is why so few men are capable of increasing our insight in physics, while all are able to enlarge experience. Indolence and ignorance make us disposed to appeal too soon to original forces. This is exemplified with an exaggeration that savours of irony in the entities and quidities of the schoolmen. Nothing is further from my desire than to favour their resuscitation. We have just as little right to appeal to the objectification of will, instead of giving a physical explanation, as we have to appeal to the creative power of God. For physics demands causes, and the will is never a cause. Its whole
