But before entering into an examination of the functions and vagaries of this force, of which everything, from a cataclysm to a blade of grass, is a derivative, it is well to inquire what its exact rank is. It has been already said that in man it was the foundation of being, but from very early times,—as a matter of fact, since the days in which Anaxagoras lived and taught,—the intellect has held, among all man's other attributes, a sceptre hitherto uncontested. If Schopenhauer, however, is to be believed, the supremacy hitherto accorded to it has been the result of error. The throne, by grace divine, belongs to Will. The intellect is but the prime minister, the instrument of a higher force, as the hammer is that of the smith.

If the matter be examined however casually, it will become at once clear that what we are most conscious of in effort, hope, desire, fear, love, hatred, and determination, are the workings and manifestations of Will. If the animal is considered, it will be seen that in the descending scale intelligence becomes more and more imperfect, while Will remains entirely unaffected. The smallest insect wants what it wants as much as man. The intellect, moreover, becomes wearied, while Will is indefatigable. Indeed, when it is remembered that such men as Swift, Kant, Scott, Southey, Rousseau, and Emerson have fallen into a state of intellectual debility, it is well-nigh impossible to deny that the mind is but a function of the body, which, in turn, is a function of the Will. But that which probably shows the secondary and dependent nature of the intelligence more clearly is its peculiar characteristic of intermittence and periodicity. In deep sleep, the brain rests, while the other organs continue their work. In brief, then, Intellect is the light and Will the warmth. "In me," Schopenhauer says, "the indestructible is not the soul, but rather, to employ a chemical term, the basis of the soul, which is Will."

Will, moreover, is not only the foundation of being, but, as has been noted, it is the universal essence. Schopenhauer points out the ascension of sap in plants, which is no easy problem in hydraulics, and the insect's marvelous anticipations of the future, and asks what is it all but Will? The vital force itself, he says, is Will,—Will to live,—while the organism of the body is but Will manifested, Will become visible.

As Schopenhauer describes it, Will is also identical, immutable, and free. Its identity is shown in inorganic life in the irresistible tendency of water to precipitate itself into cavities, the perseverance with which the loadstone turns to the north, the longing that iron has to attach itself to it, the violence with which contrary currents of electricity try to unite the choice of fluids, and in the manner in which they join and separate. In organic life, it is shown by the fact that every vegetable has a peculiar characteristic: one wants a damp soil, another needs a dry one; one grows only on high ground, another in the valley; one turns to the light, another to the water; while the climbing plant seeks a support. In the animal kingdom there exists another form, which is noticeable in the partly voluntary, partly involuntary movements of the lowest type. When, however, in the evolution of Will the insect or the animal seeks and chooses its food, then intelligence begins and volition passes from darkness into light.

Will, too, is immutable. It never varies; it is the same in man as in the caterpillar, for, as has been said, what an insect wants it wants as decidedly as does a man; the only difference is in the object of desire. The immutability of Will, moreover, is the base of its indestructibility; it never perishes, and for that matter what does? In the world of phenomena all things, it is true, seem to have a birth and a death, but that is but an illusion, which the philosopher does not share. Our true being, and the veritable essence of all things, dwell, Schopenhauer says, in a region where time is not, and where the concepts of birth and death are without significance. The fear of death, he adds parenthetically, is a purely independent sentiment, and one which has its origin in the Will to live. Briefly, it is an illusion which man brings with him when he is born, and which guides him through life; for notice that were this fear of death perfectly reasonable, man would be as uneasy about the chaos which preceded his existence as about that which is to follow it.

Let the individual die, however; the species is indestructible, for death is to the species as sleep is to the individual. The species contains the indestructible, the immutable Will of which the individual is a manifestation. It contains all that is, all that was, and all that will be.

"When we think of the future and of the coming generations, the millions of human beings who will differ from us in habits and customs, and we try in imagination to fancy them with us, we wonder from where they will spring, where they are now? Where is this fecund chaos, rich in worlds, that hides the generations that are to be? And where can it be save there, where every reality has been and will be,—here, in the present, and what it contains. And you, foolish questioner, who do not recognize your own essence, you are like the leaf on the tree which, withering in autumn, and feeling it is about to fall, laments at death, inconsolable at the knowledge of the fresh verdure which in spring will cover the tree once more. The leaf cries, 'I am no more.' Foolish leaf, where do you go? Whence do the fresh leaves come? Where is this chaos whose gulf you fear? See, your own self is in that force, interior and hidden, acting on the tree which, through all generations of leaves, knows neither birth nor death. And now tell me," Schopenhauer concludes, as though he were about to pronounce a benediction, "tell me, is man unlike the leaf?"

This doctrine, which teaches that through all there is one invariable, identical, and equal force, is the great problem whose solution was sought by Kant, and which he gave up in despair; it is the discovery which makes of Schopenhauer one of the foremost thinkers of the century, and one, it may be added without any unguarded enthusiasm, which will suffice to carry his name into other ages, somewhat in the same manner as the name of Columbus has descended to us.

"If we were to consider," he said, "the nature of this force which admittedly moves the world, but whose psychological examination is so little advanced that the most certain analytical results seem not unlike a paradox, we should be astonished at this fundamental verity which I have been the first to bring to light, and to which I have given its true name,—Will. For what is the world but an enormous Will constantly irrupting into life. Gravitation, electricity, heat, every form of activity, from the fall of an apple to the foundation of a republic, is but the expression of Will, and nothing more."

This doctrine of volition coincides, it may be noted, very perfectly with that of evolution, and it was not difficult for Schopenhauer to show that the more recent results of science were a confirmation of his philosophy. In the "Parerga," which he wrote thirty years after the publication of his chief work, he says that during the early stages of the globe's formation, before the age of granite, the objectivity of the Will-to-live was limited to the most inferior forms; also that the forces were at that time engaged in a combat whose theatre was not alone the surface of the globe, but its entire mass, a combat too colossal for the imagination to grasp. When this Titan conflict of chemical forces had ended, and the granite, like a tombstone, covered the combatants, the Will-to-live, by a striking contrast, irrupted in the peaceful world of plant and forest. This vegetable world decarbonized the air, and prepared it for animal life. The objectivity of Will then realized a new form,—the animal kingdom. Fish and crustaceans filled the sea, gigantic reptiles covered the earth, and gradually through innumerable forms, each more perfect than the last, the Will-to-live ascended finally to man. This stage attained is, in his opinion, destined to be the last, for with it is come the possibility of the denial of the Will, through which the divine comedy will end.
