Schopenhauer is not one of the philosophers who have founded a school, though he has had many disciples and enthusiastic admirers. The pessimism that was for a time a watchword with certain literary groups has passed as a mode, and his true significance must be sought elsewhere. Of the thinkers who have followed him in his pessimism, two indeed stand out as the architects of distinct systems, Eduard von Hartmann and Philipp MainlÄnder (both already incidentally referred to); but while they are to be classed unquestionably as philosophers, their systems contain an element that their master would have regarded as mythological. Schopenhauer declared as clearly as any of the Greeks that the phenomenal world is without beginning and without end. Kant's positing of an 'antinomy' on this point he regarded as wholly without rational justification. What Kant calls the 'antithesis,' namely, the infinite series, can be logically proved for phenomena. The 'thesis,' which asserts a beginning in time, is defended by mere fallacies. Now Hartmann and MainlÄnder both hold, though in different fashions, that there is a world-process from a beginning to an end, namely, the extinction of consciousness. This is the redemption of the world. Their affinity, therefore, seems to be with the Christian Gnostics rather than with the pure philosophers of the Greek tradition, continued in modern times by Bruno, Spinoza, and Schopenhauer.
Whatever may be thought of the pessimism by which Schopenhauer's mood is distinguished from that of his precursors, few will fail to recognise that special doctrines of his system contain at least a large portion of truth. His theories of Art, of Genius, and of Love are enough to found an enduring reputation for any thinker, even if there were nothing else of value in his writings. But there is much else, both in systematic construction and in the illumination of detail. I have been inclined to put forward first of all the translation into idealistic terms of the universal sentiency held by the Ionian thinkers to be inherent in the primordial elements of nature. While they viewed the world as an objective thing having psychological qualities, Schopenhauer, after the long intermediate process of thought, could treat it as phenomenal object with a psychological or subjective essence. For both doctrines alike, however, mind or soul is immanent. Still, it must be allowed that a difference remains by which Schopenhauer was even more remote than they were from the later Greek idealism. As they were not materialists, so they did not exclude reason from the psychical properties of their substances. Schopenhauer, while he rejected the materialism of their ancient and modern successors alike, took the step of formally derationalising the elements of mind. This, no doubt, is unsustainable ultimately, if reason is ever to emerge from them. Yet the one-sidedness of the position has had a peculiar value in combating an equally one-sided rationalistic idealism. This is recognised by clear-sighted opponents. And Schopenhauer's calling the non-rational or anti-rational element in the world 'will' helps to make plainer the real problem of evil. There is truth in the Hegelian paradox that 'pessimism is an excellent basis for optimism.' An optimist like Plotinus saw that, even if good comes of evil, the case of the optimist must fail unless evil can be shown to be a necessary constituent of the world. The Platonic and Neo-Platonic 'matter,' a principle of diremption or individuation, like time and space for Schopenhauer, was an attempt to solve this problem; but something more positive seemed to be needed as the source of the stronger manifestations of evil. To the strength of these Plato drew attention in a passage (Republic, x. 610[5]) where it is acknowledged that injustice confers a character of vitality and sleeplessness upon its possessor. In the notion of a blind and vehement striving, Schopenhauer supplies something adequate; only, to maintain a rational optimism, it must be regarded as a necessary element in a mixture, not as the spring of the whole.
Much might be said on the teleology by which he tries to educe intelligence from the primordial strife. Against his view, that it is evolved as a mere instrument for preserving races in a struggle, another may be set that is ready to hand in a dialogue of Plutarch.[6] The struggle among animals, it is there incidentally argued, has for its end to sharpen their intelligence. Both these theories are on the surface compatible with evolution. If, leaving aside the problem of mechanism, we try to verify them by the test of results, the latter undoubtedly seems the more plausible. For if the struggle was a means to the improvement of intelligence, nature has succeeded more and more; whereas, if her intention was to preserve races, she has continually failed. This argument is at any rate perfectly valid against Schopenhauer himself; for he holds in common with the optimistic teleologists that 'nature does nothing in vain.'
I will conclude with a few detached criticisms on the ethical doctrine which he regarded as the culmination of his system. The antithesis, it may first be noted, between the temporary release from the vehemence of the will that is gained through art, and the permanent release through asceticism, is not consistently maintained. Schopenhauer admits that the knowledge which for the ascetic is the 'quietive' of the will has to be won anew in a perpetual conflict. 'No one can have enduring rest on earth.' Again, revision of his doctrine concerning the reality of the individual would, I think, necessitate revision also of the position that not only asceticism but 'all true and pure love, nay, even freely rendered justice, proceeds from seeing through the principium individuationis.' If the individual is in some sense ultimately real, then love must be to a certain extent literally altruism. We are brought down to the elementary fact, in terms of the metaphysics of ethics, that the object of love is a real being that is itself and not ourselves, though having some resemblance to us and united in a larger whole. An objection not merely verbal might indeed be taken to Schopenhauer's metaphysics of ethics strictly on his own ground. If it is purely and simply the essence of ourselves that we recognise in everything, does not this reduce all love finally to a well-understood egoism? The genuine fact of sympathy seems to escape his mode of formulation. And, in the end, we shall perhaps not find the ascetic to be the supreme ethical type. Of the self-tormenting kind of asceticism, it is not enough to say with Schopenhauer that, since it is a world-wide phenomenon of human nature, it calls for some account from philosophy. The account may be sufficiently rendered by historical psychology; the result being to class it as an aberration born of the illusions incident to a certain type of mind at a certain stage. Indeed, that seems to be the conclusion of the Buddhists, who claim to have transcended it by finding it superfluous for the end it aims at. Let us then take, as our example of the completed type, not the monks of the Thebaid, but the mild ascetics of the Buddhist communities. Does not this type, even in its most attractive form, represent a 'second best'? Is not the final judgment that of Plato, that to save oneself is something, but that there is no full achievement unless for the life of the State also the ideal has been brought nearer realisation? When there is nothing in the world but irredeemable tyranny or anarchy, flight from it may be the greatest success possible as far as the individual life is concerned; but this is not the normal condition of humanity. Finally, may not some actual achievement, either practical or, like that of Schopenhauer, speculative, even if accompanied by real imperfections of character, possess a higher human value than the sanctity that rests always in itself?
