This prejudice, of course, is not without its reason. The philosophers, nearly one and all, seem to have banded themselves into a sort of imaginary freemasonry, whose portals they bar to any one refusing to robe his thoughts in a garment of technical speech. Moreover, at the very gateway of their guild there looms before the timorous the fear of a hideous initiation, the cold douche of logic, and the memorizing of hateful terms. There can therefore be no stronger proof of Schopenhauer's ability than that which is contained in the fact that he successfully eluded all these stale abuses, and turned one of the heaviest kinds of writing into one of the most agreeable.

Indeed, Schopenhauer is not only one of the most profound thinkers of the essentially profound nineteenth century, but, what is still more noteworthy, he is an exceptionably fascinating teacher. His spacious theories and tangential flights are, of course, not such as charm the reader of the penny dreadful; but any one who is interested in the drama of evolution and the tragi-comedy of life will, it is believed, find in him a fund of curious information, such as no other thinker has had the power to convey.

He has, it is true, made the most of the worst; but beyond this reproach, but one other of serious import remains to be brought against him, and that is that though he has been dead and buried for very nearly a quarter of a century, he is still on the outer margin of his epoch. For this he is not, of course, entirely to blame. There are among thinkers many pleasant optimists still, who form a respectable majority; to be sure, a wise man once said that in considering a new subject the minority were always right; but, disregarding for the moment the fallacy of believing that this world is the best one possible, it cannot but be admitted that scientific pessimism is still in its infancy. It has yet many prejudices to disarm, and many errors of its own to correct. Like meaner things, it must mature. For this it has ample time.

Berkeley says that few men think, yet all have opinions; and it is now very frequently asserted that when more is thought, not only there will not be such a diversity of opinion, but at that time Pessimism, as the religion of the future, will begin its sway.

It has been elsewhere noted that the effect of Kant's philosophy was not dissimilar to that of a successful operation on cataract, and the aim of the "World as Will and Idea" is to place in the hands of those on whom that operation has been satisfactorily performed a pair of such spectacles as are suitable to convalescent eyes. Schopenhauer is therefore in a measure indebted to Kant, as also, it may be added, to Plato, and the sacred books of the Hindus.

In saying, however, that Schopenhauer is indebted to Kant, it is well to point out that Schopenhauer begins precisely where Kant left off. Kant's great merit consisted in distinguishing the phenomenon from the thing-in-itself, or in other words, in showing the difference between that which seems and that which is.[8] For the inaccessible thing-in-itself he had no explanation to offer. He called it the Ding an sich, regarded it as the result of an unintelligible cause, and then left it to be a bugbear to every student of his philosophy.

This unpleasant Ding an sich was exorcised, and well-nigh banished for good and all, by Fichte and Hegel; but Schopenhauer reëstablished the incomprehensible factor on a fresh basis, christened it "Will," and asserted it to be the creator of all that is, and at once independent, free, and omnipotent; in other words, the interior essence of the world of which Christ crucified is the sublime symbol. Thus disposed of, the Ding an sich may now be left to take care of itself, and the examination of the great theory begun.

Schopenhauer opens his philosophy with the formula, "The world is my idea;" a formula which, it may be noted, condenses in the fewest possible words all that is worth condensing of the idealism of Germany. Beginning in this manner it is evident that he proposes to show neither whence the world comes nor whither it tends, nor yet why it is, but simply, what it is. The question has been asked before. According to Schopenhauer, the world is made up of two zones, the real and the ideal; and it may here be said that over the real and the ideal Schopenhauer successfully read the banns.

To return, however, to the opening formula. "The world is my idea" is a truth which holds good for everything that lives and thinks, but which, however, is appreciable only by man. When appreciated, it is at once clear that what we know is neither a sun nor an earth, for we have at best an eye which sees the one, and a hand which feels the other. In brief, we are unacquainted with either forms or colors; we have but senses which represent them to us, while objects exist for us merely through the medium of the intelligence. Indeed, as Schopenhauer has said, no other truth is more certain and less in need of proof than this,—that the whole world is simply the perception of a perceiver; in a word, idea.

Emerson says that the frivolous make themselves merry with this theory; and it must be admitted that at first it does not seem quite satisfactory to be told that the world in which we live is nothing more nor less than a cerebral phenomenon, which man carries with him to the tomb, and which, in the absence of a perceiver, would not exist at all. To arrive, however, at a clear understanding of the purely phenomenal existence of the exterior world, it will suffice to represent to one's self the world as it was when entirely uninhabited. At that time it was necessarily without perception. Later, there sprang up a great quantity of plants, upon which the different forces of light, air, humidity, and electricity acted according to their nature. If, now, it be remembered how impressionable plants are to these agents, and how thought leads by degrees to sensation and thence to perception, immediately then the world appears representing itself in time and space. Or, reverse the argument and imagine that the dream of the poet is realized, that nations have disappeared, and that every living thing has ceased to be, while beneath the sun's unchanging stare, and enveloped in the sky's bland, pervasive blue, the earth with her continents and archipelagoes continues to revolve in space. Under such circumstances it would naturally seem as though the universe subsisted still. But if the question is examined more closely, it will perhaps be admitted that these things remain as they are only on condition of being seen and felt. For supposing one spectator present, but of a different mental organization from our own, then the entire scene is changed; suppress him, and the whole spectacle tumbles into chaos.
