With all philosophers it is precisely the “system” which is perishable; and for the simple reason that it springs from an imperishable desire of the human mind — the desire to overcome all contradictions. But if all contradictions are once and for all disposed of, we shall have arrived at so-called absolute truth — world history will be at an end. And yet it has to continue, although there is nothing left for it to do — hence, a new, insoluble contradiction. As soon as we have once realized — and in the long run no one has helped us to realize it more than Hegel himself — that the task of philosophy thus stated means nothing but the task that a single philosopher should accomplish that which can only be accomplished by the entire human race in its progressive development — as soon as we realize that, there is an end to all philosophy in the hitherto accepted sense of the word. One leaves alone “absolute truth”, which is unattainable along this path or by any single individual; instead, one pursues attainable relative truths along the path of the positive sciences, and the summation of their results by means of dialectical thinking. At any rate, with Hegel philosophy comes to an end; on the one hand, because in his system he summed up its whole development in the most splendid fashion; and on the other hand, because, even though unconsciously, he showed us the way out of the labyrinth of systems to real positive knowledge of the world.
