Preface

The aim of this essay is to show that everything necessary to explain and account for the world is within the reach of our thinking. The assumption that there are principles which belong to our world, but lying outside it, is revealed as the prejudice of an out-dated philosophy living in vain and illusory dogmas. Kant himself would have come to this conclusion had he really investigated the powers inherent in our thinking. Instead of this, he shows in the most complicated way that we cannot reach the ultimate principles existing beyond our direct experience, because of the way our faculty of knowledge functions. There is, however, no reason for transferring these principles into another world. Kant did indeed refute “dogmatic” philosophy, but he put nothing in its place. This is why Kant was opposed by the German philosophy which followed. Fichte, Schelling and Hegel did not worry in the least about the limits to cognition erected by Kant, but sought the ultimate principles within the world accessible to human reason. Even Schopenhauer, though he maintained that the conclusions of Kant's criticism of reason were eternal and irrefutable truths, found himself compelled to search for the ultimate cause along paths very different from those of Kant. The mistake of these thinkers was that they sought knowledge of the highest truths without having first laid a foundation by investigating the nature of knowledge itself. This is why the imposing edifice of thought erected by Fichte, Schelling and Hegel stands there, so to speak, without foundations. This had a bad effect on the direction taken by the thought of these philosophers. Because they did not understand the significance of the sphere of pure ideas and its relationship to the realm of sense-perceptions, they added mistake to mistake, one-sidedness to one-sidedness. It is no wonder that their all too daring systems could not withstand the fierce opposition of an epoch so ill-disposed toward philosophy; consequently, along with the errors much of real value in their thought was mercilessly swept away.
