We here desire to claim as a positive outcome of philosophy that it has at last acquired the clear and exact knowledge that a socalled infinite spirit, in the religious sense, is a fantastic, unscientific conception. In the natural sense of the word, the human powers of understanding are universal and yet in spite of their universality they are, quite naturally, limited. The human understanding has its limits, why should it not? Only drop the illusion that a dark mystery is concealed beyond these limits. The understanding is a force among others, and everything that is located alongside of other things is limited and restricted by them. We can understand everything, but we can also touch, see, hear, feel, and taste everything. We also have the power of moving about, and other qualities. One art limits another, and yet each is unlimited in its own field. The various human powers belong together and constitute together the human wealth. Be careful not to separate the power of understanding from other natural powers. In a certain sense it must be separated, because it is the special object of our study, but it must always be remembered that such a separation has only a theoretical value. Just as our power of vision can see everything, so our understanding can grasp everything. Let us look a little closer at this statement. How can we see everything? Not from any single standpoint. In that sense our powers of vision are limited. But what is not visible in the distance, becomes so on approaching nearer to it. What one eye cannot see, that of others can, and what is invisible to the naked eye, is revealed by the telescope and microscope. Nevertheless the vision remains limited, even though it may be the sharpest, and armed with the best artificial means. Even if we regard all the eyes of the past and future generations of humanity as organs of the universal human vision, this vision still remains limited. Nevertheless, no one will complain about the limits of human power, because we cannot see sounds with our eyes or hear the light with our ears.
