At the same time, all capacity for understanding the world in which Christianity set the soul of man disappears. That world was one of pure inwardness, a world in which the fundamental relation of life was that of the spiritual life to its own ideal conception, to absolute spirit; a world in which the questions of character and of the determination of the will were the chief problems. To earlier Christianity that world was anything but a mere "other" world; rather it constituted that which was nearest and most certain; the chief basis of life, from which the world of sense first received its truth and its value. But the more significant the world of sense becomes to man, and the more powerfully it draws his affections to itself, the more does the relation to this world become the fundamental relation of life; the more does that pure inner world fade, and the more it appears to be something artificial, shadowy, something added as an afterthought; and the turning to it comes to be regarded as a flight into an "other" world. Christianity must necessarily be alien and unintelligible to anyone who feels the world which was to Christianity the chief world to be a mere "other" world; for him all the contentions of Christianity are inevitably distorted, and every element of joyful affirmation and heroic victory which it contains obscured; the whole must present a miserable and morbid picture. Now that the centre of life has changed its position in relation to the world, is it possible to avoid the consequences of a growing tendency to displace and dissolve Christianity? The inner world was to Christianity essentially a realm of conviction and decision, a relation of will to will, of personality to personality: free action, in power and love, in guilt and reconciliation, formed the essence of all events and gave to the world a soul. Only as ethical, personal power did the spiritual life appear to find its own depth and to be able to govern the world.
