That is what really happened; the main tendency of life is now directed just as much upon the world as earlier it went beyond it; it has been transferred from the invisible to the visible, from the supernatural to the natural. We see this most clearly in the case of religion, which, as though with immanent necessity, runs through the sequence of a predominant transcendent Theism, a Panentheism, a Pantheism--gradually becoming colourless--an Agnosticism, and a Positivism. Everything supernatural disappears from thought, and life is concerned solely with sense experience. Thus, finally, we appear to have arrived at the same point as that from which the Greeks started out: the Monism of the most modern coining, for example, is hardly to be distinguished from the Hylozoism of the ancient Ionian thinkers. But is the whole result of the movement of universal history really only a deception? Has it simply brought us back again, from the false paths that we have tried, without according us any kind of positive profit whatever? We have become men of another kind; we think and feel differently; we have built up a rich culture, have transformed the world, have created a spiritual atmosphere; and we are capable of striving after infinite life and ultimate truth. Could all of this spring out of mere error? If that were so, should we not be compelled to reject the whole of this as phantasy and deception? But if the error was a means and an instrument in the attainment of truth, and if mankind in its going out from itself and in its return to itself is inwardly developed, where does the boundary between truth and error lie, and what is the meaning of the whole? So here again we lapse into uncertainty; history, to other ages a secure support, leads us into still greater doubt.
