4. The Rise of Spiritualism. The Need for the Science of the Spirit

As a matter of fact, those people think but little in accord with reality who are not willing to admit that when we are as far removed in time from Copernicus as Copernicus was from Ptolemy, men will again have a different concept of the heavens. The development of humanity is in constant flux and by that time, the Copernican system will be regarded just as the Ptolemaic system was regarded by the Copernicans. Even though it gives the impression today of being pure nonsense when one says another world conception, which will differ as much from the Copernican as the Copernican from the Ptolemaic, will replace the Copernican world conception in future, this truth is nevertheless quite evident to those who have an inner comprehension of what lives and weaves in the growth of humanity. The special method of applying merely the intellect to natural phenomena in an external way, which has created the natural science of the last three or four centuries, represents the faculty that belongs to those centuries. It is clear to those who know how humanity advances that mankind was actually ripe from the middle of the nineteenth century on for the gradual development of other faculties. But man must increasingly take his own affairs in hand. More than in any previous age he is given the task today of doing something toward adding fresh faculties to those gained in the last three or four centuries. Why have these faculties arisen that can keenly, penetratingly and logically master the outer surface of phenomena so that they can then be expressed in natural laws? For what purpose have these faculties appeared that penetrate so little below the surface of things, yet observe so meticulously and scientifically all that lies on the surface? They have appeared because only by their means can man go through a certain stage of his development.
