I. Guiding Thoughts on the Method of Presentation

In the fourth epoch the emerging natural sciences add a view of nature to the philosophical world picture that gradually senses its own independent ground. As this nature-picture develops, it retains nothing of a world in which the self-conscious ego (the human soul experiencing itself as a self-conscious entity) must recognize itself. In the first epoch the human soul begins to detach itself from the experienced external world and to develop a knowledge concerned with the inner life of the soul. This independent soul life finds its power in the awakening thought element. In the fourth period a picture 'of nature emerges that has detached itself in turn from the inner soul life. The tendency arises to think of nature in such a way that nothing is allowed to be mixed into its conception that has been derived from the soul and not exclusively from nature itself. Thus, the soul is, in this period, expelled from nature, and with its inner experiences confined to its subjective world. The soul is not about to be forced to admit that everything it can gain as knowledge by itself can have a significance only for itself. It cannot find in itself anything to point to a world in which this soul could have its roots with its true being. For in the picture of nature it cannot find any trace of itself.
