I. Guiding Thoughts on the Method of Presentation

The evolution of thought life has proceeded through four epochs. In the first, thought is experienced as a perception coming from without. In this phase the human soul finds its self-dependence through the thought process. In the second period, thought had exhausted its power in this direction. The soul now becomes stronger in the experience of its own entity. Thought itself now lives more in the background and blends into self knowledge. It can no longer be considered as if it were an external perception. The soul becomes used to experiencing it as its own product. It must arrive at the question of what this product of inner soul activity has to do with an external world. The third period passes in the light of this question. The philosophers develop a cognitive life that tests thought itself with regard to its inner power. The philosophical strength of the period manifests itself as a life in the element of thought as such, as a power to work through thought in its own essence. In the course of this epoch the philosophical life increases in its ability to master the element of thought. At the beginning of the fourth period the cognitive self-consciousness, on the basis of its thought possession, proceeds to form a philosophical world picture. This picture is now challenged by a picture of nature that refuses to accept any element of this self-consciousness. The self-conscious soul, confronted with this nature picture, feels as its fundamental question, “How do I gain a world picture in which both the inner world with its true essence and the external nature are securely rooted at the same time?” The impulse caused by this question dominates the philosophical evolution from the beginning of the fourth period; the philosophers themselves may be more or less aware of that fact. This is also the most important impulse of the philosophical life of the present age.
