4. The Threshold In Nature and In Man

The full clarity of thought and idea, to which man owes his consciousness of self, has been achieved by him only in modern times; and now this consciousness of self needs to be carried a step further. The men of old paid particular heed to the training of the will; we have now to press forward, as I emphasised in my “Philosophy of Spiritual Activity,” to pure thinking. We must develop our thinking; it must grow into Imagination, Inspiration and Intuition. And this will bring us once again to a Threshold, a new Threshold into the spiritual world. We must not remain in the world that offers itself for sense-perception and leaves the inner being of Nature beyond the boundaries of knowledge. We must cross another Threshold, the Threshold that lies before our own inner being.
