I. Natural Science and Its Boundaries

Some understanding of the ancient path of development leading into the higher worlds can be acquired by considering the following. At certain ages of life we develop the spirit-and-soul within us to a state of greater freedom, greater independence. During the first years of infancy it works as an organising force in the body, until with the change of teeth it is liberated, becomes free in a certain sense. We then live freely with our Ego in the element of spirit-and-soul, which is now at our disposal, whereas previously it was occupied with harmonising and regulating the body inwardly. But as we grow on into life there arise those factors which in the sphere of ordinary consciousness do not, to begin with, permit the liberated spirit-and-soul to develop to the point of penetrating into the spiritual world. As men in our life between birth and death we must take the path which places us into the outer world as beings qualified and fit for life in that world. We must acquire the faculties which enable us to establish our bearings in the physical world, and also those which can make each of us a useful member in the life of social community with other men.
