II. The Three Fundamental Forces in Education

It is not possible, naturally, to educate or give instruction if in our education and instruction we are not able to sense inwardly the whole human being. For during the period of a child's development this whole man needs to be considered far more than later on. We know this whole man embraces the ego, the astral body, the etheric body and the physical body. These four members of our human nature are of course not subject to uniform development but unfold in quite different ways. We must distinguish accurately between the development of the physical and the etheric bodies and that of the astral body and ego. The outer signs of this differentiated development are furnished—as you know from the various hints I have given here or there—by the change of teeth and by that alteration in the human being which is announced by the change of voice accompanying sexual maturity in the male, appearing as clearly but in a different way in the female. The nature of this phenomenon in the female organism is fundamentally the same as in the man's change of voice, but it emerges in a broader way, not perceptible in a single organ only, as with the man, but spread more over the entire organism. You know that between the change of teeth and the change of voice or puberty lies the period of instruction with which we have to do preferably in elementary education. But the years that follow the change of voice (or what corresponds to it in the female organism) must also be given our close attention in education and teaching.
