X. The Tasks of Schools and the Tripartite Social Organism
We have three strictly separate life epochs for the youth of humans. The first includes childhood up to the change of teeth. This change of teeth is accompanied by a much, much more intense intervention in the human organism than current physiology in any way suspects. The whole being of the human being, as it develops from birth to the change of teeth, becomes something quite different, spiritually and mentally and to a certain extent also physically, when it has gone through the change of teeth. The second phase of life is that which extends from the change of teeth to sexual maturity. The third begins with sexual maturity and extends to the end of the second and the beginning of the third decade of life, into the twenties. A more precise study, based on the inner qualities of the human being, of the developing human being, must become the basis of a true pedagogy in future anthropology.
