Lecture I

This throws an extraordinarily important light on a right method of education and teaching. It shows you, that teaching and education must be arranged in a way that it lasts long enough. You can, if you look only out for that which the child takes up from the seventh year to the 14th year, and which occupies him and what he comprehends, teach the child what he wants to grasp at the present moment. But these processes in the metabolic-limb system of man which are first the physical carrier of what has been grasped, leave after seven years. Now something must remain, even when matter has left; must be taken up by the head, must last up to the 21st year. Then again, the physical matter is gone, it must last up to the 28th year, then again matter is gone and it still must last until the 35th year. Now it finally is entirely in the ether body and from there it is not so easily ousted because the ether body is not always excreted in the same way.
