There is one thing that must be thoroughly and fully recognized for this age of the child’s life (Steiner talks here about the first seven years). It is that the physical body creates its own scale of measurement for what is beneficial to it. This it does by the proper development of craving and desire. Generally speaking, we may say that the healthy physical body desires what is good for it. In the growing human being, so long as it is the physical body that is important, we should pay the closest attention to what the healthy craving, desire and delight require. Pleasure and delight are the forces which most rightly quicken and call forth the physical forms of the organs.
In this matter it is all too easy to do harm by failing to bring the child into a right relationship, physically, with his environment. Especially may this happen in regard to his instincts for food. The child may be overfed with things that completely make him lose his healthy instinct for food, whereas by giving him the right nourishment the instinct can be so preserved that he always wants what is wholesome for him under the circumstances, even to a glass of water, and turns just as surely from what would do him harm. Anthroposophical Science, when called upon to build up an art of education, will be able to indicate all these things in detail, even specifying particular forms of food and nourishment. For Anthroposophy is realism, it is no grey theory; it is a thing for life itself.
Thus the joy of the child, in and with his environment, must be reckoned among the forces that build and mould the physical organs. Teachers he needs with happy look and manner, and above all with an honest unaffected love. A love which as it were streams through the physical environment of the child with warmth may literally be said to ‘hatch out’ the forms of the physical organs.
