4. Man's inner Cosmic System

Many people, it is true, imagine that they have to do with some sort of indeterminate substance taken in as food, a substance quite neutral in its relation to us which simply waits, when we have once taken it in, till we are able to digest it. But such is not the case. Articles of food are, after all not just bricks which serve in some sort of way as building material for the construction they are to help in erecting. Bricks are included in the architect's plan in any way he pleases to use them because they represent in relationship to the building a mass in itself quite inert. This is not true, however, of nutritive matter in its relation to the human being. For every particle of substance we have in our environment has certain inner forces, its own conformity to law. This is the essential element in any substance that it has its own inner laws, its own inner activities. Accordingly, when we bring external nutritive substances into our organism, when we insert them into our own inner activity, so to speak, they do not simply consent to this at once as a matter of course but attempt first to develop their own laws, their own rhythms and their own inner forms of movement.
