V. Connections Between Organic Processes and the Mental Life of Man

When speaking of the power of memory, I drew attention to the surface of the organs. In a certain sense everything experienced strikes the surfaces, is reflected, and that leads to recollections. But something enters the organism at the same time. In ordinary life this is transmuted, undergoes a metamorphosis, so that the organ produces a secretion. The organs having this function are mostly glandular. They have an inner secretion, which during life is changed into force. But not everything is thus transformed into organic metabolism, etc. Certain organs take up instead something which becomes latent within them, and constitutes an inner force; for example, all thoughts connected mainly with our perception of the outer world through which we form images of outer objects. The forces developed in these thoughts are, in a certain manner, stored up within the lungs.
