I. Soul and Spirit in the Human Physical Constitution

This Tone Ether or Chemical Ether is essentially active in our fluid organism. We can therefore make the following distinction: In our fluid organism lives our own etheric body; but in addition there penetrates into it (the fluid organism) from every direction the Tone Ether which underlies the tone. Please distinguish carefully here. We have within us our etheric body; it works and is active by giving rise to thoughts in our fluid organism. But what may be called the Chemical Ether continually streams in and out of our fluid organism. Thus we have an etheric organism complete in itself, consisting of Chemical Ether, Warmth Ether, Light Ether, Life Ether, and in addition we find in it, in a very special sense, the Chemical Ether which streams in and out by way of the fluid organism.
