7. The Conscious Life of Man
We may, accordingly, expect to find that something is incorporated into the blood which, we might say, does not manifest itself there as if it were due to the influence of processes working up from the lower depths of our nature, but rather as if it were due to the influence of external macrocosmic laws and vital activities. We must have in our blood, therefore, something that is similar in character and action to direct external processes, which take their course outside of us in the same way in which they gradually come later to take their course within our organism. That is, there must be physical, chemical, inorganic processes which take their course within our blood, which are necessary to enable our ego to take part in the physical world. Thus we shall have to seek in the blood for processes wherein substances can act through their physical-sensible character, in accordance with what they are in the macrocosm. And this we do find, as a matter of fact, in that something is presented to us in the red corpuscles which shows us that it is just beginning to live, and is at the point where it passes over to the state of lifelessness. And from the other side of the tablet something is incorporated into the blood which we may call a process easily comparable to an external process of combustion. In short we have in the blood, disposed on the other side, and recognisable even physically, everything that makes man a physical-sensible being through the fact that in the blood he has an instrument for his ego which is living in this physical-sensible world.
