Atmospheric Composition, Organ Systems, and Healing Substances
You already know, more or less, the particular metals which share in the upbuilding—the interior upbuilding—of the human organism They do not include—with one exception, namely iron—those to which I have referred as in some way the most important ones: lead, tin, copper, quicksilver, silver and gold are not directly engaged in the functioning of the human organism, but have their part in us, nevertheless. Take, for instance, that substance which contributes to the peripheral formations of the human frame; we refer to silicon, with which I have dealt already. Now the processes within us are not bounded by our skins; man is interwoven with the whole web of universal processes. Just as the substances mentioned above are of significance internally, so also the main metals enumerated here, are effective upon man although external to our organism. The part of the mediator is given to iron. Iron plays the mediating role between the sphere within the boundary of the human skin, and that outside this boundary We may therefore maintain that the whole pulmonary System—“pulmonary man,” possessing the urge to become a whole man—is strongly linked with the whole human relationship to the universal life of nature. If we regard only what becomes visible in dissecting the body, we are taking for the whole, what is only a part. The visible body is not the whole, it is that part of man which is opposed to extra-human agencies; to the operation of lead, tin, copper and so forth, which are external to our bodies. Even if we look at the human organisation only from the point of view of natural science, we must never regard man as bounded by the epidermis. We must take into account not only the workings acting from within, outwards, but also all these workings which give a general direction to his organic processes. That the latter play an important part may be realised in the light of the following facts.
