What is the result? Look for a moment at the Earth. See what sorrow, what desolation! What a world of misery and brutality! Multitudes bowed down with bent backs to the soil, which they dig with toil and pain, that they may gain their daily bread! All these heads bent down to the grossness of matter, in place of being raised up to the contemplation of nature! All these efforts and these labours, bringing in their wake feebleness and disease! All this traffic to amass a little gold at the expense of others! Man taking advantage of his brother man! Castes, aristocracies, robbery and ruin, ambitions, thrones, wars! In a word, personal interests, always selfish, often sordid, and the reign of matter over mind. Such is the normal state of the Earth, a condition forced by the law which rules over your bodies, compelling you to kill in order to live, and to prefer the possession of material goods that cannot be earned beyond the grave, to the possession of intellectual gifts, which the soul can keep as a rich and inalienable possession.
Quærens. You speak, master, as if you thought it were possible to live without eating.
Lumen. Do you, then, believe that the beings of every world in space are subject to an operation so ridiculous as this? Happily, in many of the worlds, the spirit is not subjected to such ignominy.
Atmospheric nutrition.
It is not so difficult as you may suppose, on first thoughts, to believe in the possibility of atmospheric nutriment. The maintenance of life among man and the animals depends upon two causes, respiration and nutrition. The first is found naturally in the atmosphere; the second is derived from nourishment. Nutrition produces blood; from the blood come the tissues, the muscles, the bones, the cartilages, the flesh, the brain, the nerves, in a word, the organic constituents of the body. The oxygen we breathe can itself be considered as a nutritive substance, inasmuch as it combines with the principal aliments absorbed by the stomach, and completes the formation of the blood and the development of the tissues.
The process of alimentation.
Now, to imagine nutrition passing entirely into the domain of the atmosphere, it is only necessary to observe that, as a whole, a complete aliment is made up of albumen, of sugar, of fat, and of salt, and to imagine also that an atmospheric fluid, in place of being composed of azote and of oxygen only, should be formed of these different substances in a gaseous state. These aliments are found in the solids that you absorb; digestion is the function which separates them, and which causes them to assimilate with the organs to which they belong. When, for example, you eat a morsel of bread, you introduce into your stomach a grain of starch, a substance insoluble in water, and which is not found in the blood. The saliva, and the pancreatic juice, transform the insoluble starch into soluble sugar. The bile, the pancreatic juice, and the intestinal secretions, change the sugar into fat. Both sugar and fat are present in the blood, and it is by the processes of alimentation that substances are separated and assimilated in your body.
It astonishes you, my friend, that after living five years—according to terrestrial reckoning—in the celestial world, I can remember all these material terms, and condescend to make use of them. But the memories that I have brought from the Earth are still vivid, and as we speak on this occasion on a question of organic physiology, I do not feel ashamed of calling things by their own names.
If, then, we suppose that in place of being combined or mixed in the constitution of bodies, solid or liquid, these aliments could be found in a gaseous state in the composition of the atmosphere, we should create by this means nutritive atmospheres, which would dispense with digestion and its attendant coarse and humiliating functions.
That which man is capable of imagining in the restricted sphere of his observation, Nature has put in practice in more than one spot of the universe.
