Let us consider the immense space occupied in the lives of animals by their need of alimentation. Many animals, especially those which live in the water, have an incessant need of food. They must eat always, without intermission, or they die of inanition. Among superior animals, the necessity for eating and drinking is less imperious, because the respiratory function comes to their aid, bringing into the body, by the absorption of oxygen and a small proportion of azote, a certain amount of reparative element, as a supplement to alimentary substances. Man profits largely by this advantage. Our respiration is a function of the highest importance, and it bears a great share in the reparation of all our organs. The oxygen which our blood borrows from the air in breathing, contributes largely to our nutrition. The respiratory function in birds is very active, and the organs which exercise it are largely developed, and in their nutrition also oxygen counts largely, and takes the place of a certain quantity of food. It is our belief that the respiration of the ether in which he lives, suffices for the support of the material body of the superhuman being, and that the necessity for eating and drinking has no place in his existence. I do not know whether my reader forms an exact conception of the consequences which would result from the theory, that the superhuman beings whom we are contemplating are exempted from all need of food. Those consequences will be most readily comprehended, if we consider that it is the pressing obligation of procuring food which renders the lives of animals so miserable. Forced incessantly to seek their subsistence, animals are entirely given up to this grovelling occupation; thence come their passions, their quarrels, and their sufferings. It is much the same in the case of man, though in a less degree. The necessity for providing for the aliment of every day, the obligation of earning his daily bread--as the popular phrase has it--is the great cause of the labours and the sufferings of the human species. Supposing that man could live, develop himself, and sustain his life without eating--that the mere respiration of air would supply the waste of his organs--what a revolution would be effected in human society. Hateful passions, wars, and rivalries would disappear from the earth. The golden age, dreamed of by the poets, would be the certain consequence of such an organic disposition.
