Undoubtedly the human soul, not being a function of the brain, and existing by itself, enjoys relative liberty; but this liberty is limited by its faculties, its powers, and its energies; it is determined, according to the causes which decide it, at the moment of the birth of every man. Could one know exactly the faculties of his soul and the circumstances which were to surround his life, one could write beforehand that man's life in all its details. The human organism is the product of the planet. It is not by a Divine fantasy, by a miracle, or by a direct creation that terrestrial man is constituted such as he is. His form, his figure, his weight, his sense, his whole organisation, are derived from the state or condition of your planet, the atmosphere that you breathe, the food that nourishes you, the gravity of the surface of the Earth, the density of terrestrial matter, &c. The human body does not differ anatomically from that of one of the higher mammalia, and if you go back to the origin of species, you will find gradual transformations established by unimpeachable evidence. The whole of terrestrial life, from the mollusc to man, is the development of one single and sole genealogical tree. The human form has its origin in the animal form. Man is the butterfly developed from the chrysalis of the palæontological ages. From this fact the consequence results that on other worlds organic life is different from what it is here, and that their humanities, which, like our own, are the result of forces in activity on each planet, differ absolutely in their forms from that of terrestrial humanity. For example, on the worlds where they do not eat, the digestive apparatus and the intestines do not exist. On the worlds which are very highly electric, the beings inhabiting them are gifted with an electric sense. On others, sight is adapted for the ultra-violet rays, and the eyes have nothing in common with your eyes; they do not see what you see, and they see what you cannot see. The organs are adapted to the functions they have to fulfil. QUÆRENS. We are not, then, the absolute type of creation? Creation itself is, it appears, a perpetual development of forces in activity.
