Our system of nature may be criticised, or rejected. We offer it merely as a personal view, and would not impose it on any reader. The merit of this philosophical and scientific conception, if it has any, consists in the vast synthesis by which it binds together all the living creatures which people the solar world, from the minute plant in which the germ of organization first appears, to the animal; from the animal to the man; and from the man to the series of superhuman and archhuman beings who inhabit the ethereal spheres; and finally, from them to the radiant dwellers in the solar star. In collecting together, on the one hand, all that modern chemistry has learned of the composition of plants, and the physical phenomena of their respiration, and on the other hand, everything which is known of the physical and chemical properties of solar light, the idea struck us that the rays of the sun form the vehicle by whose means the animated germs are placed in the plants. While meditating upon what has been written by the philosophers Charles Bonnet, Dupont de Nemours, and Jean Reynaud, upon the physical condition of resuscitated human beings, and dwelling upon the destiny of men beyond the formidable barrier of the tomb, in short, while drinking at the most various springs of philosophical and scientific knowledge, we have composed this attempt at a new philosophy of the universe.
This system may be erroneous, and another, more logical and more learned, may be substituted for it. But there will remain, we may hope, the synthesis which we have established from all the facts of the physical and moral order which we have collected together, the links by which we attach all the beings of creation one to another, which comprehends both the moral and organic attributes of these beings;--a vast ladder of nature, on whose steps we place everything that has life; the endless circle, in which we link all the rings of the chain of living beings. The theoretic explanation of all these facts, thus grouped, may not perhaps be accepted, but we believe that they are correctly placed in juxtaposition, and that any theory which pretends to explain the universe must be established upon the basis of that grouping. If our explanation be contested, we hope that our synthesis of facts will remain.
