pothesis, that man is a production formed in the course of time; who is peculiar to the globe he inhabits, who is the result of the peculiar laws by which it is directed; who, consequently, can only date his formation as coeval with that of his planet. Existence is essential to the universe, or the total assemblage of matter essentially varied that presents itself to our contemplation; the combinations, the forms, however, are not essential. This granted, although the matter of which the earth is composed has always existed, this earth may not always have had its present form—its actual properties; perhaps it may be a mass detached in the course of time from some other celestial body;—perhaps it is the result of the spots, or those encrustations which astronomers discover in the sun's disk, which have had the faculty to diffuse themselves over our planetary system;—perhaps the sphere we inhabit may be an extinguished or a displaced comet, which heretofore occupied some other place in the regions of space;—which, consequently, was then competent to produce beings very different from those we now behold spread over its surface; seeing that its then position, its nature, must have rendered its productions different from those which at this day it offers to our view.
Whatever may be the supposition adopted, plants, animals, men, can only be regarded as productions inherent in and natural to our globe, in the position and in the circumstances in which it is actually found: these productions it would be reasonable to infer would be changed, if this globe by any revolution should happen to shift its situation. What appears to strengthen this hypothesis, is, that on our ball
