34. Or will the objection be made in this way; that such a peculiar dignity and importance given to the earth is contrary to the analogy of creation;--that since there are so many globes, similar to the earth,--like her, revolving round the sun, like her, revolving on her axes, several of them, like her, accompanied by satellites; it is reasonable to suppose that their destination and office is the same as hers;--that since there are so many stars, each like the sun, a source of light, and probably of heat, it is reasonable to suppose that, like the sun, they are the centres of systems of planets, to which their light and heat are imparted, to uphold life:--is it thought that such a resemblance is a strong ground for believing that the planets of our system, and of other systems, are inhabited as the earth is? If such an astronomical analogy be insisted on, we must again have recourse to geology, to see what such analogy is worth. And then, we are led to reflect, that if we were to follow such analogies, we should be led to suppose that all the successive periods of the earth's history were occupied with life of the same order; that as the earth, in its present condition, is the seat of an intelligent population, so must it have been, in all former conditions. The earth, in its former conditions, was able and fitted to support life; even the life of creatures closely resembling man in their bodily structure. Even of monkeys, fossil remains have been found. But yet, in those former conditions, it did not support human life. Even those geologists who have dwelt most on the discovery of fossil monkeys, and other animals nearest to man, have not dreamt that there existed, before man, a race of rational, intelligent, and progressive creatures. As we have seen, geology and history alike refute such a fancy. The notion, then, that one period of time in the history of the earth must resemble another, in the character of its population, because it resembles it in physical circumstances, is negatived by the facts which we discover in the history of the earth. And so, the notion that one part of the universe must resemble another in its population, because it resembles it in physical circumstances, is negatived as a law of creation. Analogy, further examined, affords no support to such a notion. The analogy of time, the events of which we know, corrects all such guesses founded on a supposed analogy of space, the furniture of which, so far as this point is concerned, we have no sufficient means of examining.
