consisting, as at present, of a spiritual nature residing in a corporeal frame.” We must, therefore, find for the race of Adam, “_if not for the races which preceded him_!”[50] “a material home upon which he may reside, or from which he may travel to other localities in the universe.” That house, he says, cannot be the earth, for it will not be big enough—there will be such a “population as the habitable parts of our globe could not possibly accommodate;” wherefore, “_we can scarcely doubt_ that their future abode must be on some of the primary or secondary planets of the solar system, whose inhabitants have ceased to exist, like those on the earth; or on planets which have long been in a state of preparation, as our earth was, for the advent of intellectual life.” Here, then, is “the creed of the philosopher,” as well as “the hope of the Christian.” Passing, according to the order adopted in this paper, from the first chapter (“Religious Aspect of the Question”), we alight on the seventh, entitled “_Religious Difficulties_.” We entertain too much consideration for Sir David Brewster to speak harshly of anything falling from his pen; but we think ourselves justified in questioning whether this chapter—dealing with speculations of an awful nature, among which the greatest religious and philosophical intellects tremble as they “go sounding on their dim and perilous way”—shows him equal to cope with his experienced opponent, whom every page devoted to such topics shows to have fixed the DIFFICULTY with which he proposed to deal, fully and steadily before his eyes, in all its moral, metaphysical, and philosophical bearings, and to have discussed it cautiously and reverently. We shall content ourselves with briefly indicating the course of observation on that “difficulty” adopted by Sir David Brewster, and leaving it to the discreet reader to form his own judgment whether Sir David has left the difficulty where he found it, or removed, lessened, or enhanced it. Dr Whewell, in his _Dialogue_, thus temperately and effectively deals with this section of his opponent’s lucubrations:— “His own solution of the question concerning the redemption of other worlds appears to be this, that the provision made for the redemption of man by what took place upon earth eighteen hundred years ago, may have extended its influence to other worlds.
