“Why may not the intelligence of the spheres be ordained for the study of regions and objects unstudied and unknown on earth? Why may not labour have a better commission than to earn its bread by the sweat of its brow? Why may it not pluck its loaf from the bread-fruit tree, or gather its manna from the ground, or draw its wine from the bleeding vessels of the vine, or _inhale its anodyne breath from the paradise gas of its atmosphere_?”[60] And Sir David thus concludes the chapter:— “The difficulties we have been considering, in so far as they are of a religious character, have been very unwisely introduced into the question of a Plurality of Worlds. We are not entitled to remonstrate with the sceptic, but we venture to doubt the soundness of that philosopher’s judgment who thinks that the truths of natural religion are affected by a belief in planetary races, and the reality of that Christian’s faith who considers it to be endangered by a belief that there are other Worlds than his own.” This last paragraph induces us to go so far as to doubt whether Sir David Brewster has addressed his understanding deliberately, to the subject to which so large a portion of the most elaborate reasonings of Dr Whewell have been directed. Sir David does not quarrel with the Essayist’s account of the constitution of man; and we must now see how he deals with the Essayist’s arguments drawn from Geology. Sir David “is not disposed to grudge the geologist even periods so marvellous” as “millions of years required for the formation of strata, provided they be considered as merely hypothetical;” and admits that “our seas and continents have nearly the same locality, and cover nearly the same area, as they did at the creation of Adam;” but demurs to the conclusion that the earth was prepared for man by causes operating so gradually as the diurnal change going on around us. “Why may not the Almighty have deposited the earth’s strata, during the whole period of its formation, by a _rapid_ precipitation of their atoms from the waters which suspended them, so as to reduce the period of the earth’s formation to little more than the united generations of the different orders of plants and animals constituting its organic remains? Why not still further shorten the period, by supposing that plants and animals, requiring, in our day, a century for their development, may in primitive times have shot up in rank luxuriance, and been ready, in a few _days!_ or months! or years, for the great _purpose of exhibiting_, by their geological distribution, the progressive formation of the earth?”[61]
