These questions, of which a myriad similar ones might be asked by any one, we leave to our geological readers; and hasten to inform them, that in involuntary homage to the powerful reasonings of his opponent, Sir David Brewster is fain to question the “inference that man did not exist during the period of the earth’s formation;”[62] and to suggest that “there may have existed intellectual races in present unexplored continental localities, or the immense regions of the earth now under water!”—“The future of geology may be pregnant with startling discoveries of the remains of intellectual races, even _beneath_ the primitive Azoic[63] formations of the earth!... Who can tell what sleeps beyond? Another creation may be beneath! more glorious creatures may be entombed there! the mortal coils of beings more lovely, more pure, more divine than man, may yet read to us the unexpected lesson that we have not been the first, and may not be the last of the intellectual race!”[64] Is he who can entertain and publish conjectures like these, entitled to stigmatise so severely those of other speculators—as “inconceivable absurdities, which no sane mind can cherish—suppositions too ridiculous even for a writer of romance!” This wild license given to the fancy may not be amiss in a poet, whose privilege it is that his “eye in a fine phrenzy rolling” may “give to airy nothing a local habitation, and a name:”—but when set in the scale against the solemnly magnificent array of facts in the earth’s history established by Geology, may be summarily discarded by sober and grave inquirers.
