Every way, you see, reader, there are difficulties. But two things used to strike me, as unaccountably overlooked by Kant; who, to say the truth, was profound--yet at no time very agile--in the character of his understanding. First, what age now might we take our brother and sister planets to be? For _that_ determination as to a point in _their_ constitution, will do something to illustrate our own. We are as good as they, I hope, any day: perhaps in a growl, one might modestly insinuate--_better_. It's not at all likely that there can be any great disproportion of age amongst children of the same household: and therefore, since Kant always countenanced the idea that Jupiter had not quite finished the upholstery of his extensive premises, as a comfortable residence for a man, Jupiter having, in fact, a fine family of mammoths, but no family at all of 'humans,' (as brother Jonathan calls them,) Kant was bound, _ex analogo_, to hold that any little precedency in the trade of living, on the part of our own mother Earth, could not count for much in the long run. At Newmarket, or Doncaster, the start is seldom mathematically true: trifling advantages will survive all human trials after abstract equity; and the logic of this case argues, that any few thousands of years by which Tellus may have got ahead of Jupiter, such as the having finished her Roman Empire, finished her Crusades, and finished her French Revolution, virtually amounts to little or nothing; indicates no higher proportion to the total scale upon which she has to run, than the few tickings of a watch by which one horse at the start for the Leger is in advance of another. When checked in our chronology by each other, it transpires that, in effect, we are but executing the nice manoeuvre of a start; and that the small matter of six thousand years, by which we may have advanced our own position beyond some of our planetary rivals, is but the outstretched neck of an uneasy horse at Doncaster. This is _one_ of the data overlooked by Kant; and the less excusably overlooked, because it was his own peculiar doctrine,-- that uncle Jupiter ought to be considered a greenhorn. Jupiter may be a younger brother of our mamma; but, if he is a brother at all, he cannot be so very wide of our own chronology; and therefore the first _datum_ overlooked by Kant was--the analogy of our whole planetary system. A second datum, as it always occurred to myself, might reasonably enough be derived from the intellectual vigor of us men. If our mother could, with any show of reason, be considered an old decayed lady, snoring stentorously in her arm-chair, there would naturally be some _aroma_ of phthisis, or apoplexy, beginning to form about _us_, that are her children. But _is_ there? If ever Dr. Johnson said a true word, it was when he replied to the Scottish judge Burnett, so well known to the world as Lord Monboddo. The judge, a learned man, but obstinate as a mule in certain prejudices, had said
