These cases of actual but misinterpreted experience, at the same time that they naturally must tend to fortify the popular prejudice, would also, by accounting for it, and ingrafting it upon a reasonable origin, so far tend to take from it the reproach of a prejudice. Though erroneous, it would yet seem to us, in looking back upon it, a rational and even an inevitable opinion, having such plausible grounds to stand upon; plausible, I mean, until science and accurate examination of the several cases had begun to read them into a different construction. Yet, on the other hand, in spite of any colorable excuses that may be pleaded for this prejudice, it is pretty plain that, after all, there is in human nature a deep-laid predisposition to an obstinate craze of this nature. Else why is it that, in every age alike, men have asserted or even assumed the downward tendency of the human race in all that regards _moral_ qualities. For the _physical_ degeneration of man there really were some apparent (though erroneous) arguments; but, for the moral degeneration, no argument at all, small or great. Yet a bigotry of belief in this idle notion has always prevailed amongst moralists, pagan alike and Christian. Horace, for example, informs us that "Aetas parentum, pejor avis, tulit Nos nequiores--mox daturos Progeniem vitiosiorem." The last generation was worse, it seems, than the penultimate, as the present is worst than the last. We, however, of the present, bad as we may be, shall be kept in countenance by the coming generation, which will prove much worse than ourselves. On the same precedent, all the sermons through the last three centuries, if traced back through decennial periods, so as to form thirty successive strata, will be found regularly claiming the precedency in wickedness for the immediate period of the writer. Upon which theories, as men ought physically to have dwindled long ago into pygmies, so, on the other hand, morally they must by this time have left Sodom and Gomorrah far behind. What a strange animal must man upon this scheme offer to our contemplation; shrinking in size, by graduated process, through every century, until at last he would not rise an inch from the ground; and, on the other hand, as regards villany, towering evermore and more up to the heavens. What a dwarf! what a giant! Why, the very crows would combine to destroy such a little monster.
