of a rogue with a man of honor: "Other things being equal, an honest man has this advantage over a knave, that he understands more of human nature: for he knows that _one_ honest man exists, and concludes that there must be more; and he also knows, if he is not a mere simpleton, that there are some who are knavish. But the knave can seldom be brought to believe in the existence of an honest man. The honest man _may_ be deceived in particular persons, but the knave is _sure_ to be deceived whenever he comes across an honest man who is not a mere fool." "Man is
a fawning dog, a roaring lion, a thieving fox, a robbing wolf, a dissembling crocodile, a treacherous decoy, and a rapacious vulture." This was the poet Cowley's opinion. "Of all the animals" scolds Boileau, "which fly in the air, walk on the ground, or swim in the sea, from Paris to Peru, from Japan to Rome, the most foolish animal, in my opinion, is man." People must be very bad, indeed, who get opinions as low as the two last quoted. That rapacious vulture George Peabody! that dissembling crocodile William Cowper! that robbing wolf Girard! that thieving fox Charles Sumner! that fawning dog Napoleon Bonaparte! and those most foolish animals Louis Agassiz and Isaac Newton! It does not well become the weakest links in a chain to boast that they gauge that chain's strength, for the chain can be greatly strengthened, upon this easy discovery of those weak links, by simply dropping them out of connection.
And now comes the query: "What is man?" He has always been more or less at a loss for some striking and succinct statement of his peculiar characteristics--of the mark that separates him from other animals. Diogenes Laertius says that Plato having defined man to be a two-legged animal without feathers, he (Diogenes) plucked a cock, and, bringing him into the school, said "Here is Plato's man." From this joke there was added to the definition "With broad flat nails." Even this definition is just as faulty, as it does not exclude many species of the monkey. Again it was thought that man was the only being who laughs. Says Addison, poetically: "Man is the merriest species of the creation; all above and below him are serious." But scientists refuse to accept this distinction as accurate. "Man is an animal
