The leading distinction[4] between dog and man, after and perhaps before the different duration of their lives, is that the one can speak and that the other cannot. The absence of the power of speech confines the dog in the development of his intellect. It hinders him from many speculations, for words are the beginning of metaphysic. At the same blow it saves him from many superstitions, and his silence has won for him a higher name for virtue than his conduct justifies. The faults of the dog[5] are many. He is vainer than man, singularly greedy of notice, singularly intolerant of ridicule, suspicious like the deaf, jealous to the degree of frenzy, and radically devoid of truth. The day of an intelligent small dog is passed in the manufacture and the laborious communication of falsehood; he lies with his tail, he lies with his eye, he lies with his protesting paw; and when he rattles his dish or scratches at the door his purpose is other than appears. But he has some apology to offer for the vice. Many of the signs which form his dialect have come to bear an arbitrary meaning, clearly understood both by his master and himself; yet when a new want arises he must either invent a new vehicle of meaning or wrest an old one to a different purpose; and this necessity frequently recurring must tend to lessen his idea of the sanctity of symbols. Meanwhile the dog is clear in his own conscience, and draws, with a human nicety, the distinction between formal and essential truth. Of his punning perversions, his legitimate dexterity with symbols, he is even vain; but when he has told and been detected in a lie, there is not a hair upon his body but confesses guilt. To a dog of gentlemanly feeling theft and falsehood are disgraceful vices. The canine, like the human, gentleman demands in his misdemeanours Montaigne's "_je ne sais quoi de genéréux_."[6] He is never more than half ashamed of having barked or bitten; and for those faults into which he has been led by the desire to shine before a lady of his race, he retains, even under physical correction, a share of pride. But to be caught lying, if he understands it, instantly uncurls his fleece.
