"Hold then the same view of the dog which has lost his master, which has sought him in all the thoroughfares with cries of sorrow, which comes into the house troubled and restless, goes downstairs, goes upstairs; goes from room to room, finds at last in his study the master he loves, and betokens his gladness by soft whimpers, frisks, and caresses.There are barbarians who seize this dog, who so greatly surpasses man in fidelity and friendship, and nail him down to a table and dissect him alive, to show you the Mesaraic veins! You discover in him all the same organs of feeling as in yourself. Answer me, Mechanist, has Nature arranged all the springs of feeling in this animal to the end that he might not feel? Has he nerves that he may be incapable of suffering? Do not suppose that impertinent contradiction in Nature."
