WHAT behaviour, then, is assigned you in return? If you consider yourself as a wolf — to bite again, to throw more stones. But if you ask the question as a man, examine your treasure; see what faculties you have brought into the world with you. Are they dispositions to ferocity? to revenge? When is a horse miserable? When he is deprived of his natural faculties. Not when he cannot crow, but when he cannot run. And a dog? not when he cannot fly, but when he cannot hunt. Is not a man, then, also unhappy in the same manner? Not he who cannot strangle lions, (for he hath received no faculties for this purpose from nature) but who hath lost his rectitude of mind, and fidelity. Such a one is the person who ought to be publicly lamented for the misfortunes into which he is fallen.
