WHAT then, would you have it appear and bear testimony against itself? What means this? If the case be thus, that which serves may be superior to that to which it is subservient; the horse to the rider; the dog to the hunter; the instrument to the musician; or servants to the king. What is it that makes use of all the rest? Choice. What takes care of all? Choice. What destroys the whole man, at one time by hunger; at another by a rope or a precipice? Choice. Hath man, then, anything stronger than this? And how is it possible, that what is liable to restraint should be stronger than what is not? What hath a natural power of hindering the faculty of sight? Both choice, and what depends on choice. And it is the same of the faculties of hearing and speech. And what hath a natural power of hindering choice? Nothing independent on itself, only its own perversion. Therefore choice alone is vice; choice alone is virtue.
