text: But I must stop this preamble and approach the problem under consideration. Men say: "The happy life consists in upright conduct; precepts guide one to upright conduct; therefore precepts are sufficient for attaining the happy life." But they do not always guide us to upright conduct; this occurs only when the will is receptive; and sometimes they are applied in vain, when wrong opinions obsess the soul. Furthermore, a man may act rightly without knowing that he is acting rightly. For nobody, except he be trained from the start and equipped with complete reason, can develop to perfect proportions, understanding when he should do certain things, and to what extent, and in whose company, and how, and why. Without such training a man cannot strive with all his heart after that which is honourable, or even with steadiness or gladness, but will ever be looking back and wavering.
