A quote
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.
