What, then, is wrong with you? I tell you, it is this, that you have neglected and corrupted that part of you, whatever it may be, with which we feel desire or aversion, and the impulse to act or not to act. Neglected in what way? By letting it remian ignorant of the true nature of the good, to which it was born, and of the nature of evil, and of what it has as its own and what is not its own.

~ Epictetus
