And this injunction which the lawgiver laid down, is of necessity applicable to all wise men; for they have their sense of sight purified, their sense of hearing thoroughly Genesis vii. 2. examined, and so on with all the rest of their outward senses. Accordingly, they have the faculty of speech free from all spot or stain, and their appetites which prompt them to indulge the passions in a state of due subjection to the law.

And every one of the seven outward senses is in one respect male, and in another, female. For when they are stationary, or when it is in motion, they are stationary while quiescent in sleep, and they are in motion while they are energising in their waking state; and the one in accordance with habit and tranquillity, as being subject to passion, is called the female; and the one which exists according to motion and energy, as one that is only conceived in action, is called the male.
