ABOUT PURITY (CLEANLINESS).—Some persons raise a question whether the social feeling is contained in the nature of man; and yet I think that these same persons would have no doubt that love of purity is certainly contained in it, and that if man is distinguished from other animals by anything, he is distinguished by this. When then we see any other animal cleaning itself, we are accustomed to speak of the act with surprise, and to add that the animal is acting like a man; and on the other hand, if a man blames an animal for being dirty, straightway, as if we were making an excuse for it, we say that of course the animal is not a human creature. So we suppose that there is something superior in man, and that we first receive it from the gods. For since the gods by their nature are pure and free from corruption, so far as men approach them by reason, so far do they cling to purity and to a love (habit) of purity. But since it is impossible that man’s nature ([Greek: ousia]) can be altogether pure, being mixed (composed) of such materials, reason is applied, as far as it is possible, and reason endeavors to make human nature love purity. The first then and highest purity is that which is in the soul; and we say the same of impurity. Now you could not discover the impurity of the soul as you could discover that of the body; but as to the soul, what else could you find in it than that which makes it filthy in respect to the acts which are her own? Now the acts of the soul are movement towards an object or movement from it, desire, aversion, preparation, design (purpose), assent. What then is it which in these acts makes the soul filthy and impure? Nothing else than her own bad judgments ([Greek: chrimata]). Consequently the impurity of the soul is the soul’s bad opinions; and the purification of the soul is the planting in it of proper opinions; and the soul is pure which has proper opinions, for the soul alone in her own acts is free from perturbation and pollution.
