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 (κρίματα).

Now we ought to work at something like this in the body also, as far as we can. It was impossible for the defluxions of the nose not to run when man has such a mixture in his body. For this reason nature has made hands and the nostrils themselves as channels for carrying off the humours. If then a man sucks up the defluxions, I say that he is not doing the act of a man. It was impossible for a man's feet not to be made muddy and not be soiled at all when he passes through dirty places. For this reason nature (God) has made water and hands. It was impossible that some impurity should not remain in the teeth from eating: for this reason, she says, wash the teeth. Why? In order that you may be a man and not a wild beast or a hog. It was impossible that from the sweat and the pressing of the clothes there should not remain some impurity about the body which requires to be cleaned away. For this reason water, oil, hands,
