Discourses: Book 4 11 : 7
Why, look you, nature has not made dirty even the animals which associate with man. A horse doesn't roll around in the mud, does he? or a highly bred dog? No, but the hog, and the miserable rotten geese, and worms, and spiders, the creatures farthest removed from association with human beings. Do you, then, who are a human being, wish to be not even an animal of the kind that associates with men, but rather a worm, or a spider? Will you not take a bath somewhere, some time, in any form you please? Will you not wash yourself? If you don't care to bathe in hot water, then use cold. Will you not come to us clean, that your companions may be glad? What, and do you in such a state go with us even into the temples, where it is forbidden by custom to spit or blow the nose, yourself being nothing but a mass of spit and drivel?
