"What, again, of your not abstaining yourselves from the slaughter of lice, bugs, and fleas? You think it a sufficient excuse for this to say that these are the dirt of our bodies. But this is clearly untrue of fleas and bugs; for every one knows that these animals do not come from our bodies. Besides, if you abhor sexual intercourse as much as you pretend to do, you should think those animals all the cleaner which come from our bodies without any other generation; for although they produce offspring of their own, they are not produced in ordinary generation from us. Again, if we must consider as most filthy the production of living bodies, still worse must be the production of dead bodies. There must be less harm, therefore, in killing a rat, a snake, or a scorpion, which you constantly say come from our dead bodies. But to pass over what is less plain and certain, it is a common opinion regarding bees that they come from the carcases of oxen; so there is no harm in killing them. Or if this too is doubted, every one allows that beetles, at least, are bred in the ball of mud which they make and bury. You ought therefore to consider these animals, and others that it would be tedious to specify, more unclean than your lice; and yet you think it sinful to kill them, though it would be foolish not to kill the lice. Perhaps you hold the lice cheap because they are small. But if an animal is to be valued by its size, you must prefer a camel to a man."
