11. And since Celsus says also that "when ants die the survivors choose a burial ground, and that there they have their family memorials," I must answer that the more he praises the irrational creatures, so much the more, in spite of himself, he exalts the work of that reason which ordered all things, and shows the cleverness of man, which is able by reason to order the natural advantages of the irrational creatures. Why do I say "irrational," seeing that Celsus thinks that the creatures so named by the general consent of mankind are not irrational? Nor does he who promised to discuss the whole range of nature, and boasted of his truthfulness in the title of his book, think that ants, at all events, are without reason. For he speaks of ants talking to one another, and makes the following remarks: "It really is a fact that when they meet they talk to one another, and this is why they never miss their way; so then they have a full measure of reason, and some general notions, and a voice, know what accidents are, and express what they mean." It is indeed true that when two persons talk to one another they use a voice which expresses some meaning, and frequently describes what are called "accidents"; but would it not be very ridiculous to say we find that sort of thing in ants?
