The other parts, because deep mysteries, we shall now pass by; but let us look upon the various kinds of animals, and we shall find almost every one beginning from an egg,--fowls and fishes; land animals, as lizards; amphibious, as crocodiles; some with two legs, as a cock; some without any, as a snake; and some with many, as a locust. And therefore in the solemn feast of Bacchus it is very well done to dedicate an egg, as the emblem of that which begets and contains everything in itself. To this discourse of Firmus, Senecio replied: Sir, your last similitude contradicts your first, and you have unwittingly opened the world (instead of the door, as the proverb goes) against yourself. For the world was before all, being the most perfect; and it is rational that the perfect in Nature should be before the imperfect, as the sound before the maimed, and the whole before the part. For it is absurd that there should be a part when there is nothing whose part it is; and therefore nobody says the seed's man or egg's hen, but the man's seed and hen's egg; because those being after these and formed in them, pay as it were a debt to Nature, by bringing forth another. For they are not in themselves perfect, and therefore have a natural appetite to produce such a thing as that out of which they were first formed; and therefore seed is defined as a thing produced that is to be perfected by another production. Now nothing can be perfected by or want that which as yet is not. Everybody sees that eggs have the nature of a concretion or consistence in some animal or other, but want those organs, veins, and muscles which animals enjoy. And therefore no story delivers that ever any egg was formed immediately from earth; and the poets themselves tell us, that the egg out of which came the Tyndaridae fell down from heaven. But even till this time the earth produceth some perfect and organized animals, as mice in Egypt, and snakes, frogs, and grasshoppers almost everywhere, some external and invigorating principle assisting in the production. And in Sicily, where in the servile war much blood was shed, and many carcasses rotted on the ground, whole swarms of locusts were produced, and spoiled the corn over the whole isle. Such spring from and are nourished by the earth; and seed being formed in them, pleasure and titillation provoke them to mix, upon which some lay eggs, and some bring forth their young alive; and this evidently proves that animals first sprang from earth, and afterwards by copulation, after different ways, propagated their several kinds. In short, it is the same thing as if you said the womb was before the woman; for as the womb is to the egg, the egg is to the chick that is formed in it; so that he that inquires how birds should be when there were no eggs, might ask as well how men and women could be before any organs of generation were formed. Parts generally have their subsistence together with the whole;
