Book 5
Chapter XIX. OF THE GENERATION OF ANIMALS, HOW ANIMALS ARE BEGOTTEN, AND WHETHER THEY ARE OBNOXIOUS TO CORRUPTION.
19
THOSE philosophers who entertain the opinion that the world had an original do likewise assert that all animals are generated and corruptible. The followers of Epicurus, who gives an eternity to the world, affirm the generation of animals ariseth from the various permutation of parts mutually among themselves, for they are parts of this world. With them Anaxagoras and Euripides concur: For nothing dies, But different changes give their various forms.
