Whether in the state of innocence generation existed?

Objections

Objection 1 : It would seem there would have been no generation in the state of innocence. For, as stated in Phys. v, 5, "corruption is contrary to generation." But contraries affect the same subject: also there would have been no corruption in the state of innocence. Therefore neither would there have been generation.
Objection 2 : Further, the object of generation is the preservation in the species of that which is corruptible in the individual. Wherefore there is no generation in those individual things which last for ever. But in the state of innocence man would have lived for ever. Therefore in the state of innocence there would have been no generation.
Objection 3 : Further, by generation man is multiplied. But the multiplication of masters requires the division of property, to avoid confusion of mastership. Therefore, since man was made master of the animals, it would have been necessary to make a division of rights when the human race increased by generation. This is against the natural law, according to which all things are in common, as Isidore says (Etym. v, 4). Therefore there would have been no generation in the state of innocence.
