Property in the sense of a bare livelihood seems to be given by nature herself to all, both when they are first born and when they are grown up. For some animals bring forth, together with their offspring, so much food as will last until they are able to supply themselves. In like manner we may infer that, after the birth of animals, plants exist for their sake, and that the other animals exist for the sake of man.
