“1:29, 30) : "Behold I have given you every herb.. . and all trees .. . to be your meat, and to all beasts of the earth": and again (Gen. 9:3) : "Everything that moveth and liveth shall be meat to you."
Reply Obj. 1: According to the Divine ordinance the life of animals and plants is preserved not for themselves but for man. Hence, as Augustine says (De Civ. Dei i, 20) , "by a most just ordinance of the Creator, both their life and their death are subject to our use."
Reply Obj. 2: Dumb animals and plants are devoid of the life of reason whereby to set themselves in motion; they are moved, as it were by another, by a kind of natural impulse, a sign of which is that they are naturally enslaved and accommodated to the uses of others.
