14. (19) As for the souls of the other living beings, fallen to the degree of entering brute bodies, these too must be immortal. And if there is in the animal world any other phase of soul, its only possible origin, since it is the life-giver, is, still, that one principle of life: so too with the soul in the vegetal order.
All have sprung from one source, all have life as their own, all are incorporeal, indivisible, all are real-beings.
If we are told that man's soul being tripartite must as a compound entity be dissolved, our answer shall be that pure souls upon their emancipation will put away all that has fastened to them at birth, all that increment which the others will long retain.
But even that inferior phase thus laid aside will not be destroyed as long as its source continues to exist, for nothing from the realm of real being shall pass away.
