Master: You have understood it quite well. But what follows?
If the present discussion had no other result but that, it would be sufficient, for it contains in itself the concept of the universal action and the passivity that are the ultimate end of wisdom.
Master: You have understood well what I have said in realizing that the inferior substances are submissive to the superior substances. Know too that this is the path that leads to perfect happiness and that allows us to obtain true delight, that is our end.
Pupil: You have just proved to me in this third book the existence of the intelligible substances, that no one but you has been able to demonstrate. I have acquired the knowledge of these substances, that nobody but myself acquires, according to my ability, and I have thus begun the study of this question. But let us consider in the fourth book matter and form, since that is our object, and demonstrate your previous thesis, namely, that there are matter and form in the intelligibles as in the sensibles.
