Thomas Aquinas

“ To enjoy implies the absolute movement of the appetite to the appetible: whereas to use implies a movement of the appetite to something as directed to something else. If therefore we compare use and enjoyment in respect of their objects, enjoyment is better than use; because that which is appetible absolutely is better than that which is appetible only as directed to something else. But if we compare them in respect of the apprehensive power that precedes them, greater excellence is required on the part of use: because to direct one thing to another is an act of reason ”

“ But operation belongs to the executive power; and the act of the will does not follow the act of the executive power, on the contrary execution comes last. Therefore use is not an act of the will.
Objection 3: Further, Augustine says (QQ. 83, qu. 30) : "All things that were made were made for man's use, because reason with which man is endowed uses all things by its judgment of them." But judgment of things created by God belongs to the speculative reason; which seems to be altogether distinct from the will, which is the principle of human acts. Therefore use is not an act of the will. ”

“ But in regard to the individual, the obtaining of money is the last end; for the miser would not seek for money, save that he might have it. Therefore, simply and properly speaking, a man enjoys money, because he places his last end therein; but in so far as he seeks to possess it, he is said to use it.
Reply to Objection 1: Augustine is speaking of use in general, in so far as it implies the relation of an end to the enjoyment which a man seeks in that end.
Reply to Objection 2: The end is applied to the purpose of the will, that the will may find rest in it. ”
