Whether to enjoy belongs to the rational creature alone, or also to irrational animals?

Objections

Objection 1 : It would seem that to enjoy belongs to men alone. For Augustine says (De Doctr. Christ. i, 22) that "it is given to us men to enjoy and to use." Therefore other animals cannot enjoy.
Objection 2 : Further, to enjoy relates to the last end. But irrational animals cannot obtain the last end. Therefore it is not for them to enjoy.
Objection 3 : Further, just as the sensitive appetite is beneath the intellectual appetite, so is the natural appetite beneath the sensitive. If, therefore, to enjoy belongs to the sensitive appetite, it seems that for the same reason it can belong to the natural appetite. But this is evidently false, since the latter cannot delight in anything. Therefore the sensitive appetite cannot enjoy: and accordingly enjoyment is not possible for irrational animals.
