Whether concupiscence is infinite?

Objections

Objection 1 : It would seem that concupiscence is not infinite. For the object of concupiscence is good, which has the aspect of an end. But where there is infinity there is no end (Metaph. ii, 2). Therefore concupiscence cannot be infinite.
Objection 2 : Further, concupiscence is of the fitting good, since it proceeds from love. But the infinite is without proportion, and therefore unfitting. Therefore concupiscence cannot be infinite.
Objection 3 : Further, there is no passing through infinite things: and thus there is no reaching an ultimate term in them. But the subject of concupiscence is not delighted until he attain the ultimate term. Therefore, if concupiscence were infinite, no delight would ever ensue.
