Whether expansion is an effect of pleasure?

Objections

Objection 1 : It would seem that expansion is not an effect of pleasure. For expansion seems to pertain more to love, according to the Apostle (2 Cor. 6:11): "Our heart is enlarged." Wherefore it is written (Ps. 118:96) concerning the precept of charity: "Thy commandment is exceeding broad." But pleasure is a distinct passion from love. Therefore expansion is not an effect of pleasure.
Objection 2 : Further, when a thing expands it is enabled to receive more. But receiving pertains to desire, which is for something not yet possessed. Therefore expansion seems to belong to desire rather than to pleasure.
Objection 3 : Further, contraction is contrary to expansion. But contraction seems to belong to pleasure, for the hand closes on that which we wish to grasp firmly: and such is the affection of appetite in regard to that which pleases it. Therefore expansion does not pertain to pleasure.
