Whether one pleasure can be contrary to another?

❌ Objection 1 : It would seem that one pleasure cannot be contrary to another. Because the passions of the soul derive their species and contrariety from their objects. Now the object of pleasure is the good. Since therefore good is not contrary to good, but "good is contrary to evil, and evil to good," as stated in Praedic. viii; it seems that one pleasure is not contrary to another.

❌ Objection 2 : Further, to one thing there is one contrary, as is proved in Metaph. x, 4. But sadness is contrary to pleasure. Therefore pleasure is not contrary to pleasure.

❌ Objection 3 : Further, if one pleasure is contrary to another, this is only on account of the contrariety of the things which give pleasure. But this difference is material: whereas contrariety is a difference of form, as stated in Metaph. x, 4. Therefore there is no contrariety between one pleasure and another.
