Whether all sorrow is contrary to all pleasure?

❌ Objection 1 : It would seem that all sorrow is contrary to all pleasure. Because, just as whiteness and blackness are contrary species of color, so pleasure and sorrow are contrary species of the soul's passions. But whiteness and blackness are universally contrary to one another. Therefore pleasure and sorrow are so too.

❌ Objection 2 : Further, remedies are made of things contrary (to the evil). But every pleasure is a remedy for all manner of sorrow, as the Philosopher declares (Ethic. vii, 14). Therefore every pleasure is contrary to every sorrow.

❌ Objection 3 : Further, contraries are hindrances to one another. But every sorrow hinders any kind of pleasure: as is evident from Ethic. x, 5. Therefore every sorrow is contrary to every pleasure.
