Whether sadness causes pleasure?

❌ Objection 1 : It would seem that sadness does not cause pleasure. For nothing causes its own contrary. But sadness is contrary to pleasure. Therefore it does not cause it.

❌ Objection 2 : Further, contraries have contrary effects. But pleasures, when called to mind, cause pleasure. Therefore sad things, when remembered, cause sorrow and not pleasure.

❌ Objection 3 : Further, as sadness is to pleasure, so is hatred to love. But hatred does not cause love, but rather the other way about, as stated above (Question [29], Article [2]). Therefore sadness does not cause pleasure.
