Whether pain or sorrow is assuaged by every pleasure?

Objections

Objection 1 : It would seem that not every pleasure assuages every pain or sorrow. For pleasure does not assuage sorrow, save in so far as it is contrary to it: for "remedies work by contraries" (Ethic. ii, 3). But not every pleasure is contrary to every sorrow; as stated above (Question [35], Article [4]). Therefore not every pleasure assuages every sorrow.
Objection 2 : Further, that which causes sorrow does not assuage it. But some pleasures cause sorrow; since, as stated in Ethic. ix, 4, "the wicked man feels pain at having been pleased." Therefore not every pleasure assuages sorrow.
Objection 3 : Further, Augustine says (Confess. iv, 7) that he fled from his country, where he had been wont to associate with his friend, now dead: "for so should his eyes look for him less, where they were not wont to see him." Hence we may gather that those things which united us to our dead or absent friends, become burdensome to us when we mourn their death or absence. But nothing united us more than the pleasures we enjoyed in common. Therefore these very pleasures become burdensome to us when we mourn. Therefore not every pleasure assuages every sorrow.
