Whether sorrow or pain weakens all activity?

❌ Objection 1 : It would seem that sorrow does not weaken all activity. Because carefulness is caused by sorrow, as is clear from the passage of the Apostle quoted above (Article [2], Objection [1]). But carefulness conduces to good work: wherefore the Apostle says (2 Tim. 2:15): "Carefully study to present thyself . . . a workman that needeth not to be ashamed." Therefore sorrow is not a hindrance to work, but helps one to work well.

❌ Objection 2 : Further, sorrow causes desire in many cases, as stated in Ethic. vii, 14. But desire causes intensity of action. Therefore sorrow does too.

❌ Objection 3 : Further, as some actions are proper to the joyful, so are others proper to the sorrowful; for instance, to mourn. Now a thing is improved by that which is suitable to it. Therefore certain actions are not hindered but improved by reason of sorrow.
