Whether pain and sorrow are assuaged by the contemplation of truth?

Objections

Objection 1 : It would seem that the contemplation of truth does not assuage sorrow. For it is written (Eccles. 1:18): "He that addeth knowledge addeth also sorrow" [Vulg.: 'labor']. But knowledge pertains to the contemplation of truth. Therefore the contemplation of truth does not assuage sorrow.
Objection 2 : Further, the contemplation of truth belongs to the speculative intellect. But "the speculative intellect is not a principle of movement"; as stated in De Anima iii, 11. Therefore, since joy and sorrow are movements of the soul, it seems that the contemplation of truth does not help to assuage sorrow.
Objection 3 : Further, the remedy for an ailment should be applied to the part which ails. But contemplation of truth is in the intellect. Therefore it does not assuage bodily pain, which is in the senses.
