Question 36 — Of the Causes of Sorrow or Pain

We must now consider the causes of sorrow: under which head there are four points of inquiry:

(1) Whether sorrow is caused by the loss of a good or rather by the presence of an evil?

• (2) Whether desire is a cause of sorrow?
• (3) Whether the craving for unity is a cause of sorrow?
• (4) Whether an irresistible power is a cause of sorrow?
