Prologue A[1] A[2] A[3] A[4]
We must now consider the causes of sorrow: under which head there are four points of inquiry:
A[1] Whether sorrow is caused by the loss of a good or rather by the presence of an evil?
A[2] Whether desire is a cause of sorrow?
A[3] Whether the craving for unity is a cause of sorrow?
A[4] Whether an irresistible power is a cause of sorrow?
