One should next consider pleasure and sorrow. About pleasure, four points should be considered: first, pleasure in itself; second, the causes of pleasure; third, its effects; fourth, its goodness and evilness. About the first point, eight queries are raised. (1) Whether pleasure is a passion. (2) Whether it exists in time. (3) Whether it differs from joy. (4) Whether it is in the intellectual appetite. (5) On a comparison of pleasures of the higher appetite to the pleasure of the lower appetite. (6) On a comparison of sensible pleasures to one another. (7) Whether any pleasure is non-natural. (8) Whether pleasure can be contrary to pleasure.
