We must now consider delight and sadness.
Concerning delight four things must be considered: (1) Delight in itself; (2) The causes of delight; (3) Its effects; (4) Its goodness and malice.
Under the first head there are eight points of inquiry:
A Whether delight is a passion?
A Whether delight is subject to time?
A Whether it differs from joy?
A Whether it is in the intellectual appetite?
A Of the delights of the higher appetite compared with the delight of the lower;
A Of sensible delights compared with one another;
A Whether any delight is non-natural?
A Whether one delight can be contrary to another?
