We have now to consider (1) what happiness is, and (2) what things are required for it.

Concerning the first there are eight points of inquiry:

A1 Whether happiness is something uncreated?

A2 If it be something created, whether it is an operation?

A3 Whether it is an operation of the sensitive, or only of the intellectual part?

A4 If it be an operation of the intellectual part, whether it is an operation of the intellect, or of the will?

A5 If it be an operation of the intellect, whether it is an operation of the speculative or of the practical intellect?

A6 If it be an operation of the speculative intellect, whether it consists in the consideration of speculative sciences?

A7 Whether it consists in the consideration of separate substances viz. angels?

A8 Whether it consists in the sole contemplation of God seen in His Essence?
