In this matter we shall consider first the last end of human life; and secondly, those things by means of which man may advance towards this end, or stray from the path: for the end is the rule of whatever is ordained to the end.
And since the last end of human life is stated to be happiness, we must consider (1) the last end in general; (2) happiness.
Under the first head there are eight points of inquiry:
A Whether it belongs to man to act for an end?
A Whether this is proper to the rational nature?
A Whether a man's actions are specified by their end?
A Whether there is any last end of human life?
A Whether one man can have several last ends?
A Whether man ordains all to the last end?
A Whether all men have the same last end?
A Whether all other creatures concur with man in that last end?
