Book 1
7.9
And the end is a greater good than the means; for the latter is desirable for the sake of something else, the former for its own sake; for instance, exercise is only a means for the acquirement of a good constitution.
7.10
And that which has less need of one or several other things in addition is a greater good, for it is more independent (and having less need means needing fewer or easier additions).
7.11
And when one thing does not exist or cannot be brought into existence without the aid of another, but that other can, then that which needs no aid is more independent, and accordingly is seen to be a greater good.
7.12
And if one thing is a first principle, and another not; if one thing is a cause and another not, for the same reason; for without cause or first principle nothing can exist or come into existence. And if there are two first principles or two causes, that which results from the greater is greater; and conversely, when there are two first principles or two causes, that which is the first cause or principle of the greater is greater.
