And of this nature Happiness is mostly thought to be, for this we choose always for its own sake, and never with a view to anything further: whereas honour, pleasure, intellect, in fact every excellence we choose for their own sakes, it is true (because we would choose each of these even if no result were to follow), but we choose them also with a view to happiness, conceiving that through their instrumentality we shall be happy: but no man chooses happiness with a view to them, nor in fact with a view to any other thing whatsoever.
The same result15 is seen to follow also from the notion of self-sufficiency, a quality thought to belong to the final good. Now by sufficient for Self, we mean not for a single individual living a solitary life, but for his parents also and children and wife, and, in general, friends and countrymen; for man is by nature adapted to a social existence. But of these, of course, some limit must be fixed: for if one extends it to parents and descendants and friends’ friends, there is no end to it. This point, however, must be left for future investigation: for the present we define that to be self-sufficient “which taken alone makes life choice-worthy, and to be in want of nothing;” now of such kind we think Happiness to be: and further, to be most choice-worthy of all things; not being reckoned with any other thing,16 for if it were so reckoned, it is plain we must then allow it, with the addition of ever so small a good, to be more choice-worthy than it was before:17 because what is put to it becomes an addition of so much more good, and of goods the greater is ever the more choice-worthy.
So then Happiness is manifestly something final and self-sufficient, being the end of all things which are and may be done.

But, it may be, to call Happiness the Chief Good is a mere truism, and what is wanted is some clearer account of its real nature. Now this object
