A quote
“What, then,” comes the retort, “if good health, rest, and freedom from pain are not likely to hinder virtue, shall you not seek all these?” Of course I shall seek them, but not because they are goods,—I shall seek them because they are according to nature and because they will be acquired through the exercise of good judgment on my part. What, then, will be good in them? This alone,—that it is a good thing to choose them. For when I don suitable attire, or walk as I should, or dine as I ought to dine, it is not my dinner, or my walk, or my dress that are goods, but the deliberate choice which I show in regard to them, as I observe, in each thing I do, a mean that conforms with reason.
