A first small step into the Nicoamchean Ethics, with an eye on St. Thomas
Aquinas...

"EVERY art (technê) and every inquiry (methodos), and similarly every action
(praxis) and pursuit (proairesis) , is thought to (dokei) aim at some good;
and for this reason the good has rightly been declared to be that at which
all things aim (ephiethai)." (Ross)

Alternative translations:
-technê: craft (Irwin), expert knowledge (Rowe), skill (Annas)
-methodos: line of inquiry (Irwin), discipline scientifique (Gauthier &
Jolif)
-proairesis: decision (Irwin), choice (Annas), intention morale (G&J)
-dokei: seems to (Irwin), de l'aveu de tous [as all admit] (G&J) [Sarah
Broadie agrees with G&J: "Aristotle invokes received views. The 'seems to'
does not indicated doubt on his part."]
-ephiesthai: seek (Irwin, Rowe)

"...every practical pursuit or undertaking, seems to aim at some good."
Aquinas comments:
"There is no problem from the fact that some men desire evil. For they
desire evil only under the aspect of good, that is, insofar as they think it
good. Hence their intention primarily aims at the good and only incidentally
touches on the evil. (Litzinger)

"...the good...at which *all* things aim."
Aquinas:
"Therefore he does not single out here a particular good but rather
discusses good in general. However, because nothing is good except insofar
as it is a likeness and participation of the highest good, the highest good
itself is in some way desired in every particular good. Thus it can be said
that the true good is what all desire."

Aquinas is clear here about the fact that Aristotle is not at all seeing the
good as a Form like in Plato's Republic or the Philebus, but as a goal, "a
movement of appetite." (Cf. Aristotle's "seek", "aim")
