ARISTOTLE'S Ethics are not focused on a group of moral principles; they are developed from the affirmation of an end which subordinates all human activities. This end is sought for itself and is called "the good and the best".

The Aristotelian discussion of this theme has focused the attention of researchers and commentators on the question of practical reason. The main problem has been to determine if the end is fixed by moral virtue alone while practical reason is concerned only with the deliberation on the "means" that contribute to the end, or if practical wisdom plays a role as well in the determination of the end.
