Final answer:
Aristotle believes human good turns out to be the activity of the soul in accord with Rationality.
Step-by-step explanation:
Aristotle believes human good turns out to be the activity of the soul in accord with Rationality. Aristotle identifies rationality as the unique function of human beings, and human virtue or excellence is therefore realized through the development or perfection of reason. To exercise or possess virtue is to demonstrate excellent character. Someone with a virtuous character is consistent, firm, self-controlled, and well-off.
