The Nicomachean Ethics

  In Book I of the Nicomachean Ethics, Aristotle considers what the human good could be. What does he ultimately argue is the good for humans? What is it called, and what, in more detail, is it? What is his argument (or arguments), and how does it (or do they) invoke the concept of functioning? Do you think his arguments are correct? Is there any interpretation on which his arguments work? Why or why not?
