What is the supreme good for Aristotle?
Political Science has for its object the Supreme Good But such is manifestly the science of Politics; for it is this that ordains which of the sciences are to exist in states, and what branches of knowledge the different classes of the citizens are to learn, and up to what point . . . Therefore, the Good of man must be the end of the science of Politics. For even though it be the case that the Good is the same for the individual and for the state, nevertheless, the good of the state is manifestly greater and more perfect good . . To secure the good of one person only is better than nothing; but to secure the good of anation or a state is a nobler and more divine achievement.
p.s. Aristotle was neither obese nor an atheist.
