Christopher Photography / Technogeekchris Gadget Corner - Aristotle taught that to achieve the good life, one must live a balanced life and avoid excess. An eye is only a good eye in so much as it can see - that man must have a function uncommon to anything else, and that this function must be an activity of the soul. Aristotle identified the best activity of the soul as eudaimonia: a happiness or joy that pervades the good life.
