The golden mean or golden middle way is the desirable middle between two extremes, one of excess and the other of deficiency. It appeared in Greek thought at least as early as the Delphic maxim “nothing in excess”, which was discussed in Plato’s Philebus. Aristotle analyzed the golden mean in the Nicomachean Ethics Book II: That virtues of character can be described as means. It was subsequently emphasized in Aristotelian virtue ethics.[1] For example, in the Aristotelian view, courage is a virtue, but if taken to excess would manifest as recklessness, and, in deficiency, cowardice.
