What is the human good?
Accordingly, what is the human good according to Aristotle?
In his ethical works, Aristotle describes eudaimonia as the highest human good. In Book I of the Nicomachean Ethics he goes on to identify eudaimonia as the excellent exercise of the intellect, leaving it open whether he means practical activity or intellectual activity.
Correspondingly, what is the function of a person?
In Nicomachean Ethics 1.7, Aristotle claims that to discover the human good we must identify the function of a human being. He argues that the human function is rational activity. Our good is therefore rational activity performed well, which Aristotle takes to mean in accordance with virtue.
The term was used in medieval philosophy. In the Thomist synthesis of Aristotelianism and Christianity, the highest good is usually defined as the life of the righteous and/or the life led in communion with God and according to God's precepts.
