This dissertation provides a thorough examination of the role of aeschyn (as distinct from aids) in Aristotle's conception of human nature by illuminating the political and ethical implications of shame and shamelessness and the effect of these implications in his treatises. It is crucial, both to one's own personhood and eudaimonia as well as to the existence of a just and balanced state, that aeschyn be understood and respected because of the self-evaluating ability that it maintains. The aim of this work is to show that a recognition and appreciation of aeschyn as understood in Aristotle's conception of human nature simultaneously leads to eudaimonia and away from the dangerous state of anaeschyntia (shamelessness). Aeschyn is required in order to create a better existence both on the personal level and on the larger level of social community. The function and responsibility of aeschyn in Aristotle's work is recognized in its full potential as a civic virtue: specifically, metriopatheia.
