 Paideia was inseparable from another Greek concept: arete or excellence, especially excellence of reputation but also goodness and excellence in all aspects of life. Together paideia and arête form one process of self-development, which is nothing other than civic-development. Thus one could only develop himself in politics, through participation in the activities of the polis; and as individuals developed the characteristics of virtue, so would the polis itself become more virtuous and excellent.
