"If a society hopes to achieve renewal, it will have to be a hospitable environment for creative men and women. It will also have to produce men and women with the capacity for self-renewal…"
"Most human beings go through their lives only partially aware of the full range of their abilities… Exploration of the full range of his own potentialities is not something that the self-renewing man leaves to the chances of life. It is something he pursues systematically, or at least avidly, to the end of his days. He looks forward to an endless and unpredictable dialogue between his potentialities and the claims of life — not only the claims he encounters but the claims he invents. And by potentialities I mean not just skills, but the full range of his capacities for sensing, wondering, learning, understanding, loving, aspiring."
