The world is very different now. For man holds in his mortal hands the power to abolish all forms of human poverty, and all forms of human life.

The stories of past courage... can offer hope, they can provide inspiration. But they cannot supply courage itself. For this each man must look into his own soul.

Aeschylus and Plato are remembered today long after the triumphs of Imperial Athens are gone. Dante outlived the ambitions of thirteenth century Florence.

Those who dare to fail miserably can achieve greatly.
