Democracy is no easy form of government. Few nations have been able to sustain it. For it requires that we take the chances of freedom; that the liberating play of reason be brought to bear on events filled with passion; that dissent be allowed to make its appeal for acceptance; that men chance error in their search for the truth.

The essential humanity of men can be protected and preserved only where government must answer, not just to the wealthy, not just to those of a particular religion, or a particular race, but to all its people.

At the heart of that western freedom and democracy is the belief that the individual man...is the touchstone of value, and all society, all groups, and states, exist for that person's benefit. Therefore the enlargement of liberty for individual human beings must be the supreme goal and the abiding practice of any western society.

Each nation has different obstacles and different goals, shaped by the vagaries of history and of experience. Yet as I talk to young people around the world I am impressed not by the diversity but by the closeness of their goals, their desires and their concerns and their hope for the future.
