“You can never cross the ocean until you have the courage to lose sight of the shore”

A Prescription for Hope (1985)
Context: If we are to succeed, this vision must possess millions of people. We must convince each generation that they are but transient passengers on this planet earth. It does not belong to them. They are not free to doom generations yet unborn. They are not at liberty to erase humanity's past nor dim its future. Only life itself can lay claim to sacred continuity. The magnitude of the danger and its imminence must bring the human family together in common pursuit of peace denied throughout the century. On the threshold of a new millennium the achievement of world peace is no longer remote, for it is beckoned by the unleashing of the deepest spiritual forces embedded in humankind when threatened with extinction. The reason, the creativeness, and the courage that human beings possess foster an abiding faith that what humanity creates, humanity can and will control.
