Let us plant dates even though those who plant them will never eat them. We must live by the love of what we will never see. This is the secret discipline. It is a refusal to let the creative act be dissolved away in immediate sense experience, and a stubborn commitment to the future of our grandchildren. Such disciplined love is what has given prophets, revolutionaries, and saints the courage to die for the future they envisaged. They make their own bodies the seed of their highest hope.
