But we still use the world "vision" to express an awareness of higher purpose. The person who can see wondrous possibilities that have not yet been actualized is called a "visionary." Even our concept of the universe as an evolving, magnificent organism depends on the vision of human beings, extended through the scientific instruments that reveal billions of years of space-time or the intricacies of molecular genetic structures.
