Cathedral thinkers.

"Cathedrals inspire. It's not only their grandeur or splendor, bur the thought that they often took more tha fify years to build. Those who designed them, those who firt worked on them, knew for certain that they would never see them finished. They knew only that they were creating something glorious which would stand for centuries, long after their own names had been forgotten. They had their own dream of sublime and of immortality. We may not need any more cathedrals but we do need cathedral thinkers, people who can think beyond their own lifeties"
