This question has been on my mind since reading Daniel Quinn's Beyond Civilization almost a decade ago. I know there are visions in mission statements and personal visions and so on, but I don't think I've fully grasped what vision means. Here is the excerpt out of BC that I keep going back to when I think about vision:
Vision is like Gravity
Vision is to culture what gravity is to matter. When you see a ball roll off a table and fall to the floor, you should think, "Gravity is at work here." When you see a culture make its appearance and spread outward in all directions until it takes over the entire world, you should think, "Vision is at work here."
When you see a small group of people begin behaving in a special way that subsequently spreads across an entire continent, you should think, "Vision is at work here." If I tell you that the small group I have in mind were followers of a first-century preacher named Paul and that the continent was Europe, you'll know the vision was Christianity.
Dozens or perhaps even hundreds of books have investigated the reasons for Christianity's success, but not one of them was written before the nineteenth century. Before that nineteenth century it seemed to everyone that Christianity no more needed reasons to succeed than gravity does. It was bound to succeed. Its success was sponsored by destiny.
For exactly the same reason, no one has ever written a book investigating the reasons for the success of the Industrial Revolution. It's perfectly obvious to us that the Industrial Revolution was bound to succeed. It could no more have failed than a ball rolling off a table could fall toward the ceiling.
That's the power of vision.
I'm looking for personal definitions of vision or what other authors have said about vision. Any help would be appreciated.
