Over the mountain, which who stands upon,
Is apt to doubt if it be indeed a road;
While if he views it from the waste itself,
Up goes the line there, plain from base to brow,
Not vague, mistakable! What’s a break or two
Seen from the unbroken desert either side?
And then (to bring in fresh philosophy)
What if the breaks themselves should prove at last
The most consummate of contrivances
To train a man’s eye, teach him what is faith?”
