in Thoreau’s Journal:

Men lie behind the barrier of a relation as effectually concealed as the landscape by a mist; and when at length some unforeseen accident throws me into a new attitude toward them, I am astounded, as if for the first time I saw the sun on the hill-side.—  They lie out before me like a new order of things.— As when the master meets his pupil as a man.— Then first do we stand under the same heavens—and master and pupil alike go down the resistless ocean stream together.
