in Thoreau’s Journal:
This seems to be the true hour to be abroad, sauntering far from home. Your thoughts being already turned toward home, your walk in one sense ended, you are in that favorable frame of mind described by De Quincey, open to great impressions, and you see those rare sights with the unconscious side of the eye, which you could not see by a direct gaze before.
Then the dews begin to descend in your mind, and its atmosphere is strained of all impurities. Home is farther away than ever; here is home. The beauty of the world impresses you. There is a coolness in your mind as in a well. Life is too grand for ripples.
