Thoreau's Journal: 27-Aug-1859

All our life, i.e. the living part of it, is a persistent dreaming awake. The boy does not camp in his father’s yard. That would not be adventurous enough, there are too many sights and sounds to disturb the illusion; so he marches off twenty or thirty miles and there pitches his tent, where stranger inhabitants are tamely sleeping in their beds just like his father at home, and camps in their yard, perchance. But then he dreams uninterruptedly that he is anywhere but where he is.
