“Thoreau got up each morning and walked to the woods as though he had never been where he was going to, so that whatever was there came to him like liquid into an empty glass. Many people taking such a walk would have their heads so full of other ideas that it would be a long time before they were capable of hearing or seeing. Most people are blinded by themselves.”
