How did thoreaus night in jail change his perspective

Thoreau now turns to his personal experiences with civil disobedience. He says that he hasn't paid a poll tax for six years and that he spent a night in jail once because of this. His experience in jail did not hurt his spirit: "I saw that, if there was a wall of stone between me and my townsmen, there was a still more difficult one to break through, before they could get to be as free as I was." Since the State couldn't reach his essential self, they decided to punish his body. This illustrated the State's ultimate weakness, and Thoreau says that he came to pity the State. The masses can't force him to do anything; he is subject only to those who obey a higher law. He says that he has to obey his own laws and try to flourish in this way.

The night in prison, he recounts, was "novel and interesting enough." His roommate had been accused of burning down a barn, though Thoreau speculated that the man had fallen asleep drunk in the barn while smoking a pipe. Thoreau was let in on the gossip and history of the jail and was shown several verses that were composed in the jail. The workings of the jail fascinated him, and staying in jail that night was like traveling in another country. He felt as if he was seeing his town through the light of the middle ages--as if he had never heard the sounds of his town before. After the first night, however, somebody interfered and paid his tax, and so he was released from prison the next day. Upon Thoreau's release, it seemed some kind of change had come over the town, the State and the country. He realized that the people he lived with were only friends in the good times. They were not interested in justice or in taking any risks. He soon left the town and was out of view of the State again.
