Brief Explanations:

In Civil Disobedience, Thoreau's first thought upon imprisonment was that the prison was a foolish institution. He saw it as a symbol of the state's unjust power and control. He was more concerned with the moral and philosophical implications of his imprisonment rather than practical matters like how long he would be there or getting out quickly. He also did not wonder why he was put behind bars in the sense of being confused about the reason (he knew it was related to his act of civil disobedience against the unjust laws, such as not paying taxes for a war he opposed).

Answer:

He considers the prison a foolish institution.
