It is singular to look round upon a country where the dreams of sages, smiled at as utopian, seem distinctly realized, a people voluntarily submitting to laws of their own imposing, with arms in their hands respecting the voice of a government which their breath created and which their breath could in a moment destroy!

Knowledge signifies things known. Where there are no things known, there is no knowledge. Where there are no things to be known, there can be no knowledge. We have observed that every science, that is, every branch of knowledge, is compounded of certain facts, of which our sensations furnish the evidence. Where no such evidence is supplied, we are without data; we are without first premises; and when, without these, we attempt to build up a science, we do as those who raise edifices without foundations. And what do such builders construct? Castles in the air.
