Context: To possess ourselves of a clear idea of what government is, or ought to be, we must trace it to its origin. In doing this we shall easily discover that governments must have arisen either out of the people or over the people. Mr. Burke has made no distinction. He investigates nothing to its source, and therefore he confounds everything; but he has signified his intention of undertaking, at some future opportunity, a comparison between the constitution of England and France. As he thus renders it a subject of controversy by throwing the gauntlet, I take him upon his own ground. It is in high challenges that high truths have the right of appearing; and I accept it with the more readiness because it affords me, at the same time, an opportunity of pursuing the subject with respect to governments arising out of society.
