It is the Course of Human Progress, and the important elements that were successively added as each leading phase of civilization appeared, that is endeavored to be traced in the Historical Review of the First Part of this book. While following the general march of events chronologically, we have stopped here and there to take a general survey, in order the better to understand the significance of detached facts, or to examine a new influence that enters among the forces moulding the future. Our space did not allow an exhaustive process; nor was it desirable. We have taken note of only the more important landmarks of Progress. Too much detail would confuse the mind by engaging it in an intricate mass of facts. It is the _thread_ of events, that joins the nations and ages together, or the _channel_ by which they sent down to our day—from Asia to Europe, and from Europe to America—each their special contribution to the political wisdom and the free institutions of America, that we have endeavored to find. We hope we have not underrated any people or any time, and that we have not _overrated_ the value and glory of America. America is yet young. Its founders, the authors of its Constitution, were unaware of the singular excellence and nobility of their work. Like all other people, they built according to their genius and instincts. Time only could show whether they built for immortality. They feared and trembled over their work; but Time has set on it his seal of approval. Our people are busy using their liberties and energies, each for his individual benefit, as is quite right and proper; since the welfare of individuals makes the prosperity of the community. But a government left to take care of itself is prone to do that work only too well. We have done well and wisely in important crises; but a more intelligent and constant watchfulness over the ordinary course of public affairs would have been still better. It is plain that the general mind among us has grown clearer and more accurate in its judgments as experience has accumulated, for the original direction toward popular freedom has not changed. Various incongruities have been laid aside and oversights corrected, the severe strain of civil war and an unheard of rapidity of growth have not shaken, but more clearly revealed the strength and unity of the nation. Yet, more intelligence and more care would have saved us many shocks and made our success more pronounced and more brilliant. “Knowledge is power,” when wisely applied; and a more accurate acquaintance with their government and its history will enable American Citizens to mould it more wisely still, to correct all defects of administration, and to speedily reach that minimum of governmental interference with the efforts and interests of the citizens which shall give them the fullest liberty consistent with security and surrender the whole round of human life, as completely as possible, to the beneficent action of natural law.
