The manners of the Americans of the United States are, then, the real cause which renders that people the only one of the American nations that is able to support a democratic government; and it is the influence of manners which produces the different degrees of order and of prosperity that may be distinguished in the several Anglo-American democracies. Thus the effect which the geographical position of a country may have upon the duration of democratic institutions is exaggerated in Europe. Too much importance is attributed to legislation, too little to manners. These three great causes serve, no doubt, to regulate and direct the American democracy; but if they were to be classed in their proper order, I should say that the physical circumstances are less efficient than the laws, and the laws very subordinate to the manners of the people. I am convinced that the most advantageous situation and the best possible laws cannot maintain a constitution in spite of the manners of a country; whilst the latter may turn the most unfavorable positions and the worst laws to some advantage. The importance of manners is a common truth to which study and experience incessantly direct our attention. It may be regarded as a central point in the range of human observation, and the common termination of all inquiry. So seriously do I insist upon this head, that if I have hitherto failed in making the reader feel the important influence which I attribute to the practical experience, the habits, the opinions, in short, to the manners of the Americans, upon the maintenance of their institutions, I have failed in the principal object of my work. （二）
For my part, I am continually astonished that a mark so simple is not recognized, or that men are of so bad faith as not to admit it. What is the end of political association? The preservation and prosperity of its members. And what is the surest mark of their preservation and prosperity? Their numbers and population. Seek then nowhere else this mark that is in dispute. The rest being equal, the government under which, without external aids, without naturalization or colonies, the citizens increase and multiply most, is beyond question the best. The government under which a people wanes and diminishes is the worst. Calculators, it is left for you to count, to measure, to compare.
As the particular will acts constantly in opposition to the general will, the government continually exerts itself against the Sovereignty. The greater this exertion becomes, the more the constitution changes; and, as there is in this case no other corporate will to create an equilibrium by resisting the will of the prince, sooner or later the prince must inevitably suppress the Sovereign and break the social treaty. This is the unavoidable and inherent defect which, from the very birth of the body politic, tends ceaselessly to destroy it, as age and death end by destroying the human body. There are two general courses by which government degenerates: i.e., when it
