Time, events, or the unaided individual action of the mind, will sometimes undermine or destroy an opinion, without any outward sign of the change. It has not been openly assailed, no conspiracy has been formed to make war on it, but its followers one by one noiselessly secede--day by day a few of them abandon it, until last it is only professed by a minority. In this state it will still continue to prevail. As its enemies remain mute, or only interchange their thoughts by stealth, they are themselves unaware for a long period that a great revolution has actually been effected; and in this state of uncertainly they take no steps--they observe each other and are silent. The majority have ceased to believe what they believed before; but they still affect to believe, and this empty phantom of public opinion in strong enough to chill innovators, and to keep them silent and at respectful distance. We live at a time which has witnessed the most rapid changes of opinion in the minds of men; nevertheless it may be that the leading opinions of society will ere long be more settled than they have been for several centuries in our history: that time is not yet come, but it may perhaps be approaching. As I examine more closely the natural wants and tendencies of democratic nations, I grow persuaded that if ever social equality is generally and permanently established in the world, great intellectual and political revolutions will become more difficult and less frequent than is supposed. Because the men of democracies appear always excited, uncertain, eager, changeable in their wills and in their positions, it is imagined that they are suddenly to abrogate their laws, to adopt new opinions, and to assume new manners. But if the principle of equality predisposes men to change, it also suggests to them certain interests and tastes which cannot be satisfied without a settled order of things; equality urges them on, but at the same time it holds them back; it spurs them, but fastens them to earth;--it kindles their desires, but limits their powers. This, however, is not perceived at first; the passions which tend to sever the citizens of a democracy are obvious enough; but the hidden force which restrains and unites them is not discernible at a glance.
