The observations I have here made on events may also be applied in part to opinions. Two things are surprising in the United States--the mutability of the greater part of human actions, and the singular stability of certain principles. Men are in constant motion; the mind of man appears almost unmoved. When once an opinion has spread over the country and struck root there, it would seem that no power on earth is strong enough to eradicate it. In the United States, general principles in religion, philosophy, morality, and even politics, do not vary, or at least are only modified by a hidden and often an imperceptible process: even the grossest prejudices are obliterated with incredible slowness, amidst the continual friction of men and things. I hear it said that it is in the nature and the habits of democracies to be constantly changing their opinions and feelings. This may be true of small democratic nations, like those of the ancient world, in which the whole community could be assembled in a public place and then excited at will by an orator. But I saw nothing of the kind amongst the great democratic people which dwells upon the opposite shores of the Atlantic Ocean. What struck me in the United States was the difficulty in shaking the majority in an opinion once conceived, or of drawing it off from a leader once adopted. Neither speaking nor writing can accomplish it; nothing but experience will avail, and even experience must be repeated. This is surprising at first sight, but a more attentive investigation explains the fact. I do not think that it is as easy as is supposed to uproot the prejudices of a democratic people--to change its belief--to supersede principles once established, by new principles in religion, politics, and morals--in a word, to make great and frequent changes in men's minds. Not that the human mind is there at rest--it is in constant agitation; but it is engaged in infinitely varying the consequences of known principles, and in seeking for new consequences, rather than in seeking for new principles. Its motion is one of rapid circumvolution, rather than of straightforward impulse by rapid and direct effort; it extends its orbit by small continual and hasty movements, but it does not suddenly alter its position.
