Mass mind
When the ranks of society are unequal, and men unlike each other in condition, there are some individuals invested with all the power of superior intelligence, learning, and enlightenment, whilst the multitude is sunk in ignorance and prejudice. Men living at these aristocratic periods are therefore naturally induced to shape their opinions by the superior standard of a person or a class of persons, whilst they are averse to recognize the infallibility of the mass of the people.
The contrary takes place in ages of equality. The nearer the citizens are drawn to the common level of an equal and similar condition, the less prone does each man become to place implicit faith in a certain man or a certain class of men. But his readiness to believe the multitude increases, and opinion is more than ever mistress of the world. Not only is common opinion the only guide which private judgment retains amongst a democratic people, but amongst such a people it possesses a power infinitely beyond what it has elsewhere. At periods of equality men have no faith in one another, by reason of their common resemblance; but this very resemblance gives them almost unbounded confidence in the judgment of the public; for it would not seem probable, as they are all endowed with equal means of judging, but that the greater truth should go with the greater number.
When the inhabitant of a democratic country compares himself individually with all those about him, he feels with pride that he is the equal of any one of them; but when he comes to survey the totality of his fellows, and to place himself in contrast to so huge a body, he is instantly overwhelmed by the sense of his own insignificance and weakness. The same equality which renders him independent of each of his fellow-citizens taken severally, exposes him alone and unprotected to the influence of the greater number. The public has therefore among a democratic people a singular power, of which aristocratic nations could never so much as conceive an idea; for it does not persuade to certain opinions, but it enforces them, and infuses them into the faculties by a sort of enormous pressure of the minds of all upon the reason of each.
