Democracy in America, Volume 3 by Alexis de Tocqueville

We perceive that for several ages social conditions have tended to equality, and we discover that in the course of the same period the manners of society have been softened. Are these two things merely contemporaneous, or does any secret link exist between them, so that the one cannot go on without making the other advance? Several causes may concur to render the manners of a people less rude; but, of all these causes, the most powerful appears to me to be the equality of conditions. Equality of conditions and growing civility in manners are, then, in my eyes, not only contemporaneous occurrences, but correlative facts. When the fabulists seek to interest us in the actions of beasts, they invest them with human notions and passions; the poets who sing of spirits and angels do the same; there is no wretchedness so deep, nor any happiness so pure, as to fill the human mind and touch the heart, unless we are ourselves held up to our own eyes under other features.

This is strictly applicable to the subject upon which we are at present engaged. When all men are irrevocably marshalled in an aristocratic community, according to their professions, their property, and their birth, the members of each class, considering themselves as children of the same family, cherish a constant and lively sympathy towards each other, which can never be felt in an equal degree by the citizens of a democracy. But the same feeling does not exist between the several classes towards each other. Amongst an aristocratic people each caste has its own opinions, feelings, rights, manners, and modes of living. Thus the men of whom each caste is composed do not resemble the mass of their fellow-citizens; they do not think or feel in the same manner, and they scarcely believe that they belong to the same human race. They cannot, therefore, thoroughly understand what others feel, nor judge of others by themselves.
