"In a passage already quoted from Wilhelm von Humboldt, he points out two things as necessary conditions of human development, because necessary to render people unlike one another; namely, freedom, and variety of situations. The second of these two conditions is in this country every day diminishing. The circumstances which surround different classes and individuals, and shape their characters, are daily becoming more assimilated. Formerly, different ranks, different neighbourhoods, different trades and professions, lived in what might be called different worlds; at present, to a great degree in the same. Comparatively speaking, they now read the same things, listen to the same things, see the same things, go to the same places, have their hopes and fears directed to the same objects, have the same rights and liberties, and the same means of asserting them. Great as are the differences of position which remain, they are nothing to those which have ceased. And the assimilation is still proceeding. All the political changes of the age promote it, since they all tend to raise the low and to lower the high. Every extension of education promotes it, because education brings people under common influences, and gives them access to the general stock of facts and sentiments. Improvements in the means of communication promote it, by bringing the inhabitants of distant places into personal contact, and keeping up a rapid flow of changes of residence between one place and another. The increase of commerce and manufactures promotes it, by diffusing more widely the advantages of easy circumstances, and opening all objects of ambition, even the highest, to general competition, whereby the desire of rising becomes no longer the character of a particular class, but of all classes."
