Alexis de Tocqueville 
Democracy in America — Volume 2 [EPUB ebook] 

De Tocqueville's Preface To The Second Part
The Americans live in a democratic state of society, which has naturally suggested to them certain laws and a certain political character. This same state of society has, moreover, engendered amongst them a multitude of feelings and opinions which were unknown amongst the elder aristocratic communities of Europe: it has destroyed or modified all the relations which before existed, and established others of a novel kind. The—aspect of civil society has been no less affected by these changes than that of the political world. The former subject has been treated of in the work on the Democracy of America, which I published five years ago; to examine the latter is the object of the present book; but these two parts complete each other, and form one and the same work.
I must at once warn the reader against an error which would be extremely prejudicial to me. When he finds that I attribute so many different consequences to the principle of equality, he may thence infer that I consider that principle to be the sole cause of all that takes place in the present age: but this would be to impute to me a very narrow view.
