In no part of Europe are the mass of the people, and especially of the middle-classes, more utterly ignorant of the foreign policy of their own country than in England, an ignorance springing from two great sources. On the one hand, since the glorious Revolution of 1688, the aristocracy has always monopolized the direction of foreign affairs in England. On the other hand, the progressive division of labor has, to a certain extent, emasculated the general intellect of the middle-class men by the circumscription of all their energies and mental faculties within the narrow spheres of their mercantile, industrial and professional concerns. Thus it happened that, while the aristocracy acted for them, the press thought for them in their foreign or international affairs; and both parties, the aristocracy and the press, very soon found out that it would be their mutual interest to combine.
