The fact that a man is publicly useful, that he is a wheel, a function, is evidence of a natural predisposition; it is not society, but the only sort of happiness that the majority are capable of, that makes them intelligent machines. To the mediocre mediocrity is a form of happiness; they have a natural instinct for mastering one thing, for specialization.

Context

“The handicrafts, commerce, agriculture, science, the greater part of art, in brief, the whole range of occupational activities, are compatible only with mediocre ability and aspiration; such callings would be out of place for exceptional men; the instincts which belong to them stand as much opposed to aristocracy as to anarchism. The fact that a man is publicly useful, that he is a wheel, a function, is evidence of a natural predisposition; it is not society, but the only sort of happiness that the majority are capable of, that makes them intelligent machines. To the mediocre mediocrity is a form of happiness; they have a natural instinct for mastering one thing, for specialization. It would be altogether unworthy of a profound intellect to see anything objectionable in mediocrity in itself. It is, in fact, the first prerequisite to the appearance of the exceptional: it is a necessary condition to a high degree of civilization.” source
