"Their genuine stupidity lies hid beneath their specialism. They know their business, but are ignorant of everything which is outside it. So that to preserve their self-conceit they question everything, are crudely and crookedly critical. They appear to be sceptics and are in reality simpletons; they swamp their wits in interminable arguments. Almost all conveniently adopt social, literary, or political prejudices, to do away with the need of having opinions, just as they adapt their conscience to the standard of the Code or the Tribunal of Commerce. Having started early to become men of note, they turn into mediocrities, and crawl over the high places of the world. So, too, their faces present the harsh pallor, the deceitful coloring, those dull, tarnished eyes, and garrulous, sensual mouths, in which the observer recognizes the symptoms of the degeneracy of the thought and its rotation in the circle of a special idea which destroys the creative faculties of the brain and the gift of seeing in large, of generalizing and deducing. No man who has allowed himself to be caught in the revolutions of the gear of these huge machines can ever become great."
