"Wäre es mir gelungen, dann hätte man mich gekrönt, so aber muß ich hinter Schloß und Riegel."

"For be a man’s intellectual superiority what it will, it can never assume the practical, available supremacy over other men, without the aid of some sort of external arts and entrenchments, always, in themselves, more or less paltry and base. This it is, that for ever keeps God’s true princes of the Empire from the world’s hustings; and leaves the highest honors that this air can give, to those men who become famous more through their infinite inferiority to the choice hidden handful of the Divine Inert, than through their undoubted superiority over the dead level of the mass."

"Muß ich, dachte er, durch das Geschwätz dieser niedrigsten Organe – sie geben selbst zu, es zu sein – mich noch mehr verwirren lassen? Sie reden doch jedenfalls von Dingen, die sie gar nicht verstehen. Ihre Sicherheit ist nur durch ihre Dummheit möglich. Ein paar Worte, die ich mit einem mir ebenbürtigen Menschen sprechen werde, werden alles unvergleichlich klarer machen als die längsten Reden mit diesen."
