A mаn оf оverly аcute cоnsciousness…considers himself not аs a person, but a mouse…[the man of nature and truth], with his innate stupidity, considers his revenge nothing more than justice, pure and simple; but the mouse…rejects the idea of justice…the mouse has already managed to pile up all sorts of other nastiness around itself in the form of hesitations and doubts; so many unresolved questions…some kind of stinking mess consisting of doubts, anxieties…There, in its disgusting, stinking [hole], our offended, crushed, and ridiculed mouse immediately plunges into cold, malicious, and, above all, everlasting spitefulness. For forty years on end it will recall its insult down to the last, most shameful detail; and each time it will add more shameful details of its own, spitefully teasing and irritating itself with its own fantasy…Perhaps it will even begin to take revenge, but only in little bits and pieces, in trivial ways, from behind the stove, incognito, not believing in its right to be revenged, nor in the success of its own revenge.
