... написал два трактата о числах. Ими доволен вполне. Удалось вывести две теоремы, потом опровергнуть их, потом опровергнуть опровержение, а потом снова опровергнуть. На этом основании удалось вывести еще две теоремы... Выводы оказались столь неожиданные, что я, благодаря им, стал сильно смахивать на естественного мыслителя. Да вдобавок еще естественного мыслителя из города Курска. Скоро мне будет как раз к лицу заниматься квадратурой круга или трисекцией угла. Деятельность малограмотного ученого всегда была мне приятна.
