"If this conflict had taken place toward the end of the Middle Ages, both sides in slaughtering each other would have cited the same text from the Bible. Formalist historians would afterwards have come to the conclusion that they were fighting about the correct interpretation of texts. The craftsmen and illiterate peasants of the Middle Ages had a strange passion, as is well known, for allowing themselves to be killed in the cause of philological subtleties in the Revelations of Saint John, just as the Russian Separatists submitted to extermination in order to decide the question whether one should cross himself with two fingers or three. In reality there lies hidden under such symbolic formulae – in the Middle Ages no less than now – a conflict of life interests which we must learn to uncover. The very same verse of the Evangelist meant serfdom for some, freedom for others...Political slogans serve oftener to disguise interests than to call them by name."
