In post-1863-Uprising Poland, many of Spencer's ideas became integral to the dominant "fin-de-siècle" ideology, "Polish Positivism". The leading Polish writer of the period, Bolesław Prus, hailed Spencer as "the Aristotle of the nineteenth century" and adopted Spencer's metaphor of society-as-organism, giving it a striking poetic presentation in his 1884 micro-story, "Mold of the Earth", and highlighting the concept in the introduction to his most universal novel, "Pharaoh" (1895).
