Engels later argued that utopian socialists failed to recognize why it was that socialism arose in the historical context that it did, that it arose as a response to new social contradictions of a new mode of production, i.e. capitalism.
Engels kemudian menyatakan bahwa sosialis utopis gagal menyadari mengapa sosialisme muncul dalam konteks kesejarahan, bahwa sosialisme muncul sebagai respon terhadap kontradiksi sosial baru dari corak produksi baru, yaitu kapitalisme.
