Very well then! Emancipation from huckstering and money, consequently from practical, real Judaism, would be the self-emancipation of our time. An organization of society [such as communism] which would abolish the preconditions for huckstering, and therefore the possibility of huckstering, would make [this] Jew impossible. His religious consciousness would be dissipated like a thin haze in the real, vital air of society. On the other hand, if the Jew recognizes that this practical nature of his is futile and works to abolish it, he extricates himself from his previous development and works for human emancipation as such and turns against the supreme practical expression of human self-estrangement.
