The Marxist dialectic is essentially word-fetishism. Every article of the faith is embodied in a word fetish whose double or even multiple meaning makes it possible to unite incompatible ideas and demands. The interpretation of these words, as intentionally ambiguous as the words of the Delphic Pythia, eventually brings the different parties to blows, and everyone quotes in his favour passages from the writings of Marx and Engels to which authoritative importance is attached.
