Heine, from a letter of 1842

“For our part we only know that communism, though little talked about at present, and though it lives a sickly existence in hidden garrets on miserable straw, is even so the somber hero to whom an enormous, though transitory, role is reserved in the modern tragedy, and which is only waiting for its cue to come on stage. We must never lose this actor from sight, and from time to time we will send communiqués concerning the furtive rehearsals by which it is preparing its debut. Such notices will perhaps be more important than all the reports about electoral maneuvers, party quarrels, and cabinet intrigues.”
