" Among the things I owe to Benjamin is my acquaintance with the grotesque tales (a literary form that became impossible after Hitler and is virtually inaccessible today) of Mynona, particularly the volume entitled Rosa die schöne Schutzmannsfrau [Rosa the beautiful policeman’s wife], an unsurpassed work in this genre that almost knocked me off my chair with laughter at the time; unfortunately, I can read it today only with utter indifference. The philosophical background of these tales engaged Benjamin’s attention and then led him to a great appreciation of Mynona’s magnum opus, Schöpferische Indifferenz [Creative indifference], published under the author’s real name, Salomo Friedländer. Friedländer was an orthodox Kantian as well as a strict logician and moral philosopher in theory, but in practice he was, if anything, the prototype of a cynic, or at least he wore that mask. Since the days of the Neopathetisches Kabarett he had been acquainted with Benjamin, who frequently spoke of him in rather positive terms. Friedländer was one of the most prominent personalities in the Expressionist circle, which he himself tended to regard with amusement. "
