For Wednesday, March 8, 2017 (with apologies for being a day late):
… At best one can advise that punctuation marks be handled the way musicians handle forbidden chord progressions and incorrect voice-leading. In every act of punctuation, as in every such musical cadence, one can tell whether there is an intention or whether it is pure sloppiness. To put it more subtly, one can sense the difference between a subjective will that brutally demolishes the rules and a tactful sensitivity that allows the rules to echo in the background even where it suspends them.
Theodor Adorno, “Punctuation Marks” (1956)
