Nicolaus Knüpfer, Bordeelscène, ca. 1650.

• If you were a rake headed to Philly in the 1840s, you wanted to have this pocket guide with you—it lists all the brothels in town, with some helpful editorializing about each. “None but gentlemen visit this Paradise of Love,” one description says. Another: “Beware of this house, stranger, as you would the sting of a viper.”
• A list of the one hundred most popular books on Facebook contains exactly zero surprises.
• From a new documentary on Susan Sontag: “She sat me down on her bed … and ran through the argument of the Critique of Pure Reason, Kant’s Critique of Pure Reason. She must have been fifteen.”
• “We all have bodies; we all wear clothes; we all have reflections that vex us; we all exist in dynamic relationship to our communities, and fashion is a medium for testing or strengthening those bonds … anyone who diminishes the significance of that is carrying water for the patriarchy, deferring reflexively to those thousands of years of human history when men got to decide what was frivolous or not. You know what’s frivolous? Fantasy football.”
• In 1932, Einstein endorsed a psychic. And she endorsed him: “Dr. Einstein is indeed the most remarkable personality I have ever contacted [sic]. And his aura is just sublime—pure blue electric sparks, instead of color. It was just like talking to God.” And so Einstein’s credibility as a scientist came under fire: “Now he is the tamest lion in the intellectual zoo. He goes everywhere. He attends picture openings with the regularity and aplomb of Clark Gable. He is at all the public dinners.”
