To read promiscuously is to comprehend the caresses of one work in the arms of another—and the promiscuous reader is a pedagogue par excellence. How should we read? We would read as gourmands eat, gobbling down huge gobbets of text. No one told me not to pivot abruptly from Valley of the Dolls to The Brothers Karamazov—so I did; anymore than they warned me not to intersperse passages of Fanny Hill with those written by Frantz Fanon—so I did that, too. By reading indiscriminately, I learned to discriminate—and learned also to comprehend: for it’s only with the acquisition of large data sets that we also develop schemas supple enough to interpret new material.
