Thinking well takes time: time for doubt, time for analysis and synthesis, time to let your intuition operate, time to have a second thought. The faster we write, the faster we respond (on Twitter or Facebook, in discussion threads or texts), the more superficial the level of consciousness we’re working from. We’re skimming the surface of our minds (which, like the surface of other things, is mostly foam and crud), forgoing reason, judgment, artistry, craft. That is not the place from which the most intelligent forms of communication, the ones that used to play a larger role in our lives—novels, essays, serious journalism—originate. But it is the place our public discourse, and our private discourse, too, increasingly inhabits.
