That's why I'm calling for a Slow Books Movement (one that's a little more developed than this perfectly admirable attempt).

In our leisure moments, whenever we have down time, we should turn to literature—to works that took some time to write and will take some time to read, but will also stay with us longer than anything else. They'll help us unwind better than any electronic device—and they'll pleasurably sharpen our minds and identities, too.

To borrow a cadence from Michael Pollan: Read books. As often as you can. Mostly classics.

Aim for 30 minutes a day. You can squeeze in that half hour pretty easily if only, during your free moments—whenever you find yourself automatically switching on that boob tube, or firing up your laptop to check your favorite site, or scanning Twitter for something to pass the time—you pick up a meaningful work of literature. Reach for your e-reader, if you like. The Slow Books movement won't stand opposed to technology on purely nostalgic or aesthetic grounds. (Kindles et al make books like War and Peace less heavy, not less substantive, and also ensure you'll never lose your place.)

But Slow Books will have standards about what kinds of reading materials count towards your daily quota. Blog posts won't, of course, but neither will newspaper pieces or even magazine articles.

Also excluded: non-literary books.

Why the emphasis on literature? By playing with language, plot structure, and images, it challenges us cognitively even as it entertains. It invites us to see the world in a different way, demands that we interpret unusual descriptions, and pushes our memories to recall characters and plot details. In fact, as Annie Murphy Paul noted in a March 17 New York Times op-ed, neuroscientists have found plenty of proof that reading fiction stimulates all sorts of cognitive areas—not just language regions but also those responsible for coordinating movement and interpreting smells. Because literary books are so mentally invigorating, and require such engagement, they make us smarter than other kinds of reading material, as a 2009 University of Santa Barbara indicated. Researchers found that subjects who read Kafka's "The Country Doctor"—which includes feverish hallucinations from the narrator and surreal elements—performed better on a subsequent learning task than a control group that read a straightforward summary of the story. (They probably enjoyed themselves a lot more while reading, too.)

Literature doesn't just make us smarter, however; it makes us us, shaping our consciences and our identities. Strong narratives—from Moby-Dick to William Styron's suicide memoir, Darkness Visible—help us develop empathy. Research by Canadian psychologists Keith Oatley and Raymond Mar suggests that reading fiction even hones our social skills, as Paul notes. "Dr. Oatley and Dr. Mar, in collaboration with several other scientists, reported ... that individuals who frequently read fiction seem to be better able to understand other people, empathize with them, and see the world from their perspective," she writes. "This relationship persisted even after the researchers accounted for the possibility that more empathetic individuals might prefer reading novels."
