Baby Ralph has ways to pass the time in his crib—but they don’t include staring at a mobile. Aided by his mother, he reads voraciously: “All of Swift, all of Sterne, Invisible Man, Baldwin, Joyce, Balzac, Auden, Roethke,” along with a generous helping of philosophy, semiotics, and trashy thrillers. He’s also fond of writing poems and stories (in crayon). But Ralph has limits. He’s mute by choice and can’t drive, so in his own estimation he’s not a genius. Unfortunately for him, everyone else disagrees. His psychiatrist kidnaps him for testing, and once his brilliance is quantified (IQ: 475), a Pentagon officer also abducts him. Diabolically funny and lacerating in its critique of poststructuralism, Glyph has the feverish plot of a thriller and the philosophical depth of a text by Roland Barthes.
