Nevertheless, the interface pushes back with its prescribed methodologies, workflows, and limitations. Interface and artist are an antagonistic pair. Perhaps the best description of the polemic between the two is one of productive cannibalism. Just as the interface evolves under the pressure of innovation to accommodate new pragmatic uses, the artists’ will continue to deconstruct and push its aesthetic and behavioral properties to their limits.

Yanagihara’s rendering of Jude’s abuse never feels excessive or sensationalist. It is not included for shock value or titillation, as is sometimes the case in works of horror or crime fiction. Jude’s suffering is so extensively documented because it is the foundation of his character.

For the first fifty or so pages, as the characters attend parties, find apartments, go on dates, gossip, and squabble with each other, it is easy for the reader to think he knows what he’s getting into: the latest example of the postgraduate New York ensemble novel, a genre with many distinguished forbears, Mary McCarthy’s “The Group” and Claire Messud’s “The Emperor’s Children” among them.

As the pages turn, the ensemble recedes and Jude comes to the fore. And with Jude at its center, “A Little Life” becomes a surprisingly subversive novel—one that uses the middle-class trappings of naturalistic fiction to deliver an unsettling meditation on sexual abuse, suffering, and the difficulties of recovery.

In this godless world, friendship is the only solace available to any of us.

Like the axiom of equality, “A Little Life” feels elemental, irreducible—and, dark and disturbing though it is, there is beauty in it.
