I just read The Granton Star Cause in Irvine Welsh’s short story collection, The Acid House, and couldn’t help but reflect it off of Kafka’s Metamorphosis.

Kafka gave us Gregor Samsa: a man who wakes up as vermin, stripped of usefulness, abandoned by family, slowly rotting in a godless universe. His tragedy is inertia; his metamorphosis grants him no agency, only deeper alienation.

Welsh replies with Boab Coyle, a lad who is likewise cast off, rejected by his football mates, scorned by his parents, dumped by his girlfriend, and discarded by his job. Boab is surplus to every domain: civic, familial, erotic, and economic. Then he undergoes his own metamorphosis. And here Welsh swerves from Kafka.

Boab meets his “god.” But the god is nothing transcendent. It is simply Boab’s latent agency, given a mask – a projection of his bitterness and thwarted desires. God looks like him, speaks like him, and tells him to act on impulses long repressed. Where Kafka leaves Gregor to die in silence, Welsh gives Boab a grotesque theology of vengeance.

Through a Critical Theory lens, the contrast is stark:

• Marx: Both men are surplus. Gregor is disposable labour; Boab is Thatcher’s lumpen. Alienated, both become vermin.
• Nietzsche: Gregor has no god, only the absurd. Boab makes one in his own image, not an Übermensch, but an Über-fly – quite literally a Superfly – a petty deity of spite.
• Foucault: Gregor is disciplined into passivity by the family gaze. Boab flips it: as a fly, he surveils and annoys, becoming the pest-panopticon.
• Bataille/Kristeva: Gregor embodies the abjection of his family’s shame. Boab revels in abjection, weaponising filth as his new mode of agency.

The punchline? Boab’s new god-agency leads straight to destruction. His rage is cathartic, but impotent. The lumpen are permitted vengeance only when it consumes themselves.

So Kafka gave us the tragedy of stasis; Welsh provides us with the tragedy of spite. Both are bleak parables of alienation, but Welsh injects a theology of bad attitude: a god who licenses action only long enough to destroy the actor.

Gregor rots. Boab rages. Both end the same way.
