Kafka's "A Hunger Artist" explores the intense isolation experienced by the exceptional individual. The title character is fanatically devoted to his art, the unusual art of starvation. Even at the height of his popularity, no one understands his art or appreciates his dedication – they're just watching him because he's the latest fad. The audience's lack of understanding only ratchets up the artist's loneliness and frustration. But hey, isolation may be the price he has to pay for his originality. The story also suggests that the hunger artist may not be starving out of devotion to his art, but simply because he's a picky eater and can't find any food he likes. The alienation experienced by the hunger artist might also stand in for the alienation experienced by anyone whose desires are outside the norm.
Kafka's "A Hunger Artist" is a story about the intense isolation all great artists experience.
