ABSTRACT: The author draws on by the original interpretation of the poetics of Kafka, accomplished out by Massimo Cacciari. The basic idea is that the absurd situations narrated by Bohemian writer show a paradoxical condition, in wich the protagonists can act and yet at the same time they can not act. The author argues that the fundamental antinomian structure of the events, descibed in the tales of Kafka, and emphasized by Cacciari, is a authentic logical contradiction.

KEYWORDS: Promise, advance, occasion, paradox, contradiction.
