On the Edge of Reason (Croatian: Na rubu pameti) is a 1938 novel by Miroslav Krleža.

After attending a party, surrounded by high class, he sharply criticizes the Director-General, after the latter tells an anecdote how he shot four people for trespassing on his property.

[2] Following its initial publication in Zagreb, the work was condemned by a number of critics (mainly on the left) for supposedly equating communism (in its Stalinist form) with fascist methods and for not presenting a genuine worldview.

[2] A review for Publishers Weekly described Krleža as a "shrewd observer of man as social animal, and his wry, sardonic style fits cleanly into the Eastern European tradition of bureaucratic satire by the likes of Kafka, Karel Capek and Jaroslav Hasek".

[5] In a review for Boston Phoenix, Paul West notes that "the marvel about this novel is that, for all its restrictedness and Balkan didacticism, it remains in the mind as blatant as a tattooed orange, ever perched close to wit, and empirically crisp".
