He is credited with having brought Persian language and literature into the mainstream of international contemporary writing. There is no doubt that Hedayat was the most modern of all modern writers in Iran. Yet, for Hedayat, modernity was not just a question of scientific rationality or a pure imitation of European values.
In his later years, feeling the socio-political problems of the time, Hedayat started attacking the two major causes of Iran's decimation, the monarchy and the clergy, and through his stories he tried to impute the deafness and blindness of the nation to the abuses of these two major powers. Feeling alienated by everyone around him, especially by his peers, Hedayat's last published work, "The Message of Kafka", bespeaks melancholy, desperation and a sense of doom experienced only by those subjected to discrimination and repression.
Hedayat's most enduring work is the short novel "The Blind Owl" of 1937. It has been called "one of the most important literary works in the Persian language" (S.A. Qudsi).
He ended his life by gassing himself and is buried in the Père Lachaise. Hedayat's last day and night was adapted into the short film, "The Sacred and The Absurd", which was featured in the Tribeca Film Festival in 2004.
