The examination of literary texts in different languages ​​in order to discover their affinities, relationships, or influences is known to the literary communion as comparative literary studies (Prawer 8). François Jost believes that comparative literature is to a large extent “as old as literature itself” (Jost 22); however, literature is a prerequisite for comparative literature (21). Due to the international nature of comparative literature, the literature takes the form of a universal rather than a national phenomenon (16) and is often known as world literature. Jost defines comparative literature as an organic world literature (21), “a mutual, even systematic, comparison of national literatures” (22). In this regard, the present thesis focuses on the comparison of two literary works from different nations and languages. , one being The Blind Owl by the Iranian novelist and short story writer Sadegh Hedayat, and the other Slaughterhouse-Five by the modern American novelist Kurt Vonnegut. The Blind Owl by Hedayat is the story of an anonymous painter who decides to write for his shadow about one of his unpleasant personal experiences. The narrator has isolated himself from the rest of the world and is therefore now a recluse. He was obsessed with a single painting (an old hunchbacked man sitting under a cypress tree and a young girl leaning towards him and offering him a morning glory) throughout his painting career. The narrator calls the outside world “the world of the vulgar” and resorts to alcohol and opium to forget it. The story is divided into two parts which have basic elements in common. In both parts, under the influence of opium, the narrator is plunged into an imaginary world that he feels and fears.

Fear: Like anxiety, fear protects man against the threats of a fatal situation (Tillich 81), but unlike it, fear is “directed towards a definite object” (83). Tillich's concept of fear can be best explained as "being afraid of something specific that can be faced, analyzed, attacked, endured" (Dreyer 1249). Because anxiety has no object, life establishes fear (Tillich 8) so that it protects man from the agony of non-being (Dreyer 1249).3. Courage: Courage deals with fear which is considered an object of anxiety (Tillich 70). “Existential anxiety. . . cannot be suppressed but must be taken with the courage to be” (81). Courage is approached by Tillich as the power of man to overcome fear (Dreyer 1249).
