Adam Reta, who has been writing for the last quarter of the century, has publishedrna novel and three collections of short stories and novellas. Nevertheless, the criticalrnattention given to his works was very insignificant. The authorâ€™s relationship withrnexistentialism, however, is much stronger and conspicuous. Thus, the study aimsrnat discussing the tenets of existentialism found in the creative works of AdamrnReta, which eventually gear up to elucidate his overall existentialist philosophicalrnthinking as the term existentialism applies to a bunch of philosophers, whosernphilosophical views reveal their differences rather than their similarities. To thisrnend, the philosophy of existentialism and its concepts are employed to analyze thernselected works of the author; his novel, Giracha Kachiloch, and six other narrativesrnfrom his anthologies. The researcher has also employed descriptive and textualrncriticisms as methods. From the analyses and interpretations made, the writer ofrnthis study found out that the characteristic tenets of existentialism are shared byrnAdam Reta; but with his own differences in relation to the philosophy of thernproponents of existentialism. Absurdity, alienation, freedom of choice andrnresponsibility, authenticity and inauthenticity, death and repetition are among thernmajor ones. Thus, Adam Reta is found to be a literary existentialist, who achievesrnin turning his philosophical ideas into symbols and myths, which greatly add uprnto the aesthetic value of his works.
