Mohammed Abed al-Jabrî is a well-known thinker for his structuralist analyses and deconstruction studies on Arab/Islamic culture. As a post-colonial period intellectual, the main theme of Jabri’s work has been the question of underdevelopment, which he describes as a crisis. Jabrî suggests a new reading of Arab/Islamic culture aimed at overcoming the crisis. His proposal is aimed at building a new epistemological methodology that will enable scientific developments in Arab/Islamic thought. By analyzing the Arab/Islamic cultural heritage through structuralism, Jabiri criticized the tradition, which he saw as homogeneous integrity, by subjecting it to deconstruction and devalued it in favor of rationality in order to show that the tradition was ideologically built. But his deconstruction does not mean a total negation of tradition. The methodological construction, which Jabrî expresses as Reconstruction, refers to the rediscovery of the rational elements of the Arab / Islamic reason and its reconstruction concerning the universal reason. This article aims to criticize Jabrî’s proposal in the framework of Derrida’s deconstruction in structure and reason. Through this criticism, it will be stated that the integrity that Jabrî analyzes as a structure is fiction and that the attempt to theorize in this fiction is a sacrifice to theorize a result that can be characterized as the neglect of many factors and the game of these factors. Besides, it was aimed to reveal that Jabrî articulated the essentialism and logocentrism of the Western metaphysical tradition with his acceptance of reason, which he considered the universal reason. Jabrî’s reconstruction project seems to have been incorporated into the Western metaphysical tradition, disabling all the problems of this tradition.
