The Present article aims at studying three discursive waves of the western Modernity exploring the declining process of political theorization. In this regard, the article will point to the discursive wave of rationality, the Rationality which had claimed to shed the light over the whole of human life. Upon the arrival of the Marxist discourse in the second wave of Modernity, a thinking capacity emerged dominant while attempting to marginalize the discourse of rationality. Truly, the discourse of the second wave was value- oriented which in its turn helped the level of liberal theorizations become upgraded. Although the two discourses opposed one another, they were methodologically rooted in the positivist tradition.  As far as the methodological tradition of the two mentioned discourses concerned postmodern thinking emerged up to criticize positivist tradition. Considering the third wave of Modernity from the lens of Derridean philosophy the metaphysics of the presence is to be deconstructed and at the same time to be faced with the impossibility of the ethical action. Combining philosophy, linguistics and psychology, Derrida has opened up a horizon for the development of discourse analysis.These human findings are outstanding from two angles. First, these philosophical investigations should be seen as a complete periodisation of western philosophy and second they should be considered as a waning process of western philosophy- surfaced in the theorization of the thinkers of the third wave. In sum, investigating the waning process of western philosophy could open up the routes to native Islamic philosophy. This can be followed in the lense of crisis disturbed the ethical arena of the western civilization.
