This reading aims to manipulates such a problematic that deals with the effects of the philosophy of monotheism (tawhid) on the contemporary theory of knowledge, through discussing the nature of the occidental contemporary epistemological turn which is characterized as “Epistemology complexity” with “G.Bachlard”, ”J.Piaget” , ” N.Loman”, arriving to “Idgar Morin”, “J.L.Lemoine”. It is an epistemology which is trying to breakdown with the paradigm of (disconnection /abbreviation /simplification /specializing /atomizing /…) transmitting to the paradigm (disconnection-connection /multi-method /interdisciplinary /reactive-construction /…) to detect the value of monotheistic knowledge that lacks interest and hadn’t got its chance of discussion, framing, and instituting all over the Islamic and Arabic world, although it is emerged since decades through intellectual projects of contemporary Muslim Arabic philosophers. This monotheistic epistemology surpasses the epistemology of complexity; it regards monotheism as a great cognitive argument rather than merely moral argument.
