Is there a domain beyond the illogical intellect whose statements are antirational? This question has always called gnosticism to encounter rationalism. Thus, gnostics, gnosticologists, and religionologists in both Christian west and Islamic east have always paid attention to intellect and the extraintellectual order, and to the possible relationthip between them. Mulla Sadra believed that neither the statements of the intellect are invalid in the extra intellectual order, nor the statements of the latter in the former. Kierkegaard, on the other hand, in his notion of human life stages, has labeled them as esthetic, ethical, and religious. In his view, the religious domain is extra-rational and extra-ethical. In an analytic process, Mulla Sadra has classified the implications and applications of the word "intellect". In his view, intellect is present in overall human domains and no order of humanity is void of the power of reason.
