In this paper, by intuitive philosophy, the writer means an ontological system which is based on a rational-inferential method in the individuation of which intuitive findings playa significant role. In other words, it is a metaphysical philosophy which, while depending on rational arguments in the affirmation and rejection of its propositions, benefits from intuitive findings in the formation of its teachings.In contrast to those who believe that intuitive philosophy is a controversial combination of various theories and, as a result, an impossible issue, the writer has tried to show that intuition can have a significant effect on an ontological system without damaging its conceptuality-i.e. methodological reliance on rational reasoning when judging its propositions. In doing so, he has referred to various ways of a philosopher's use of his or others' intuitive findings (such as determining the direction of research, opening new horizons, posing new problems, helping in the formulation of philosophical hypotheses, etc.), which are all out of the domain of the judgment and evaluation of the truth or falsity of philosophical propositions.Moreover, by presenting some examples of the above-mentioned types of the effects of intuition on Suhrawardi's Ishraqi philosophy and, particularly, Mulla Sadra's Transcendent Philosophy, the writer has considered these two philosophical systems as actual examples of intuitive philosophy. He has also referred to the superiorities of this kind of philosophy to a purely discoursive one, which is void of intuitive perceptions and findings.
