study of sadra`s judgemet between philosophy and mysticism about divine essence

divine essence and explanation of his ontological place is an important problem for religious schools in conceptual and direct knowledge and both the philosophers and mystics concerns about it. mystics believed the method of intuition, but afterwards the emergence of speculative mysticism, they try to translate the intellectual intuition to conceptual knowledge, attaining this purpose, they use conceptual issues and consideration of being.in their opinion, divine essence is the divisible un-conditioned manner whereas the islamic philosophers believe that god exist as negatively conditioned manner, hence this is one of the points of difference between mystics and philosophers. mulla sadra and others have followed him, by interpretation and coincidence between un-conditioned manner and reality of being, try to solve the apparent conflict between mystics and philosophers.in this paper, in a comparative-analysis method we have shown that, first: philosophers never agree whit mystics and basically, the divisible un-conditioned manner that mystics adopt, in philosophers view is a conceptual respect and according to their principles, cannot exist as an independent, real being.second: by a critical perspective view, we have shown that the mystics view derived from a mistake between epistemology and ontology.
