Mulla Sadra`s Union-Based Approach to the Theory of the Oneness of Intellect and What Perceived by Intellect on the Basis of human Soul`s Simplicity

The unity of the knowing and the known, as a theory, has a special place in transcendent philosophy. Some philosophers including Ibn Sina, have denied the theory; Mulla Sadra, however, agrees with it. This disagreement is due to the differences founded in their philosophical foundations; so that one may say: this theory can only be conceived on the basis of transcendent philosophy. The content of this theory, on the basis of common views, is the unification of human mind with its scientific forms. Mulla Sadra's specific principles and theories about the nature of the soul as well as in epistemology allow for a specific interpretation of this rule. The common view of the process of perception lie in the effect of the outside world and the ascendant state of knowledge, there may be found a downward spiral of knowledge. On the basis of the simplicity of human soul, every object in the outside world has a principle and reality in the inner of rational order of man. Given appearance of this simplicity, all rational, imaginary, and sensory perceptions would appear in downward orders of sense and imagination.  emergence of that principle in the far infrared, including imagination and sense. Mulla Sadra considers this field of knowledge in his theory of which the best expression, regarding the unity of zahir and mazhr, is the unity of the knowledge, the knowing and the known.
