Comparing the Functions of Intellect from the Viewpoint of Mullasadra and Holy Quran

According to philosophers intellect is the rational faculty of the soul, by which one can understand the truth universally. Now the question is how much this definition of intellect conforms to the Quran's view. Islamic Philosophers believe that intellect has got various capabilities to reach differing degrees. In the lower degrees intellect can deduce, analyze and synthesize the concepts. Through contemplation, reflection as well as purification, this faculty could develop and would be able to connect with the world beyond and unify with separated intelligences and reach the truth immediately.  Thus, the intellect controls the whole cognitive activities of human being including understanding, deduction, assessment, development, spiritual observation and his practical actions. In other words, the real existential dimension of man always thinks and acting accordingly. This concept of intellect is the one Quran verses admitted.
