The Proof on the Knowledge of Human Soul from Farabi to Mulla Sadra

The problem of the knowledge of human soul and its correlation to God's knowledge have been introduced between Muslims of the beginning of Islamic age and thought, using at correct traditions for ahl ul-bayt. Muslim philosopher's affected by Islamic teachings have studied in this respect and raised its problem as an Islamic philosophical problem. They discussed this problem from two angles: presence knowledge of soul and acquired knowledge of soul. In area of latter, they have tried to give an argument on the correlation between soul's knowledge and God's knowledge. In this paper, we have examined process of formation for this argument since Farabi to Mulla Sadra; in the paper, it has been regarded as an argument of soul's knowledge. However Prepatetics have concluded a proof on incorporeal world and the unmoved moving from this argument, but Sohravardi is the first who frankly proved the existence of God by the proof. And Later Mulla adra presented the proof by four explanations.
