Is Knowledge an Absolute Truth?

In some writings in English language there are some confusion about the nature of knowledge and mental being. As they think from Mulla? S?adra?'s points of view knowledge and mental being are identical. But Java?di? A?muli? a contemporary interpreter of Mulla? S?adra?'s texts has seen this distinction as crucially. He is of the opinion that this distinction is an important landmark in Mulla S?adra?'s philosophy as he remarks that many epistemological problems could be solved in this direction.
