World Labyrinth: Reconstructing Nicholaus Cusanus Conception of Substance in the light of Meister Eckhart and Ibn Sina’s Metaphyscis

Nicholaus Cusanus, as one of the greatest theologians and philosophers in Germany, through his works has tried to revise his contemporary metaphysics and its basic assumptions. He announced ground-breaking theories about creation, man's relation to the infinite, movement, epistemology and meanwhile by revisioning the common beliefs about the original sin and creatio ex nihilo wanted to introduce a well-grounded philosophical approach. In this article first we try to show his important theories about the relation between man and the infinite and by doing this we will demonstrate that in his conception there is only one substantia in se and anything other than it is its necessary accident. In addition, it will be a discussion of concepts such as decomplicatio and complicatio and in the meantime it will be introduced the concept of the substantial movement in accordance with Cusanus interpretation. After discussing these ideas, we will try to reconstruct the intellectual context in which he succeeded to develop his philosophical thoughts. In this horizon we will make an investigation in Meister Eckhart's interpretation of one or two parts of Bible and examine some basic conceptions in Ibn Sina's metaphysics. In this way we hope to demonstrate that Ibn Sina's innovative approach and unpreceded interpretations of Meister Eckhart offered a new metaphysical frame which is essentially different from the traditional one and to make it reasonable that how this enriching understanding could shed a new light on the forthcoming investigations.
