Sadraian Analysis of Causality and Removing of Quiddities

Proving the principality of the existence and the fiction of the quiddity by Mulla Sadra, the existence became the focus of the disputes, but the effects of the quiddity discussions can be seen among these topics. Mulla Sadra has provided a division of two sides from the existence based on the principality of the existence and the causal relation and he has divided the existence into copulative and inhering existence based on this rule. Copulative existence is the same as relation to its cause and in reality it has a connective nature and has no independence of its own. This analysis will have consequences on philosophical issues, including the complete alteration of the situation of the quiddity, because all possible existents that the quiddity is abstracted of them will become the applications of the copulative existence and have no independence of its own. So, they cannot be mentioned in response to the question of the nature of things, because nothing has the worthy of coming in response of quiddity unless they have existential or conceptual independence. This means that quiddities are removed and come under the scope of the concepts. Quiddity in the meaning of “that comes in response of the nature of the thing,” requires independence in concept, while the copulative truth of the contingent things takes the independence of them. Thus, what is said about essences is attributed to the concepts. On the base of the principality of the existence, quiddity in the meaning of “thing in itself” also includes only the existence and it is outside of the realm of quiddity.
