چکیده مقاله

After Mulla Sadra dealt especially with the issue of ‘principality of existence and relativity of quiddity’, later expositors attempted to present a right interpretation of this principle. Accordingly, four theories and interpretations were offered, but the selected interpretation, i.e. ‘objectivity of existence and quiddity’ is more precise and more certain than others. According to this interpretation, the reality of ‘thing itself’, for those propositions made of quiddities, is just right with essential possibility. Besides, correspondence of the mental existence with the external existence, definition of quiddity in particular sense as ‘what is said in answer to what is it’, definition of substance and accident as well as the type and division of quiddity into essential and accidental are just well and perfectly meaningful on the basis of this interpretation.
