 And if something is discovered outside all these categories which is the  cause[30]  of the realization of the quiddity of the most  fundamental[31]  thing in this category [i.e., the category of substance], then this *is more deserving to be called “being” [mawjûd] than the most perfect thing in this category, and this is the first cause of existence [wujûd] to the most perfect thing in this category, and this most perfect thing [sc. within the category of substance] is the cause in the quiddity  of*[32]  the other things in this category, and what is in this category is the cause in the quiddity of the other categories: thus the beings, where what is meant by “being” is what has a quiddity outside the soul, are ordered by this order. (I,92 p.119,4–8)
