Possible essences as such are therefore nothing actual. Furthermore, as such they have in themselves no positive being. But they are not therefore unreal. They are positively intelligible as capable of actual existence, and therefore as distinct from logical entities or _entia rationis_ which are not capable of such existence. They are present as objects of thought to mind; and to some mind other than the individual human mind. About this ideal being which they have in this Mind we have now in the next place to inquire. 18. INFERENCES FROM OUR KNOWLEDGE OF POSSIBLE ESSENCES.—We have stated that an impartial study of the _actual_ world will lead to the conclusion that it is dependent on a Supreme Intelligence; and we have suggested that in this Supreme Intelligence also possible essences as such have their primary ideal being (16, 17). When the existence of God has been established—as it may be established by various lines of argument—from _actual_ things, we can clearly see, as will be pointed out presently, that in the Divine Essence all possible essences have the ultimate source of their possibility. But many scholastic philosophers contend that the nature and properties of possible essences, as apprehended by the human mind, furnish a distinct and conclusive argument for the existence of a Supreme Uncreated Intelligence.(95) Others deny the validity of such a line of reasoning, contending that it is based on misapprehension and misinterpretation of those characteristics. All admit that it is not human thought that makes essences possible: they are intelligible to the human mind because they are possible, not _vice versa_.(96) For the human mind the immediate source and ground of their intrinsic possibility and characteristics is the fact that they are given to it in _actual_ experience while it has the power of considering them _apart from their actual existence_. But (1) are they not independent of experienced actuality, no less than of the human mind, so that we are forced to infer from them the reality of a Supreme Eternal Mind in which they have eternal ideal being?
