From another point of view...
From another point of view, that of the Self which resides at the center of every self, the source of the scientia sacra revealed to man is the center and root of human intelligence itself since ultimately “knowledge of the Substance is the substance of knowledge,” or knowledge of the Origin and the Source is the Origin and Source of knowledge.
The truth descends upon the mind like an eagle landing upon a mountain top or it gushes forth and inundates the mind like a deep well which has suddenly burst forth into a spring. In either case, the sapiential nature of what the human being receives through spiritual experience is not the result of man's mental faculty but issues from the nature of that experience itself.
Man can know through intuition and revelation not because he is a thinking being who imposes the categories of his thought upon what he perceives but because knowledge is being. The nature of reality is none other than consciousness, which, needless to say, cannot be limited to only its individual human mode. Of course not everyone is capable of intellection or of having intellectual intuition no more than everyone is capable of having faith in a particular religion.
But the lack of possibility of intellection for everyone does not invalidate the reality of such a possibility any more than does the fact that many people are not able to have faith invalidate the reality of a religion. In any case for those who have the possibility of intellectual intuition there is the means to attain a knowledge of a sacred character that lies at the heart of that objective revelation which constitutes religion and also at the center of man's being.
This microcosmic revelation makes possible access to that scientist sacra which contains the knowledge of the Real and the means of distinguishing between the Real and the illusory. What we have designated as scientia sacra is none other than metaphysics if this term is understood correctly as the ultimate science of the Real.
