More on why we cannot know God

Continuing a comment on the previous post:

"Know that there are two kinds of knowledge: the knowledge of the essence of a thing and the knowledge of its qualities. The essence of a thing is known through its qualities; otherwise, it is unknown and hidden.

As our knowledge of things, even of created and limited things, is knowledge of their qualities and not of their essence, how is it possible to comprehend in its essence the Divine Reality, which is unlimited? For the inner essence of anything is not comprehended, but only its qualities. For example, the inner essence of the sun is unknown, but is understood by its qualities, which are heat and light. The inner essence of man is unknown and not evident, but by its qualities it is characterized and known. Thus everything is known by its qualities and not by its essence. Although the mind encompasses all things, and the outward beings are comprehended by it, nevertheless these beings with regard to their essence are unknown; they are only known with regard to their qualities.

Then how can the eternal everlasting Lord, Who is held sanctified from comprehension and conception, be known by His essence? That is to say, as things can only be known by their qualities and not by their essence, it is certain that the Divine Reality is unknown with regard to its essence and is known with regard to its attributes. Besides, how can the phenomenal reality embrace the Preexistent Reality? For comprehension is the result of encompassing—embracing must be, so that comprehension may be—and the Essence of Unity surrounds all and is not surrounded."
