Also the difference of conditions in the world of beings is an obstacle to comprehension. For example, this mineral belongs to the mineral kingdom; however far it may rise, it can never comprehend the power of growth. The plants, the trees, whatever progress they may make, cannot conceive of the power of sight or the powers of the other senses; and the animal cannot imagine the condition of man-- that is to say, his spiritual powers. Difference of condition is an obstacle to knowledge; the inferior degree cannot comprehend the superior degree. How then can the phenomenal reality comprehend the Preexistent Reality? Knowing God, therefore, means the comprehension and the knowledge of His attributes, and not of His Reality. This knowledge of the attributes is also proportioned to the capacity and power of man; it is not absolute. Philosophy consists in comprehending the reality of things as they exist, according to the capacity and the power of man. For the phenomenal reality can comprehend the Preexistent attributes only to the extent of the human capacity. The mystery of Divinity is sanctified and purified from the comprehension of the beings, for all that comes to the imagination is that which man understands, and the power of the understanding of man does not embrace the Reality of the Divine Essence. All that man is able to understand are the attributes of Divinity, the radiance of which appears and is visible in the world and within men's souls (221:1)
