Finally, I call it pure mind, or pure understanding, when it receives from God entirely pure ideas of the truth, with no admixture of sensations or images, through its union not with the body but with the Word, or the Wisdom, of God; not because it is in the sensible, material world, but because it subsists in the immaterial, intelligible world; not in order to know mutable things suited to the preservation of the life of the body, but to enter into immutable truths, which preserve in us the life of the mind.
