23. And I marveled that I now loved thee, and no fantasm in thy stead, and yet I was not stable enough to enjoy my God steadily. Instead I was transported to thee by thy beauty, and then presently torn away from thee by my own weight, sinking with grief into these lower things. This weight was carnal habit. But thy memory dwelt with me, and I never doubted in the least that there was One for me to cleave to; but I was not yet ready to cleave to thee firmly. For the body which is corrupted presses down the soul, and the earthly dwelling weighs down the mind, which muses upon many things. My greatest certainty was that "the invisible things of thine from the creation of the world are clearly seen, being understood by the things that are made, even thy eternal power and Godhead." For when I inquired how it was that I could appreciate the beauty of bodies, both celestial and terrestrial; and what it was that supported me in making correct judgments about things mutable; and when I concluded, "This ought to be thus; this ought not"--then when I inquired how it was that I could make such judgments (since I did, in fact, make them), I realized that I had found the unchangeable and true eternity of truth above my changeable mind.
And thus by degrees I was led upward from bodies to the soul which perceives them by means of the bodily senses, and from there on to the soul's inward faculty, to which the bodily senses report outward things--and this belongs even to the capacities of the beasts--and thence on up to the reasoning power, to whose judgment is referred the experience received from the bodily sense. And when this power of reason within me also found that it was changeable, it raised itself up to its own intellectual principle, and withdrew its thoughts from experience, abstracting itself from the contradictory throng of fantasms in order to seek for that light in which it was bathed. Then, without any doubting, it cried out that the unchangeable was better than the changeable. From this it follows that the mind somehow knew the unchangeable, for, unless it had known it in some fashion, it could have had no sure ground for preferring it to the changeable. And thus with the flash of a trembling glance, it arrived at that which is. And I saw thy invisibility [invisibilia tua] understood by means of the things that are made. But I was not able to sustain my gaze. My weakness was dashed back, and I lapsed again into my accustomed ways, carrying along with me nothing but a loving memory of my vision, and an appetite for what I had, as it were, smelled the odor of, but was not yet able to eat.
