7.3.4   But I also as yet, although I held and was firmly persuaded that Thou our Lord the true God, who madest not only our souls, but our bodies, and not only our souls and bodies, but all beings, and all things, wert undefilable and unalterable, and in no degree mutable; yet understood I not, clearly and without difficulty, the cause of evil. And yet whatever it were, I perceived it was in such wise to be sought out, as should not constrain me to believe the immutable God to be mutable, lest I should become that evil I was seeking out. I sought it out then, thus far free from anxiety, certain of the untruth of what these held, from whom I shrunk with my whole heart: for I saw, that through enquiring the origin of evil, they were filled with evil, in that they preferred to think that Thy substance did suffer ill than their own did commit it.
