And yet it is plain to every one who has given any attention to the uses of words, that the word incorruption denotes by the privative particle that neither corruption nor birth appertains to God: just as many other words of like formation denote the absence of what is not inherent rather than the presence of what is; e.g. harmless, painless, guileless, undisturbed, passionless, sleepless, undiseased, impossible, unblamable, and the like. For all these terms are truly applicable to God, and furnish a sort of catalogue and muster of evil qualities from which God is separate. Yet the terms employed give no positive account of that to which they are applied. We learn from them what it is not; but what it is, the force of the words does not indicate. For if some one, wishing to describe the nature of man, were to say that it is not lifeless, not insentient, not winged, not four-footed, not amphibious, he would not indicate what it is: he would simply declare what it is not, and he would be no more making untrue statements respecting man than he would be positively defining his subject. In the same way, from the many things which are predicated of the Divine nature, we learn under what conditions we may conceive God as existing, but what He is essentially, such statements do not inform us.
