8 One mode, then, of knowing God, is that by the creation, which I have spoken of, and which might occupy many days. For in order that we might go over the formation of man only with exactness, (and I speak of exactness such as is possible to us, not of real exactness; since many as are the reasons we have already given for the works of creation, many more of these there are, ineffable, which God who made them knows, for of course we do not know them all); in order then, I say, that we might take an exact survey of the whole modelling of man; and that we might discover the skill there is in every member; and examine the distribution and situation of the sinews, the veins, and the arteries, and the moulding of every other part; not even a whole year would suffice for such a disquisition.
