XVI.  This was their course.  But reason receiving us in our desire for God, and in our sense of the impossibility of being without a leader and guide, and then making us apply ourselves to things visible and meeting with the things which have been since the beginning, doth not stay its course even here.  For it was not the part of Wisdom to grant the sovereignty to things which are, as observation tells us, of equal rank.  By these then it leads to that which is above these, and by which being is given to these.  For what is it which ordered things in heaven and things in earth, and those which pass through air, and those which live in water; or rather the things which were before these, heaven and earth, air and water?  Who mingled these, and who distributed them?  What is it that each has in common with the other, and their mutual dependence and agreement?  For I commend the man, though he was a heathen, who said, What gave movement to these, and drives their ceaseless and unhindered motion?  Is it not the Artificer of them Who implanted reason in them all, in accordance with which the Universe is moved and controlled?  Is it not He who made them and brought them into being?  For we cannot attribute such a power to the Accidental.  For, suppose that its existence is accidental, to what will you let us ascribe its order?  And if you like we will grant you this:  to what then will you ascribe its preservation and protection in accordance with the terms of its first creation.  Do these belong to the Accidental, or to something else?  Surely not to the Accidental.  And what can this Something Else be but God?  Thus reason that proceeds from God, that is implanted in all from the beginning and is the first law in us, and is bound up in all, leads us up to God through visible things.  Let us begin again, and reason this out.
