CHAPTER LXII—That the Truth of God is the First and Sovereign Truth

THE standard in every genus is the most perfect instance of the genus. But the divine truth is the standard of all truth. The truth of our mind is measured by the object outside the mind: our understanding is called true, inasmuch as it is in accordance with that object. And again the truth of the object is measured by its accordance with the divine mind, which is the cause of all things (B. II, Chap. XXIV), as the truth of artificial objects is measured by the art of the artificer. Since then God is the first understanding and the first object of understanding, the truth of every understanding must be measured by His truth, as everything is measured by the first and best of its kind.
