Secundum quod accipitur veritas ex parte rei, homo de se non habet veritatem, quia natura sua vertibilis est in nihilum; sed solum natura divina, quae nec est ex nihilo, nec vertibilis in nihilum, de se veritatem habet.
"According to what is called 'truth' on the part of the thing, man does not have truth of himself, because his nature can become nothing; but only divine nature, which neither is from nothing nor can become nothing, has truth of itself."
Super Rom. cap. 3 lect. 1
