The Necessity of Scripture in Justifying Logic By: Ronald W. Di Giacomo
Since no man has observed every instance of the law of non-contradiction, no man can justify an a priori knowledge of the universal, invariant nature of the law of non-contradiction; we need special revelation from the Divine Mind that the law of non-contradiction applies in all circumstances. Accordingly, if a universal is not revealed by an ominiscient God who knows with certainty the universality of all universals, man - unaided by special revelation - cannot deduce that the law of non-contradiction is indeed a law. The justification of all tools of reason reduce to rational inferences if God has not revealed them to man through special revelation; yet rational inferences are unjustifiable apart from a true doctrine of creation and providence, which too must be grounded in special revelation. Moreover, the law of non-contradiction presupposes truth, which too cannot be justified apart from special revelation. This is not to say that man being made in the image of God does not know the law of non-contradiction a priori. He does (and because of that he can be found guilty of bearing false witness to the truth). Yet notwithstanding, man cannot ground even that essential and basic transcendental apart from special revelation, which today is found in Scripture alone.
