I have never met with anyone who did not value his own judgment, except two persons who confessed to me that they had no judgment. And once one of these having come to see me, said to me, "Sir, I beg of you to tell me a little about such a thing; for I have no judgment to understand it;" which astonished me greatly.
We have in our own age a very remarkable example of the mortification of private judgment. It is that of a great doctor, much renowned, who composed a book entitled, "On Dispensations and Commands," which, falling one day into the hands of the Pope, he judged that it contained some erroneous propositions. He wrote to this doctor that he should erase them from his book. This doctor, upon receiving the order, submitted his judgment so absolutely, that he would not justify himself by explaining the matter, but, on the contrary, he believed that he was wrong, and had let himself be deceived by his own judgment: and, going into the pulpit, he read aloud what the Pope had written to him, took his book and tore it to pieces, and then said aloud that the Pope's judgment on this matter had been most just; that he approved with all his heart of the paternal censure and correction that he had deigned to give him, as being very just, and very mild to him, who deserved to be severely punished, and that he was greatly astonished how he could have been so blind as to let his own judgment mislead him in a thing so manifestly wrong.
He was by no means obliged to do this, because the Pope had not commanded it, but only that he should strike out of his book a certain thing which had not seemed good; for what is very remarkable, it was not heretical, nor so manifestly erroneous but that it might have been defended. He showed great virtue on this occasion, and an admirable mortification of his own judgment.
One often enough sees the senses mortified, because our own will is employed in mortifying them, and it would be a shameful thing to show ourselves rebellious against obedience; what would be said of us? But one very rarely finds the judgment well mortified. To make ourselves allow that what is commanded is good, to love it, to esteem it as a thing that is good and useful for us beyond all others, it is against this that the judgment rebels. For there are many who say, "I will certainly do as you tell me, but I see very well that it would be better otherwise." Alas, what are you doing, in thus fostering your judgment? No doubt it will intoxicate you; for there is no difference between an intoxicated person and one who is full of his own judgment.
