52 Against these latter he observes that "while all are to be warned to enter with the utmost circumspection upon questions affecting the Sacred Scriptures, these dialecticians of our time are to be completely debarred from the discussion of spiritual questions." And the reason he assigns for this is especially applicable now to those who imitate them under our eyes, repeating their old errors: "For in their souls, reason, which should be the king and the guide of all that is in man, is so mixed up with corporal imaginations that it is impossible to disentangle it from these, nor is itself able to distinguish from them things that it alone and pure should contemplate" ( Ibid . cap. 2). Appropriate, too, for our own times are those words of his in which he ridicules those false philosophers, "who because they are not able to understand what they believe dispute the truth of the faith itself, confirmed by the Holy Fathers, just as if bats and owls who see the heaven only by night were to dispute concerning the rays of the sun at noon, against eagles who gaze at the sun unblinkingly" ( Ibid .).
