I have begun on purpose with an elementary case, in which a very young boy might perceive an error in his books, or in his instructors, without, in any degree, forfeiting his true humility. But we will now go somewhat farther: we will take a more advanced student, such as the oldest of those among you, who are still learners, and who know that they have much to learn, but who, having been learners for some time past, have also acquired some knowledge. In the books which they refer to, and from which they are constantly deriving assistance, do they never observe any errors in the printing? do they never find explanations given, which they perceive to be imperfect, nay, which they often feel to be actually wrong? And, passing from books to living instructors, should we blame a thoughtful, attentive, and well-informed pupil, because his mind did not at once acquiesce in our interpretation of some difficult passage; because he consulted other authorities on the subject, and was unsatisfied in his judgment; the reason of his hesitation being, that our interpretation appeared to him to give an unsatisfactory sense, or to be obtained by violating the rules of language? Is he proud, rebellious, puffed up, wanting in a teachable spirit, without faith, without humility, because he so ventures to judge for himself of what his teacher tells him? Does such a judging for himself interfere, in the slightest degree, with the relation between us and him? Does it make him really cease to respect us? or dispose him to believe that he is altogether beyond the reach of our instruction? Or are we so mad as to regard our authority as wholly set at nought, because it is not allowed to be infallible? Doubtless, it would be wholly set at nought, if we had presumed to be infallible. Then it would not be merely that, in some one particular point, our decision had been doubted, but that one point would involve our authority in all; because it would prove, that we had set up beforehand a false claim: and he who does so is either foolish, or a deceiver; there is apparent a flaw either in his understanding, or in his principles, which undoubtedly does repel respect.
