Hinderances to Correct Judgment: Emotion & Passion

One of the greatest hindrances of correct judgment is inordinate excitement of emotion and passion. Whatever may be the cause of it, it is well known, that, when the passions are excited in a considerable degree, the mind finds it difficult to perceive the relations in propositions, particularly those which are of an abstract nature, and to combine them together so as to deduce the true result. And accordingly if a person has before him some difficult subject for examination, one requiring either by its results or its nature a careful and strong mental effort, we generally find him very solicitous to be freed, during the process in which he is engaged, from all exciting and passionate influences. 

It is hardly necessary to say here, after the remarks which have been made at various times, that faith in God tends to subdue and calm every thing of this kind. And I think it may be said with truth, that it is a matter of common Christian consciousness, which Christians will verify by their testimony, that when they are in their best religious state by strong faith and by consequent freedom from worldly passions, they are in the best condition to decide promptly and correctly upon all questions, whether moral or prudential, which require their attention.

Faith and Good Judgment

We have seen something in the remarks which have been made in some of the preceding chapters, of the mighty influence of faith in the regulation of the affections and the will; but it is worthy of notice, that it has influence in other parts of our nature also; and particularly in giving rectitude to the judgment. 

Knowledge, which is the result of the action of those perceptive and comparing powers, which we commonly express by the single term, the JUDGMENT, has a closer connection with a correct and thorough inward experience, than is sometimes supposed. True knowledge is the food of the purified mind; that upon which it lives and gains strength. “He, that hath the truth,” says the Savior, “heareth my voice.” False knowledge, if we may call it such, or rather falsehood, under the semblance of knowledge, may be described, on the contrary, as the soul’s poison. Looking at the subject in this point of view, it is not easy to appreciate too highly any thing, which gives precision and steadiness to those powers of the mind, in which knowledge has its source.
