Now in War, owing to the many and powerful impressions to which the mind is exposed, and in the uncertainty of all knowledge and of all science, more things occur to distract a man from the road he has entered upon, to make him doubt himself and others, than in any other human activity. The harrowing sight of danger and suffering easily leads to the feelings gaining ascendency over the conviction of the understanding; and in the twilight which surrounds everything a deep clear view is so difficult that a change of opinion is more conceivable and more pardonable. It is, at all times, only conjecture or guesses at truth which we have to act upon. This is why differences of opinion are nowhere so great as in War, and the stream of impressions acting counter to one’s own convictions never ceases to flow. Even the greatest impassibility of mind is hardly proof against them, because the impressions are powerful in their nature, and always act at the same time upon the feelings. When the discernment is clear and deep, none but general principles and views of action from a high standpoint can be the result; and on these principles the opinion in each particular case immediately under consideration lies, as it were, at anchor. But to keep to these results of bygone reflection, in opposition to the stream of opinions and phenomena which the present brings with it, is just the difficulty. Between the particular case and the principle there is often a wide space which cannot always be traversed on a visible chain of conclusions, and where a certain faith in self is necessary and a certain amount of scepticism is serviceable. Here often nothing else will help us but an imperative maxim which, independent of reflection, at once controls it: that maxim is, in all doubtful cases to adhere to the first opinion, and not to give it up until a clear conviction forces us to do so. We must firmly believe in the superior authority of well-tried maxims, and under the dazzling influence of momentary events not forget that their value is of an inferior stamp. By this preference which in doubtful cases we give to first convictions, by adherence to the same our actions acquire that stability and consistency which make up what is called character. It is easy to see how essential a well-balanced mind is to strength of character; therefore men of strong minds generally have a great deal of character. Force of character leads us to a spurious variety of it—OBSTINACY. It is often very difficult in concrete cases to say where the one ends and the other begins; on the other hand, it does not seem difficult to determine the difference in idea.
