But this higher activity of the mind, this glance of genius, would still not become matter of history if the qualities of temperament and character of which we have treated did not give it their support.
Truth alone is but a weak motive of action with men, and hence there is always a great difference between knowing and action, between science and art.

The man receives the strongest impulse to action through the feelings, and the most powerful succour, if we may use the expression, through those faculties of heart and mind which we have considered under the terms of resolution, firmness, perseverance, and force of character.
If, however, this elevated condition of heart and mind in the General did not manifest itself in the general effects resulting from it, and could only be accepted on trust and faith, then it would rarely become matter of history.
All that becomes known of the course of events in War is usually very simple, and has a great sameness in appearance; no one on the mere relation of such events perceives the difficulties connected with them which had to be overcome.

It is only now and again, in the memoirs of Generals or of those in their confidence, or by reason of some special historical inquiry directed to a particular circumstance, that a portion of the many threads composing the whole web is brought to light.

The reflections, mental doubts, and conflicts which precede the execution of great acts are purposely concealed because they affect political interests, or the recollection of them is accidentally lost because they have been looked upon as mere scaffolding which had to be removed on the completion of the building.
If, now, in conclusion, without venturing upon a closer definition of the higher powers of the soul, we should admit a distinction in the intelligent faculties themselves according to the common ideas established by language, and ask ourselves what kind of mind comes closest to military genius, then a look at the subject as well as at experience will tell us that searching rather than inventive minds, comprehensive minds rather than such as have a special bent, cool rather than fiery heads, are those to which in time of War we should prefer to trust the welfare of our women and children, the honour and the safety of our fatherland..
