Every special calling in life, if it is to be followed with success, requires peculiar qualifications of understanding and soul. Where these are of a high order, and manifest themselves by extraordinary achievements, the mind to which they belong is termed GENIUS.
We know very well that this word is used in many significations which are very different both in extent and nature, and that with many of these significations it is a very difficult task to define the essence of Genius; but as we neither profess to be philosopher nor grammarian, we must be allowed to keep to the meaning usual in ordinary language, and to understand by “genius” a very high mental capacity for certain employments.
We wish to stop for a moment over this faculty and dignity of the mind, in order to vindicate its title, and to explain more fully the meaning of the conception. But we shall not dwell on that (genius) which has obtained its title through a very great talent, on genius properly so called, that is a conception which has no defined limits. What we have to do is to bring under consideration every common tendency of the powers of the mind and soul towards the business of War, the whole of which common tendencies we may look upon as the ESSENCE OF MILITARY GENIUS. We say “common,” for just therein consists military genius, that it is not one single quality bearing upon War, as, for instance, courage, while other qualities of mind and soul are wanting or have a direction which is unserviceable for War, but that it is AN HARMONIOUS ASSOCIATION OF POWERS, in which one or other may predominate, but none must be in opposition.
