This difference of character lies probably close on the confines of the physical powers which move the human organism, and belongs to that amphibious organisation which we call the nervous system, which appears to be partly material, partly spiritual. With our weak philosophy, we shall not proceed further in this mysterious field. But it is important for us to spend a moment over the effects which these different natures have on action in war, and to see how far a great strength of mind is to be expected from them.

Indolent men cannot easily be thrown out of their equanimity, but we cannot certainly say there is strength of mind where there is a want of all manifestation of power.

At the same time, it is not to be denied that such men have a certain peculiar aptitude for war, on account of their constant equanimity. They often want the positive motive to action, impulse, and consequently activity, but they are not apt to throw things into disorder.

The peculiarity of the second class is that they are easily excited to act on trifling grounds, but in great matters they are easily overwhelmed. Men of this kind show great activity in helping an unfortunate individual, but by the distress of a whole nation they are only inclined to despond, not roused to action.

Such people are not deficient in either activity or equanimity in war; but they will never accomplish anything great unless a great intellectual force furnishes the motive, and it is very seldom that a strong, independent mind is combined with such a character.

Excitable, inflammable feelings are in themselves little suited for practical life, and therefore they are not very fit for war. They have certainly the advantage of strong impulses, but that cannot long sustain them. At the same time, if the excitability in such men takes the direction of courage, or a sense of honour, they may often be very useful in inferior positions in war, because the action in war over which commanders in inferior positions have control is generally of shorter duration. Here one courageous resolution, one effervescence of the forces of the soul, will often suffice. A brave attack, a soul-stirring hurrah, is the work of a few moments, whilst a brave contest on the battlefield is the work of a day, and a campaign the work of a year.

Owing to the rapid movement of their feelings, it is doubly difficult for men of this description to preserve equilibrium of the mind; therefore they frequently lose head, and that is the worst phase in their nature as respects the conduct of war. But it would be contrary to experience to maintain that very excitable spirits can never preserve a steady equilibrium -- that is to say, that they cannot do so even under the strongest excitement. Why should they not have the sentiment of self-respect, for, as a rule, they are men of a noble nature? This feeling is seldom wanting in them, but it has not time to produce an effect. After an outburst they suffer most from a feeling of inward humiliation. If through education, self-observance, and experience of life, they have learned, sooner or later, the means of being on their guard, so that at the moment of powerful excitement they are conscious betimes of the counteracting force within their own breasts, then even such men may have great strength of mind.

Lastly, those who are difficult to move, but on that account susceptible of very deep feelings, men who stand in the same relation to the preceding as red heat to a flame, are the best adapted by means of their titanic strength to roll away the enormous masses by which we may figuratively represent the difficulties which beset command in war. The effect of their feelings is like the movement of a great body, slower, but more irresistible.

Although such men are not so likely to be suddenly surprised by their feelings and carried away so as to be afterwards ashamed of themselves, like the preceding, still it would be contrary to experience to believe that they can never lose their equanimity, or be overcome by blind passion; on the contrary, this must always happen whenever the noble pride of self-control is wanting, or as often as it has not sufficient weight. We see examples of this most frequently in men of noble minds belonging to savage nations, where the low degree of mental cultivation favours always the dominance of the passions. But even amongst the most civilised classes in civilised states, life is full of examples of this kind -- of men carried away by the violence of their passions, like the poacher of old chained to the stag in the forest.
