Returning now to the main subject, although it is true that in one kind of War the political element seems almost to disappear, whilst in another kind it occupies a very prominent place, we may still affirm that the one is as political as the other; for if we regard the State policy as the intelligence of the personified State, then amongst all the constellations in the political sky whose movements it has to compute, those must be included which arise when the nature of its relations imposes the necessity of a great War. It is only if we understand by policy not a true appreciation of affairs in general, but the conventional conception of a cautious, subtle, also dishonest craftiness, averse from violence, that the latter kind of War may belong more to policy than the first. 27. INFLUENCE OF THIS VIEW ON THE RIGHT UNDERSTANDING OF MILITARY HISTORY, AND ON THE FOUNDATIONS OF THEORY. We see, therefore, in the first place, that under all circumstances War is to be regarded not as an independent thing, but as a political instrument; and it is only by taking this point of view that we can avoid finding ourselves in opposition to all military history. This is the only means of unlocking the great book and making it intelligible. Secondly, this view shows us how Wars must differ in character according to the nature of the motives and circumstances from which they proceed. Now, the first, the grandest, and most decisive act of judgment which the Statesman and General exercises is rightly to understand in this respect the War in which he engages, not to take it for something, or to wish to make of it something, which by the nature of its relations it is impossible for it to be. This is, therefore, the first, the most comprehensive, of all strategical questions. We shall enter into this more fully in treating of the plan of a War. For the present we content ourselves with having brought the subject up to this point, and having thereby fixed the chief point of view from which War and its theory are to be studied. 28. RESULT FOR THEORY. War is, therefore, not only chameleon-like in character, because it changes its colour in some degree in each particular case, but it is also, as a whole, in relation to the predominant tendencies which are in it, a wonderful trinity, composed of the original violence of its elements, hatred and animosity, which may be looked upon as blind instinct; of the play of probabilities and chance, which make it a free activity of the soul; and of the subordinate nature of a political instrument, by which it belongs purely to the reason.
