Carl von Clausewitz Quotes

Jede Veränderung dieser Lage, welche durch die fortgesetzte kriegerische Tätigkeit hervorgebracht wird, muß also zu einer noch nachteiligeren führen, wenigstens in der Vorstellung. Die schlimmste Lage, in die ein Kriegführender kommen kann, ist die gänzliche Wehrlosigkeit. Soll also der Gegner zur Erfüllung unseres Willens durch den kriegerischen Akt gezwungen werden, so müssen wir ihn entweder faktisch wehrlos machen oder in einen Zustand versetzen, daß er nach Wahrscheinlichkeit damit bedroht sei.

Aber alle diese Opfer, welche der Verteidiger bringt, verursachen ihm meistens einen Ausfall an Kräften, die nur mittelbar, also später und nicht unmittelbar auf seine Streitkräfte wirkt, und oft so mittelbar, daß die Wirkung wenig fühlbar wird. Der Verteidiger sucht also sich auf Kosten der Zukunft im gegenwärtigen Augenblick zu verstärken, d.h. er borgt, wie jeder tun muß, der für seine Verhältnisse zu arm ist.

Wenn der Gegner unseren Willen erfüllen soll, so müssen wir ihn in eine Lage versetzen, die nachteiliger ist, als das Opfer, welches wir von ihm fordern; die Nachteile dieser Lage dürfen aber natürlich, wenigstens dem Anscheine nach, nicht vorübergehend sein, sonst würde der Gegner den besseren Zeitpunkt abwarten und nicht nachgeben.

All that was not attainable by such miserable philosophy, the offspring of partial views, lay outside the precincts of science and field of genius, which raises itself above rules.
Pity the warrior who is contented to crawl about in this beggardom of rules, which are too bad for genius, over which it can set itself superior, over which it can perchance make merry! What genius does must be the best of all rules, and theory cannot do better than to show how and why it is so.
Pity the theory which sets itself in opposition to the mind! It cannot repair this contradiction by any humility, and the humbler it is so much the sooner will ridicule and contempt drive it out of real life.

War is the province of chance. In no sphere of human activity is such a margin to be left for this intruder, because none is so much in constant contact with him on all sides. He increases the uncertainty of every circumstance, and deranges the course of events.

From this uncertainty of all intelligence and suppositions, this continual interposition of chance, the actor in War constantly finds things different from his expectations; and this cannot fail to have an influence on his plans, or at least on the presumptions connected with these plans. If this influence is so great as to render the pre-determined plan completely nugatory, then, as a rule, a new one must be substituted in its place; but at the moment the necessary data are often wanting for this, because in the course of action circumstances press for immediate decision, and allow no time to look about for fresh data, often not enough for mature consideration.

But it more often happens that the correction of one premise, and the knowledge of chance events which have arisen, are not sufficient to overthrow our plans completely, but only suffice to produce hesitation. Our knowledge of circumstances has increased, but our uncertainty, instead of having diminished, has only increased. The reason of this is, that we do not gain all our experience at once, but by degrees; thus our determinations continue to be assailed incessantly by fresh experience; and the mind, if we may use the expression, must always be “under arms”.

No one starts a war — or rather, no one in his sense ought to do so — without first being clear in his mind what he intends to achieve by that war and how he intends to conduct it.

steam boiler, delivering so and so many pounds of steam to its engines as long as the envelope can contain the pressure; but let a breach in its continuity arise — relieving the boiling water of all restraint — and in a moment the whole mass flashes into vapour, developing a power no work of man can oppose.

donde las cosas están bien ordenadas no debería haber más que un mando supremo en un mismo teatro bélico,

Se la strategia è sbagliata, la situazione non migliora aumentando i mezzi e le truppe.

If we now turn to strength of mind or soul, then the first question is, What are we to understand thereby?

Plainly it is not vehement expressions of feeling, nor easily excited passions, for that would be contrary to all the usage of language, but the power of listening to reason in the midst of the most intense excitement, in the storm of the most violent passions. Should this power depend on strength of understanding alone? We doubt it. The fact that there are men of the greatest intellect who cannot command themselves certainly proves nothing to the contrary, for we might say that it perhaps requires an understanding of a powerful rather than of a comprehensive nature; but we believe we shall be nearer the truth if we assume that the power of submitting oneself to the control of the understanding, even in moments of the most violent excitement of the feelings, that power which we call self-command, has its root in the heart itself. It is, in point of fact, another feeling, which in strong minds balances the excited passions without destroying them; and it is only through this equilibrium that the mastery of the understanding is secured. This counterpoise is nothing but a sense of the dignity of man, that noblest pride, that deeply-seated desire of the soul always to act as a being endued with understanding and reason. We may therefore say that a strong mind is one which does not lose its balance even under the most violent excitement.

The errors which proceed from a spirit of benevolence are the worst.

No one starts a war - or rather, no one in his senses ought to do so - without first being clear in his mind what he intends to achieve by that war and how he intends to conduct it.

Le troisième principe est : ne pas perdre de temps.

"Von der Goltz in excuse for the action of the late President Kruger in 1899: "The Statesman who, knowing his instrument to be ready, and seeing War inevitable, hesitates to strike first is guilty of a crime against his country.

...only a fraction of book learning will seep into practical life anyhow; and the more foolish the theory, the less of it.
