Carl von Clausewitz
Carl von Clausewitz
Carl Philipp Gottfriedvon Clausewitz was a Prussian general and military theorist who stressed the "moral"and political aspects of war. His most notable work, Vom Kriege, was unfinished at his death. Clausewitz was a realist in many different senses and, while in some respects a romantic, also drew heavily on the rationalist ideas of the European Enlightenment...

war imperfection perception
[The cause of inaction in war] ... is the imperfection of human perception and judgment which is more pronounced in war than anywhere else. We hardly know accurately our own situation at any particular moment while the enemy's, which is concealed from us, must be deduced from very little evidence.
war men yield
A general in time of war is constantly bombarded by reports both true and false; by errors arising from fear or negligence or hastiness; by disobedience born of right or wrong interpretations, of ill will; of a proper or mistaken sense of duty; of laziness; or of exhaustion; and by accident that nobody could have foreseen. In short, he is exposed to countless impressions, most of them disturbing, few of them encouraging. ... If a man were to yield to these pressures, he would never complete an operation.
war diversity political
We must evaluate the political sympathies of other states and the effect war may have on them. To assess these things in all their ramifications and diversity is plainly a colossal task. Rapid and correct appraisal of them clearly calls for the intuition of a genius; to master all this complex mass by sheer methodical examination is obviously impossible. Bonaparte was quite right when he said that Newton himself would quail before the algebraic problems it could pose.
opponents situation commanders
The only situation a commander can know fully is his own: his opponent's he can know only from unreliable intelligence.
war twilight fog
The general unreliability of all information presents a special problem in war: all action takes place, so to speak, in the twilight, which, like fog or moonlight, often tends to make things seem grotesque and larger than they really are. Whatever is hidden from full view in this feeble light has to be guessed at by talent, or simply left to chance. So once again for the lack of objective knowledge, one has to trust to talent or to luck.
chance mechanic friction
This tremendous friction which cannot, as in mechanics, be reduced to a few points, is everywhere in contact with chance, and brings about effects that cannot be measured just because they are largely due to chance. ...
war may causes
The deduction of effect from cause is often blocked by some insuperable extrinsic obstacle: the true causes may be quite unknown. Nowhere in life is this so common as in war, where the facts are seldom fully known and the underlying motives even less so.
unpredictable interaction bounds
The very nature of interactions is bound to make it unpredictable.
pain war taken
However much pains may be taken to combine the soldier and the citizen in one and the same individual, whatever may be done to nationalize wars, never will it be possible to do away with the professionalism of the business; and if that cannot be done, then those who belong to it will always look upon themselves as a kind of guild, in the regulations, laws, and customs in which the "Spirit of War" finds its expression. It would be very wrong to look down upon this corporate spirit, or esprit de corps, which may and should exist more or less in every Army.
war different serious
The difficulty of accurate recognition constitutes one of the most serious sources of friction in war, by making things appear entirely different from what one had expected.
war fall simple
Everything in war is very simple, but the simplest thing is difficult. The difficulties accumulate and end by producing a kind of friction that is inconceivable unless one has experienced war. ... Countless minor incidents - the kind you can never really foresee - combine to lower the general level of performance, so that one always falls short of the intended goal. ...
war opportunity numbers
In war, where imperfect intelligence, the threat of a catastrophe, and the number of accidents are incomparably greater than any other human endeavor, the amount of missed opportunities, so to speak, is therefore bound to be greater.
war fog giving
War is the realm of uncertainty; three-quarters of the factors on which action in war is based are wrapped in a fog of greater or lesser uncertainty. ... war is the realm of chance. No other human activity gives it greater scope; no other has such incessant and varied dealings with this intruder. Chance makes everything more uncertain and interferes with the whole course of events.
war real paper
Friction is the only concept that more or less corresponds to the factors that distinguish real war from war on paper. ...
