If you entrench yourself behind strong fortifications, you compel the enemy seek a solution elsewhere.

In war the will is directed at an animate object that reacts.

Many intelligence reports in war are contradictory; even more are false, and most are uncertain.

The bloody solution of the crisis, the effort for the destruction of the enemy's forces, is the first-born son of war.

Rather than comparing [war] to art we could more accurately compare it to commerce, which is also a conflict of human interests and activities; and it is still closer to politics, which in turn may be considered as a kind of commerce on a larger scale.

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.

I shall proceed from the simple to the complex. But in war more than in any other subject we must begin by looking at the nature of the whole; for here more than elsewhere the part and the whole must always be thought of together.
