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 the war and… - Carl von Clausewitz

...an intellectual instinct which extracts the essence from the phenomena of life, as a bee sucks honey from a flower. In addition to study and reflections, life itself serves as a source.

...self-reliance is the best defense against the pressures of the moment.

War is the province of danger, and therefore courage above all things is the first quality of a warrior.

Courage is of two kinds: first, physical courage, or courage in presence of danger to the person; and next, moral courage, or courage before responsibility, whether it be before the judgment-seat of external authority, or of the inner power, the conscience. We only speak here of the first.

Courage before danger to the person, again, is of two kinds. First, it may be indifference to danger, whether proceeding from the organism of the individual, contempt of death, or habit: in any of these cases it is to be regarded as a permanent condition.

Secondly, courage may proceed from positive motives, such as personal pride, patriotism, enthusiasm of any kind. In this case courage is not so much a normal condition as an impulse.

We may conceive that the two kinds act differently. The first kind is more certain, because it has become a second nature, never forsakes the man; the second often leads him farther. In the first there is more of firmness, in the second, of boldness. The first leaves the judgment cooler, the second raises its power at times, but often bewilders it. The two combined make up the most perfect kind of courage.
