“The downfall of civilized states tends to come not from the direct assaults of foes, but from internal decay combined with the consequences of exhaustion in war.”

It is folly to imagine that the aggressive types, whether individuals or nations, can be bought off … since the payment of danegeld stimulates a demand for more danegeld. But they can be curbed. Their very belief in force makes them more susceptible to the deterrent effect of a formidable opposing force.

If you want peace, understand war.

In should be the duty of every soldier to reflect on the experiences of the past, in the endeavor to discover improvements, in his particular sphere of action, which are practicable in the immediate future.

War is always a matter of doing evil in the hope that good may come of it.

Avoid self-righteousness like the devil- nothing is so self-blinding.

An army should always be so distributed that its parts can aid each other and combine to produce the maximum possible concentration of force at one place, while the minimum force necessary is used elsewhere to prepare the success of the concentration.

The more closely [the German army] converged on [Stalingrad], the narrower became their scope for tactical manoeuvre as a lever in loosening resistance. By contrast, the narrowing of the frontage made it easier for the defender to switch his local reserves to any threatened point on the defensive arc.

In war, the chief incalculable is the human will.

Guerrilla war is a kind of war waged by the few but dependent on the support of many.

In a campaign against more than one state or army, it is more fruitful to concentrate first against the weaker partner than to attempt the overthrow of the stronger in the belief that the latter’s defeat will automatically involve the collapse of the others.

To ensure attaining an objective, one should have alternate objectives. An attack that converges on one point should threaten, and be able to diverge against another. Only by this flexibility of aim can strategy be attuned to the uncertainty of war.

The implied threat of using nuclear weapons to curb guerrillas was as absurd as to talk of using a sledge hammer to ward off a swarm of mosquitoes.

I used to think that the causes of war were predominantly economic. I came to think that they were more psychological. I am now coming to think that they are decisively “personal,” arising from the defects and ambitions of those who have the power to influence the currents of nations.

The military weapon is but one of the means that serve the purposes of war: one out of the assortment which grand strategy can employ.

For whoever habitually suppresses the truth in the interests of tact will produce a deformity from the womb of his thought.

Air Power is, above all, a psychological weapon – and only short-sighted soldiers, too battle-minded, underrate the importance of psychological factors in war.

He who rejects change is the architect of decay.

Flee sloth; for the indolence of the soul is the decay of the body.

History fails to record a single precedent in which nations subject to moral decay have not passed into political and economic decline. There has been either a spiritual awakening to overcome the moral lapse or a progressive deterioration leading to ultimate national disaster.

He who rejects change is the architect of decay.

Even if you make mistakes, I go back to those things, my not-so-great moments because those are my truest moments; those are my human moments. I’m not even mad at the things I said that were a little dicey.

Everything that makes diversity of kinds, of species, differences, properties… everything that consists in generation, decay, alteration and change is not an entity, but a condition and circumstance of entity and being, which is one, infinite, immobile, subject, matter, life, death, truth, lies, good and evil.

A debt may get mouldy, but it never decays.
