Strength instead of being the lusty child of passion, grows by grappling with and subduing them.

Strength is a matter of a made up mind.

It is the nature, and the advantage, of strong people that they can bring out the crucial questions and form a clear opinion about them. The weak always have to decide between alternatives that are not their own.

It is truly said: It does not take much strength to do things, but it requires great strength to decide what to do.

Don't expect to build up the weak by pulling down the strong.

Our real problem, then, is not our strength today; it is rather the vital necessity of action today to ensure our strength tomorrow.

We acquire the strength we have overcome.

Superior strength is found in the long run to lie with those who had right on their side.

Strength was the virtue of paganism; obedience is the virtue of Christianity.

What the lion cannot manage to do the fox can.

Don't hit at all if it is honorably possible to avoid hitting, but never hit soft.

The burden is equal to the horse's strength.
