Character

The depth and strength of a human character are defined by its moral reserves. People reveal themselves completely only when they are thrown out of the customary conditions of their life, for only then do they have to fall back on their reserves.

Ends and Means

The end may justify the means as long as there is something that justifies the end.

Force

Not believing in force is the same as not believing in gravitation.

Struggle

In a serious struggle there is no worse cruelty than to be magnanimous at an inopportune time.
