The greatest firmness is the greatest mercy.
A wise man who stands firm is a statesman, a foolish man who stands firm is a catastrophe.
Steadfastness is a noble quality, but unguided by knowledge or humility it becomes rashness or obstinacy.
The purpose firm is equal to the deed.
Firmness of purpose is one of the most necessary sinews of character, and one of the best instruments of success. Without it genius wastes its efforts in a maze of inconsistencies.
Real firmness is good for anything; strut is good for nothing.
It is only persons of firmness that can have real gentleness. Those who appear gentle are, in general, only a weak character, which easily changes into asperity.
