THE PEN IS MIGHTIER THAN THE SWORD.

I have rethought this and think this is just another form of brainwashing. The pen represents words the sword is physical.
Pen=Laws, Lawyers,Governments, systems etc
Sword= Muscle, strength, police, military etc.

Laws works because the police will come for you=sword
Lawyers are feared because somehow the police gets involved=sword
Governments are feared because police and military comes for you-using force=sword

Now remove the sword from the equation and what do we have-just words. Words cannot hurt you unless you let it.
So all the talking and writing of laws by governments is useless if it's not backup with the sword=police military etc.
The pen is only might because of the sword.
The sword is always mighty though.
