Master of the World1961

Prudent:
You, sir, are mad! Quite, quite mad!

Robur:
How like the reasoning of your kind, Mr. Prudent. All well and sane to be the owner of factories, that products of which cause the violent deaths of millions in wartime and in peace. But to kill hundreds or even thousands with the aim of ending such deaths for all time? This is "madness."

Prudent:
And do you, sir, consider the man who makes a weapon responsible for the action of the man who buys it?

Robur:
Yes, I do, sir! All men are responsible to all other men.
