Our first and most pressing problem is how to do away with warfare as a method of solving conflicts between national groups or between groups within a society who have different views about how the society is to be run. If you look back, you will see that warfare was an invention, just as ways of handling government or taxes are inventions. You will see, too, that once people use an invention they go on using it until they find another which they think is superior.
