Anderson: Taking the long view, history shows that word usage and grammar rules are constantly changing and evolving-sometimes resulting in entirely new languages. Since they will change regardless of our efforts, we shouldn' t worry about violations of grammar rules. Lipton: That' s like arguing that we shouldn' t worry about enforcing laws since, in the larger scheme of things, laws change and nations come and go. But of course it is good that laws are enforced. The dialogue provides the most support for the claim that Anderson and Lipton disagree over whether ['users of a language can easily adapt to changes in that language', 'grammar violations should be resisted', 'languages evolve through an accumulation of changes in usage and rules', 'people only rarely violate grammar rules']
