The author, Robert Lane Greene, argues that language is not a static, objective system of rules, but a dynamic, fluid entity constantly evolving and changing. He criticizes the popular tendency to view language in terms of "good" and "bad" forms, arguing that such prescriptive approaches ignore the inherent diversity and fluidity of language. Greene challenges the assumption that a language is inherently superior to another, demonstrating how the notion of linguistic superiority is often used to justify political agendas, as illustrated in the cases of France, Turkey, and South Africa. Ultimately, Greene advocates for a more nuanced understanding of language as a living, evolving entity that reflects the complexities of human experience and the ever-changing nature of politics.
