More people speak English today than any other language in human history. But what do we lose, psychologically and culturally, as a result? For this week's @newyorker.com, I explore how English shapes thought—from our conception of time to how we talk about the senses.
An estimated 1.5 billion people—roughly one in every five human beings—speak English, making it the most widely used language in the history of humanity. Some researchers worry about what we’re losing with its expansion.
How Much Does Our Language Shape Our Thinking?
English continues to expand into diverse regions around the world. The question is whether humanity will be homogenized as a result.
