Linguist, professor, and author John McWhorter has featured on Sentence first a few times before, in posts about texting, creoles, dialects, linguistic complexity, and book spine poems. He has written many books and countless articles about language, and has been hosting the excellent Lexicon Valley podcast for the last while.
In the video below, McWhorter talks about the ideas in his recent book The Language Hoax, the hoax being the Sapir–Whorf hypothesis, aka linguistic determinism or relativity, depending on how strongly it’s believed to apply.* This is the appealing but mostly unfounded notion that our language shapes the world we experience. There’s a helpful summary of it here, and further discussion in this book review.
The subtitle of McWhorter’s talk, ‘Why the world looks the same in any language’, outlines his position. But he acknowledges there is wiggle room for weak versions of the hypothesis, whereby our perceptions can vary slightly because of our different native languages. It’s a fun and interesting talk, given at the Santa Fe Institute in New Mexico in 2016. It’s around 50 minutes long, and there’s a lively Q&A to finish.
* Hoax connotes fraudulence, which is misleading; think of it instead as a fallacy, myth, or misapprehension.
