In a recent episode of the How to Academy podcast, psycholinguist, Viorica Marian discusses how crucial multilingualism is to human flourishing. Her new book, The Power of Language, distils her research to share how language shapes our self-conception, our decisions, and the society we create. From the politics that underlie whether we categorise a language as a “language” or a “dialect”, to the ways language has shaped our identities or been employed to discriminate, to how maths and poetry too can be understood as languages, this episode illuminates the unimaginable power of the languages we speak.
