Fascinating! Deutscher's writing is clear and interesting with some humor thrown in. He explains about how culture affects language and how our native language affects memory, perception and associations as well as practical skills such as orientation.
In some languages there is no left, right, behind but everything is described as north, south of you and the speakers of the language develop an unerring sense of geographical direction.
He discusses that in some languages, even words that are about people do not have gender--neighbor, friend, cousin in English but in other languages (i.e. French or Spanish)the speaker has to disclose the gender of the person. And in some languages some verbs can be used without a tense, so the speaker does not have to disclose whether they ate, are eating or will eat.
Anyway, Deutscher does a much better job of discussing how language impacts the way we see the world.
