It's definitely fantastic, and one of the books that had the greatest influence on my thinking (I read it as a teenager, 20+ years ago).
If you want something less theoretical, more personal, poetic and emotional, his "Le ton beau de Marot" (English, despite the title) is also fabulous. He takes a short poem and translates it a hundred different ways, all the while musing about what "translation" means (literal, conveying the same emotion, using the same metaphors, between cultures...) as well as about thought, language and meaning more generally. And then, while he writes the book, his wife gets a brain tumor and dies, and the book becomes part of his mourning.
