It's a good starting text for a high school or college course, but the Internet and even moreso the last political decade have moved communication way beyond the polite exchanges envisioned by Mr. Hayakawa. Even for the 1990 timeframe of this edition, it was snobbish, looking down on popular entertainment and ignoring real, vital political problems that were smoothed over with unfaithful words. There's some good ideas in here, but I can't imagine there aren't better packages that also convey them.
1. The title is misleading because the book is only 50% about the language other 50% are authors observations (that have nothing to do with language) and his "solutions" to the worlds problems. 2. Author makes a claim - "Two valued world is bad..." and yet, when he makes his own judgments and offers his own solutions to the worlds problems, he makes the same mistake. Oversimplifies the world and solutions making them on the basis of two values. 3. Illustrations are horrible and only waste the space for potential text. 4. The print is small and some random lines have even smaller size. Overall 6.5/10 book, even tho the premises at the beginning of the book and the title are misleading, I enjoyed some of the authors observations.
