The title of this book is true to its content: it is indeed a very short introduction into the origins and development of writing and writing systems. It is for the layperson, who knows nothing about the topic, yet wants a short overview of the subject and the main ideas related to it. The book does a good job in that. It’s easy to read and indeed very short, plus also provide further reading for each chapter. Thus, it can help someone with no idea start to explore these topics.
However, the book has its deficiencies.
The structure of the book could be improved, e.g we have separate chapters on the writing systems in general and on alphabets and Chinese and Japanese writing separately, but not on other writing systems. This selection is not explained. Beside, many of the useful information are scattered through the text and/or are in the “wrong chapter”.
The selection of material and the proportion of different topics is questionable. We do not get substantial information on many (minor) writing systems, nor on the scripts developed in the Middle Ages and after, yet we have elaborate expansion on the workings of Greek, Mesopotamian, Egyptian and Japanese scripts, which are way too technical. I would have preferred an even more concise summary, without any technical details (other than a few illustrative examples), but more on what we don’t know and where there is scholarly disagreement or if the book was limited to the ancient writing systems/origin of the major writing systems. I constantly had the feeling that the author likes to expand on topics with more information and research (which is natural), yet forgetting the survival bias that we have (ie that we shouldn’t make generalizations because we lost much more evidence than we have now and research is active in many topics). Although the author occasionally emphasize that our information is limited and research is ongoing, he fails to emphasize that many of the theories presented are just that - educated guesses which have not (or cannot) be checked against sufficient data. Especially in the last chapter, I would have preferred an overview on the state of research, rather than questionable statements and examples.
Overall, the book is a good material for someone with limited knowledge and interest in the history of our writing systems. For others, more substantial works are needed.
