The pages are like brand new. The hardcover has some wear on it. The book is old but has only been used once. There is writing only on the first page, after that, all the pages are crisp and clean, no highlighting or other writing. This is an extraordinary book that takes a deep look at the many aspects of human thinking and the developing brain. It is easy to understand and packed with information. *Smoke free & Pet Free home **Thank you for viewing my book. 👱‍♀️
