The book is fascinating, and useful for understanding where many of our words have come from. Moreover, it makes these easier to remember by giving them in associated waves. Giving the words in waves provides Barfield an occasion to comment on the temperament of the times and the interest of the people then. In other words, he can comment on the inner considerations that go along with the outer events that also affect people. So the book provides a history of ideas and of the tendencies of civilizations. What Barfield also does, and what he really wants to do, is to show us how human awareness of ideas has changed and grown over the years. He makes fascinating and interesting points about the evolution of consciousness just by looking at English words, their sources, changes and derivations.
Usually Barfield is difficult, but this book is not so, and is as interesting as all the rest.
