With the greatest interest and with never slackening attention I read zmdr's book, Secret of Word. Unreservedly do I recommend it to the readers of the world. Here is a book which I should like to see published in millions of copies and translated into all languages. It gives a truthful and most vivid exposition of the secret so significant to the comprehension of what really is word. These problems are widely discussed, but before one can accept or reject these ideas, he must understand the full significance of his decision. ZMDR's book will undoubtedly help to clear this question, which is the fundamental problem of learning.
