"The value of a book, among other things, is also measured by whether its owner will feel the need, after some time has passed since the first reading, to seek it again. To remember something, to help him in his effort to put things in their place, to recover the material that is necessary in order to explain the current situation. From this point of view, this book is sure to be needed several times in the future."
