Learn While You Sleep reports concisely (but fully) the views of the great scholars of the past and present on this subject. Their conclusions about methods of learning, about memory, and about the role of the unconscious in the process of learning and recall are summarized and considered in relation to this approach which I call "learning plus." The idea of learning in one's sleep is not new. But because our modern world offers so many ingenious devices educators are able, for die first time, to help their students learn more effectively. Valuable time can be saved, freeing the student (and here I use the word student in its broadest sense) for more advanced thought and further study in related fields.
