To educate the human potential - Maria Montessori

The introduction explains that this book is meant to follow _Education for a New World_, and it "helps teachers envisage the child''s needs after age six." This book is part theory, part history, covering the psychology of the elementary-aged child, the history of life on Earth, and some highlights and principles of the development of civilization. This seems to be motivation and background material for the "great lessons" of the Cosmic Education as commonly used in elementary Montessori curricula. Those seeking an introduction to core Montessori theory, especially relevant to three- to six-year-olds, would be better off turning to _Education for a New World_, or the more demanding _The Absorbent Mind.
