The principal agent is the object itself and not the instruction given by the teacher. It is the child who uses the objects; it is the child who is active, and not the teacher.
Maria MontessoriThe child's conquest of independence begins with his first introduction to life. While he is developing, he perfects himself and overcomes every obstacle that he finds in his path. A vital force is active within him, and this guides his efforts towards their goal. It is a force called the 'horme', by Sir Percy Nunn.
