Joosten, A.M., The Montessori Movement.

„Whoever works for this ideal must be actuated by a great idea, much greater than those political ideas which have promoted social improvements which concern only the material life of some group of men oppressed by injustice or misery. This ideal is universal in its scope. It aims at the deliverance of the whole of hhumanity. Much patient work is need along this road towards the freedom and valorization of mankind.“
