There is no description, no image in any book that is capable of replacing the sight of real trees, and all of the life to be found around them in a real forest.
Maria MontessoriThe task of the educator lies in seeing that the child does not confound good with immobility, and evil with activity, as often happens in old-time discipline . . . A room in which all the children move about usefully, intelligently, and voluntarily, without committing any rough or rude act, would seem to me a classroom very well disciplined indeed.
