A child's character develops in accordance with the obstacles he has encountered... or the freedom favoring his development that he has enjoyed.
Maria Montessori... the first thing his education demands is the provision of an environment in which he can develop the powers given him by nature. This does not mean just to amuse him and let him do what he likes. But it does mean that we have to adjust our minds to doing a work of collaboration with nature, to being obedient to one of her laws, the law which decrees that development comes from environmental experience.
