Maria Montessori wrote extensively throughout her life capturing and propelling the substance of her evolving work for generations to come.
“We thus began to communicate with each other through written language; and this proved to be most interesting to the children. They gradually discovered the wonderful property of writing, that it transmits thought. When I began to write, they trembled in their eagerness to know what I had in mind and to understand it without pronouncing a single word. Written language does not indeed need speech. Its whole grandeur is only understood when it is completely isolated from the spoken word.”
