Maria Montessori said...
"There is a part of a child's soul that has always been unknown but which must be known. With a spirit of sacrifice and enthusiasm we must go in search like those who travel to foreign lands and tear up mountains in their search for hidden gold. This is what the adults must do who seeks the unknown factor that lies hidden in the depths of a child's soul. This is a labor in which all must share, without distinction of nation, race, or social standing since it means the bringing forth of an indispensable element for the moral progress of mankind."
