Famous quotes containing the word spontaneous:
“If an educational act is to be efficacious, it will be only that one which tends to help toward the complete unfolding of life. To be thus helpful it is necessary rigorously to avoid the arrest of spontaneous movements and the imposition of arbitrary tasks.”
—Maria Montessori (1870–1952)
