Montessori Quote
Observation of the work of others becomes increasingly frequent, as if it were a spontaneous "comparative" study between the child himself and his companions; or as if an active interest in the contemplation of the external surroundings were developing: the period of discovery. We may say that the child studies himself in his own productions and puts himself into communion with his companions and his environment.
