"To me, the circle and the square where the sky and the earth, as symbolized by the ancient Oriental religions; they formed a kind of rudimentary alphabet by means of which everything could be expressed with the most limited means. They evoked prehistoric runes and the early I-Ching, or Book of Changes."

The policy of letting the child 'do what he likes' is an insidious one, since the children are encouraged to continue always at their original superficial level, without receiving guidance in study. Furthermore, the 'three Rs,' the fundamental tools, are neglected as long as possible, with the result that the child's chance to develop his mind is greatly retarded. The policy of teaching words via pictures instead of by the alphabet tends to deprive the young child of the greatest reasoning tool of all.
