"If in an educational approach one takes the child as a guide, it is obvious that the educator is led by the child instead of by preconceptions and prejudices. In fact it is the child himself who will be the guide of education."

"The preparation of the Spirit of the teacher is a vital part of our method, much more important than Explanation of the material. ...we must take upon ourselves the mission of bettering the condition of education. The main task is not to learn the method, but to open a new and better way of life for the child."
