Character formation cannot be taught. It comes from experience and not from explanation.
The real preparation for education is a study of one's self. The training of the teacher...is something far more than a learning of ideas. It includes the training of character; it is a preparation of the spirit.
A child's character develops in accordance with the obstacles he has encountered... or the freedom favoring his development that he has enjoyed.
By the age of three, the child has already laid down the foundations of his personality as a human being, and only then does he need the help of special scholastic influences. So great are the conquests he has made that one may well say: the child who goes to school at three is already a little man.
Happiness is not the whole aim of education. A man must be independent in his powers and character; able to work and assert his mastery over all that depends on him.
