Those who have to educate to something higher must themselves have an idea of what they want. They must believe in the possibility of every mind and character to be lifted up to something better than it has already attained; they must themselves be striving for some higher excellence, and must believe and care deeply for the things they teach. For no one can be educated by maxim and precept; it is the life lived and the things loved and the ideals believed in by which we tell, one upon another.
