Jiddu Krishnamurti:

To raise a child sanely, to help him to be perceptive so that he sees through these stupid prejudices, we have to be in close relationship with him. We have to talk things over and let him listen to intelligent conversation; we have to encourage the spirit of inquiry and discontent which is already in him, thereby helping him to discover for himself what is true and what is false. It is constant inquiry, true dissatisfaction, that brings creative intelligence; but to keep inquiry and discontent awake is extremely arduous, and most people do not want their children to have this kind of intelligence, for it is very uncomfortable to live with someone who is constantly questioning accepted values.
