Chapter 9 says children need an education of love before an education of knowledge. They are meant to learn reality inside a home where they can experience that God loves their parents, their parents love each other, and they themselves are held inside that circle.
This means the deepest form of education is not informational but relational. A child understands the moral and spiritual structure of the world first by living inside ordered love, not by mastering propositions.
The implication is pastoral as well as parental. When a community tries to educate only through content, it may produce informed people without forming hearts.
