The parent, the person in charge of education
In the case of comparative poverty, which is the common lot of mankind, we come back to a general parental responsibility, which is the common sense of mankind. We also come back to the parent as the person in charge of education . . . . Private education really is universal. Public education can be comparatively narrow. The mother dealing with her own daughters in her own home does literally have to deal with all sides of a single human soul.
