”...I begin with a preliminary to the successful education of children, namely that husband and wife ought to be entirely one upon this subject, not only agreed as to end, but as to the means to be used, and the plan to be followed in order to attain it...However, I content myself with repeating, that certainly husband and wife ought to conspire and cooperate in everything relating to the education of their children; and if their opinions happen, in any particular, to be different they ought to examine and settle the matter privately by themselves, that not the least opposition may appear either to children or servants. When this is the case every thing is enforced by a double authority, and recommended by a double example; but when it is otherwise the pains taken are commonly more than lost, not being able to do any good, and certainly producing very much evil.”
