Below is a quote from George Macdonald's There and Back. The context is England in the mid 1800's. A country parson (Mr. Wingfold) is tutoring a young woman (Barbara) who lives in his parish.
"Wingfold set himself to keep Barbara busy, giving her plenty to read and plenty of work... Among other things, he set her to teach his boy where she thought herself much to ignorant: he held, not only that to teach is the best way to learn, but that the imperfect are the best teachers of the imperfect... When a man, he said, agonized to get into other hearts the thing dear to his own, the false intellectual or even moral forms in which his ignorance and the crudity of his understanding compelled him to embody it, would not render its truth of none effect, but might, on the contrary, make its reception possible where a truer presentation would stick fast in the door-way."
We would all agree, I'm sure, that teaching is an invaluable way to learn. But what about the imperfect are the best teachers of the imperfect.
Question: In what sense can an imperfect teacher be the best teacher of an imperfect student? Is it a teacher who admits that they don't know it all, they don't have all the answers, but nevertheless they are willing to learn with their students?
