Dorothy Sayers's famous speech at Oxford University "The Lost Tools of Learning"
That I, whose experience of teaching is extremely limited, should presume to discuss education is a matter, surely, that calls for no apology. It is a kind of behavior to which the present climate of opinion is wholly favorable. Bishops air their opinions about economics; biologists, about metaphysics; inorganic chemists, about theology; the most irrelevant people are appointed to highly technical ministries; and plain, blunt men write to the papers to say that Epstein and Picasso do not know how to draw. Up to a certain point, and provided the criticisms are made with a reasonable modesty, these activities are commendable. Too much specialization is not a good thing.
