J.R.R. Tolkien, letter to Michael Tolkien (November 1, 1963):
The devotion to 'learning', as such and without reference to one's own repute, is a high and even in a sense spiritual vocation; and since it is 'high' it is inevitably lowered by false brethren, by tired brethren, by the desire for money, and by pride: the folk who say 'my subject' & do not mean the one I am humbly engaged in, but the subject I adorn, or have 'made my own'. Certainly this devotion is generally degraded and smirched in universities. But it is still there. And if you shut them down in disgust, it would perish from the land until they were re-established, again to fall into corruption in due course.
