Jack Upland, Friar Daw's Reply, and Upland's Rejoinder.
Edited by P.L. Heyworth (Oxford: Oxford University Press, 1968), pp. 52-53 (from the editor's Introduction):
It remains to be said that the modest interest of these texts is that of a footnote to a historical controversy. In five hundred years they have received barely a dozen pages of desultory academic discussion scattered over as many books, and it is to their credit that they cannot claim a single learned article to themselves. They have earned their neglect. If I tidy them away to an honest grave it is not with any claim to 'definitiveness', but because there is no good reason why they should ever be disinterred again.
