JOHN CHANDOS introduces extracts from a 17th-century controversy about freedom and authority between two Cambridge dons, ANTHONY TUCKNEY , Master of St John 's, and a former pupil of his, BENJAMIN WHICHCOTE , Provost of Trinity College and Vice-chancellor of the University. Their dialogue lays bare many of the recurring arguments in the debate between establishment ideas and the reforming intelligence. Readers: GARY WATSON and ALAN WHEATLEY
