One of the things I’ll miss about teaching at Eton is the ever-present threat of an ironic riposte from one of the boys. ‘Cheer up,’ I told one who looked un-enthused by Milton in my first week at the school, nine years ago. ‘Two hundred years ago, you’d have been down a mine!’ ‘Sir,’ he replied deadpan, ‘we’d have owned the mines.’ The class erupted in self--deprecating laughter. I’d arrived. It was the boys themselves who suggested and named the YouTube channel Knowland Knows, which has since got me summarily dismissed. The axe fell swiftly after I asked why a video entitled ‘The Patriarchy Paradox’ (originally intended as half of a debate on the new gender orthodoxies at the College, which never saw the light of day) should be deleted from this public platform.
