"The great men of that time agreed with Burke that petty thoughts go ill with a great empire, and that greatness in thought brings with it naturally some dignity of expression. On the famous occasion when Neville Chamberlain announced that ‘Hitler had missed the bus’, I happened to be listening with Granville Barker, and Barker murmured: ‘Asquith would never have said that’. Limehouse and Liverpool and post-war habits have accustomed us to a more colloquial idiom, which may be easier for an uneducated audience to follow, but does, I think, unconsciously lower the tone of thought."
