What decent person would want to spend a life picking and cavilling? Picture this scene. A critic arrives at the gates of heaven. 'And what did you do?' asks Saint Peter. 'Well', says the dead soul. 'I criticised things'. 'I beg your pardon?' 'You know, other people wrote things, performed things, painted things and I said stuff like, "thin and unconvincing", "turgid and uninspired", "competent and serviceable,"... you know'.
