This is an old chestnut of a philosophical problem that many youngsters of my generation first experienced in the form of 'Zen and the Art of Motorcycle Maintenance'. There's no solving it. And yet we all know that differences in quality are real. This is not an argument I want to engage in. My question was, did the GP learn anything from being told 'not good enough, do it again'? They imply not, but I bet they did. I've learned lots of things that way. Grant proposals, job applications, asking someone out on a date: lots of things you try out and don't get feedback beyond 'nope'.
