Is beauty a reminder of something we once knew, with poetry one of its vehicles? Does it give us a brief vision of that 'rarely glimpsed bright face behind/ the apparency of things'? Here, I suppose, we ought to try the impossible task of defining poetry. No one definition will do. But I must admit to a liking for the words of Thomas Fuller, who said: 'Poetry is a dangerous honey. I advise thee only to taste it with the Tip of thy finger and not to live upon it. If thou do'st, it will disorder thy Head and give thee dangerous Vertigos.
