Seamus Heaney: no shuffling or cutting — just turning over aces

The impersonator — Rory Bremner, Steve Coogan — speaks, in different voices, to a single primitive pleasure centre in his audience. Counterintuitively, we like the imposition of imposture. We connive at deceit, at replication, for the release of neurotransmitters, the flood of endorphins — the brandies of the brain. I once heard Peter Ustinov on a chat show replicate the sound of an electric bell being pressed. Pleasure on a different, even more vertiginous level. The audience was convulsed.

Unless a poet can produce this ungainsayable instant delight in the reader, this drench of dopamine, the poetry is automatically of the second order. (We expect less of our novelists, though great prose writers, such as Joyce or Dickens or Kipling, can also do it at will: Major Bagstock has a ‘complexion like a Stilton cheese, and… eyes like a prawn’s’; Mrs Podsnap has ‘nostrils like a rocking-horse’; Kipling gives us ‘the sticky pull of… slow-rending oilskin’; Joyce has the iron rim of a wheel ‘harshing’ against the kerbstone.)
