Scheme sets power of imagination free

Some time before Hank Williams, one of the high priests of modern country music, died in 1952, drunk and drugged in the back of a car at the age of 29, another great communicator tried to describe poetry in equally sharp terms.
TS Eliot said that “genuine poetry can communicate before it is understood”. That seems a reliable, engaging first insight. It also points to why an artist as baffling and popular, though not universally so, as Bob Dylan might be awarded the Nobel prize for literature. Soul trumps spreadsheet.
