Does Happiness Write White?

Everyone's talking about happiness: politicians want to measure it, and self-help books explaining how to become ever happier are two-a-penny.

So why have literary folk been reluctant to depict this emotion, when many philosophers and politicians see it as the very point of human existence?

The French poet Montherlant may have the answer- he claimed that 'Happiness writes white', that it is too boring to depict or even unrepresentable.

Catherine Blyth explores the challenges facing award-winning writers when they try to put something as elusive and subjective as 'happiness' onto the page.

These include:

* Author, Helen Simpson
* Novelist, Ann Patchett
* Poet, Don Paterson

Producer: Faith Lawrence.
