Metaphor (and its close sibling, the simile) tends to work on the page in one of two ways. Take this example, from Michael Cunningham’s A Home at the End of the World: ‘She washed old plastic bags and hung them on the line to dry, a string of thrifty tame jellyfish floating in the sun.’ This metaphor works principally by opening an information gap.

‘show not tell’. As C. S. Lewis implored a young writer in 1956, ‘instead of telling us a thing was “terrible”, describe it so that we’ll be terrified. Don’t say it was “delightful”; make us say “delightful” when we’ve read the description.’ The abstract information contained in adjectives such as ‘terrible’ and ‘delightful’ is thin gruel for the

In Gone with the Wind, Margaret Mitchell uses metaphor to make not a visual point, but a conceptual one: ‘The very mystery of him excited her curiosity like a door that had neither lock nor key.’

In his pioneering classic The Uses of Enchantment the psychoanalyst Professor Bruno Bettelheim argues that making sense of such terrifying transformations is a core function of fairytales. A child can’t consciously accept that an overwhelming mood of anger may make him ‘wish to destroy those on whom he depends for his existence. To understand this

Some researchers believe grandparents came to perform a vital role in such tribes: elders told different kinds of stories – about ancestor heroes, exciting quests and spirits and magic – that helped children to navigate their physical, spiritual and moral worlds. It’s from these stories that complex human culture emerged.

well-imagined characters always have theories about the minds of other characters and – because this is drama – those theories will often be wrong. This wrongness will lead to unexpected consequences and yet more drama. The influential post-war director Alexander Mackendrick writes, ‘I start by asking: What does A think B is thinking about A? It

Immersive model worlds can also be summoned by the evocation of the senses. Touches, tastes, scents and sounds can be recreated in the brains of readers as the neural networks associated with these sensations become activated when they see the right words.

The influential post-war director Alexander Mackendrick writes, ‘I start by asking: What does A think B is thinking about A? It sounds complicated (and it is) but this is the very essence of giving some density to a character and, in turn, a scene.’

Still, today, modern nations are principally defined by the stories we tell about our collective selves:
