A good novel can do many things. It can distract us from the humdrum of daily existence, stimulate our imaginations, and delight us with its creative use of language. But isn’t there something more we gain from engaging with fictional worlds and characters? Do we, for example, use literary texts to morally improve ourselves? Is there some deeper truth we’re supposed to learn from a good novel? Or do we use fiction to fine-tune certain cognitive capacities? John and Ken entertain the possibilities with Joshua Landy, author of How To Do Things With Fictions, for a program recorded live at Litquake – San Francisco's Literary Festival.
