Via MindBlog, Alison Gopnik reflects on why children spend so much time thinking up imaginary worlds. Starting out from the notion that we are seeking an accurate picture of the world, fiction and imagination (and, one could add, critique) become puzzling problems to be explained. A slight shift of emphasis frames the question very differently:
The greatest success of cognitive science has been our account of the visual system. There’s a world out there sending information to our eyes, and our brains are beautifully designed to recover the nature of that world from that information. I’ve always thought that science, and children’s learning, worked the same way. Fundamental capacities for causal inference and learning let scientists, and children, get an accurate picture of the world around them – a theory. Cognition was the way we got the world into our minds…
I still think that we’re designed to find out about the world, but that’s not our most important gift. For human beings the really important evolutionary advantage is our ability to create new worlds. Look around the room you’re sitting in. Every object in that room – the right angle table, the book, the paper, the computer screen, the ceramic cup was once imaginary. Not a thing in the room existed in the pleistocene. Every one of them started out as an imaginary fantasy in someone’s mind. And that’s even more true of people – all the things I am, a scientist, a philosopher, an atheist, a feminist, all those kinds of people started out as imaginary ideas too. I’m not making some relativist post-modern point here, right now the computer and the cup and the scientist and the feminist are as real as anything can be. But that’s just what our human minds do best – take the imaginary and make it real. I think now that cognition is also a way we impose our minds on the world.
In fact, I think now that the two abilities – finding the truth about the world and creating new worlds – are two sides of the same coins. Theories, in science or childhood, don’t just tell us what’s true – they tell us what’s possible, and they tell us how to get to those possibilities from where we are now. When children learn and when they pretend they use their knowledge of the world to create new possibilities. So do we whether we are doing science or writing novels. I don’t think anymore that Science and Fiction are just both Good Things that complement each other. I think they are, quite literally, the same thing.
