Below follows an interesting excerpt from the Seed  magazine interview with Alison Gopnik, author of the new book  The Philosophical Baby. The interview takes a look at children and imagination, and the meaning it has for the adult world.

 Seed: You describe children as being “useless on purpose.” What do you mean by that?

AG: It’s related to one of the basic things that came out of our research: Why do children exist at all? It doesn’t make tremendous evolutionary sense to have these creatures that can’t even keep themselves alive and require an enormous investment of time on the part of adults. That period of dependence is longer for us than it is for any other species, and historically that period has become longer and longer.

The evolutionary answer seems to be that there is a tradeoff between the ability to learn and imagine — which is our great evolutionary advantage as a species — and our ability to apply what we’ve learned and put it to use. So one of the ideas in the book is that children are like the R&D department of the human species. They’re the ones who are always learning about the world. But if you’re always learning, imagining, and finding out, you need a kind of freedom that you don’t have if you’re actually making things happen in the world. And when you’re making things happen, it helps if those actions are based on all of the things you have learned and imagined. The way that evolution seems to have solved this problem is by giving us this period of childhood where we don’t have to do anything, where we are completely useless. We’re free to explore the physical world, as well as possible worlds through imaginative play. And when we’re adults, we can use that information to actually change the world.

Seed: You think Freud’s and Piaget’s conceptions of young children’s theory of mind are wrong. What do we know that they didn’t?

AG: Both Piaget and Freud thought that the reason children produced so much fantastic, unreal play was that they couldn’t tell the difference between imagination and reality. But a lot of the more recent work in children’s theory of mind has shown quite the contrary. Children have a very good idea of how to distinguish between fantasies and realities. It’s just they are equally interested in exploring both. The picture we used to have of children was that they spent all of this time doing pretend play because they had these very limited minds, but in fact what we’ve now discovered is that children have more powerful learning abilities than we do as adults. A lot of their characteristic traits, like their pretend play, are signs of how powerful their imaginative abilities are.
