So just to start us off, can you give us a quick summary of the main argument that you make in that book?

Uh, sure.

The argument is essentially that imagination develops, that it's not something we are born with as a full-fledged trait.

There is a popular view of imagination that children are the most imaginative beings on the planet, and that with education particularly, like job training, adults lose their ability to be imaginative because we hone our skills at doing things that are very mundane and boring.

And children have this innate capacity that we no longer know how to use when we're adults.

But I argue that it's actually the opposite, that imagination is a skill that develops just like any other cognitive skill, and really what pushes that development is knowledge and reflection.

So the more you know, the more possibilities you can consider just beyond what you know.
