 Well, it's kind of an experiment in cognitive cooking. What you're trying to do is bring really different ideas together and see whether it clarifies an otherwise very complicated situation. Because when you try to bring together experimental science and classical studies and historical studies and archaeological studies, you're, I think, entering into a new sort of dialogue. Because most disciplines have remained in their little, narrow worlds for a very long time and find it very difficult to get out of what's called a silo, a sort of very confined space into a wider viewpoint. And we're all trying to build a wider worldview. That's the simplest way of looking at it. My approach has been to try to build a mind, taking into account the contribution of culture and brain. So I started with the Myocene apes, our distant ancestors, and I built systematically on the basis of all of the different kinds of evidence you can find, the components of the modern mind. That was a book about 25 years ago called Origins of the Modern Mind, and I've been articulating that idea ever since. So what you do is you look at the interrelationships between different mental abilities in building a culture first, and then in monitoring how that culture and its technologies changed the brain, changed the direction of evolution, and in turn the brain changed and that changed the nature of the cultures, which can turn feedback onto the brain evolution until we reach the modern period of about 150,000 years ago, when cultural evolution more or less took over. There may have been some small changes to the brain since then, but basically we've been living with cognition, the mind that's being on a platform of the brain, but really built by cultural change. One of the things I like a lot is that the humanists have obviously been influenced by the contributions from the cognitive side, and I'm hoping that the cognitive scientists will also learn something from the humanists because that's something I've emphasized in my work, and I really think that's important.
