In this chapter of, The Brain Rules, Medina speaks about the untainted mind of a newly-born child. He speaks of the natural feeling we get to want to explore something. As a baby, we love to touch everything and taste anything, this is because we have an instinct to explore. Even while we grow up we still like to explore new things which is why when we get hurt by something we learn to avoid that which hurt us. This explains the natural instinct to always try something new, because you want to experience it for yourself.
