We exist in the reality of evolution, tectonic plates, and relativity. And we live in a larger world than that. We live in a world of wonder and beauty, in a world of Bach and Emily Dickinson, in a world where we glory at a sunrise. We live in a world where we feel compassion and commitment for people and causes far beyond our immediate concerns. Is wonder simply an evolutionary advantage, or is there something more? If there is, do we know what it is?
