We are special in the sense that we can know our place in the cosmos. We can know our place in space. We are at least one of the cosmos's ways of knowing itself. That fills me with reverence and joy. Another insight I really want people to consider is this: everyone has gotten this far. Everyone you meet has made it this far. Nobody is superior to anyone else from an evolutionary standpoint.
