"I don’t find our relative insignificance disheartening at all: The main thing it tells me is that in a culture that worships celebrity and the purportedly extraordinary, all people are ordinary people. All people have the same responsibilities to themselves and to each other. Maybe the universe cares nothing for us, but we care about each other. And most encouragingly, we care not just for our friends or family but for the whole enterprise of life—we care about strangers and about humpback whales and, most beautifully of all, we care about the dead. We try with our lives to honor theirs. That’s how we make our lives meaningful, and how we make their lives meaningful, too."
