“Michael Smithson, a social scientist at Australian National University who co-taught an online course on ignorance this summer, uses this analogy: The larger the island of knowledge grows, the longer the shoreline — where knowledge meets ignorance — extends. The more we know, the more we can ask. Questions don’t give way to answers so much as the two proliferate together. Answers breed questions. Curiosity isn’t merely a static disposition but rather a passion of the mind that is ceaselessly earned and nurtured.”
