In one of Bill Watterson’s classic “Calvin and Hobbes” comic strips, his two protagonists walk through a field engaged in conversation. The ever-curious Calvin tells Hobbes that sometimes when he’s talking, his words can’t keep up with his thoughts. Calvin finds this strange, and wonders why we think so much faster than we speak. Hobbes delivers a characteristically philosophical retort, musing, “Probably so we can think twice.” The exchange perfectly captures their dynamic: Calvin’s somewhat childlike observation followed by Hobbes’ sage response. It’s a reminder to us all that it’s sometimes best to hold our tongue until we’ve fully thought things through.
