As one president’s term ends and another begins, there is a ceremony. Its importance is one of symbolism rather than substance. The Constitution is clear: On Jan. 20, there will be a transfer of power. There is no mention of an inauguration.
By definition, ritual acts have no direct effect on the world. A ceremonial event is one that symbolically affirms something that happens by other, more direct means. In this case, the election – not the inauguration – makes the president, although an oath is required before exercising his power.
Nonetheless, ceremonies matter. Having spent two decades studying ritual, I can attest to that. So can the recent history of inaugurations: In 2009, Barack Obama misplaced one word when reciting the presidential oath of office. As a result, he decided to retake the oath the next day. And in 2017, Donald Trump insisted that his inauguration was attended by a record-setting crowd, even as everyone’s eyes saw otherwise. He saw the size of the attendance as a measure of his legitimacy.
