Of all human relationships, perhaps none evokes more awe than the one we have with our own existence, otherwise known as the self. Remarkably, through a lifetime of social interaction, each of us becomes an entity that is both similar to and dierent from all others. For this journey, humans have long found support and inspiration in diverse sources, from religion to poetry to science. In the twenty-rst century, service to the self is also plentiful in museums.
