The robe, a visual cue signaling status and importance, is part of the ritual thing. And we need rituals because rituals make our values tangible. You can’t think your way toward valuing something. You have to live it. You have to experience it. And one way of making it easier for others to live and experience a value is to make up cute outfits for them to wear and important-sounding words for them to say—in short, to give them rituals. Rituals are visual and experiential representations of what we deem important. That’s why every good religion has them.
