In my web of belief, my bathroom ghost sits somewhere liminal; he’s not part of how I typically navigate the world, which requires constant banal prediction. That it remains there, however, is ethically important. Your ghosts, too, your demons, your holy visions, don’t need to exist; you could no doubt account for them scientifically. The bombastic tendency of Western science is to pathologize, and thus to dismiss such things. But the question of what realities are possible should not just be answered by the measurable components of what already has been. Does maintaining the reality of your ghost hurt you or help you? Does a collective commitment to something mystical, outside “reason,” cause more harm than good? My bathroom ghost is a heuristic (again, not a metaphor) for considering what is desirable to allow in our worlds as opposed to that which we should explain away. Because even though I could explain him away, he will still come and scare me. So I might as well make epistemic room for him; it’s more interesting to do so.
