We have not yet discussed the spiritual dimension of the lowly pothole. It is not something, but a lack of something, a void, an absence, an emptiness.
They certainly seem also to be kenotic, from the Greek, kenosis (κένωσις), meaning self-emptying, as in the theological choice to become entirely receptive, a vessel waiting to be filled with perfection. Hot, black, gooey perfection.
Is the homophonic coincidence between 'holy' and 'holey' merely that? Or can we read something more into 'holy's' Old English origins meaning that "which must be preserved whole or intact" and related to the word for health and happiness.
