# Holes and Absences **Opening (not a real abstract):** Sam cannot thread a needle - he asks for help, saying that he doesn’t see the eye well enough. Mary is at the beach playing with sand. After making a hole, she says that she is going to fill it with water. Tom is approaching a tunnel and believes that it looks five hundred meters away. Ben looks at the net and wonders whether a fox enlarged a small hole in it and killed three chicks. There are all sorts of holes that we claim we see (or not see well enough) - splits, clefts, orifices, apertures, tunnels in mountains and eyes of needles. In justifying our claims, we make allegations about our visual impressions: it looks like there is hole of which we are visually aware, which can be filled, plugged, enlarged, searched, threaded... My question is this: what exactly do we see when our claim that we see a hole is true? **Authors:** [[Clotilda Calabi]]
