Where is the edge of this bottle?

Nowhere on the label. Out on the paper its lines are straight; where the bottle stands they swerve, crowd and break, as glass and a drink would make them. Zoom in as close as your screen will go: you will find lines that stop and lines that turn, and not one that traces the bottle.

The hidden shapes people love most take their edge from something else. The arrow in FedEx’s logo is the white between an E and an x. In one of Absolut’s ads the bottle is a swimming pool seen from above, its edge the pool’s own rim. Malika Favre’s label for Oe wine is a face cut out of paper, and the bottle’s dark glass, showing through the cut, becomes a second face.

Scientists draw shapes with no edge at all, Kanizsa’s triangle the best known, but in black wedges on white, to be studied. I wanted a shape with no edge on a thing you would want to hold. So I drew this label; it belongs to no brand.

Seven times closer, at the right shoulder, the edge comes apart.

Straight lines arrive from the paper and stop. Inside, the same lines, seen through the glass, run down the wall, crowded. Real glass would crowd them tighter still, until they blurred into grey, and a band of grey reads as an outline. So in the few places glass would press them together, like this wall, the label is not true to glass: it keeps its lines apart.

Lower, where the drink begins, every line breaks clean across, as a straw looks broken where it enters water. At the wall there, two small hooks: the drink climbing the glass, as it does in every glass you have filled.

You see the edge anyway because seeing comes in stages. An early stage reports lines. A later one looks for places where many lines turn or jump together, and reports an edge there as it would for a real one.

In monkeys the difference is stark. Faced with lines that only shift by half their spacing, 45 of the 103 cells recorded in the later stage reported an edge; of the 60 recorded in the early stage, one did. Vision scientists call such an edge an illusory contour; Kanizsa called it subjective.

It only works where lines cross the edge. An upright line beside the bottle’s upright side would never turn or jump, and that side would vanish; so every line here slants. The bends read as glass because that is how clear glass gives itself away: it warps whatever lies behind it.

And a bottle helps. A shape people know, standing upright, is picked out from its background more often than a shape they don’t.

There is no edge in the ink. The one you see is yours.
