noting no thing is a collection of objects, ephemera & writings related to silence, gaps, ellipses and lapsus. To put it plainly, it’s a dedication to absence, or rather, to a former presence.
You can think about this another way: instead of silence preceding the speech that breaks it, silence is positively brought into the world through speaking, as a hole or absence that language can never abolish or “make speak,” but which forever twists and haunts that which is spoken. And one of the lessons of Kafka’s dog is that it’s from this void that one philosophizes. The dog turns silence into an object of investigation—the same silence that he is the living embodiment of.

Three frames were donated by Mertens frames. These frames formerly inhabited works of Jacqueline Mesmaeker.
Rather than pointing to objects existing in the world, evidence indicates or manifests an unseen[...]The art of subtraction is the art of evidencing of what is not.

Now the Sirens have a still more fatal weapon than their song, namely their silence. And though admittedly such a thing has never happened, still it is conceivable that someone might possibly have escaped from their singing; but from their silence certainly never. Against the feeling of having triumphed over them by one's own strength, and the consequent exaltation that bears down everything before it, no earthly powers can resist.
F. Kafka, The Silence of the Sirens
