reveals an idea latent in the idea of the seen. An optic anti-form, shadow shapes unseenness into a law of shadow’s nature and imposes its code moment by moment upon the territories that it has separated from light. The new regime is named dark, and within its boundaries hands can no longer be seen in front of faces. Under dark’s restrictive new law, the clock and its own hands and face have been replaced by an unseen, unthought metaphor.

Seen and thought, then: beakshadow and capacious birdbrain.
