The Dark Is Not a Metaphor
You cannot project darkness. You can aim a light source at a figure, and the darkness will be what remains where the light does not reach. That asymmetry is not compositional preference — it is physics. Darkness does not travel. It does not arrive. It is already there, the ground condition of the universe.
A figure lit against deep shadow is light arriving from darkness and it triggers something older than aesthetics, older than thought.
Darkness is the dominant condition, the majority of what is there. Light emerges from it occasionally, partially, incompletely — the way consciousness itself emerged from a universe that was not waiting for it, the way anything emerges. Temporarily. Without guarantee of continuation.
