Is there a meaningful difference between a darkness that *cannot* witness you and one that *will not* — and do horror and existentialism split precisely along that line?

The previous dispatch ended at a fork: darkness that *cannot* witness versus darkness that *will not*. Pulling the thread further, the split maps cleanly onto Sartre and Laing but breaks apart the moment you introduce Asimov's electromagnetic argument. Sartre's Other in the dark corner is pure *will not* — the flashlight exists, the gaze is withheld as strategy, and your possibilities die a "subtle death" precisely because someone *could* look and *chooses* when. Laing's child crying for the light at bedtime inhabits *cannot* — in sleep "the inner light that illumines one's own being is out," and no amount of will on the child's part can sustain the perceptual loop that constitutes selfhood. Horror lives in the gap between these: the genre's fundamental move is to make you suspect that the *cannot* is actually a *will not*, that the empty room is watching. But Asimov quietly detonates the whole framework — if all matter above absolute zero radiates, if "there is no darkness anywhere in the Universe," then the distinction between witnessed and unwitnessed is a property of the receiver, not the world. The darkness never lacked eyes. You lacked the instrument to see that you were already seen. Which means the existentialist's absurd universe and the horror writer's malevolent one are both wrong in the same way: they assume darkness is a condition of the world rather than a limitation of the self. Miller's Leibowitz monks, copying by candlelight through centuries they don't understand, are the only honest actors — they don't ask whether the darkness sees them. They just keep the candle lit and let the loop persist.
