You, alone with yourself — the one you can never leave, never fully see, and never quite trust is real. A sphere of UD0's ERĒMIA domain (ἐρημία, solitude) — walking the three prisons of perception: Plato's Cave, Foucault's Panopticon, and the Simulation.
each facet emerges by one of four natures
Phase A the Cave · Phase B the Panopticon · Phase C the Simulation
Alone, you face the wall and take the shadows for the world — Plato's allegory (Republic, Book VII). The first prison is perception itself: you have only ever seen your own projections, and called them real.
Foucault's lesson (Discipline and Punish, 1975): a prisoner who might always be watched begins to watch himself. So does the self — it installs the guard inside, and is never alone, and never not-alone, again.
The final doubt: Descartes' demon, the brain in a vat, Bostrom's simulation argument (2003). If the world might be authored, the one thing left is the doubting itself — and even that is alone.
