The impossibility of self-evidence extends to any boundary the agent might posit, not only the self-environment boundary

Entities in the same semantic neighborhood but without a typed relation to this one — candidates for new edges or unrecognized duplicates.

• One dimension of self-evidencing is provably impossible: evidencing the boundary that would constitute the agent as an entity separate from their environment.claim0.830
  Central thesis of the paper.
• Subjectively therefore, there can be no evidence for a self separate from the world.claim0.824
  Subjective corollary of the boundary unmeasurability claim.
• There is no self-evidencequote0.818
  Title of the paper, encapsulating its central claim.
• Subjectively, there can be no evidence for a self separate from the world.claim0.816
  Translates the formal impossibility into phenomenological terms.
• "The boundary is the medium through which all evidence flows, but it is not itself evidenceable."quote0.815
  Pithy statement of the core impossibility result in its first-person experiential implication
• no evidence for a self separate from the world.quote0.805
  Key takeaway from the argument.
• No finite agent can obtain evidence for its own separability from its environmentclaim0.800
  Core claim of the paper; derives from Corollary 3.1 of Fields & Glazebrook (2023)
• Any system that persists must minimise surprisal, thereby gathering evidence for its own generative model, a process known as self-evidencing.claim0.797
  Foundational claim of the paper, defining self-evidencing.
