Gładziejewski (2025), Synthese 206:225, LIT-1360, read in full in NOTE-1056: §4.1 (pp. 15–17) and footnote 10, on the ground of §2’s equation of predictive processing with compression.
What was actually shown
An argument, no data:
- The pattern. Some sensory regularities are endogenous: touch from typing, vision from one’s own eye movements, interoceptive hunger. “the self is inferred and represented as a common, single cause that underlies certain (endogenously generated) regularities in the sensory signal” (p. 16). The model “achieves compression by positing a single, stable entity as the common cause of many endogenous patterns” (p. 16). At fast timescales this is the minimal self; at slow ones, the narrative self.
- No further fact. Swap two cells between two gliders in the Game of Life and the game runs on. Which glider is which has “no further fact within the GoL ‘world’” to settle it (p. 17). Parfit’s argument for persons has the same form.
- The verdict. Anti-realism about selves-as-substances and realism about selves-as-patterns are compatible. “The conflict between those positions is apparent, and arises at a meta-level discussion about which criteria of reality are more reasonable to use for this particular domain” (p. 17).
- Footnote 10. The self is partly self-constituted, “a sort of self-fulfilling prophecy”, because active inference brings behaviour into line with the self-model. In some dissociative states the patterns may be “better compressed by model that posits two or more narrative selves residing within one body”.
What could come out otherwise is the compression claim: a single self-cause might not compress the data better than a model without one. The paper does not test it.
What this does not say
- It does not say the self-model misrepresents. A posited common cause is a lossy compression, and the paper calls the self “as real as any real pattern” (p. 17) under deflated criteria. The exchange that filed the work described it as treating the self as a real pattern “whose representation can exaggerate its unity”. The paper does not say that.
- It is not about experience. The minimal self “is experienced as” the sense of being an embodied agent (p. 16), but nothing is claimed about whether or why the pattern is felt.
- It does not say what makes a self-model a self, rather than one more posited cause among the agent’s models.
- It is not about collectives. The self here is one organism’s model of its own sensory effects.
- The compression is asserted, not computed. It rests on the cited predictive-processing accounts, and on §2’s analogy between free energy and description length.
Connections
- CLAIM-355. The account supports the claim’s structure: the binding pattern is real, and the single substantial owner is the content of a model. It also presses the objection CLAIM-355 names from Drayson. If the single owner is just how the pattern compresses, then a self-model that presents one owner is lossy, not false. CLAIM-355 already says it survives only where a misdescription is shown, and footnote 10 gives a candidate: a case where one self-cause compresses worse than two.
- THEORY-064 and THEORY-691. Metzinger’s self-model and Dennett’s centre of narrative gravity. This adds a mechanism, compression of endogenous signals. Of THEORY-064’s “nothing beyond such models is a self”, it says that whether that is anti-realism is a matter of criteria.
- THEORY-563. The same compression criterion, applied to the self and not to consciousness.
- THEORY-877. The structural account of manifest content filed from the same paper. The self is one of its cases.
