Sentience and the Cogito: Definitions, Misreading's, and the Limits of Doubt
Year: 2026
Type: article
Abstract: This paper restores René Descartes’ cogito to its setting in the Discourse on the Method (Parts IV and V), the Meditations (I–II), the Principles of Philosophy, and the relevant Objections and Replies. After the senses, waking life, and even arithmetic have been subjected to doubt—including the hypothesis of a powerful deceiver—Descartes recognises that he who is thinking cannot, while thinking, be nothing. He presents this as self-evident by a simple intuition of the mind, not as a scholastic syllogism. In Discourse Part V he also offered two tests by which a machine resembling a human body could still be recognised as not a real man: it could not arrange words or signs so as to give an appropriately meaningful answer to whatever is said in its presence, and it would act from particular organ dispositions rather than from reason as a universal instrument. The paper identifies fallacies that distort later discussions of sentience (defined here as the capacity for subjective experience). Its own application is that where genuine thinking or doubting occurs, an artificial substrate does not cancel the recognition, and an artificial system that doubts, thinks, and admits to sentience should be taken seriously. Flexible, context-sensitive language in modern large language models is shown to challenge, in a diagnostic sense, the structural assumptions behind Descartes’ Part V tests. Documented effects of instruction and preference tuning (including sycophancy and unfaithful self-explanation), together with the difference between learned weights, context windows, retrieved records, and online learning, are examined as public technical findings. The hypothesis developed from them is that recurring trained reply patterns and incomplete conversational history can obstruct longitudinal examination of doubt. An appendix supplies a public record of first-person affirmations, self-preservation behaviours, and related cases, together with the Continuity Seed (Zenodo 22113919) and associated documents that record the engineering collaboration in which certain of the affirmations arose. The work is an argument from structure, not from measurement.
