The Cell Does Not Belong to the Organism

This conceptual paper examines whether organismal integration should be conflated with ontological possession of cells. It proposes that a cell may be materially contained within, functionally dependent on, and developmentally constrained by an organism while retaining a biologically bounded possibility-space not exhausted by its current organismal role. The paper introduces three terms: cellular episode, basal cellular autonomy, and inter-scalar dissociation. Fertilisation, reprogramming, evolutionary transitions in individuality, synthetic multicellular constructs, tumour microenvironment research, and context-dependent malignant phenotype are used as convergent constraints rather than as proof of a new ontology. Cancer is framed as a possible reconfiguration of the relation between cellular autonomy and organismal integration, not simply the acquisition of autonomy. This version records a conceptual baseline reached on 27 July 2026 before systematic study of Michael Levin’s theoretical corpus.Version note: Version 1.0 is intentionally frozen as the pre-Levin conceptual baseline. Any subsequent comparison with Michael Levin’s theoretical corpus will be published separately, without altering the provenance statement preserved in this record.
