About the Corpus

SDT is developed entirely outside the institutional academic framework. The corpus consists of fifteen papers spanning foundational metaphysics, philosophy of physics, philosophy of mind, and AI philosophy. Each paper is structured around the single ontological axiom:

Reality consists of distinctly differentiated structure.

The corpus is offered freely for academic engagement.

Versioning Policy

The SDT corpus exists in two layers, each serving a distinct purpose.

PhilArchive (canonical published versions) — Stable, dated, and citable. Each version has a permanent identifier that does not change. PhilArchive is the reference for academic citation.

This site (working versions) — The active development surface. Papers here may be revised, restructured, or replaced as the corpus matures. The site is where new versions are drafted and refined before being archived at PhilArchive.

Status labels used throughout the site

  • stable — Archived at PhilArchive. Suitable for citation.
  • working — Stable version on this site. Ready to read; may or may not yet be on PhilArchive.
  • draft — Active revision in progress. Content may change without notice.
  • planned — Forthcoming; not yet drafted.

Citation practice

When citing SDT in academic work, always cite the PhilArchive version with its specific version number and year. Do not cite this site as a primary source. If you need to refer to a draft or working version on this site (e.g., in correspondence), make the working-version status explicit.

Currently published

Additional papers will be archived at PhilArchive as they reach stable status. The site will retain working versions that may move ahead of PhilArchive between updates.

Contact for Academic Engagement

Discussion, critique, and collaboration are welcome. The author is particularly interested in dialogue with researchers working on:

  • Foundations of quantum mechanics (especially modal/possibilistic interpretations)
  • Philosophy of time (especially non-presentist process ontologies)
  • Causation theory (especially anti-reductionist frameworks)
  • Constructor theory and related modal-structural approaches
  • AI alignment foundations (especially modal-structural rather than probabilistic frameworks)

Please reach out via ORCID-listed contacts.
