Cognition under
finite conditions.
What can we justifiably claim about the world and ourselves?
The Epistemic Reality Project investigates the presuppositions and limits of our descriptions. It connects epistemic critique with the development of distinctions and rules for testing, intended to help us use, limit, and revise beliefs and models appropriately.

An introduction to the project
Current core paper October 2026
Model Management under
Finite Conditions
A Diagnostic and Decision Architecture
for Validity, Friction, and Revision
The current reference point for the project: an architecture for testing and managing stabilized orders and models across everyday, scientific, technical, and institutional contexts of cognition.
It separates assessments of validity from decisions about continued use and structures the justification of revision.
A programmatic contribution. The architecture supplements disciplinary procedures; its practical utility remains to be independently tested.
The project
Support orientation.
Keep correction open.
We organize experience, form expectations and guide our actions without fully surveying our own presuppositions and consequences.
ERP connects the investigation of these conditions with distinctions and rules for testing. It asks both what our descriptions allow us to claim and how we can use, correct or limit convictions and models appropriately.
These questions also concern our understanding of the world and ourselves: what follows from an explanation, and where do its claims end? This matters in everyday life and shared understanding, as well as in science, technology and institutions.

The project texts document different stages of development. The current core paper consolidates the present approach to epistemic and model management; earlier works remain available as individual contributions and as a record of the project’s development.
