Epistemic vocabulary for product design

Status: owner-directed conceptual orientation, preserved under EM-0025.

This document records the conceptual territory behind Epistemedia's name and product direction. It

is not an authoritative history of philosophy, a normative ontology, an accepted evidence dossier,

or a homepage manifesto. Historical and philological claims need their own sourced review before

they are presented as knowledge objects.

Working product thesis

Epistemedia is not a larger container for statements. It is an attempt to preserve the architecture

by which information may earn the status of knowledge:

claims + evidence + provenance + dependence + counterevidence + uncertainty + revision

A page can say what has been written. An epistemic system should also make inspectable who asserted

it, from what evidence, through which method and inference, under what scope and policy, with what

defeaters, and how that state changed.

The foundational separation is:

world state ≠ epistemic state

Reality is not created by a dossier. A dossier represents what particular actors can responsibly

claim about reality from a declared evidence frontier.

A working layer map

| Layer | Question | Product treatment |

| --- | --- | --- |

| Ontology / world state | What exists or occurred? | Never silently equated with a current evaluation |

| Observation / data | What was measured, recorded, or experienced? | Bound to source, method, time, and edition |

| Information | What pattern or message was organized from data? | Preserved without automatic endorsement |

| Proposition / claim | What is being asserted about the world? | Separate from its speaker and current status |

| Evidence | What bears on the proposition? | Typed as support, rebuttal, qualification, defeat, or dependence |

| Belief / assertion | Who takes what stance, when, and on what basis? | Actor- and time-bound |

| Warrant / justification | Why is that stance responsibly held? | Made inspectable through sources, methods, and derivations |

| Knowledge / understanding | What is sufficiently grounded, and why? | Policy-relative, scoped, revisable, and never reduced to a truth flag |

| Action / judgment | What should someone do here? | Kept distinct from descriptive evidence evaluation |

| Wisdom | What ends, tradeoffs, and larger context matter? | Not inferred merely from possessing more claims |

This is a product map, not a canonical philosophical ladder.

The Greek conceptual cluster

Translations vary by author, period, and context. The following senses are working distinctions,

not one-to-one definitions.

| Term | Working sense | Why it matters here |

| --- | --- | --- |

| **Epistēmē** (ἐπιστήμη) | disciplined or systematic knowledge and understanding | The namesake standard: not merely storing a statement, but showing how and why it is warranted |

| **Doxa** (δόξα) | opinion, belief, or seeming | A belief can be true by luck; the system must not call every assertion knowledge |

| **Technē** (τέχνη) | craft, skill, or productive know-how | Knowing how to make or do something is not exhausted by propositional evidence |

| **Phronēsis** (φρόνησις) | practical judgment in a concrete situation | Evidence about what is the case does not automatically decide what should be done |

| **Sophia** (σοφία) | wisdom, especially concerning deeper principles | Accumulated information or even explanation is not automatically wisdom |

| **Nous** (νοῦς) | intellect or apprehension of first principles | Every derivation eventually exposes premises it does not derive internally |

| **Logos** (λόγος) | account, reason, explanation, argument, or discourse | A claim should be able to show an inspectable account of why it is asserted |

| **Alētheia** (ἀλήθεια) | truth, sometimes rendered as unconcealment | Truth and knowledge are different: what is true need not yet be known |

| **Gnōsis** (γνῶσις) | knowing, recognition, or acquaintance | Experiential acquaintance may not be interchangeable with systematic explanation |

| **Mathēsis** (μάθησις) | learning | The process by which an epistemic state changes deserves its own history |

| **Pistis** (πίστις) | trust, confidence, or faith | Testimony and institutional trust are real inputs whose warrant must remain visible |

| **Agnoia** (ἄγνοια) | ignorance or lack of knowledge | Missing knowledge is a representable condition, not a zero value |

| **Aporia** (ἀπορία) | puzzlement or impasse | A well-specified unresolved question is productive output |

| **Epochē** (ἐποχή) | suspension of judgment | Withholding evaluation differs from declaring a proposition false or merely missing |

| **Praxis** (πρᾶξις) | action or practice | The consequences of knowledge claims appear in action, but action has separate norms |

A useful but non-universal shorthand is doxa → epistēmē → sophia: opinion, grounded knowledge,

and wisdom. Aristotle's distinctions complicate any simple ladder by separating systematic

knowledge, craft, practical judgment, first-principle apprehension, and wisdom.

The sometimes-invoked image of epistēmē as knowledge one can “stand upon” is useful as a product

mnemonic, not a literal or sufficient etymological definition.

Historical senses to keep distinct

The name carries more than one intellectual history:

1. In ordinary ancient usage, epistēmē can cover knowledge, understanding, competence, or skill.

2. In a Platonic register, it is often contrasted with doxa: knowledge rather than opinion.

3. In an Aristotelian register, its strict form emphasizes structured explanatory understanding—

knowing why, through causes, principles, and demonstration.

4. In a Foucauldian register, an episteme is closer to the historically contingent background of

categories and rules that makes some knowledge claims intelligible in a period.

These senses are related but not interchangeable. The present application mainly uses the second

and third as inspiration. The Foucauldian sense remains a later design question: a sufficiently

rich system should be able to inspect the categories, authorities, and evidence standards that

made a claim expressible, not merely its supporting citations.

Modern operational vocabulary

| Concept | Operational question |

| --- | --- |

| Propositional knowledge | What is claimed to be the case? |

| Procedural knowledge | What can an actor reliably do? |

| Explanatory understanding | Why is it the case, and what dependencies produce it? |

| Epistemic status | What may be responsibly asserted at this frontier and under this policy? |

| Evidentiality | Was the basis observation, measurement, testimony, inference, simulation, or prediction? |

| Provenance | Where did this object come from, and how was it transformed? |

| Epistemic lineage | Which sources, data, prompts, methods, and derivations does it depend upon? |

| Warrant | What makes reliance on this belief responsible rather than lucky? |

| Defeater | What evidence or condition weakens or blocks that warrant? |

| Uncertainty | What remains unknown, variable, or underdetermined? |

| Epistemic uncertainty | What uncertainty comes from limited knowledge or model ignorance? |

| Aleatoric uncertainty | What variation is treated as irreducible under the model? |

| Epistemic modality | Is the claim necessary, probable, possible, apparent, or merely reported? |

| Fallibilism | How can a responsibly held claim remain open to revision? |

| Falsifiability | What observation would count against the claim? |

| Epistemic dependence | How much of the apparent agreement is copied testimony or shared infrastructure? |

| Hermeneutics | What interpretive choices shape the meaning assigned to a source? |

| Social epistemology | How do testimony, expertise, institutions, incentives, and communities create credibility? |

| Epistemic injustice | Whose testimony or interpretive resources are made illegible by the system's rules? |

Bayesian updating is one useful formal account of revision—prior, evidence, posterior—but it is not

the only legitimate representation and should not be fabricated where inputs cannot be defended.

Product requirements implied by the vocabulary

1. Separate world objects, propositions, assertions, evidence, derivations, and evaluations.

2. Never store truth or confidence as an intrinsic property of a proposition when it is actually a

policy-, actor-, time-, or frontier-relative evaluation.

3. Preserve exact provenance and lineage before counting apparent corroboration.

4. Record how a source supports a claim: direct observation, measurement, testimony, inference,

prediction, simulation, or interpretation.

5. Retain contradiction, counterevidence, negative results, defeaters, and supersession.

6. Represent unknown, unassessed, disputed, aporia, and suspension of judgment without

coercing them into false or zero.

7. Distinguish knowing-that, knowing-how, knowing-why, and deciding-what-to-do.

8. Make the process that generated a claim inspectable, especially for AI-generated information.

9. Preserve historical epistemic states so rational revision does not erase why an earlier belief

was once warranted.

10. Keep policy and conceptual framework visible: a projection is an account under declared rules,

not the world speaking without mediation.

What this does not authorize

This vocabulary does not add protocol fields, promote dossier keys into normative schemas, claim a

universal definition of knowledge, or make “what is episteme?” a How We Know case. It should guide

future models and editorial choices only through separately accepted tasks.

Future source packet

Before publishing a historical or philosophical treatment, independently retrieve and review a

bounded packet that may include lexicographic evidence, Plato on knowledge and opinion, Aristotle's

*Posterior Analytics* and *Nicomachean Ethics* VI, modern work on knowledge by acquaintance,

Gettier-style epistemic luck, social epistemology and epistemic injustice, fallibilism and

falsification, and Foucault's use of *episteme*. This list is a retrieval agenda, not a citation or

claim receipt.
