Assumption

Provisional truth

Definition

Mechanism

A gap-filler used when Datum is missing; treated as true temporarily to allow thinking to proceed. Must be tracked and validated.

Invariants

  1. Provisionality: must be explicitly flagged as unverified.
  2. Tracking: must name what it stands in for — a missing Datum, or a judgment not made.
  3. Discharge: must carry a validation deadline or an invalidation trigger.

Risks

Failure modes

  1. Calcified

    depended on far downstream from where it was made, with nothing prompting a re-check.

  2. Mutually inconsistent set

    two assumptions each close a local gap and contradict each other in the same chain.

  3. Judgment recorded as datum-gap

    the premise replaces a decision nobody made rather than a fact nobody has, so validating it has no target.

A conclusion inherits the verification assurance of its weakest load-bearing premise.

A judgment kept after its reasons are lost is held as an assumption until the reasons are restored
