Degrees of Confidence: Speaking about Knowledge without Absolute Claims

State what is established, its grounds, and what remains open. Strong feeling does not replace checking, a number does not create measurement, and a decision does not establish the future.

Questions explored

Must every checked detail be softened?

No. State its subject and grounds definitely while preserving limits on a broader conclusion.

Does a precise percentage always improve reliability?

No. Explain what it represents and how it was obtained; without calculation, do not imply measurement.

Can a report change while remaining conscientious?

Yes. Identify new grounds, changed circumstances, or a specific earlier error; retain what remains established.

Key distinctions

Peirce distinguishes a belief’s settlement from its truth. (Fixation of Belief III–IV; philosophical reasoning.)

Hume X.87 relates conviction’s strength to evidence. (Historical experience context, not a ready statistical formula.)

Locke considers probable assent separately from certain knowledge. (Essay IV.XV and XVI’s opening; historical epistemological terms.)

The article distinguishes established information, inference, desire, decision, and promised work. (Original everyday illustrations and voluntary exercise.)

Limits of interpretation

  • Philosophical application of bounded historical texts, not clinical calibration, a universal probability scale, or a forecasting calculation. Numerical illustration invented. Preserve facts, inference, desire, decision, promises, and grounds adequate for a particular action as distinct.
