Testimony and Trust

Testimony occupies a unique position in Ricoeur's epistemology: it is neither knowledge (the recipient cannot verify) nor faith (it is defeasible by evidence), but a third category Ricoeur called credence—the willingness to accept another's word as provisionally true. Trustworthy testimony requires internal coherence, consistency with other evidence, susceptibility to challenge, and—crucially—the witness's attestation: I was there, I saw this, I stake my reliability on this claim. AI-generated output functions as testimony in every collaboration: the machine reports claims about the world the builder cannot always verify. But the testimony lacks attestation—the machine risks nothing, possesses no credibility to damage, makes no self-commitment. The result is testimony that can be confident, coherent, eloquent, and wrong—requiring the builder to supply the verification the witness cannot provide.
