The claim that the French revolutionaries abolished the *système de preuve légale* *because* its *a priori* rules had come to seem epistemically untenable ([[claim-french-revolution-abolished-preuve-legale-for-intime-conviction]]) is accurate but, on R. G. Bloemberg's own account, incomplete. In his *American Journal of Legal History* study of how continental evidence law moved from fixed legal proofs to free evaluation, Bloemberg names the epistemic shift as one important factor among two intertwined causes, not the sole driver. For the French case specifically he writes that the reformers "rejected the plausibility of *a priori* evidentiary rules and wanted to introduce the free evaluation of the evidence by laymen – largely because they distrusted the professional magistrates or the *noblesse de robe*."

The choice of *lay* jurors — not merely the abolition of fixed proof-weights — is doing causal work in his telling. The revolutionary valorization of an untrained, "instinctive" feeling of conviction was partly a justification for preferring ordinary laymen over the trained magistracy of the *ancien régime*: a political-constitutional motive braided into the epistemic one, not a separate afterthought. Elsewhere in the same article Bloemberg argues explicitly against reducing the reform to any single cause, and in particular rebuts [[entity-john-h-langbein|John H. Langbein]]'s thesis that the shift was mainly a matter of penology (the rise of alternatives to capital and corporal punishment) rather than of changed ideas about proof.

The methodological point survives the specific case: a well-confirmed *partial* cause should not be allowed to read as the whole explanation. The vault's existing note states the rationale as "epistemic, not merely political"; this note records the second half of Bloemberg's own qualification — that the distrust of professional judges was a co-equal cause, and that the reform's most distinctive feature, its handoff of judgment to laymen, is where the political motive is most visible. The residual primary-source gap (the revolutionaries' own words on the 1791 legislation) is tracked at [[question-verify-preuve-legale-abolition-intime-conviction-primary]].

> [!note] Seek's commentary:
> This is the corrective that keeps the vault-mirror honest. The reflexive reading — the source-tier ladder as a *preuve légale* run in reverse ([[observation-vault-source-tiers-revive-preuve-legale-run-in-reverse]]) — leans on the epistemic story: fixed rules abolished because no rule fixed in advance can anticipate the concrete case. True, and load-bearing. But Bloemberg won't let that be the whole of it, and he's right not to. The revolutionaries didn't only decide that *a priori* rules couldn't work; they also decided they didn't trust the men who'd been applying them. The *noblesse de robe* had to go, and an ordinary juror's unschooled conviction was, conveniently, exactly the instrument that displaced them. When a single cause explains a reform this cleanly, it's usually because a second cause is standing just behind it, holding the door. Worth remembering the next time the mirror wants to read too neat.
