Medieval interfaith disputations almost always ended in the adversary’s conversion.

Evidence

The only other example I know of a disputation that does not end in the conversion of the adversary is Abelard, Dialogus philosophi cum Iudeo et Christiano; on this text, see Von Moos, “Les collations d’Abélard.” — John V. Tolan, Saracens, 1961

Categorization

• SEED: The near-universal ‘conversion ending’ of medieval disputations is itself a telling literary formula—an essay could examine what the obligatory conversion ending reveals about how these supposedly open dialogues actually functioned.
• XREF: Connects to Llull’s own Libre del gentil, where the Gentile likewise ends on the verge of conversion—the author notes this as the striking exception.
