Ricoldo’s rationalist arguments against Islam were later turned against Christianity itself

Evidence

There was a deeper weakness in Ricoldo’s approach. He was lucky not to have to refute the very arguments that he used against Islam, but brought against Christian doctrine, as many of his very rationalist arguments would in fact be brought in later ages. — Norman Daniel, Islam and the West, 374

Categorization

  • DEEPTHINKING: The insight that a polemicist’s own weapons become usable against him — and that Ricoldo was merely lucky not to face them — is a genuinely paradigm-shifting observation about religious dispute.
  • corroborated: 2 independent passages support this claim — Norman Daniel, Islam and the West, 374
  • XREF: connects to: Voltaire attacked Muhammad as a mask for criticizing Christianity itself; Pope Benedict’s attack on Islamic irrationality ignored Christianity’s own persecution of reason — Deepa Kumar, Islamophobia and the Politics of…, 342
