  He repeated the denial of innate ideas in the Corollaries of 1647: “The mind does not need innate ideas, or notions, or axioms; its faculty of thinking alone is enough for it to perform its own actions” (Regius 1647b, Corollary 12). Descartes’ reply, in the Notae (Descartes 1648), conceded the validity of Regius’ claim by accepting that their disagreement was merely verbal: “I never wrote or claimed that the mind needs innate ideas which are anything other than its faculty of thinking” (AT VIII-2, 357). Regius subsequently generalized his claim, in Philosophia naturalis (1654: 335); apart from what is revealed in Scripture, he argued, all thoughts originate in sensory experience.
