Abstract

Descartes is often accused of lacking a coherent conception of innate ideas. I argue that Descartes' remarks on innate ideas actually form a unified account. "Innate idea" is triply ambiguous, but its three meanings are interdependent. "Innate idea" can mean an act of perceiving; that which is perceived; or a faculty, capacity, or disposition to have certain ideas. An innate idea qua object of thought is some thing existing objectively , which we have a capacity to perceive, but which we can only actually perceive through meditation. ;Descartes thinks that some innate ideas, such as the idea of thought itself, are implicit in the very process of thinking. Because they are relied on in thinking itself, we have implicit awareness of them. We also have implicit knowledge of other ideas contained in them. The actual perception of these innate ideas is, for Descartes, a matter of making them explicit, turning the intellect away from sense-perceptions and towards pure thought. ;Some innate truths, Descartes says, are perceived by the "natural light." I argue that such truths are made explicit through attending to how the concepts which those truths are about have been relied on in the process of thinking. I discuss the relationship between the natural light and the will, arguing that other accounts of Descartes' "natural light" in the secondary literature are unsatisfactory. I also explore how Descartes' use of the metaphor of light might have been informed by his scientific views about light. ;The innate ideas of corporeal nature and mathematics are also made explicit through attention and reflection, according to Descartes. Though many commentators read Descartes as holding that the innate idea of extension can be known without any use of the senses, I argue that it is discovered through reflection on our sense-perceptions. Once this idea is explicit, Descartes thinks, we can use it to generate explicit awareness of further innate ideas, such as ideas of shapes. Reflection on those further innate ideas, in turn, makes explicit various innate truths about those shapes
