Cartesian Epistemology: Is the theory of the self-transparent mind innate?

This paper argues that a Cartesian belief in the self-transparency of minds might actually be an innate aspect of our mind-reading faculty. But it acknowledges that some crucial evidence needed to establish this claim hasn't been looked for or collected. What we require is evidence that a belief in the self-transparency of mind is universal to the human species. The paper closes with a call to anthropologists (and perhaps also developmental psychologists), who are in a position to collect such evidence, encouraging them to do so.
