We live in a world where everything appears to be explained by neuroscience, evolutionary psychology and biology. And yet, and yet:
Allow children to interact with real people, therefore, and the grammar of first-person accountability will emerge of its own accord. Undeniably, once it is there, the I-to-you relation adds a reproductive advantage, just as do mathematical competence, scientific knowledge and (perhaps) musical talent. But the theory of adaptation tells us as little about the meaning of “I” as it tells us about the validity of mathematics, the nature of scientific method or the value of music.
To describe human traits as adaptations is not to say how we understand them. Even if we accept the claims of evolutionary psychology, therefore, the mystery of the human condition remains. This mystery is captured in a single question: how can one and the same thing be explained as an animal, and understood as a person?
