Where can I get me some epistemology like that?

Dualism–the theory that mind and body are two distinct entities which interact with each other–has poisoned human behavior over the last thousand years or so. From dualism, we get the notion that the pleasures of the mind are “noble” while the pleasures of the flesh are “sinful.” We see the separation between inhumane logic and passionate emotion, never imagining that they spring from the same source. It’s taken scientists and philosophers centuries to beat back this curtain of ignorance; progress has been slow.

And then Rick Springfield’s “Jessie’s Girl” comes along and undoes all the good work.
