Many of the strands of what humans know about their own pleasure are pulled together in this chapter. The authors describe the psychological research on the experience and meta-awareness of pleasure. They show how many of our most pleasurable experiences occur with little meta-awareness of the fact that we are experiencing pleasure and how conscious attention to pleasure can distort or even destroy the underlying hedonic process.
