Parts of Philosophy in the Flesh retrace the ground covered in the authors' earlier Metaphors We Live By, which revealed how we deal with abstract concepts through metaphor. (The previous sentence, for example, relies on the metaphors "Knowledge is a place" and "Knowing is seeing" to make its point.) Here they reveal the metaphorical underpinnings of basic philosophical concepts like time, causality--even morality--demonstrating how these metaphors are rooted in our embodied experiences. They repropose philosophy as an attempt to perfect such conceptual metaphors so that we can understand how our thought processes shape our experience; they even make a tentative effort toward rescuing spirituality from the heavy blows dealt by the disproving of the disembodied mind or "soul" by reimagining "transcendence" as "imaginative empathetic projection." Their source list is helpfully arranged by subject matter, making it easier to follow up on their citations. If you enjoyed the mental workout from Steven Pinker's How the Mind Works, Lakoff and Johnson will, to pursue the "Learning is exercise" metaphor, take you to the next level of training. --Ron Hogan
