Moral politics: how liberals and conservatives think

"In this classic text, the first full-scale application of cognitive science to politics, George Lakoff analyzes the unconscious and rhetorical worldviews of liberals and conservatives, discovering radically different but remarkably consistent conceptions of morality on both the left and right. For this new edition, Lakoff adds a preface and an afterword extending his observations to major ideological conflicts since the book's original publication, from the impeachment of Bill Clinton to the 2000 presidential election and its aftermath." http://catdir.loc.gov/catdir/description/uchi051/2001051052.html
