For me, one of the most poignant effects of the ignorance of metaphorical thought is the mystification of liberals concerning the recent electoral successes of conservatives. Conservatives regularly chide liberals for not understanding them, and they are right. Liberals don't understand how anti-abortion "right-to-life" activists can favor the death penalty and oppose reducing infant morality through prenatal care programs. They don't understand why budget-cutting conservatives should spare no public expense to build prison after prison to house even non-violent offenders, or why they are willing to spend extra money to take children away from their mothers and put them in orphanages --- in the name of family values. They don't understand why conservatives attack violence in the media while promoting the right to own machine guns. Liberals tend not to understand the logic of conservatism; they don't understand what form of morality makes conservative positions moral or what conservative family values have to do with the rest of conservative politics. The reason at bottom is that liberals do not understand the form of metaphorical thought that unifies and makes sense of the full range of conservative values.

If this analysis is right, or even close to right, then a great deal follows. Liberals do not understand what unifies their own worldview and so are helpless to deal effectively with conservatism. Not only is there no unified liberal political structure, but there is no overall effective liberal rhetoric to counter the carefully constructed conservative rhetoric. Where conservatives have carefully coined terms and images and repeated them until they have entered the popular lexicon, liberals have not done the same. Liberals need to go beyond coalitions of interest groups to consciously construct a unified language and imagery to convey their worldview. This will not be easy, and they are 30 years behind.
