Robert B. Talisse in This Side of the Pond (The Blog of Cambridge University Press):
Political commentary proceeds by means of debate rather than report today.
This is an understandable consequence of the new technology, which makes engagement easy. The heightened exposure to debate is a good thing, too. Open debate is democracy’s lifeblood. Yet popular political disagreement has taken on an odd hue. Rather than presenting facts and professing a view, commentators present views concerning the views of their opponents. Despite heated disagreements over Big Questions like healthcare, stem-cells, abortion, same-sex marriage, and global warming, we find a surprising consensus about the nature of political disagreement itself: All agree that, with respect to any Big Question, there is but one intelligent position, and all other positions are not merely wrong, but ignorant, stupid, naïve. A minute in the Public Affairs section of a bookstore confirms this: Conservatives should talk to liberals “only if they must” because liberalism is a “mental disorder.” Liberals dismiss their Conservative opponents, since they are “lying liars” who use their “noise machine” to promote irrationality.
Both views betray a commitment to the Simple Truth Thesis, the claim that Big Questions always admit of a simple, obvious, and easily-stated solution. The Simple Truth Thesis encourages us to hold that a given truth is so simple and so obvious that only the ignorant, wicked, or benighted could possibly deny it.
