The Destruction of Reason,The Desires of Conservatism.
Conservatism has opposed rational thought for thousands of years. What most people know nowadays as conservatism is basically a public relations campaign aimed at persuading them to lay down their capacity for rational thought.
Conservatism frequently attempts to destroy rational thought, for example, by using language in ways that stand just out of reach of rational debate or rebuttal.
Conservatism has used a wide variety of methods to destroy reason throughout history. Fortunately, many of these methods, such as the suppression of popular literacy, are incompatible with a modern economy. Once the common people started becoming educated, more sophisticated methods of domination were required. Thus the invention of public relations, which is a kind of rationalized irrationality. The great innovation of conservatism in recent decades has been the systematic reinvention of politics using the technology of public relations.
The main idea of public relations is the distinction between "messages" and "facts". Messages are the things you want people to believe. A message should be vague enough that it is difficult to refute by rational means. (People in politics refer to messages as "strategies" and people who devise strategies as "strategists". The Democrats have strategists too, and it is not at all clear that they should, but they scarcely compare with the vast public relations machinery of the right.) It is useful to think of each message as a kind of pipeline: a steady stream of facts is selected (or twisted, or fabricated) to fit the message. Contrary facts are of course ignored. The goal is what the professionals call "message repetition". This provides activists with something to do: come up with new facts to fit the conservative authorities' chosen messages. Having become established in this way, messages must also be continually intertwined with one another. This is one job of pundits.
To the public relations mind, the public sphere is a game in which the opposition tries to knock you off your message. Take the example of one successful message, "Gore's lies". The purpose of the game was to return any interaction to the message, namely that Gore lies. So if it is noted that the supposed examples of Gore lying (e.g., his perfectly true claim to have done onerous farm chores) were themselves untrue, common responses would include, "that doesn't matter, what matters is Gore's lies", or "the reasons people believe them is because of Gore's lies", or "yes perhaps, but there are so many other examples of Gore's lies", or "you're just trying to change the subject away from Gore's lies", and so on.
Many of these messages have become institutions. Whole organizations exist to provide a pipeline of "facts" that underwrite the message of "liberal media bias". These "facts" fall into numerous categories and exemplify a wide range of fallacies. Some are just factually untrue, e.g., claims that the New York Times has failed to cover an event that it actually covered in detail. Other claimed examples of bias are non sequiturs, e.g., quotations from liberal columns that appear on the opinion pages, or quotations from liberals in news articles that also provided balancing quotes from conservatives. Others are illogical, e.g., media that report news events that represent bad news for the president. The methods of identifying "bias" are thus highly elastic. In practice, everything in the media on political topics that diverges from conservative public relations messages is contended to be an example of "liberal bias". The goal, clearly, is to purge the media of everything except conservatism.
