Talking politics: Perils and promise

In its recent 'deliberative' turn, democratic theory has forgotten a conventional wisdom, once widely appreciated, that there is much in politics that is better not discussed. In this article, the author catalogues what topics might be deemed 'politically undiscussable', and why, as a first step toward showing how and to what extent talking about such matters might help or hinder their resolution. One important way discussion helps is by information-pooling to establish the truth of the matter. Even where that is not a viable aspiration, discussion might nonetheless serve a 'premise-revealing' function, showing one another that we are reasonable agents and thus helping to desensitize contentious issues.
