Dear friends here is "the turnip", two men are complete opposites into a secret correspondence is Bhl and Houellebecq, the result: MINABLE !!! To those who truly want a dialogue between two philosophers are total opposites, there Gaston Bachelard and Louis Althusser. Two true philosophers. The result is a match, or both exchanges splendidly but above show both their admiration for their ideas. But above all the fact that they recognize themselves in the opposite of what they are. In this case we can speak of Philosophy.
