Including in the same book philosophical essays and political essays may seem at first sight an extravagance or nonsense, if the first matter is understood as mere speculation without handle with reality and the second is clinging to the pure facts without possibility Some of the flight. However, the experience has a long and fruitful history, both in American pragmatism, from James and Dewey to Rorty and Quine, and in the German doctrine itself, with figures such as Adorno, Horkheimer and Habermas. Overflying each other, the extraordinary presence of the British Russell. And it is that between philosophical reflection and political analysis there is no insuperable incompatibility, but rather dialectical closeness, insofar as one and the other move within the realm of logical parameters and have to resort to mental operations of very similar, if not Equal, rational texture. Thus, when it is affirmed that rational argument and dialogue are fundamental for the proper functioning of a political system, the same can be said for the correct operation of a philosophical system, both linked to the best presence and performance of the human mind. To intercalary in the same work the political analysis and the philosophical reflection can produce the salutary dual effect of which it helps the reader to raise the mental tone to read a political work after having read another philosophical one, and of that it contributes to lowering the delusions inflexions in the face To a philosophical chapter after having crossed the pragmatic and realistic terrain of another political chapter. It is possible the interaction between one and another matter, which does not have to be harmful, extravagant or reckless.
