De la racionalidad a la razonabilidad: ¿es posible una fundamentación epistemológica de una moral “política”?

The main argument of this paper tries to justify some duties of respect and tolerance common in liberal societies. The argument proceeds in four steps. First, it shows that a rational person (in a broad sense) will take seriously into account the Rawlsian "burdens of judgment”. The second step tries to prove that taking the burdens of judgment seriously leads a rational person to a fallibilist position regarding moral doctrines (in the sense of assuming that the own comprehensive moral view can be wrong). The third (and crucial) step of the argument aims to derive a tolerant attitude toward other (incompatible) conceptions of the good from the fallibilist position. And, finally, some limits of this attitude based on the same fallibilist position are considered and discussed.
