MIRANDA-ROJAS, Rafael. The hybridity of what is necessary a posteriori. discus.filos [online]. 2020, vol.21, n.36, pp.53-78.  Epub Dec 09, 2020. ISSN 0124-6127.  https://doi.org/10.17151/difil.2020.21.36.5.

This paper proposes that what is necessary a posteriori corresponds to a hybrid case of justification, without this leading to an extreme rationalist commitment. In the cases of necessary a posteriori statements, the logical principles that they instantiate are of a priori nature, and the information of statements such as "Water is H2O" or "Pain is the stimulation of the fiber - c" are knowable only a posteriori. In order to explain this hybridity, how the reductio strategy allows accepting a moderate rationalist approach will be discussed. Bootstrapping will be considered as a paradigmatic case of hybrid epistemic justification. The discussion regarding the a priori - a posteriori nexus tends to establish a hierarchy in which one of the epistemic accesses is privileged, which will be rejected.

Keywords : Necessity; a posteriori; a priori; conceivable; possible.
