MELOGNO, Pablo. Principios de justificación en la racionalidad informal de Hilary Putnam. Tópicos [online]. 2012, n.24, pp.00-00. ISSN 1666-485X.

In Reason, Truth and History, Hilary Putnam characterized informal rationality as an alternative that allows to overcome limitations evidenced by the formalist conceptions of rationality. Initially, the paper reviews the characterization provided by Putnam and establishes that, while Putnam denies any universal principle of rationality, he accepts relative, general and vague principles, that remain subject to needs of cognitive interrelationship with the environment. Secondly, we show that principles make exceptions and defend the possibility of reviewing principles whose denial is currently not conceivable. Finally, we state that both expressing and maintaining beliefs of controversy are historical elements that should be contemplated by an informal conception of rationality.
