Brown (2022) has recently argued that metaethical expressivists should adopt an interpretationist account of propositional attitudes. Expressivism has traditionally been the view that moral judgments are best understood as desire-like states with a primarily practical function of guiding and producing actions. Most problems for expressivists, however, come from the fact that moral judgments have many belief-like properties: being truth evaluable, epistemically evaluable, embeddable in complex truth-functional constructions, etc. By adopting Brown’s proposal, expressivists would avoid several of these problems since they could claim that moral judgments are just beliefs but of a non-representational variety. In this article, I argue that, while promising, this view has a substantial problem. A crucial element of the rationalising interpretation is that beliefs are governed by a norm of aiming at truth. But contrary to what Brown suggests, deflationist accounts of truth cannot help expressivists explain why moral judgments are also subject to this norm. Brown (2022) ha argumentado recientemente que los expresivistas metaéticos deberían adoptar una concepción interpretacionista de las actitudes proposicionales. Tradicionalmente, el expresivismo ha sostenido que los juicios morales se entienden mejor como estados similares al deseo, con una función principalmente práctica de guiar y producir acciones. Sin embargo, la mayoría de los problemas para los expresivistas provienen de que los juicios morales tienen muchas propiedades similares a las creencias: son evaluables en cuanto a la verdad y epistémicamente, integrables a construcciones complejas veritativo-funcionales, etc. Si adoptasen la propuesta de Brown, los expresivistas evitarían varios de estos problemas, ya que podrían afirmar que los juicios morales son creencias, solo de un tipo no representacional. En este artículo sostengo que, aunque prometedora, esta postura tiene un problema sustancial. Un elemento crucial de la interpretación racionalizadora es que las creencias se rigen por la norma de apuntar a la verdad; sin embargo, contrario a lo que sugiere Brown, las explicaciones deflacionistas de la verdad no pueden ayudar a los expresivistas a dar cuenta de por qué los juicios morales también están sujetos a esta norma.Brown (2022) has recently argued that metaethical expressivists should adopt an interpretationist account of propositional attitudes.
