“This is How Things Are”

Proponho uma interpretação das observações de Wittgenstein nas Investigações Filosóficas (§§ 134-6) sobre a doutrina da ‘forma proposicional geral’ exposta no Tractatus. Contra a leitura predominante, sustento que essas passagens contêm uma defesa, ao invés de uma rejeição sumária, do que eu alego ser o núcleo daquela doutrina. Recorro ao comentário de A. N. Prior ao § 134 das Investigações para salientar a estrutura anafórica do exemplo que dá Wittgenstein do uso, na linguagem ordinária, de uma variável proposicional. Encerro a discussão com um breve aceno à vulnerabilidade da fundação (grounding) de cadeias anafóricas.

I offer an interpretation of Wittgenstein’s remarks in Philosophical Investigations (§§ 134-6) about the doctrine of a ‘general propositional form’ as it was presented in the Tractatus. Against the prevailing reading, I argue that these sections contain a vindication, rather than an out and out rejection, of what I claim to be the kernel of that doctrine. I make use of A. N. Prior’s gloss on § 134 of the Investigations to underscore the anaphoric structure of Wittgenstein’s example of the use, in ordinary language, of a propositional variable. I round up the discussion with a brief glance at the vulnerability of grounding of anaphoric chains.
