A vagueza é comumente representada pela adoção de significados imprecisos na linguagem natural. Ela é analisada como um caso limítrofe e formalizada de diversas maneiras pelas suas teorias “clássicas”. Este trabalho propõe uma abordagem diferente do tema através da adoção do conceito de Racionalidade Soft ( Soft Rationality ), elaborado por Marcelo Dascal, e da sua interpretação como o uso da “semelhança” ao invés da “análise” para a compreensão dos termos da linguagem natural. Aqui será feita a sugestão de que (...) a Racionalidade Soft (branda), enquanto teoria sobre a vagueza, permanece no domínio da ‘intensionalidade’ ao invés de buscar uma explicação formalizada e ‘extensional’ para o tema.

According to an “orthodox” reading proposed by Dummett and more recently endorsed by Lugg and Price, the later Wittgenstein rejects the idea of grouping together certain utterances as a single class of assertions. We offer an alternative commentary on the Philosophical Investigations §§21–24, developing what we call a Wittgensteinian role‐based account of assertion. We then examine whether this role‐based account can solve the problem of on‐stage utterances. In the course of this, the merits of the account are shown and compared (...) to an alternative proposal offered by Searle. (shrink)

In trying to make clear whether understanding is a mental state Wittgenstein asks a series of questions about the timing and duration of understanding. These questions are awkward, and they have posed a great challenge for commentators. In this paper I review the interpretations by Mole and by Baker and Hacker, and point out their problems. I then offer a new interpretation which shows (1) that a “mental state” in this context means a state of consciousness, (2) that Wittgenstein's questions (...) are intended to elicit the grammars of the words “understand” and a “state of consciousness”, (3) that, in this way, he clearly shows that understanding is not a state of consciousness and (4) that he also provides a therapy to dissolve the problem.

In this paper, I examine the grammatical nature of Wittgenstein's private language argument (PLA). On my interpretation, the definition of private language implies that the private speaker has no natural expressions for his sensations. This in turn implies that he has no criterion of correctness for using his sensation‐words. This then implies, together with the grammatical rule that a word is senseless without a criterion of correctness for its use, that private sensation‐words are senseless, and hence also that private language (...) is senseless. So in my analysis, Wittgenstein succeeds in dissolving the problem of private language through a grammatical investigation, and therefore, his treatment of private language is consistent with his metaphilosophy. I further explain that Wittgenstein provides a diagnosis of the error of the philosopher who thinks that private language is possible and that he also offers a therapy consisting of analogies or objects of comparison. I also make a comparison with previous studies on the PLA and discuss a number of novelties in my interpretation. (shrink)
