Brentano and Mauthner on grammatical illusions

This paper aims to suggest that Brentano’s theory of intentionality, at least in its later formulation, is not only about mind and also belongs to a tradition of deconstructing language that includes prominent figures of Austrian and German philosophy such as Mach, Vaihinger, and Wittgenstein. In order to establish this, the author explores some differences and similarities between this theory and Fritz Mauthner’s critique of language. He argues that the very starting point of both is one and the same fact: the failure of existential generalization.
