Modern logic is undergoing a cognitive turn, side-stepping Frege’s ‘antipsychologism’. Collaborations between logicians and colleagues in more empirical fields are growing, especially in research on reasoning and information update by intelligent agents. We place this border-crossing research in the context of long-standing contacts between logic and empirical facts, since pure normativity has never been a plausible stance. We also discuss what the fall of Frege’s Wall means for a new agenda of logic as a theory of rational agency, and what (...) might then be a viable understanding of ‘psychologism’ as a friend rather than an enemy of logical theory.

A central and influential idea among researchers of language is that the sentence, by virtue of its direct relationship with syntactic parsing, represents the heart of language itself. Even in the field of pragmatics, models rooted in classical theories tend to put sentence prominence forward again. Here, we present results from recordings of event-related brain potentials that brings into question even the distinction between sentence and discourse. During natural communicative exchanges, the human brain continuously and immediately relates incoming words to (...) the previous discourse, whether it is constituted of a word, a sentence or complex speech. Moreover, focusing on discourse instead of sentence represents a viable strategy to better understand the relationship between language and other cognitive systems. (shrink)
