Studia Logica is extending its scope. In future the journal will not only cover pure logic but also applications of formal-logical methods in philosophy and cognitive science. To mark this change, the journal is planning to do several special issues. One of these will be on:

Psychologism in Logic?

Call for Papers

After the classic psychologism debate in the late 19th century, Frege and Husserl seemed to have extinguished all psychological traits from formal logic. However, in the last few decades a new picture of logic has emerged according to which logical laws are sometimes regarded as high-level descriptions of ideal cognitive agents: Systems of belief revision and update are justified by semantic evaluations of formulas in terms of epistemic entrenchment or ranks of subjective plausibility; nonmonotonic logic takes the rationality of commonsense reasoning seriously in order to enable artificial agents to draw reliable inferences in the face of incomplete and uncertain information; dynamic epistemic logic studies the logical properties of epistemic and social actions, whether in communication, games, or judgment aggregation; state transitions in artificial neural networks have been described by means of consequence relations which are closed under logical rules. Is this the return of a new and "enlightened" version of psychologism in logic? Is there a genuine notion of a logical agent? Are there agent-relative concepts of correctness or validity that have an interesting logical structure? Are problems in cognitive science taking over the role that questions in the foundations of mathematics have played traditionally in the development of logic?

This special issue of Studia Logica will be devoted to whether there is a new psychologism in logic and if so what it looks like. The papers should investigate this topic by studying formal systems by formal tools from logic broadly understood. Additionally, empirical and philosophical considerations can be directed towards the formal properties of these systems, but only on the basis of axiomatic or semantic treatments and established theorems. Four papers of the issue will be invited ones while the rest will be selected based on peer reviewing.
