Special Issue of Studia Logica
on
"Psychologism in Logic?"

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.
