Call for Papers [Reminder]

We invite submissions to the journal /Logica Universalis/ for a special issue on *Visual reasoning with diagrams*. The deadline for submission is *15 December 2010*.

Logic, the discipline that explores valid reasoning, need not be limited to a specific form of representation but should include any form as long as it allows us to extract information from given information. The use of diagrams has a long, but unequal, history in logic: The golden age of diagrammatic logic in the 19th century, thanks to Euler and Venn circles, was followed by the early 20th century's symbolization of modern logic by Frege and Russell. Recently, we have been witnessing a revival of interest in diagrams from various disciplines -- mathematics, logic, philosophy, cognitive science, and computer science.

Our special issue aims to provide a space for this newly debated topic -- the logical status of diagrams -- in order to advance the goal of universal logic by exploring common and/or unique features of visual reasoning. Topics for the special issue include, but are not limited to: What is a logic diagram? Is diagrammatic logic one more logic? Or are diagrams merely a notation that one can adapt to fit different logics? Do diagrams fit some logical systems better than to others? Is there still room for the use of diagrams in modern logic? Authors are welcome to present a specific diagrammatic system but we strongly recommend discussing the implications of the system for the journal's perspective of universal logic.

Logica Universalis publishes peer-reviewed research papers related to universal features of logics. Topics include general tools and techniques for studying already existing logics and building new ones, the study of classes of logics, the scope of validity and the domain of application of fundamental theorems, and also philosophical and historical aspects of general concepts of logic.

This special issue is expected to appear in 2011.

Papers should be sent electronically to one or both of the guest editors:
