Workshop at the 5th World Congress on Universal Logic: The Idea of Logic, Historical Perspectives

Workshop at the 5th World Congress on Universal Logic, 25-30 June 2015 - Istanbul, Turkey

Workshop organized by: Juliette Lemaire (CNRS, Centre Léon Robin, France) & Amirouche Moktefi (Tallinn University of Technology, Estonia)

Logic as a discipline is not characterized by a stable scope throughout its history. True enough, the historical influence of Aristotelian logic over the centuries is something of a common denominator in Western philosophy. But Aristotelian logic certainly was not alone (see stoic logic for instance), not to mention non-western logics. Even within the Aristotelian tradition there is significant variability. Furthermore, as is well known, in the 19th century logic as a discipline underwent a radical modification, with the development of mathematical logic. The current situation is of logic having strong connections with multiple disciplines - philosophy, mathematics, computer science, linguistics - which again illustrates its multifaceted nature. 

The changing scope of logic through its history also has important philosophical implications: is there such a thing as the essence of logic, permeating all these different developments? Or is the unity of logic as a discipline an illusion? What can the study of the changing scope of logic through its history tell us about the nature of logic as such? What do the different languages used for logical inquiry - regimented natural languages, diagrams, logical formalisms - mean for the practices and results obtained?

This workshop will focus on both the diversity and the unity of logic through time. Topics may include:
  • Historical analyses on what specific logicians or logic traditions considered to be the nature and scope of logic. 
  • Historical analyses illustrating differences in scope and techniques with respect to the current conception of logic, but also suggesting points of contact and commonalities between these past traditions and current developments 
  • Historical and philosophical discussions on the place of logic among the sciences and its applications/relations with other disciplines, now and then. 
  • Discussions of the logical monism vs. logical pluralism issue in view of the historical diversity/unity of logic over time 
  • General philosophical reflections on what (if anything) the diversity of scope and practice in the history of logic can tell us about the nature of logic and the role of universal logic as such.
