Workshop: Abduction and Modelling in Metaphysics

Description: Methodological questions have been in the focus of many recent philosophical debates. The role of thought experiments, the method of cases, intuitions, etc. has been studied intensively within metaphilosophy. This reflective attitude is often considered to be a characteristic feature of philosophical investigation and, hence, it is no surprise that occasionally it results in some kind of self-application. In metaphysics, recent severe criticism of traditional investigations led to quite versatile metametaphysical stances: There is the radical sceptical approach according to which metaphysical studies better dissolve in the corresponding branches of science rather than being performed in an encapsulated way; and there is the other end of the spectrum according to which metaphysics is a self-standing endeavour to be conducted in an a priori fashion. In between are more moderate stances proposing that metaphysical investigation ought to employ both, scientific findings and methods on the one hand, and conceptual analysis and methods of traditional metaphysics on the other. Inductive metaphysics, for example, aims at applying the abductive and modelling methodology of science within metaphysical investigation. Such an approach, however, raises several questions: What does the abductive methodology exactly consist in and what is its epistemic rationale? How are metaphysical models to be characterised and evaluated and what constitutes metaphysical data and evidence? What distinguishes such an inductive metaphysical approach from naturalising metaphysics? This workshop aimed at exploring some of these and related questions regarding the theoretical presuppositions of metaphysical methodology.

Date: December 6 to 7, 2018

Place: Haus der Universitaet (Schadowplatz 14, 40212 Duesseldorf) of the University of Duesseldorf
