Doing Metaphysics in Non-Classical Logic – Workshop

February 22, 2018

DOING METAPHYSICS IN NON-CLASSICAL LOGIC

Lisbon 22–23 February 2018

Organiser: Elia Zardini

TOPIC

Metaphysics offers its own conundrums, where a set of prima facie plausible principles apparently governing certain metaphysical notions (existence, change, composition etc.) can apparently be shown to be jointly untenable. Traditional approaches to such problems have typically focussed on rejecting one or the other of the metaphysical principles involved. However, at least in some cases, the reasoning supposed to show the untenability of the relevant metaphysical principles is nothing less than sustained, distinctively classical reasoning, similar to that at work in well-known paradoxes such as e.g. the Liar paradox or the Sorites paradox. While philosophers of logic have long been exploring the prospects of solving the latter paradoxes by revising classical logic, metaphysicians have only recently started to investigate non-classical approaches to puzzles in their area. The workshop aims at fostering this incipient kind of approach in metaphysics and at advancing our understanding of the role played by logic in the structure of certain metaphysical problems.
