Being Without Foundations: Events

Varieties of Non-Wellfoundedness Workshop

Friday 16th - Sunday 18th December, 2022

Ligerz, Switzerland

On the standard view, reality is well-founded, roughly in the sense that everything is finitely many steps of immediate grounding away from the fundamental. Various authors have distinguished and taxonomised ways in which the standard view might fail. Still, much of the territory is unexplored. In this workshop, which forms part of the project “Being without Foundations” (funded by the Swiss National Science Foundation), we aim to bring together researchers working on phenomena of non-wellfoundedness in metaphysics (involving relations such as grounding, explanation, causation, constitution, relative fundamentality, and parthood). We are interested both in new arguments for or against the well-foundedness of a certain relation, and in new distinctions among non-wellfounded structures.

Philosophical Applications of Modal Logic Workshop

Thursday 14th May, 2020

University of Glasgow (via Zoom)

The formalism of modal logic has established itself as an enormously fruitful extension of standard propositional logic. The operators it introduces, originally interpreted to stand for necessity and possibility, can be given a range of different interpretations. Today, a great deal of specialised work is being done in modal logic, and the formalism is widely used in a number of fields, notably linguistics, computer science, and game theory. The aim of this workshop is to develop and discuss distinctly philosophical application of modal logic. The speakers are invited to report on new technical work in their talks, but place the emphasis on its motivation and application to philosophical applications rather than its mathematical interest. The workshop will of interest to  formally-minded philosophers, giving them the chance to learn about the state of the art in the use of a key device in their theoretical tool-kit.
