Thinking of Necessity

Jessica Leech sets out a Kant-inspired theory of modality, i.e. possibility and necessity. She argues that we need logical modal concepts as a condition on our ability to think, and metaphysical modal concepts as a condition on our ability to think about the world. Necessity has its source in the laws of thought and the conditions of thought.

Jessica Leech joined the King's College London Philosophy department in September 2016. She was previously a lecturer at the University of Sheffield, and a Junior Research Fellow at King's College, Cambridge. She did her doctorate jointly at the University of Sheffield and the University of Geneva (as part of the "Theory of Essence" research project based at the Eidos Centre for Metaphysics at the University of Geneva), supervised by Fabrice Correia and Bob Hale.
