The different sciences furnish us with a wide variety of explanations: some work at macroscopic scales, some work at microscopic scales, and some operate across different levels. How do these different explanatory levels relate to one another, and what is an explanatory level in the first place? Over the last 50 years, more and more philosophers--both reductionists and anti-reductionists--no longer subscribe to the idea that the best explanation resides at the fundamental physical level. New challenges arise from the success of scientific explanations employing multi-level models which mix levels of explanation, from distinctive differences between levels structures in biology, cognitive science, and social science, from the apparently radical reimagining of the explanatory role of spacetime in our current best theories of fundamental physics, and from the enduring mystery of how higher-level explanations are possible in the first place. These questions naturally connect to classic philosophical ways of thinking about the relationships between levels: reduction, emergence, and fundamentality. This volume presents a snapshot of cutting-edge research on explanatory levels, from their conceptual foundations to the details of how they are used in scientific practice.

Katie Robertson is Lecturer in Philosophy at the University of Stirling. After completing the BPhil in Philosophy in Oxford, she did her PhD in Cambridge on the philosophy of thermal physics. She was then a postdoc with the FraMEPhys project at the University of Birmingham, before being awarded a Leverhulme Early Career Fellowship exploring the relationship between thermodynamics and black holes. Her research has focused on questions about how different sciences, or levels, fit together. She has also worked on how non-fundamental theories such as thermodynamics and their quantities like entropy are related to more fundamental quantities in quantum mechanics.
Alastair Wilson is Professor of Philosophy at the University of Leeds, specializing in metaphysics, philosophy of science (especially physics), and epistemology. Before joining Leeds, he spent 11 years at the University of Birmingham and 18 months as a postdoc at Monash University. His doctoral thesis was on the metaphysics of Everettian (many-worlds) quantum mechanics; this line of thought culminated in his book
The Nature of Contingency: Quantum Physics as Modal Realism (OUP, 2020). More recently he has focused on explanation and dependence in physics; he has also worked on grounding, laws of nature, chance, and the epistemology of self-locating belief.
