This Handbook surveys the state of the art on ground as well as its connections and applications to other topics. The central issues of ground are discussed in 37 chapters, all written exclusively for this volume by a wide range of leading experts. "Grounding is one of the central topics in contemporary metaphysics. This collection represents the cutting edge of work in this fast-developing area, and is a must have both for veterans of debates about grounding and philosophers wanting to explore how thinking about grounding interacts with their favourite philosophical problems." --Daniel Nolan, University of Notre Dame
