This volume investigates the fundamental question of what constitutes an individual and how such entities can be identified across disparate scientific and metaphysical frameworks. Editors Alexandre Guay and Thomas Pradeu assemble a collection of interdisciplinary essays that bridge the gap between metaphysical theory and empirical practice in physics and biology. The work argues that current criteria for individuality are fragmented, necessitating a unified conceptual approach to reconcile these fields.

Experts recognize this volume as a significant attempt to synthesize cross-disciplinary definitions of individuality that are often siloed within specific departments. Scholars frequently note that the text provides a necessary foundation for future research into the intersection of metaphysics and the empirical sciences.
