This book investigates the fundamental philosophical paradox of how an entity can undergo change while maintaining its identity as the same subject. Edo Pivcević, a scholar of continental philosophy, draws upon historical and analytical frameworks to argue that the intelligibility of change is inextricably linked to the nature of the self. By challenging naturalistic scientific explanations that fail to account for the persistence of identity through transformation, the author constructs a metaphysical argument for the necessity of the self in any coherent theory of change.

Scholars and students of metaphysics frequently cite this work for its rigorous approach to the classic problem of identity. Readers often note the density of the prose, which requires a strong background in philosophical terminology to fully grasp the author's arguments.
