This volume investigates the central metaphysical question of whether all truths require a truthmaker, an entity in virtue of which they are true. The authors, Julian Dodd and Helen Beebee, provide a rigorous examination of the truthmaker principle, tracing its development within contemporary analytic philosophy. They evaluate the logical implications of various truthmaker theories and assess the ontological commitments required to sustain them.

This text is widely regarded as a foundational resource for students and researchers navigating the complexities of truthmaker theory. Experts frequently highlight the clarity of the authors' prose and their ability to distill dense logical arguments into a coherent framework for further study.
