Does the existence of indeterminacy in the physical world provide a sufficient foundation for human free will? Robert J. Kane, a prominent philosopher of mind and action, examines the compatibility of libertarian free will with a scientific understanding of the universe. He constructs a framework that argues for the necessity of self-forming actions as the mechanism through which individuals exert agency in an otherwise causal world.

Scholars frequently identify this work as a foundational text for understanding contemporary libertarian arguments in the free will debate. Experts note the high level of technical rigor in the prose, making it a standard reference for advanced students of metaphysics and ethics.
