This book investigates whether the attributes of God can be derived from the principle that God is the greatest possible being. Jeff Speaks, a professional philosopher, evaluates the historical and contemporary tradition of philosophical theology. He presents a critical argument that the project of defining God through this specific principle is fundamentally flawed and proposes an alternative framework for future theological inquiry.

Experts in the field of philosophy of religion identify this work as a rigorous challenge to established metaphysical assumptions regarding the divine. Readers frequently note the technical density of the prose, which is intended for an audience familiar with analytic philosophy and formal theological discourse.
