William Ockham

This comprehensive study of William Ockham examines the fourteenth-century Franciscan philosopher's distinctive theological contributions, particularly his innovative approach to understanding divine nature and human knowledge of God. Adams presents Ockham as a pivotal figure who challenged prevailing scholastic assumptions about natural theology while maintaining a fundamentally theistic framework grounded in divine omnipotence and radical contingency.

The work analyzes Ockham's rejection of universal essences and his nominalist metaphysics, demonstrating how these positions reshape traditional arguments for God's existence. Adams shows that Ockham undermines the metaphysical realism underlying Aquinas's Five Ways, arguing that abstract concepts have no extramental reality. This nominalism does not lead Ockham to atheism but rather to a different understanding of how humans can know God. The monograph carefully traces Ockham's argument that while natural reason can establish God's existence as an efficient cause, it cannot demonstrate divine attributes like unity, infinity, or perfection through philosophical argumentation alone.

Adams explores Ockham's emphasis on divine freedom and absolute power, showing how this voluntarism creates tension with natural theology's claims to necessary truths about God. The work examines Ockham's distinction between God's absolute power (potentia absoluta) and ordained power (potentia ordinata), revealing how this framework preserves both divine sovereignty and the reliability of creation's order. This analysis illuminates Ockham's contribution to later debates about the relationship between reason and revelation.

The monograph situates Ockham within medieval theological controversies, particularly disputes with Duns Scotus over divine simplicity and with Thomas Aquinas over the demonstrability of theological truths. Adams argues that Ockham's critique of metaphysical necessity in theology anticipates modern skepticism about natural theology while remaining firmly committed to Christian theism through faith. The work demonstrates how Ockham's fideism differs from later Protestant approaches by maintaining that reason, though limited, plays a legitimate role in theological reflection.

Adams's study reveals Ockham as a sophisticated theological thinker who restricts philosophy's scope regarding God not to diminish divine reality but to preserve divine transcendence. This interpretation challenges readings of Ockham as merely destructive, showing instead how his nominalism and voluntarism constitute a coherent theological vision that influenced subsequent debates about religious epistemology and the limits of human reason in approaching the divine.
