Gottfried Wilhelm Leibniz

An OMAF Case Study (Revised)

Gottfried Wilhelm Leibniz at the blackboard in his study, writing equations and monad diagrams for his audience. With his right hand he presents a rational system of pre-established harmony; with his left hand, clutched behind his back, he conceals the Bible on which it truly rests—a visual metaphor for an ontology founded on faith, not reason.

1. Overview of the Ontology

Purpose & Scope:

Leibniz's monadology aims to explain reality through simple, immaterial substances called "monads" that form the ultimate building blocks of existence. This system reconciles metaphysical simplicity with the complexity of our experienced world, addressing everything from physical objects to consciousness within a single hierarchical framework. The scope is universal, claiming to account for all phenomena through the properties and relations of these fundamental units.^[1]

Core Claims:

• The ultimate constituents of reality are simple, immaterial substances called monads
• Monads are "windowless"—they have no causal interaction with one another
• Each monad mirrors the entire universe from its unique perspective
• A pre-established harmony coordinates all monadic states without interaction
• Our world is the "best of all possible worlds" chosen by God's perfect reason^[2]

Foundational Critique:

Leibniz's entire system rests on the doctrine of creatio ex nihilo — the claim that God creates monads from nothing. Leibniz himself admits that "reason cannot fully comprehend how God has produced being from nothing... these are matters of faith, not reason."^[3] The system is therefore not a rational ontology but a theological artifact founded on an assumption of faith — a foundation it attempts to hide beneath a rationalist facade.

4. Summary & Observations

Strengths (Revised):

Leibniz's system retains transformative potential and heuristic generativity. The cognitive shift from material to mental primacy remains philosophically interesting, even if its foundation is faith. The system's historical influence is undeniable and unaffected by the critique.

Weaknesses (Revised):

The ontology's grounding is fatally compromised. What appears as a rational foundation (creatio ex nihilo) is, by Leibniz's own admission, a matter of faith. This undermines internal coherence, objectivity, and resilience to critique. The system is not a rational ontology but a theological artifact disguised in philosophical language.

Trade-offs / Tensions (Revised):

Leibniz achieves metaphysical elegance by smuggling faith into the basement of his system and presenting a rationalist facade to the world. Classical theism, by contrast, admits its faith foundation openly and scores higher on grounding as a result. Leibniz's pretense to rational philosophy — while relying on the same doctrine of creatio ex nihilo — is what undermines his internal coherence, objectivity, and resilience to critique. The trade-off is between honest theology and dishonest philosophy.

5. Recommendations (Revised)

1. Acknowledge the foundation. Any serious engagement with Leibniz must begin by naming creatio ex nihilo as an article of faith, not a rational principle.
2. Reassess grounding claims. Future assessments should not treat Leibniz as a rational ontologist but as a theologian working in philosophical vocabulary.
3. Compare honestly. Comparative work with other ontologies should foreground the faith foundation rather than burying it in footnotes.
4. Learn from classical theism. The contrast with classical theism demonstrates that admitting a faith foundation openly is more intellectually honest — and yields higher OMAF scores on grounding and objectivity — than hiding it behind a rationalist facade.
