The Ontological Argument

Can reasoning about the idea of God lead to a claim about God’s existence? The ontological argument raises that question. This reflection considers the place of philosophical reasoning alongside Christian faith and experience.

The Ontological Argument: God as the Greatest Conceivable Being

Anselm’s ontological argument asks whether a being greater than which none can be conceived could exist only in thought. His proposed answer is no. Philosophers continue to dispute the reasoning; imagining something perfect does not by itself establish its existence.

An objection: concept and reality

Atheists frequently challenge the Ontological Argument, claiming it is flawed because merely defining a perfect being does not guarantee its existence in reality. They argue that the ability to imagine a perfect being does not necessitate its existence beyond our thoughts, suggesting that the argument conflates conceptualization with actual existence.

Supporters distinguish an ordinary imagined object from a being whose existence they take to be necessary. That distinction is central to their response, but the step from a concept to reality remains disputed.

The treasure-chest image helps us notice the difference between thought and reality. It cannot establish that a greatest conceivable being exists.

Mathematical examples can invite reflection on necessity, but they do not settle whether God necessarily exists. Genesis 1:1 expresses the biblical confession of a Creator; it is distinct from a philosophical demonstration.

Kant’s objection about existence

One notable critique, famously presented by philosopher Immanuel Kant, posits that existence is not a predicate. Kant contended that existence does not serve as a defining characteristic like dimensions or color. According to his reasoning, defining God as a perfect being does not logically necessitate God's existence, since existence is not a trait that contributes to something being "perfect."

Some defenders reply to Kant by appealing to necessary existence rather than treating existence as an ordinary property. Whether that reply succeeds remains a philosophical question.

An imagined bridge cannot carry us across a river. That picture illustrates a difference between conception and reality, without proving that God exists.

The Importance of Perfection and Existence

The disagreement remains: can necessary existence belong to the idea of the greatest conceivable being, and does the argument establish reality beyond that idea?

Psalm 14:1 speaks from Israel’s faith about denial of God and wrongdoing. It should not be used to assign corrupt motives to every person who questions an argument.

Carrying this into life

The ontological argument invites reflection on perfection, necessity, and existence. We can examine it patiently while hearing the objections fairly.

As we look at the philosophical discourse surrounding God's existence, it is vital to recognize that these discussions transcend mere academic interest. They lead us to profound insights about the essence of reality and our connection to the Creator. "In Him we live and move and have our being" (Acts 17:28), and through these philosophical inquiries, we enhance our comprehension of a God who is not only a concept but also a tangible and present reality.
