Scientists ‘Prove’ God Exists Based on Principles of Modal Logic

Scientists ‘Prove’ God Exists. Two scientists have formalized a theorem regarding the existence of God penned by mathematician Kurt Gödel. But the God angle is somewhat of a red herring — the real step forward is the example it sets of how computers can make scientific progress simpler.

As headlines go, it’s certainly an eye-catching one. Scientists Prove Existence of God, German daily Die Welt wrote last week.

But unsurprisingly, there is a rather significant caveat to that claim. In fact, what the researchers in question say they have actually proven is a theorem put forward by renowned Austrian mathematician Kurt Gödel — and the real news isn’t about a Supreme Being, but rather what can now be achieved in scientific fields using superior technology.

When Gödel died in 1978, he left behind a tantalizing theory based on principles of modal logic — that a higher being must exist. The details of the mathematics involved in Gödel’s ontological proof are complicated, but in essence the Austrian was arguing that, by definition, God is that for which no greater can be conceived. And while God exists in the understanding of the concept, we could conceive of him as greater if he existed in reality. Therefore, he must exist.

Even at the time, the argument was not exactly a new one. For centuries, many have tried to use this kind of abstract reasoning to prove the possibility or necessity of the existence of God. But the mathematical model composed by Gödel proposed a proof of the idea. Its theorems and axioms — assumptions which cannot be proven — can be expressed as mathematical equations. And that means they can be proven.
