Does God Exist? Yes, Mathematician Says

Aristotle and Descartes would be pleased to hear Dr. William Hatcher proclaim that even God Himself cannot defy logic.
Hatcher, who is a self-proclaimed Platonist philosopher with a Ph.D. in mathematics, delivered a logical proof for the existence of God before an over-filled auditorium in Warren Hall last night.
The event marked the first in what the Baha'i student organization hopes will be a series of discussions about religion, science, and philosophy, and how the three topics interrelate.
"We just felt like there wasn't enough discussion on campus" about these matters, said Natasha Bruss, BC '05, President of the Baha'i club at Columbia. Baha'i is based on the teachings of the prophet Baha'u'llah, who preached that all religions are one, religion is progressive, and that faith is not meant to be dogmatic.
Hatcher, a Baha'i adherent himself, is similarly uninterested in dogma. His discussion explored the existence of God and carefully shied away from any of its implications. Rather, he stated, "we have to transform the religious discourse from a discourse about belief to a discourse about truth."
To that end, Hatcher began his discussion with an introduction to Aristotlean, or attributional, logic and its shortcomings.
Aristotle purported to have proven the existence of God, but he did so based on a kind of logic that deals with properties of objects, an approach, he argued, that's less than satisfying considering that God's attributes cannot be perceived. Aristotle insisted that there must be a first cause, namely God, in order to avoid the logical inconsistencies of an infinite regress of causes for the universe.
Avicenna, an ancient Muslim philosopher, employed a different form of logic in his proof. He examined the relations between objects rather than their attributes, and in doing so accomplished what Hatcher called "really amazing stuff." He claimed to have proved the existence of God without recourse to Aristotle's infinite regression principle.
Hatcher said that though many subsequent philosophers like Thomas Aquinas and Moses Maimonedes built on Avicenna's proof, they continued to fall back on the infinite regression principle. Hatcher argued that this principle is not sufficient to prove the necessity of God's existence. Modern mathematics demonstrates the logical possibility of infinite regression; negative integers, for instance, do not have a minimal element or something that can be labeled a "first cause."
Thus, Hatcher has attempted to wed modern mathematics and ancient philosophy in a proof of God's existence, drawing on Avicenna's concept of relational logic. "In relational logic, we want to know how the object relates to other objects. It turns out that the relational approach often yields more useful information [than Aristotlean attributional logic]."
The proof itself rests on four principles, the first of which is the assertion that something exists. Even if the world is an illusion, he pointed out, an illusory self, contemplating an illusory universe, is still something that exists.
Further, he said, everything that exists does so because of some cause, and the "principle of sufficient reason" states that every phenomenon is either caused by something external or caused by itself, but never both. "Everything that exists has to have a reason for existing," he said.
Working from these principles, Hatcher first defined what he called "the minimum criteria for Godhood," and then set about trying to prove the existence of a phenomenon to fit those criteria. God, he said, must exist and be unique, and must be self-caused as well as being the cause of everything else. "Every existing phenomenon is the end effect of a causal chain of possibly infinite length, starting with God," he said.
He then delved into Avicenna's discussion of the part-whole relationship. "All known physical phenomena are composites, except possibly the elementary particles of quantum mechanics," he stated. Thus, if A is a component of B, then B is composite, and furthermore a composite cannot be a cause of one of its components, because it could not exist without all its components in place.
From these definitions, he said, one can infer that the universe is a composite of all phenomena. He inferred that the universe itself, then, cannot bring any of its own components into being, as it could not have existed before the existence of the components.
Then, the universe could similarly not be self-caused, since it is caused by the aggregation of its components, and so there must be some object, G, that causes the universe but is not the universe itself. G must then be universal because it is a cause, directly or indirectly, of every component in the universe.
He concluded that G is the unique uncaused phenomenon, because, as the cause of everything, it can't be caused by something else.
Hatcher said that the strength of the proof is that each assumption it rests on is empirically grounded and is "far more reasonable than its negation."
David Kline, CC '07, said he was impressed, even though he felt that the logical proof of God, far from justifying faith, only requires a different kind of faith. But, with that faith in reason so characteristic of Columbia students, he said he appreciated that the talk was "a purely logical representation of the existence of God and not the meaning of God."
