The Cosmological Proof. The term applies technically to any argument for God through reflection upon the natural world. But most often "cosmological" refers to sweeping generalizations about ultimate origins and why the cosmos exists at all. Evolutionary schools of thought do not entertain such notions because they fall, by definition, outside what can be observed or tracked. If such questions are never asked, of course, they require no answer. Bertrand Russell once remarked in a BBC debate that the universe is "just there, and that's all." He was convinced that "all the labors of the ages, all the devotion, all the inspiration, all the noonday brightness of human genius, are destined to extinction in the vast death of the solar system."

The classic cosmological inquirer was Thomas Aquinas (1224-74), and the classic modern innovator is Canadian Jesuit Bernard J.F. Lonergan, whose "transcendental Thomism" in Insight (Philosophical Library; $10) justifies Aquinas to the modern world through a complex philosophy of human understanding. Chicago's Mortimer Adler has long been interested in Aquinas' thought. Though not formally religious he nonetheless pondered the God problem for most of his 75 years before writing his readable How to Think About God.

Aquinas reasoned that each effect must have a cause and that an endless chain must proceed back to a primordial First Cause or Prime Mover. In How to, Adler rejects that starting point because a universe with a beginning presupposes the Creator that it seeks to prove. Therefore Adler assumes that the universe had no beginning. He also rejects the idea that a higher cause underlies and explains all phenomena in the universe, on the ground that natural processes provide sufficient explanation.

That leaves the most esoteric of Aquinas' "five ways" of proving God, from "contingency." Things can be divided into two categories: "contingent" ones that could either exist or not exist, and "necessary" ones that cannot not exist. The latter is a category of one, namely God. The reason that anything at all exists, cosmologists argue, is that there must be a "necessary" being.

At one time Adler embraced Aquinas' proof, then for decades he thought it did not work because although everything in the universe is contingent, nothing ceases to exist absolutely (e.g. burning wood only changes form), so no God is needed to explain the existence of contingent things. Last May he suddenly changed his mind again after applying the "possible worlds" approach. Adler speculated that the universe is only one of many possible universes, any of which —including this actual universe—can just as easily not exist as exist. The universe is "radically contingent," the only thing capable of not existing and leaving behind absolutely nothing. An "efficient cause" is needed to explain "the actual existence here and now of a merely possible cosmos," something that preserves it in being and prevents it from being replaced by nothingness. Color that cause God. Philosopher Ross contends that this interesting argument was stated more successfully in the 13th century by his hero, Duns Scotus. Adler does not think so.
