Naturalism’s Missionary Zeal

John MacArthur


naturalism's iconModern naturalism is often promulgated with a missionary zeal that has powerful religious overtones. The popular fish symbol many Christians put on their cars now has a naturalist counterpart: a fish with feet and the word "Darwin" embossed into its side. The Internet has become naturalism's busiest mission field, where evangelists for the cause aggressively try to deliver benighted souls who still cling to their theistic presuppositions. Judging from the tenor of some of the material I have read seeking to win converts to naturalism, naturalists are often dedicated to their faith with a devout passion that rivals or easily exceeds the fanaticism of any radical religious zealot. Naturalism is clearly as much a religion as any theistic world-view. The point is further proved by examining the beliefs of those naturalists who claim to be most unfettered by religious beliefs.

Take, for example, the case of Carl Sagan, perhaps the best-known scientific celebrity of the past couple of decades. A renowned astronomer and media figure, Sagan was overtly antagonistic to biblical theism. But he became the chief televangelist for the religion of naturalism. He preached a world-view that was based entirely on naturalistic assumptions. Underlying all he taught was the firm conviction that everything in the universe has a natural cause and a natural explanation. That belief--a matter of faith, not a truly scientific observation--governed and shaped every one of his theories about the universe.

Sagan examined the vastness and complexity of the universe and concluded--as he was bound to do, given his starting point--that there is nothing greater than the universe itself. So he borrowed divine attributes such as infinitude, eternality, and omnipotence, and he made them properties of the universe itself.

"The cosmos is all that is, or ever was, or ever will be," was Sagan's trademark aphorism, repeated on each episode of his highly-rated television series, Cosmos. The statement itself is clearly a tenet of faith, not a scientific conclusion. (Neither Sagan himself nor all the scientists in the world combined could ever examine "all that is or ever was or ever will be" by any scientific method.) Sagan's slogan is perfectly illustrative of how modern naturalism mistakes religious dogma for true science.

Sagan's religion was actually a kind of naturalistic pantheism, and his motto sums it up perfectly. He deified the universe and everything in it--insisting that the cosmos itself is that which was, and is, and is to come (cf. Revelation 4:8). Having examined enough of the cosmos to see evidence of the Creator's infinite power and majesty, he imputed that omnipotence and glory to creation itself--precisely the error the apostle Paul describes in Romans 1:20-22:

For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead, so that they are without excuse, because, although they knew God, they did not glorify Him as God, nor were thankful, but became futile in their thoughts, and their foolish hearts were darkened. Professing to be wise, they became fools.

Exactly like the idolaters Paul was describing, Sagan put creation in the Creator's rightful place. Carl Sagan looked at the universe and saw its greatness and concluded nothing could possibly be greater. His religious presuppositions forced him to deny that the universe was the result of intelligent design. In fact, as a devoted naturalist, he had to deny that it was created at all. Therefore he saw it as eternal and infinite--so it naturally took the place of God in his thinking.

The religious character of the philosophy that shaped Sagan's world-view is evident in much of what he wrote and said. His novel Contact (made into a major motion picture in 1997) is loaded with religious metaphors and imagery. It's about the discovery of extraterrestrial life, which occurs in December 1999, at the dawn of a new millennium, when the world is rife with Messianic expectations and apocalyptic fears. In Sagan's imagination, the discovery of intelligent life elsewhere in the universe becomes the "revelation" that affords a basis for the fusing of science and religion into a world-view that perfectly mirrors Sagan's own belief system--with the cosmos as God and scientists as the new priesthood.

Sagan's religion included the belief that the human race is nothing special. Given the incomprehensible vastness of the universe and the impersonality of it all, how could humanity possibly be important? Sagan concluded that our race is not significant at all. In December 1996, less than three weeks before Sagan died, he was interviewed by Ted Koppel on "Nightline." Sagan knew he was dying, and Koppel asked him, "Dr. Sagan, do you have any pearls of wisdom that you would like to give to the human race?"

Sagan replied,

We live on a hunk of rock and metal that circles a humdrum star that is one of 400 billion other stars that make up the Milky Way Galaxy, which is one of billions of other galaxies, which make up a universe, which may be one of a very large number--perhaps an infinite number--of other universes. That is a perspective on human life and our culture that is well worth pondering. [ABC News Nightline, December 4, 1996.]

In a book published posthumously, Sagan wrote, "Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves. [Pale Blue Dot (New York: Random House, 1994), 9.]

Although Sagan resolutely tried to maintain a semblance of optimism to the bitter end, his religion led where all naturalism inevitably leads: to a sense of utter insignificance and despair. According to his wordview, humanity occupies a tiny outpost--a pale blue speck in a vast sea of galaxies. As far as we know, we are unnoticed by the rest of the universe, accountable to no one, and petty and irrelevant in a cosmos so expansive. It is fatuous to talk of outside help or redemption for the human race. No help is forthcoming. It would be nice if we somehow managed to solve some of our problems, but whether we do or not will ultimately be a forgotten bit of cosmic trivia. That, said Sagan, is a perspective well worth pondering.

All of this underscores the spiritual barrenness of naturalism. The naturalist's religion erases all moral and ethical accountability, and it ultimately abandons all hope for humanity. If the impersonal cosmos is all there is, all there ever was, and all there ever will be, then morality is ultimately moot. If there is no personal Creator to whom humanity is accountable and the survival of the fittest is the governing law of the universe, all the moral principles that normally regulate the human conscience are ultimately groundless--and possibly even deleterious to the survival of our species.
