Notes on C. S. Lewis and Science

As I read him, Clive Staples Lewis (1898-1963), probably the most famous Christian apologist of the 20^th century, presented a four-step apologetic. I want to note in what ways this apologetic engages science with Christian faith. Though the final step argues that Jesus is God—which is not strictly speaking a scientific concern—the first three steps confronted the scientifically based philosophy of his early 20^th century Oxford. I could also argue that they resonate into 21^st century American culture as well. 

But I’ll restrain myself on that last point. Instead, let me outline those first three steps:

1. First of all, there is more to the world than just material stuff. Materialism (that there is just brute matter) is in fact self-defeating because, if we are pure materialists, rational thinking is impossible. Lewis’s book Miracles principally presents this apologetic, but it is scattered throughout his writings, especially in the ‘40s.
2. Human beings seek something that this world cannot satisfy, which points to a God beyond this world. “If I find in myself desires which nothing in this world can satisfy, the only logical explanation is that I was made for another world.”  This argument appears in The Problem of Pain and in “The Weight of Glory.”
3. There is a Law or Rule about Right and Wrong (or the Law of Nature, or even natural law) that exists in all human beings and points to the God created that law within us. Lewis developed this apologetic in his opening Broadcast Talks for BBC, which became the first section or “book” of Mere Christianity, as well as his 1943 Riddell lectures later published as The Abolition of Man.

      

Let’s look at #2 for a moment: Lewis’s argument from Joy or desire. The argument brings to mind the question of whether Albert Einstein’s words about “God” were really about, well, God, such as “everyone who is seriously involved in the pursuit of science becomes convinced that a spirit is manifest in the laws of the Universe—a Spirit vastly superior to that of man.” Richard Dawkins argues (not surprisingly as the arch-atheist) that this stuff in Einstien isn’t really about God, it’s about transcendence. In his recent book, scientist Amir D. Aczel, contends (as I understand him) that, no, this is really about the Deity, and in fact, believing in God is profoundly compatible with science.

      

So I'm going to set Lewis in this fray. What is he saying? Is he arguing that this sense of transcendence—or better, this desire for it, which Lewis calls “Joy”—proves God? No, at least not as a deductive proof. Instead Lewis is making a suppositional argument here: We do not fully understand the desire for something beyond (or Joy) itself, but it opens to a wider metaphysical conclusion, one that points to God who created us. Or more systematically, the form of this suppositional argument from desire proceeds as follows: Suppose God created this world, we can imagine that God would leave a desire for more than this world offers. We experience a longing for more than this world offers. It is reasonable to see this as pointer to God.

      

In a certain sense then, the argument cannot be decided on the basis of science or not. Science seeks to understand the interactions of the material world. And yet, many scientists, because they focus their lives on the interactions of the material world, believe that this world is all there is.

      

Like my title says, these are notes. Nothing fully conclusive yet. But I’m interested to know what you think…
