As we continue our series based upon philosopher Peter Kreeft's work Twenty Arguments God's Existence, this week we consider the Design Argument. Admittedly, I don't love Kreeft's formulation of the argument,1 but for those new to the idea, it is a good place to start.
Kreeft writes:
This sort of argument is of wide and perennial appeal. Almost everyone admits that reflection on the order and beauty of nature touches something very deep within us. But are the order and beauty the product of intelligent design and conscious purpose? For theists the answer is yes. Arguments for design are attempts to vindicate this answer, to show why it is the most reasonable one to give. They have been formulated in ways as richly varied as the experience in which they are rooted. The following displays the core or central insight.
2. Either this intelligible order is the product of chance or of intelligent design.
3. Not chance.
4. Therefore the universe is the product of intelligent design.
5. Design comes only from a mind, a designer.
6. Therefore the universe is the product of an intelligent Designer.
The first premise is certainly true-even those resistant to the argument admit it. The person who did not would have to be almost pathetically obtuse. A single protein molecule is a thing of immensely impressive order; much more so a single cell; and incredibly much more so an organ like the eye, where ordered parts of enormous and delicate complexity work together with countless others to achieve a single certain end. Even chemical elements are ordered to combine with other elements in certain ways and under certain conditions. Apparent disorder is a problem precisely because of the overwhelming pervasiveness of order and regularity. So the first premise stands.
If all this order is not in some way the product of intelligent design—then what? Obviously, it "just happened." Things just fell out that way "by chance." Alternatively, if all this order is not the product of blind, purposeless forces, then it has resulted from some kind of purpose. That purpose can only be intelligent design. So the second premise stands.
It is of course the third premise that is crucial. Ultimately, nonbelievers tell us, it is indeed by chance and not by any design that the universe of our experience exists the way it does. It just happens to have this order, and the burden of proof is on believers to demonstrate why this could not be so by chance alone.
But this seems a bit backward. It is surely up to nonbelievers to produce a credible alternative to design. And "chance" is simply not credible. For we can understand chance only against a background of order. To say that something happened "by chance" is to say that it did not turn out as we would have expected, or that it did turn out in a way we would not have expected. But expectation is impossible without order. If you take away order and speak of chance alone as a kind of ultimate source, you have taken away the only background that allows us to speak meaningfully of chance at all. Instead of thinking of chance against a background of order, we are invited to think of order-overwhelmingly intricate and ubiquitous order-against a random and purposeless background of chance. Frankly, that is incredible. Therefore it is eminently reasonable to affirm the third premise, not chance, and therefore to affirm the conclusion, that this universe is the product of intelligent design.2
Obviously, skeptics have offered numerous challenges to this argument over the years. Dr. Kreeft responds to 3.
Challenge #1
Hasn't the Darwinian theory of evolution shown us how it is possible for all the order in the universe to have arisen by chance?3Response
Challenge #2
Response
Just consider how in the last decades we have strained fantastically at the limits of our knowledge; we have cast our vision far beyond this planet and far within the elements that make it up. And what has this expansion of our horizons revealed? Always the same thing: more—and not less—intelligibility; more—and not less—complex and intricate order. Not only is there no reason to believe in a surrounding chaos, there is every reason not to. It flies in the face of the experience that all of us—believers and nonbelievers—share in common.
Something similar can be said about the future. We know the way things in the universe have behaved and are behaving. And so, until we have some reason to think otherwise, there is every reason to believe it will continue on its orderly path of running down. No speculation can nullify what we know.
And, anyway, exactly what sort of chaos is this question asking us to imagine? That effect precedes cause? That the law of contradiction does not hold? That there need not be what it takes for some existing thing to exist? These suggestions are completely unintelligible; if we think about them at all, it is only to reject them as impossible. Can we imagine less order? Yes. Some rearrangement of the order we experience? Yes. But total disorder and chaos? That can never be considered as a real possibility. To speculate about it as if it were is really a waste of time.6
Challenge #3
But what if the order we experience is merely a product of our minds? Even though we cannot think utter chaos and disorder, maybe that is how reality really is.7
Response
Our minds are the only means by which we can know reality. We have no other access. If we agree that something cannot exist in thought, we cannot go ahead and say that it might nevertheless exist in reality. Because then we would be thinking what we claim cannot be thought.
Suppose you claim that order is just a product of our minds. This puts you in a very awkward position. You are saying that we must think about reality in terms of order and intelligibility, but things may not exist that way in fact. Now to propose something for consideration is to think about it. And so you are saying: (a) we must think about reality in a certain way, but (b) since we think that things may not in fact exist that way, then (c) we need not think about reality the way we must think about it! Are we willing to pay that high a price to deny that the being of the universe displays intelligent design? It does not, on the face of it, seem cost effective.8
So, what do you think of the Design Argument? Do you think any of the challenges to the argument are compelling? Please feel free to share in the comments below.
Courage and Godspeed,
