Matt Dillahunty on The argument from design
Dillahunty argues the design argument is a textbook argument from ignorance — we don't know how something arose, therefore God must have done it.
Matt Dillahunty has addressed the argument from design hundreds of times on The Atheist Experience, and his response is honed to razor sharpness. The design argument, he contends, commits a classic logical error: it confuses the appearance of design with actual design. Human beings are pattern-recognition machines, evolved to detect agency even where none exists — which is why we see faces in clouds and purposes in natural processes. The appearance of design in the natural world is real, but the inference to a designer is unwarranted.
Dillahunty is particularly effective at identifying the argument's hidden assumptions. When a caller argues that DNA is too complex to have arisen naturally, Dillahunty asks: how do you know? What is your model for calculating the probability of DNA arising without a designer? The answer, invariably, is that the caller has no such model — they are simply asserting that complexity implies design because it seems intuitive. But intuition, Dillahunty insists, is not a reliable guide to questions of cosmic origins.
He also presses the regress problem with characteristic directness: if complex things require a designer, then God — the most complex thing imaginable — requires one too. If God can be complex without a designer, then complexity does not, in fact, require a designer, and the argument refutes itself.
“The argument from design is really an argument from personal incredulity. You can't imagine how something could arise naturally, so you conclude it didn't. That's not an argument — it's a confession of ignorance.”
