Design Defined

Engineering_design_drawings smallI’ve heard a lot of criticism of “intelligent design” (ID), the idea that certain features of the universe and of living organisms are best explained by an intelligent cause rather than unguided naturalistic processes. But I have to ask, regarding intelligent design, is there any other kind? If we see the appearance of design, is there any other explanation besides intelligence? Let’s first define design. Design is a very broad task, with lots of different types, but a good (if somewhat laborious) definition is:

A specification of an object (or process), manifested by an agent, intended to accomplish goals, in a particular environment, using a set of primitive components, satisfying a set of requirements, subject to constraints.

That could really apply to things as diverse as engineering or developing a new soup recipe, but let’s break that down with an example.  I’m an engineer, so here’s an example from an actual job I worked on earlier this year that illustrates each of these criteria. I (the agent) designed a chevron brace connection (the object) to resist a 665,000# earthquake force (the goal) in Little Rock, AR (the environment) using steel tubes, gusset plates, bolts, & welds (the primitive components) to satisfy the 2006 International Building Code (the requirements) without obstructing a doorway (a constraint).

This example is representative of a typical design, but it’s simply not something we see occurring without intent. We don’t accidentally design things.  Water may erode the Grand Canyon, but wind and rain don’t hit the Black Hills of South Dakota with intent to sculpt giant faces into the cliffs. Erosion causing Mount Rushmore is not a reasonable theory! We recognize the design of Mount Rushmore and understand that someone designed it, even if we don’t know who (Gutzon Borglum in that case).  So back to the original question. Is there any other kind of design besides intelligent design? Not really, and here’s why.  Two things jump out from the above definition: an agent, and a goal.  The components, environment, requirements, and constraints add to the definition, but the heart of any design is a person with a purpose. And purpose is not a characteristic of chance or even “natural selection”. It is the result of choice, and choice requires intelligence. Rocks, trees, bacteria, the wind, a piece of steel – none of these can have goals or plans on their own. Only sentient beings can do that. So it seems that design requires intelligence by definition.

Interestingly, Richard Dawkins wrote that “Biology is the study of complicated things that give the appearance of having been designed for a purpose.” Here the Christian and the atheist agree on the presence of appearance of design in nature. Basically, the atheist argument is that this evidence is a false positive, an indication of design when there isn’t any, while the Christian claims that our observations are accurate and the appearance of design is, in fact, indicative of actual design. So at what point do we say, “If it walks like a ducks and quacks like a duck, it’s probably a duck and not a time-traveling homicidal shape-changing cyborg disguising himself as a duck, or an advanced alien holographic projection of a duck”? Much like a duck simply being a duck, I think we can say that a powerful, knowledgeable, willful Master Designer being behind all the apparent design we see in nature is a simpler and less far-fetched explanation than what we have to derive in a strictly materialistic universe. Today I just wanted to address the necessity by definition for a designer in any true case of design, and the corequisite of purpose, both of which are absent in a world governed solely by natural selection. Stay tuned as we dig into the case for actual design in upcoming weeks.
