Every engineering effort is shaped by, and in turn shapes,

the culture, politics, and times in which it is embedded. Henry Petroski

 

No one wants to learn by mistakes,

but we cannot learn enough from successes

to go beyond the state of the art. Henry Petroski

 

Good judgment is usually the result of experience. And experience is frequently the result of bad judgment. But to learn from the experience of others requires those who have the experience to share the knowledge with those who follow. Barry LePatner

 

The requirements for design conflict and cannot be reconciled. All designs...are in some degree failures, either because they flout one or another of the requirements or because they are compromises, and compromise implies a degree of failure. Failure is inherent in all useful design...because all requirements of economy derive from insatiable wishes.... It follows that all designs for use are arbitrary. The designer or his client has to choose in what degree and where there shall be failure.... if you vary the terms of your compromise—say, more speed, more heat, less safety, more discomfort, lower first cost—then you vary the shape of the thing designed. It is quite impossible for any design to be “the logical outcome of the requirements” simply because, the requirements being in conflict, their logical outcome is an impossibility.

INTRODUCTION

The Vatican newspaper last week stated plainly that “Intelligent Design” is not science. This, of course, is not news. Over 20 years ago I took a class in Evolution at a Roman Catholic university which prided itself on the rigor of its science curriculum. There, the idea that natural selection might be incompatible with religion would have been laughable.

 

But it’s not laughable when sectarian religion threatens to undermine science education in the name of teaching “a diversity of competing theories.” It tangles us free speech advocates in rhetorical knots. Happily the courts have found once again that creationism in any disguise does not belong in the public school science curriculum.

 

Now that that’s settled, what’s left to say about “Intelligent Design?” Quite a bit, actually. And getting the very tangible public policy issue out of the way (for now) might make it a little easier to open ourselves to some theological speculation on the topic.

 

Design. Could the nature of “design” point us toward an understanding of the nature of the divine? I think it may. So today we turn to engineering – a rich source of insight located at the crossroads of science and art, blending lofty theory with humbling real-life application. Yes, if we’d like to know about intelligent design, what better source of first-hand experience and hard-won wisdom could there be than those who design? In fact, engineers and architects may point us not only toward a better understanding of god, but toward a better understanding of the possibilities and responsibilities of human freedom.

 

And after the service today, the Building Scope Task Force has asked Dan Helwig of Design Unlimited to present updated drawings and answer questions regarding our building renovation. We’ll meet in the sanctuary a few minutes after the service.

 

CHILDREN’S FOCUS

How many of you like to write/type? How many of you are familiar with Shakespeare? (Poet, playwright....) Do you think you could write like Shakespeare? You never know. It’s been said that an infinite number of monkeys with an infinite number of typewriters would eventually re-create all the poetry and plays of Shakespeare. How many of you are descended from monkeys?

 

Maybe you could help me do an experiment. Even though we probably don’t have time today for an infinite number of repetitions.... Let’s check something out. The theory of natural selection states that some creatures are more likely than others to pass on their genes to succeeding generations. My hypothesis is that I would be more likely to pass on my genes if I had a better haircut.

 

If that thing about monkeys is true, then an infinite number of monkeys giving me an infinite number of haircuts would eventually make me look like Brad Pitt.... Let’s find out.

 

[At this point I passed out a dozen pair of scissors and urged the kids to cut my hair. I was dismayed that they wouldn’t do it!]

 

READING     from To Engineer is Human: the Role of Failure in Successful Design,

                        by Henry Petroski

Each opportunity to design something new... presents... choices that may appear countless. The engineer may decide to copy... good features from existing designs that have successfully withstood the forces of man and nature, but he may also decide to improve upon those aspects of prior designs that appear to be wanting....

 

The choices of design are ultimately like the choices of life. While the engineer can pursue on paper...many different designs that fulfill the requirements of a [project]...only one design can be chosen to be built, just as...only one route can be taken on a single trip from Chicago to New York no matter how many are considered in the planning.

 

Deciding which paper design will be cast in concrete presents the designer or the selection committee with a problem not unlike that faced by Robert Frost:

 

Two roads diverged in a yellow wood,

And sorry I could not travel both

And be one traveler, long I stood

And looked down one as far as I could

To where it bent in the undergrowth;

 

Two roads diverged in a wood, and I—

 

MUSICAL MEDITATION

 

MESSAGE

The concept of “Intelligent Design” includes an assumption that a conscious and well-meaning creator put all-this together. I’d like to describe some alternative ways of looking at creation, meaning, purpose, and all-this. I’m not going to try to squash the concept of a conscious and well-meaning creator. After all, this is not science and not disprovable. I’m simply going to explain that many of us who describe ourselves as humanist, atheist, or agnostic... or theist but with a naturalistic theology or a process theology ...how it is that many of us live without faith in a well-meaning creator capable of putting his or her or its intentions into practice... but lacking this particular faith does not mean that we lead empty lives devoid of meaning.

 

***

What is our purpose in life? And where does that purpose come from? When bad things happen, do they happen for a reason? Does the universe itself have an intention, a “why?”, a goal toward which we are being carried?

 

Yes and no.

 

I mean, “yes” – there is meaning and purpose in life to the extent that we recognize meaning and purpose.

 

And I mean, “no” – there does not need to be some single external original consciousness that created all meaning and purpose. Maybe there is, maybe there isn’t, but I have no experience with any force – either within or outside of nature – which consciously wills for things to happen as they do.

 

I’ll say now, for the last time today, that I’m speaking about my personal theology. I don’t know, I cannot verify empirically, that the traditional Western notions of God – a power both conscious and capable – I cannot demonstrate that these notions are false. So whatever your theology, you are welcome here. Whatever your theology, I hope that you will express yourself openly here. My theology is probably different from that of anyone in this room, but our differences do not need to interfere with our sense of mutual respect.

 

***

So, why are we here? That depends on what the definition of “Why” is. A great kids book from the 1950’s is called, A Hole is to Dig [by Ruth Krauss]. It contains such simultaneously mundane and profound observations as: “A hole is to dig.... a face is so you can make faces.... dishes are to do.... grass is to cut.... a door is to open.... a door is to shut....

 

The world is so you have something to stand on....

 

The point, I think, is that the question, “Why?” can be answered a lot of different ways. When asked “Why am I here?” I could talk about how I got here physically. Or, what I’m intending to do right now. Or, I could speculate as to some larger cosmic purpose for my being.

 

And even though I don’t believe that my being here, now, was intended and predetermined – neither by god nor by fate nor even by natural law, I still believe my life has purpose. I can quote Annie Dillard with complete sincerity:

"We are here to abet creation and to witness to it.... To notice each other’s beautiful face and complex nature.... So that creation need not play to an empty house."

 

With or without belief in a cosmic consciousness, I can sing praises to the wonders of creation in the words of Evi Seidman:

“It’s a good thing I’m not in charge here. I could never have thought of a pine cone or a pomegranate or a porcupine. And even if I’d thought of one, how on earth would I have engineered a comet or organized life in a pond?”

 

These songs of praise are beautiful in themselves. And they are all the more beautiful in that a traditional theist, and someone who resonates with process theology, and someone who rejects the notion of God altogether... might all affirm and find meaning in these love songs directed toward the unfathomable wonders of creation.

 

In brief: Process theology is a view of the divine as unfinished. There are many variations on this theme but essentially they are understandings of a higher power which is in-process, unfolding, emerging, becoming further revealed... in every moment... in relation to a changing creation.

***

I find meaning in process theology because I have observed parallel patterns in biology, in human history, and in the history of my own consciousness.

 

Here’s one of the patterns: Every day I make choices based upon my values. And over time, these choices become my values. So, which came first, the chicken... I mean the choices...or the values? What I choose and do is inseparable from what I believe or who I am. This is the case for any individual, any organization, any nation...and for human history as a whole.

 

Beliefs and actions are chickens and eggs. There’s no point in trying to determine which came first. And, there are limits to how much we can predict or control regarding what will be born of our beliefs and actions...several generations down the line.

 

So we have this and only this: our own moment in history. This day of choices. This day of compromises to be made among competing values. All day today we will be compromising – juggling our safety, our economy, and style. We will engineer, we will design our own unfolding lives. And -- as it is with every design project – we will face limits. We won’t start today from scratch. We won’t choose from among infinite resources. Our life projects may not defy the laws of nature. So we will choose – we have free will – but there’s a limited scope within which we will choose.

 

Our scope will be limited in part by nature. Our scope will be limited in part by what other people have chosen. And our scope will be limited in part by what we have chosen before.

 

But still, we will choose. And as we do, we will find ourselves designing and assembling, re-designing and re-assembling our own lives...and the lives of others...and life on this planet.

 

How incredibly presumptuous we will be: to re-assemble nature. To play God. But it’s unavoidable. With every medical decision, we intervene in the trajectory of the cosmos. When we eat, or exercise, or procreate, or teach, we affect the outcome of the world around us. At least for a while.

 

How presumptuous of us to make these calculations – sometimes consciously, sometimes unconsciously! Calculations about the value of  human life – whether we sell insurance or buy insurance we’re making these calculations.

 

And we “evaluate” time – what is it worth to “save time”? Every moment we’re bartering – comparing and exchanging one thing of value for another. Style, comfort, safety, convenience, longevity, tradition, our individual preferences vs. the “needs” of our families or society. What is each of these worth? We only know by how much of something else we’ll trade.

 

How presumptuous to have any values whatsoever! Yet we are condemned to responsibility as surely as we are inalienably free.

 

Exhausting – and invigorating – isn’t it?

 

***

Engineers do not have inherently better values than the rest of us. But they are very very good at pointing out where choices need to be made. Since they cannot create any thing or any process which will completely satisfy all of our competing values, they point out the various links in the web, so that we can make informed choices about which link we will allow to be the weakest.

 

A simple example is our shoestrings. If we were willing to sacrifice more money, comfort, and convenience, we could buy woven steel shoestrings or some other contraption which would never break. Well, of course, it would eventually break, but maybe not for several generations. But we compromise on relatively sturdy, relatively inexpensive, relatively attractive, relatively convenient means for keeping our shoes on our feet.

 

Which part will we allow to be our weakest link? Whether in our machines, our homes, our bodies, or our morning rituals, we accept the risk of failure and we make compromises.

 

Where we wish for less risk, we create redundancy – back up systems. We can live with nylon shoestrings because the consequences of breakage are relatively minor. The consequences of running out of toilet paper at the wrong time, however, are more severe. Still, we can live with a toilet paper roll that’s only a few inches thick because it’s easy to keep another roll close at hand.

 

Some of us keep one roll close at hand. Some of us keep 24 rolls close at hand. Consciously or unconsciously we choose our weakest links.

 

Our most intelligent choices are made when we know our limits and, where possible, we create backup plans, and where we keep a number of diverse options open so that when one plan fails there are others at hand that may adapt well to the changing situation.

 

Long-lasting highways and buildings and widgets and operational systems have alternate load paths. On the World Wide Web, if one traffic path is busy, the little bits of information making their way to our computers will jump off to another path... take a short cut through Canada or Uruguay for a few seconds before winding their way to Wausau.

 

Effective auto traffic management is similar; as is the management of the guests at your party, or the weight on your sore knee. In a good system, when one supportive member temporarily fails, another member picks up the burden. And in this way catastrophic failure is avoided.

 

For a while.

 

From this perspective, then, failure can be a good thing. That is, if our systems are flexible and diverse enough, minor failures can help us to spot a weak link before the whole system collapses.

 

Of course, there are limits to how much backup you can have in any system before the backup itself gets unwieldy, and counterproductive. There are limits to how strong you can make something before it gets rigid.

 

Politics, ethics, business management, parenting, any relationship, even spirituality: all involve making intelligent compromises between too much structure and support... and not enough.

 

***

Cracks. Cracks in a structure or system are not always cause for immediate alarm. But cracks left unaddressed will eventually lead to failure as tiny cracks coalesce into larger ones, as weaknesses or excessive loads continue, or as we overcompensate in one area... to the point that even an ordinary load is unbearable.

 

To be safe, since the equipment to detect cracks has limited sensitivity, it must be assumed that there are cracks in everything. In our tires, airplanes, nuclear power plants and missile defense shields. There must be cracks in our lives.

 

We can respond to this reality with denial and hubris – overconfidence which leads to catastrophic failure. Or, we can respond intelligently and conservatively.

 

An intelligent, prudent, conservative response to cracks and weakest links is to inspect regularly (our physical stuff as well as our intangible internal stuff.) We can perform maintenance procedures regularly. We can overdesign – that is, we can always plan with a margin of error. And we can prepare for the worst case scenario.

 

Of course, even when we do all of these things, there are no guarantees.

 

***

The transition in engineering from slide rule to calculator to personal computer has been a risky one. In the days of the slide rule, a person had to know if the answer they came up with was reasonable. If it was within the range of possibility. One risk with calculators and computers is that we get answers to such incredible precision that we may be fooled into assuming the answers are accurate.

 

These kinds of ungrounded calculations can give us false sense of security. We can slip into unsafe assumptions and dangerously lower our margins for safety.

 

The computer has done wonders for design in that it enables us to see where we have been overdesigning. In earlier days of engineering, for example, things would be made excessively strong and heavy and expensive... things that today’s engineers can more easily optimize and pare down to their essentials.

 

The danger is that computers can help us to find the lightest, cheapest, fastest ways to build, but they don’t (yet) have the essential human trait of suspicion.

 

We still need human engineers, human observers, human decision-makers to consider how a structure or a system might fail. Because (at least so far) only humans can choose how the structure will be used and see what forces will be acting upon it.

 

This is why experience is so essential.

 

Hubris is overconfidence which leads to catastrophic failure. We saw some engineering hubris earlier this month in the collapse of a German skating rink...and in the collapse of a coal mine, and in the fire in another coal mine. We see plenty of hubris in  religion, manifest in violent suppression of spiritual expression. There is hubris in math & science manifest in the lack of understanding about the limits of pure reason; and a growing hubris in ignorance – that is, an astonishing pride in anti-intellectualism, and mistrust of those with experience.

 

***

All failures are ultimately failures of design – even if the more immediate cause of failure is poor construction, or poor maintenance, or natural disaster. In all cases it is the designer’s responsibility to anticipate and design to prevent failure or to get the product off the market before failure occurs.

 

The hubris of the “Intelligent Design” movement is that it assumes a once-and-for-all answer to all future questions. It requires it’s adherents to abdicate responsibility, give up making observations and judgments. No matter how contradictory the evidence, the answer is always the same. “Because the good Lord made it that way.”

 

Dan Helwig’s firm is called Design Unlimited. Who is he trying to kid? Neither he nor his firm are unlimited. The contract we will sign with him makes it very clear – and appropriately so – that there are limits to his responsibility. So if, as I said a moment ago, if the designer is ultimately responsible for everything, and Dan is not ultimately responsible for everything...then who is the designer?

 

I doubt that the designer is a conscious and well-meaning creator. If that were the case, then we would have to blame God for everything that happens. As handy as that may be, it doesn’t contribute much to motivate us toward making responsible, intelligent choices.

 

So, what if it’s us? What if we  are the designers? Or, what if we’re really in partnership with Dan... and in partnership with the universe?  It may sound audacious, it may sound presumptuous, and it may be inescapable.
