What’s Your Datum?

I was talking to the steel fabricator recently on a multi-story project where I was designing the stairs for them, and their detailer told me, “Hold off on the stair calcs; there’s gonna be some changes coming.” What were the changes? The architect had used the wrong datum, or elevation reference, to match up the floors of this 3 story  expansion with the existing 5 story building it would be attaching to. In so doing, each of the floors, as well as the total height of the expansion, would be over 1 foot short. Fortunately, it was caught before steel was fabricated and shipped to the site. And as far as errors go, it could’ve been worse, in that most of the framing wouldn’t change. The floor plans would stay the same, the heights between floors weren’t affected – just the total column heights and the distance from the foundation to the first elevated floor. For me, the stairs would get longer on the first 2 flights, but otherwise a minimal impact at that stage. But if they’d tried erecting the steel with everything fabricated based on the wrong datum, none of the connections to the existing building would’ve lined up.  One simple assumption in their Revit building model would’ve been an expensive fix at that point.

This got me thinking. What datum do we build our lives on? Are we making assumptions that will cost us dearly later? Will we recognize those errors before it’s too late? One “reference datum” of special importance in our lives is our assumption of God’s existence or non-existence. This has dramatic ramifications in all areas of our lives because it is a foundational assumption. However, sometimes we don’t see those effects without careful investigation. For instance, in the project I had, the floor to floor heights on the upper levels were unaffected. If they had managed to finish building with that error incorporated, you wouldn’t notice it out in the middle of the 2nd or 3rd floor. Likewise, atheists often feel that they don’t need God to live a “good” life. In their day to day lives, they may feel there’s no real difference. The problem is that their worldview is missing some support. What would happen if we went down to the ground level of atheism and inspected its foundation? Under western atheism, we’d find some Bibles stuck under their “columns” as shims! Yes, to be livable (in a civilized manner), atheism has to be shimmed up by blocks of Christianity (or at the very least theism, but more typically Christianity).[1] Yet these are the very foundation blocks atheists try to demolish. For instance, an atheist can choose to ignore the fact that truly fair, objective judgement between humans requires a 3rd party outside of humanity (i.e. God). But when they succeed in removing that idea from the culture around them, they unintentionally undercut their own life structure. Atheists can try to ground their treatment of others in concepts like “human flourishing”, but only the God of the Bible gives us a reason for why we should treat others with dignity: we are made in God’s image – His unique creation – and we have intrinsic worth because of that. So even if I flat-out hated somebody, even if they were absolutely cruel to me, they are still a living soul made in God’s image, whom He considered worthy of Jesus’ sacrifice on the cross on their behalf. Then, whether or not they deserve my kindness, whether or not humanity flourishes because of my kindness to them, and whether or not it improves the situation any, there are grounds for treating that person with kindness, respect, and love. I’m not saying atheists can’t behave well, and do wonderful things, but at some point, in your personal relationships, where general abstract philosophizing becomes very real and messy, you could care less whether humanity flourishes if it means suffering some wrong you deem “too far.” Like with Corrie ten Boom forgiving her Nazi concentration camp guard, only God can provide a foundation capable of bearing all things and enduring all things [1 Cor 13:4-7].

What are you assuming as a “given” in your life? Have you investigated that to confirm what you’re building your life on? I’ve used terms like “assumption” and “given” today to describe our different worldviews, because that is how many people arrive at them. But don’t be content to stay there, living an unexamined life. Just like with the datum on the project I was working on, you too can investigate and determine whether the datum of your life is correct or not. I’ve highlighted several lines of reasoning on this site in the past to help show how God fulfills critical requirements for any valid reference datum in life. The moral argument shows God is necessary for objective morality. The cosmological argument shows how God is necessary to provide the singular beginning of all space and time that science predicts. The argument from design shows show God is necessary to explain the intelligent and purposeful contingency we see in our universe. And the ontological argument shows how God is necessary based on the very nature of existence. Dig deep, investigate, don’t be afraid to ask tough questions, and follow the evidence where it leads. In the end, you’ll find life makes a lot more sense with God as your absolute reference.


[1] Western atheists would do well to study the history of the USSR and communist China to see atheism carried closer to its conclusion, in grand scale, than perhaps anywhere else on earth. The tens of millions dead (some estimates say over 100 million) show that ideas like atheism can have very tragic and uncivilized consequences.

Foundational Assumptions

There’s a saying about what happens when you assume, but the fact is that we all have to make assumptions at some point. You can’t build a structure without some baseline support like footings or piers; and you can’t build a theory, a philosophy, a worldview without some basic assumptions. In engineering, a common assumption is that a few test borings on a job site will inform you of the soil conditions across the site enough to complete your foundation design safely. We assume uniformity unless the test borings indicate otherwise. Some of the areas of my state are notorious for holes and caverns called karst formations. A geotechnical engineer colleague told a group of us of one case of a test boring showing solid rock about 10′ from a proposed footing location, only to pour the concrete footing and not fill up the hole. The reason: the concrete dumped in the hole had broken through the roof of a previously unknown small cavern…. Site uniformity is sometimes a very inappropriate assumption. Hopefully, like good structural foundations, your foundational assumptions for your beliefs are well-grounded. For instance, whether you believe that objective truth exists will determine a great deal of what you can reasonably believe. I say “reasonably” because one can, of course, believe whatever one wants, but if you want to hold reasonable views that are not self-contradictory or absurd in their actual application, then you need to have good foundational assumptions.

On what do you build your worldview? Relativism is the view that truth is relative to each culture, time, or even to each person in some forms. It is a lot like soil sensitive to a process called liquefaction. It seems to support weight alright when things are good, but when an earthquake hits, it turns to quicksand and provides absolutely no support. Scientism, the idea that science, or more specifically, the scientific method, is the only way of knowing truth, is a lot like those problematic karst formations. The scientific method, and science in general, is rock-solid in its area of applicability. Where it’s dangerous is when used outside of those areas. Science is great at describing stuff in the natural world, at telling us what is. My whole career as an engineer is predicated on science’s correct descriptions of the way the natural world works. Where it falters is when it’s asked to prescribe, to tell us what ought to be. We can do social experiments to see if people are selfish or mean or hateful, but science can’t tell us why they ought not be that way. In the areas it was designed to be used, science is trustworthy, but outside of those areas, it’s like building on Swiss cheese. Atheism and secular humanism often go together, as one denies God while the other elevates man to God’s position of ultimate authority. Yet this has turned out to be like building in a swamp full of peat and other “compressible material”: the higher one tries to build, the more weight one puts on the foundation, and the more it sinks. As the last century’s experiments in Communism – which were solidly and proudly atheistic – proved, man without God makes for a foundation of morality that sinks to frighteningly awful depths. Is there anything solid we can build a philosophy of life on?

There’s a saying that to build high, you have to dig deep. In other words, a house may be able to sit on a simple slab-on-grade, but a skyscraper will often have foundations going several stories underground. And when you dig down and hit something solid like Manhattan bedrock, you have the makings for some of the tallest buildings in the world. When building your framework of beliefs, some ideas will be necessarily self-limiting. They simply can’t hold up under examination. On the other hand, the Christian worldview is able to encompass all of reality because it is uniquely authored by the Creator of all reality. That is why Jesus was able to compare those who heeded His words to those building on rock:

“Therefore everyone who hears these words of Mine and acts on them, may be compared to a wise man who built his house on the rock.  And the rain fell, and the floods came, and the winds blew and slammed against that house; and yet it did not fall, for it had been founded on the rock. Everyone who hears these words of Mine and does not act on them, will be like a foolish man who built his house on the sand. The rain fell, and the floods came, and the winds blew and slammed against that house; and it fell—and great was its fall.”
– Matthew 7:24-27, NASB.

Build smart. Build your life on the only solid rock – Jesus Christ.
