The Logic of God

God Separates the Light and the Darkness – Michelangelo – 1512

In previous posts (here and here), I’ve written about the need for a clear understanding of logic to separate good and bad thinking. I’ve highlighted the fundamental laws of logic: the Law of Identity (A is A), the Law of Non-contradiction (A is not non-A), and the Law of the Excluded Middle (either A or non-A). These are so fundamental to basic thought, it’s easy to not think about them. Yet remembering these basic, self-evident truths can keep you from falling victim to  some surprisingly common mistakes in this age of relativism. Sadly, some Christians have tried to distance themselves from logic, thinking that “God is above logic”. On the contrary, the Bible reveals in its descriptions of God a rich exposition of these truths that shows that logic is part of God’s very nature.

Consider the Law of Identity. Commonly formulated as A=A, this demonstrates why these are called “self-evident” truths – you recognize the truth of it as soon as you see it. There is no proof of this because this is one of your basic building blocks of thought that you can’t break down any lower. Something simply is what it is. How is this demonstrated in Scripture? In the book of Exodus, God speaks to Moses, telling him to go and rescue the Jews enslaved in Egypt. Moses worries that the Jews, who have lived in the polytheistic Egyptian culture for centuries by this point, won’t believe him when he tells them that “the God of your fathers has sent me to you.” He supposes they may ask “What is His name?”, and asks God how he is to answer. God responds with “I Am Who I Am. Tell them ‘I Am has sent me to you.'”[1] This expression of independent, self-existent being is the epitome of the Law of Identity. We can all be identified in relation to someone else. A man may be his father’s son, or his sibling’s brother. There may be hundreds of Johns in a city, tens of John Smiths, only 2 that live on the same street, but only one John Smith Jr on that street. But here, God shows that His name can only relate Him to Himself. He is truly in a category by Himself. And we understand this by the Law of Identity.

Let’s look at the Law of Non-contradiction now. There are several different ways of expressing this, but in general, something cannot be both true and false at the same time and in the same manner. Similarly, something can’t both exist and not exist at the same time in the same way. How is this demonstrated in the Bible? The apostle John records Jesus saying that “I am the way, the truth, and the life”.  The book of Hebrews tells us that “it is impossible for God to lie”, and the apostle Paul tells Titus that God “does not lie” and Timothy that “He cannot deny Himself”.[2] Why is this important? Because logic seeks after the truth, and the opposite of truth is a lie. A lie can also be defined as a contradiction, for truth corresponds with reality, while a lie contradicts reality (a contradiction, from the Latin “contra” + “dictio” literally “speaks against itself”). So here we see that because God cannot lie, He cannot violate the Law of Non-contradiction.

The Law of Excluded Middle says that something either is or isn’t, true or false, on or off. There is no middle option between contradictory states. There are times when we may have a spectrum of choices, like when the gas tank is empty, or full, or somewhere in between. The Law of the Excluded Middle comes into play when the choice is between true opposites where one choice is the negation of the other, Instead of “empty” and “full”, the choice is between empty and not-empty, or between full and not-full. God either exists or He doesn’t. Our own belief, unbelief, or agnosticism does nothing to change that objective status. The apostle John tells us that “God is Light, and in Him there is no darkness at all.”[3] It’s either all or nothing.He either exists as morally perfect, without blemish, or not at all.

Now, is all of this to say that God is somehow limited by some man-made rules? Hardly. The laws of logic aren’t made, but discovered. Logic is the lens through which we look to make sense of reality, and it makes sense of reality because it is founded in the nature of the Creator of reality. Rather than limiting God, logic gives us a glimpse of His nature.

How to Get Away with Murder

7 half-week_embryo
Baby at 7 1/2 weeks after conception

There is a curious inconsistency in American law right now. Many states have laws stating that if a pregnant woman is murdered, the assailant will be charged with not one, but two, murders. Even if she is only injured but the fetus is killed, murder (or manslaughter) charges may be brought against the assailant for the death of the fetus. 23 of those 38 states count the killing of the fetus as murder/manslaughter at any stage of pregnancy from fertilization to birth.[1] For instance, Scott Petersen in California was charged in 2004 with 2 counts of murder after he murdered his wife who was 8 months pregnant.[2] But most of these state laws also have a very specific exception for when the intentional killing of an unborn child is not considered murder: when the person doing the killing is an abortionist. But what’s changed for this exception? What, precisely, is the difference between the criminal and the abortionist?

Is one killing and the other not? No. Clearly, the baby is alive in both cases prior to the act, and dead afterward. In the case of late-term murders and late-term abortions, the presence of detectable heartbeat, brainwaves, metabolism, and response to stimuli makes it clear that the baby is alive in both cases. The absence of these signs of life (and the dismemberment common in abortion)  makes it clear the baby is very much dead after both acts. But even in the first trimester, there are certainly enough signs of life to say the object being killed is not inanimate (fetal heartbeats, for instance, have been detected at 22-30 days after conception, brainwaves as early as 6 weeks, 2 days).[3] Even assuming the baby were just a “clump of cells” as some like to say, there is no question that they are living cells at the very least.

So both involve killing something, but is abortion killing a human? That’s really the only question that matters, isn’t it? If the baby isn’t a human, then why are are people like Scott Petersen sitting on Death Row with two counts of murder against them instead of just the mother’s murder? I’ve heard abortion compared to having a tumor removed, that they’re both just unwanted, parasitic blobs of tissue. The claim that a fetus is just a clump of cells or a “blob of tissue” is a bit of an oversimplification as the the baby is already made up of roughly 1 billion cells and has most of its adult organs formed by the time its embryonic stage is complete at 8 weeks (from conception). At best, that “blob” comparison is only valid for the first few days after conception.  Of course, the tumor alluded to would also be considered living cells, and animals also exhibit the same signs of life like heartbeat, brainwaves, breathing, and response to stimuli. So what makes this rapidly developing “clump of cells” human? First, it has human DNA, and it gets this individual-specific DNA within the first  day after conception, as 23 chromosomes from the father and 23 chromosomes from the mother are combined to form a new 46-chromosome human with all the genetic information needed to form a fully-functioning human. The degree of development doesn’t change this basic genetic criteria. It has the same DNA at 80 years old that it did 1 day after conception. Second, an adult human is the natural consequence of the development of this “blob of tissue”. While a tumor may share a person’s DNA (with certain mutations), tumor growth never results in the formation of a new person.

So it’s human. But why think this baby is a separate human? Isn’t it just a part of its mother’s body? The baby’s connection to the mother (the umbilical cord) is one of life support. If you were connected to another person for an emergency blood transfusion, would you then become part of that person? Of course not. Your dependence on the other person does not change your status as a person. One could also point to things like its unique set of fingerprints (present by 10 weeks). After all, we’ll often use these to uniquely identify a person throughout their life post-birth. Of course, the baby often having a different blood type from it’s mother and a different gender half the time clearly confirms it is not part of it’s mother’s body even though it resides inside her body. But even with the same blood type and gender, and before unique fingerprints have formed,  DNA testing will show the baby is a distinct, separate human from it’s mother as half of it’s 46 chromosomes came from the father to form a genetically unique human.

So the baby seems to be unequivocally a distinct living human. But is killing it murder? After all, murder is more than just killing. In cases of self-defense or protecting innocent life, killing an assailant is not considered murder, but justifiable homicide. Does abortion fall into this category? That is how it’s viewed in these legal exemptions for abortionists. But generally, the other exceptions have to be justified by saying that an innocent person might’ve been killed or some other serious crime would’ve been committed if the assailant hadn’t been killed first.[4] Yet, the unborn baby seems to be the very picture of innocence, having had no chance to do anything malicious to anyone that should warrant death.

In the end, we need to recognize that the abortionist is committing murder by intentionally killing a unique, living, innocent human without provocation. And what’s worse, through decades of scientifically, philosophically, and legally false propaganda, generations of women have been tricked into supporting institutionalized murder on an epic scale. I haven’t used any religious rationale in this post, just basic reasoning and science. But notice how the science supports the historic Christian position that abortion is wrong. This is to be expected if Christianity really is the true revelation of our Creator, for science is simply the observation of the physical world He has made.

Why Only One?

The Olympians by Nicolas-André Monsiau
The Olympians by Nicolas-André Monsiau

After presenting in Honduras on the evidence for intelligent design in the genetic code, and thus the necessity of a Designer of DNA (God), one observant lady asked a good question that evening. How do we know there’s only one designer? In other words, while the argument from design can bring us from atheism to theism, what’s to say polytheism isn’t really the best explanation? She’s right – the teleological argument from design that I was presenting can’t tell us if there were multiple designers, only that the design we observe required some designer. But it is quite common for any man-made project to be divided up among a design team. In fact, on almost every project I’ve worked on in my career as an engineer, I’ve simply been one member of a design team, dealing with my area of knowledge. So does the idea of a “divine design team” of gods bear up to scrutiny? I don’t think so, and here’s why.

Part of the strength of the case for the God of the Bible is the interlocking nature of the evidence. While the evidence from design doesn’t address this particular question, other line of reasoning do. First we have to look at the law of causality: everything that begins to exist has a cause. Anything that fits in this category is considered contingent because its existence depends on something prior – its cause. A design team of angels or “lesser gods” responsible for the design we see in different natural objects would simply be an intermediate link in the chain of causation. They might be immediately responsible for the objects we investigate, but if we go back far enough, we must eventually arrive at something that does not need a prior cause because it has always existed. They would ultimately need to trace back to a non-contingent source, which we would then call God.  Even if God delegated the design of nature to a “design team” and did no specific design Himself, He would still be causally responsible for whatever was designed by them.

But one might ask if there could be multiple non-contingent beings. Let’s follow that line of reasoning. To be non-contingent (or metaphysically necessary) requires eternal existence in order to not have a prior cause.  A necessary being cannot  not exist, hence the title “necessary”. So this being can never cease to exist without all of reality that is contingent on him ceasing to exist at the same time. Therefore, no other being or group of beings could be more powerful than the one in question. For if any other being(s) could control or change the subject being, then its actions would be contingent on their actions, and he would turn out to not be a necessary being after all. For these reasons, you can’t have more than one non-contingent being in any possible reality. It’s also worth noting that the axiological argument shows that God exists due to the existence of objective moral values, which have to come from a source beyond humanity to truly be objective. But if multiple non-contingent beings existed, there would not be a single source for the objective moral values we observe. This is not to say that those values couldn’t have been established by consensus of a group of deities, but that does seem to multiply assumptions needlessly. I don’t know that we could say the axiological argument alone is sufficient proof of God’s uniqueness, but I would count it as contributing evidence.

But could we have necessary beings in different “dimensions”, “parallel universes”, or some other concept of separate but coexisting realities? This is basically just an updated idea of henotheism, the idea of locally supreme deities, applied to more abstract regions than the original geographical ones. If a god were all-powerful in his dimension, but limited to that dimension, then he wouldn’t really be necessary, even in that dimension. He would be, in effect, a caged deity contingent on that dimension’s existence and the higher deity who established that dimension. A truly necessary being must transcend all possible worlds/dimensions/realities to not be contingent.

In the end, we come to the conclusion that if God exists, He must be a non-contingent necessary being in any possible reality. We can look at the teleological argument (from design) and the various cosmological arguments (from causality) to see that God exists. Then we can look at the axiological argument (from morality) and ontological argument (from being) to see that polytheism is false and the Bible is correct when it says that “there is no God but one. For even if there are so-called gods whether in heaven or on earth, as indeed there are many gods and many lords, yet for us there is but one God, the Father, from whom are all things and we exist for Him; and one Lord, Jesus Christ, by whom are all things, and we exist through Him.“[1]

Of Video Games and Miracles

Super MarioI suppose I grew up in the “Nintendo generation”, having graduated from Pac-Man and Donkey Kong  to spending hours squashing “goombas” to save the princess in Nintendo’s Super Mario Bros. Then there was Link, always working to save Princess Zelda. But regardless of which game I was playing or even which genre of game I played, each video game had its own consistent laws of what was possible. Mario and Luigi may be able to jump several times their own height, which is impossible in our world, but that was perfectly normal in the Mushroom Kingdom of Super Mario Brothers. And those laws had to apply equally to each player for the game to be fair. But… as any gamer knows, there are “cheat codes” – those little hidden combinations of movements, game actions, sequences of pushed buttons on the controllers, and so on, that allow a user to sidestep the rules of that game’s reality. A cheat code may let the player get more lives, become invincible, get abilities beyond what’s normal in that game’s world, access new weapons or levels, or bypass difficult levels or enemies to finish the game faster.

But what does all this have to do with miracles? Well, consider where cheat codes came from, and why they’re called cheat codes. These have historically been programming “back doors” for the game developer to test different parts of the game without having to play through the entire game at the intended rate.[1] If I’m developing the game, and I need to test game play in level 37, I don’t want to have to play through the first 36 levels that I know work well just to repeatedly test out small changes in level 37. An easy way to handle this is for me to write in a hidden jump to the higher levels, or a code for superpowers that would let me go through the tedious parts quickly. As the creator of the game, I’m outside the game, while the players are immersed in the game. I’m not limited by the rules of that game world (unless I choose to be), while the players are limited by the rules in a fair contest. With that in mind, it’s not cheating for the game creator to bypass levels or grant himself superpowers to accomplish his work. However, if a player learns of the programmer’s secret, and uses it unfairly, then it is cheating.

Now, this leads me to a few observations.
1) We are open to the possibility of miracles (i.e. bypassing or circumventing a world’s observed physical laws) in a game world.
2) We recognize that the game’s programmer isn’t violating any actual real-world constraints when he alters physics inside his game – the code he’s writing in his dimension is functioning perfectly in accordance with whatever programming language he used whether he writes a “normal” game scenario, or one with a secret invincibility switch in the game’s dimension.
3) We recognize that these “miracles” (from an in-game perspective) tend to be the work of the game’s developer as a means of accomplishing his work outside of normal game play.
4) We have an expectation that these events are not the norm, and are supposed to be used judiciously by the right person (i.e. the developer) to make the game better.
5) We recognize the right of the game developer to exercise privileges beyond our own as players.

With that in mind, I have to ask why we turn around and deny even the possibility of miracles in our physical world. Why think that it is impossible that our world had a developer – a Creator – who is not bound by our reality’s constraints? Why think that such interactions between our Creator and His creation – ones that appear miraculous from our “inside-the-game” perspective – are impossible if He’s simply not limited like we are? Why think that our Creator doesn’t have a right to alter our world’s “game” as He sees fit to make it better? When we look at the miracle of God entering the game He created at a specific point in this game’s time and space, and becoming a player like one of us, but still retaining His title of Sovereign Programmer, using His power to beat what we never could, we see a move of unfathomable love and mercy that made the game immeasurably better. Imagine playing an unwinnable level, with the deck stacked against you, and suddenly, the game creator appears in the game next to you and says, “You can’t beat this on your own, but I’ve got this – just follow me.” That’s what Jesus did when He physically appeared almost 2,000 years ago and conquered death. Will you turn away and keep playing on your own? Please don’t. There’s a better way.

Digging up Fairy Tales

Ruins in Ephesus, by Valeria RestucciaI’ve heard the Bible referred to as a collection of fairy tales, superstitions, myths, legends – fiction by whatever name you want to call it. But this got me thinking. Nobody goes looking for the ruins of Prince Charming’s castle or Captain Hook’s pirate ship. Nobody does this because they’re fairy tales. But, if someone did find the ruins of the lost city of Atlantis, or some other fairy tale/myth/legend, what would we decide? That it wasn’t just a story. Physical remains of the events of a story point to the story being actual history rather than make-believe. How then does the Bible compare? Is there actual evidence for the events recorded in it? Actually, there’s quite a bit, and the list is growing all the time. Let’s look at just a few examples.

At one time, people didn’t believe that Pontius Pilate really existed as the Bible was the earliest and most descriptive  source telling of him.[1] That was before archaeologists found the “Pilate Stone” in Caesarea Maritima in 1961. This stone’s inscription tells that “Pontius Pilate, Prefect of Judea”, had dedicated a stadium to the Emperor. This is actual physical evidence from his lifetime corroborating the Bible narrative.[2]

Skeptics since the 1800’s have doubted the authenticity of Luke’s writings in the gospel of Luke and the book of Acts in the Bible. For example, skeptics doubted Luke’s use of different official titles when describing the different encounters with tetrarchs[3], politarchs[4], asiarchs[5], proconsuls[6], and other positions in different cities. In the case of the politarchs of Thessalonica, Luke’s was the only account to use that term, and so it was seen as a historical discrepancy. Now, we have found over 32 inscriptions bearing the name “politarch”, 19 from Thessalonica, and 3 of those 19 from the first century. This has led John McRay to say that it is now “incontrovertible” that politarchs existed before and during the time of Luke’s writing.[7] In fact, 84 different historical facts in the last 16 chapters of the book of Acts have been confirmed through various archaeological finds or historical literature corroborations.[8] For the skeptic who honestly investigates the subject, it is difficult to not arrive at the same conclusion that Sir William Ramsay, the British archaeologist of the 1800’s did: “I began with a mind unfavorable to it [Acts]…. It did not lie then in my line of life to investigate the subject minutely; but more recently I found myself often brought into contact with the book of Acts as an authority for the topography, antiquities, and society of Asia Minor. It was gradually borne in upon me that in various details the narrative showed marvelous truth.”[9] His research led him from skepticism to placing Luke “among the historians of the first rank.”[10]

Looking further back, King David of Israel was believed to be a myth until the Tel Dan inscription was uncovered in 1993 that told of another king’s victory over a “son of Jehoram king of the House of David”. This was the first archaeological evidence found for King David.[11]

Christianity has always been unique in its appeal to evidence, both by Jesus and his first followers.[12] But that support has increased dramatically over the last century, and shows no signs of changing. Not only that, but the evidence that has been found consistently affirms the Biblical account. We aren’t being asked to believe in fairy tales, but rather in a reasonable account of God’s interaction with humanity as recorded through eyewitness testimony of actual historical events.
