Dr. Michael Gleghorn continues to make a compelling case for how reason can lead us, step by step, to the logical conclusion of God’s existence based on the book ‘How Reason Can Lead to God.’

Foundation of Mind

In this article we’re continuing our examination of Christian philosopher Josh Rasmussen’s book, How Reason Can Lead to God.{1} In my previous article, I introduced the book and showed how Rasmussen began constructing a “bridge of reason” that led to “an independent, self-sufficient, . . .   eternally powerful foundation of all reality.”{2}

But Rasmussen goes further, arguing that there must also be “a certain mind-like aspect” to this foundation.{3} And that’s what we’ll explore in this article. We’re going to follow Rasmussen’s lead as he takes us over the “bridge of reason.” And once we’ve taken that final step, we’ll see that it’s led us not to some cold, calculating, “mind-like” reality, but to a very “special treasure.”{4}

But to begin, why does Rasmussen think that the foundation of all reality must be “mind-like”? To answer that question, consider that one of the things the foundation has produced is you—and you have a mind. As Rasmussen notes, “you are capable of thinking, feeling, and making decisions.”{5} Indeed, if you’re awake and functioning normally, you have some awareness of what is going on “around” you—and even of what is going on “within” you. That’s because you possess a conscious (even self-conscious) mind. How is this to be explained?

According to Rasmussen there are only two live options: either minds ultimately originate from some sort of “mind-like” or “mental” reality, or else they arise solely from a physical process.{6} Is one of these options better than the other? Rasmussen thinks so, and points to “a construction problem” with the matter-to-mind option.{7} Here’s the problem. Just as a black steel pipe cannot be constructed out of emerald green toothpaste, so a self-conscious mind cannot be constructed from mindless particles. Particles just aren’t the right thing for constructing the thoughts, feelings, and purposes of a mind. In order to construct a mind, “mental materials” are needed. Hence, the foundation of all reality must be mind-like in order to account for the unique features of self-conscious human minds.{8}

But at this point, some may raise an objection. After all, if we say there’s a construction problem going from matter to minds, then wouldn’t there also be a problem in saying that an immaterial mind created the material world? The answer is “No.”

Foundation of Matter

Above, we argued that one can’t explain the thoughts and intentions of human minds by appealing only to material particles. There must rather be an ultimate mind at the foundation of all reality.

But of course, human beings also have bodies. And your body (including your brain) is an example of incredible material complexity. Not only that, but in order for you to be physically alive, the “fundamental parameters” of the universe must be delicately balanced, or “fine-tuned,” with a precision that is mind-boggling. As physicist Alan Lightman observes, “If these fundamental parameters were much different from what they are, it is not only human beings who would not exist. No life of any kind would exist.”{9}

How should we account for such complexity? Can we explain it in terms of chance?{10} That’s wildly implausible. And better explanations are available. After all, one could try to explain the words of your favorite novel by appealing to “chance.” But is that “the best explanation?”{11} Isn’t it far more likely that an intelligent mind selected and ordered the words of that story with the intention of communicating something meaningful to others? While the chance hypothesis is possible, is it really probable? If we’re interested in truth, shouldn’t we prefer the best explanation?

So what is a better explanation for the material complexity that we observe—not only in our bodies, but in the fine-tuning of the universe that allows for our existence? If the ordering of the letters and words in your favorite novel is best explained by an intelligent mind, then what about the biological complexity of human beings? Scientists have observed “that molecular biology has uncovered an analogy between DNA and language.” In short, “The genetic code functions exactly like a language code.”{12} And just as the words in a novel require an intelligent author, the genetic code requires an intelligent designer.

Hence, a foundational mind offers a good explanation not only for human minds, but for the complexity of human bodies as well. Moreover, a foundational mind also provides the best explanation for objective moral values.

Foundation of Morals

What is the best explanation for our moral experience in the world? How might we best account for our sense of right and wrong, good and evil? So far, we’ve seen two reasons for thinking that the ultimate foundation of reality is “mind-like.” First, a foundational mind best explains the existence of human minds. Second, it also offers the best explanation for the staggering material complexity of the human body and the exquisite “fine-tuning” of the universe that allows for our existence. Might a foundational mind also provide the best explanation for our moral experience? Rasmussen thinks so, and he offers potent reasons for us to think so too.{13}

Consider our sense of right and wrong. How should this be explained? Rasmussen proposes that our “moral senses are a window into a moral landscape.”{14} Just as our sense of sight helps us perceive objects in the physical world, so our moral sense helps us perceive values in the moral world. Of course, just as our sense of sight may not be perfect, such that a tree appears blurry or indistinct, so also our moral sense may not be perfect, such that a particular action may not be clearly seen as right or wrong. But in each case, even imperfect “sight” can provide some reliable information about both the material and moral landscapes.{15}

How might we best explain both the moral landscape and our experience of it? “Can the particles that comprise a material landscape, with dirt and trees, produce standards of good and bad, right and wrong?”{16} It’s hard to see how undirected particles could do such a thing. And naturally, they could have no reason to do so.

On the other hand, a foundational mind with a moral nature could account for both the moral landscape and our experience of it. As Rasmussen observes, such a being would account for moral values because of its moral nature.{17} Further, such a being would have both a reason and resources to create moral agents (like us) with the ability to perceive these values.{18} Its reason for creating such agents is that we’re valuable.{19} A mind-like foundation thus offers a better explanation for human moral experience than mindless particles ever could.

Foundation of Reason

Human minds are special for their ability to reason. This ability helps us think correctly. When we reason correctly, we can begin with certain basic truths and infer yet other truths that logically follow from these. For example, from the basic truths that “all men are mortal” and “Socrates is a man” we can logically infer the further truth that “Socrates is mortal.”

But here an interesting puzzle arises. Where does our ability to reason come from? How might we account for the origin of human reason? And one of the interesting topics tackled by Josh Rasmussen in his book, How Reason Can Lead to God, is the origin of reason itself. What’s the best explanation for this incredible ability?

If the universe sprang into being “from nothing, with no mind behind it,” then not only human minds, but even rationality itself, must ultimately come from mindless material particles.{20} But as Rasmussen observes, “If people come only from mindless particles, then reasoning comes from non-reason.”{21} But could reason really come from non-reason? Is that the most plausible explanation? Or might a better explanation be at hand?

The atheistic scientist J. B. S. Haldane once observed, “If my mental processes are determined wholly by the motions of atoms in my brain, I have no reason to suppose that my beliefs are true . . . and hence I have no reason for supposing my brain to be composed of atoms.”{22} For Haldane, if human reason arises entirely from a non-rational historical and physical process, then we have little reason to think that our beliefs are true.

Fortunately, there’s a way out of this difficulty. We can suggest that human reason comes from an ultimately rational foundation. In that case, reason comes from reason. We’ve already seen that the best way to account for minds, matter, and morals is by positing a foundational Mind as the source of all reality. And this is also the best way to account for human reason as well. As Rasmussen notes, “by anchoring reason in the nature of the foundation, we can explain how the foundation of all existence can be the foundation of minds, matter, morals . . . and reason itself.”{23}

In the next section we will follow Rasmussen “to the treasure at the end of the bridge of reason.”{24}

Perfect Foundation

In this article we’ve seen that a foundational Mind offers the best explanation for the existence of human minds and bodies, moral concepts, and even reason itself. In my previous article, we saw that this foundation is also independent, self-sufficient, and eternally powerful. Today, with some final help from the Christian philosopher Josh Rasmussen, we want to pull together the various strands of this discussion to see what unifies the various features of this foundation into a single, coherent being. What sort of being might all these features point to? According to Rasmussen, they all point to a perfect being. But why does he think so?

Rasmussen argues that a perfect being must have two essential features. First, it must have no defects, or imperfections. And second, it must have “supreme value.”{25} In other words, a perfect being cannot possibly be improved.

But why think the foundation of all reality is a perfect being? Simply put, the concept of perfection enables us to account for all the characteristics of this being that reason has revealed to us. Perfection accounts for this being’s independent, self-sufficient, and eternally powerful nature. It also accounts for how this being can be the ultimate foundation of other minds, astonishing material complexity, morality, and reason itself. As Rasmussen observes, “Perfection unifies all the attributes of the foundation” and “successfully predicts every dimension of our world.”{26}

A perfect being is thus the foundation of “every good and perfect gift” that we possess and enjoy, and must surely be described as “the greatest possible treasure.”{27} Moreover, since this being possesses “the maximal concentration of goodness, value, and power imaginable,” it can only properly be termed “God.”{28} Thus, by following the “light of reason” to the end of the “bridge of reason,” we have arrived not at meaninglessness or despair, but at “the greatest possible treasure,” the self-sufficient, eternally powerful, supremely rational, and perfectly good, Creator God.

Dr. Michael Gleghorn makes a compelling case for how reason can lead us, step by step, to the logical conclusion of God’s existence.

In 2019 the Christian philosopher Josh Rasmussen published a little book with the intriguing title, How Reason Can Lead to God: A Philosopher’s Bridge to Faith. Rasmussen earned his Ph.D. in philosophy from the University of Notre Dame and currently teaches philosophy at Azusa Pacific University.

The book, dedicated to Rasmussen’s “skeptical friends,” aims “to mark out a pathway . . . that can inspire a greater vision of the ultimate foundation of everything.”{1} Now admittedly, this is a tall order. And it leads Rasmussen into some deep philosophical waters. Still, he claims to be writing for a broad audience of truth-seekers—and he has largely managed to make the book accessible to the educated layperson. One reviewer characterized the result of Rasmussen’s effort as both an “original presentation of cutting-edge philosophy of religion, and an engaging personal invitation to reason one’s way to God.”{2}

Now I realize that you may be thinking, “Well, this doesn’t apply to me. I’m not interested in such ‘heady’ things as this.” But do you know someone who is? Perhaps a son or daughter, spouse or co-worker? If so, you’ll want to keep reading, for this may be just the sort of thing they need.
Rasmussen wrote the book for those who need to think their way carefully through the issues. The sort of person who is not content to dodge difficult questions or settle for superficial answers.

Several philosophers have praised Rasmussen’s efforts. Robert Koons, of the University of Texas at Austin, describes the book as “winsome and engaging, drawing the reader into a thrilling adventure . . . of the existence and nature of reality’s ultimate foundation.”{3} And J. P. Moreland, of Biola University, compares the study with C. S. Lewis’s Mere Christianity and claims that “Rasmussen’s argument for God is developed with such precision and care that, quite frankly, it could not be improved.”{4}

With praise like this for Rasmussen’s book, I hope you’ll agree that it’s worth our time and effort to take a deeper look at its contents. What is Rasmussen’s argument for God? How does he develop it? Why does he refer to it as a “bridge to faith”? What sort of materials does he use in constructing his “bridge”? We’ll begin our inquiry in the same place that Rasmussen does, with the deceptively simple observation that something exists.{5}

The Blob of Everything

Let’s begin by considering the book’s subtitle: A Philosopher’s Bridge to Faith. What sort of bridge is this? As you might expect, since Rasmussen is a philosopher, this is a “bridge of reason.” But it has an interesting destination, for it leads not to skepticism, but to faith.{6}

Rasmussen constructs his bridge very carefully. He wants every step in his construction project to be reasonable. In order to accomplish this, he seeks to use quality materials and first-rate tools. His
materials are statements that anyone can see are clearly true. His tools “are rules of logic.” By carefully selecting his materials, and conscientiously using his tools, he constructs “a bridge of reason that leads . . . to a special treasure.”{7}

Rasmussen begins his project with the claim that something exists. Although few will object to such a claim, some may still have doubts. After all, what if everything you think you experience is just an
illusion? Well, in that case, “the experience of your illusion exists.” Moreover, you exist. If you didn’t, you couldn’t have any doubts about reality. In order to have such doubts, you must first exist. Thus, Rasmussen’s first claim, that something exists, seems quite secure.{8}

Next, Rasmussen bundles every existing thing, of whatever sort, into a comprehensive whole, which he aptly dubs the “blob of everything.” This “blob” includes every existing thing, the totality of reality. Since every existing thing is included in the “blob of everything,” there is nothing “outside” or “beyond” it. It is everything. Hence, the blob cannot have its cause, or reason for being, in anything outside it (for, of course, there isn’t anything outside the blob of everything).{9}

Now this is strange! My car, cat, and computer were each created by causes beyond themselves. My car had a car maker. My cat had parents. But something about the “blob of everything” isn’t like this. It has what Rasmussen calls a foundational layer that doesn’t depend on anything outside itself for its existence. We’ll consider the nature of this “foundation” more carefully next.{10}

Probing the Foundation

As we just noted, there isn’t anything outside “the blob of everything.” And hence, there isn’t anything outside the blob that could cause, or explain, its existence.

What are we to make of this? Notice, first, that since the blob includes everything that exists, it includes many things that depend on other things for their existence. For example, the blob contains things like weasels, watches, and waffles and each of these things depend on other things for their existence. Baby weasels depend on mommy and daddy weasels. Watches and waffles depend on watch- and waffle-makers.

But notice: not everything in the blob can be like this. After all, if everything in the blob depended on something else for its existence, then we would have a serious problem—for the “blob of everything” does not depend on anything else for its own existence. Attempting to build such a blob using only dependent materials (that is, materials that depend on something outside themselves for their existence) would commit what Rasmussen calls a “construction error.”{11} One cannot
construct an independent, self-sufficient reality (like the “blob of everything), using only dependent parts. That would be like trying to construct a black steel pipe using nothing but toothpaste! No matter how much toothpaste you have, you will never construct a black steel pipe with such materials.{12}

So here’s the problem. The “blob of everything” includes many things with a dependent nature (like weasels, watches, and waffles). At the same time, the blob (as a whole) depends on nothing outside
itself for its existence. How is this possible? Clearly, the blob must contain some special ingredient that does not depend on anything else for its existence. Rasmussen calls this ingredient the “foundation.”{13} It has an independent, self-sufficient, necessary nature. It’s the sort of thing that must exist, no matter what.{14} It must therefore be eternal (i.e. without beginning or end) and provide “an ultimate foundation for everything else.”{15}

Eternal Power

This “foundation” that is self-sufficient doesn’t need a cause for its existence. It exists on its own. It’s the sort of thing that must exist, that cannot not exist. And for this reason, the foundation
must be eternal. That is, it must have always existed. Finally, it must also be powerful. But why?

Well, consider first that “power exists.” Rasmussen observes that there are only two ways of explaining this. The first suggests that power “came into existence from nothing.” The second says that power is eternal and has always existed. Which way is more reasonable?{16}

Well, suppose that power came into existence from nothing. The difficulty here is that something cannot come from nothing without a cause. And if there isn’t anything, then there cannot be a cause. Moreover, we must remember that “nothing” is not anything. It is the absence of anything. It thus has no potential to produce anything. It has no power or potential because it isn’t anything. Something cannot come from nothing, then, because “nothing” has no power or potential to produce anything.{17}

Thus, Rasmussen claims that reason itself drives us to suggest “a power that exists on its own, by its own nature.” In other words, since power exists, and since it can only come from something powerful, there must be an eternal power. That is, there must be a power that has always existed. This power never became powerful; it has always been powerful. Fortunately, this conclusion agrees with reason, unlike the view that power came from nothing.{18}

Rasmussen sums it up this way: “The foundational power is eternal.”{19} Now this is quite astonishing. By thinking very carefully and following the light of reason, we have arrived at a foundation of all reality that is independent, self-sufficient, necessary, and eternally powerful. But we can go even further. By considering some of the things that the foundation has produced, we can learn even more about its nature.

Implications

Let’s recap: beginning with the simple (and undeniably true) statement that something exists, we have watched Rasmussen carefully construct a bridge of reason that has led (so far) to an independent, self-sufficient, eternally powerful foundation of all reality. But Rasmussen goes still further. For if this foundation is the ultimate source of all other things, then we can learn something about the nature of the foundation by considering some of what it has produced.

For example, it is doubtless true that one of the most important things the foundation has produced is you—a human being. But what sort of thing are you? And what might this tell us about the foundation’s nature?

Rasmussen examines four aspects of human beings that reveal some important characteristics of the foundation.{20} First, human beings have minds. We are not like rocks, papers, or scissors. We are self-conscious beings, aware of our own existence. We can think, feel, make plans, and work to accomplish them. Second, we have bodies. We are not disembodied minds, souls, or spirits. There is a complex physical (and physiological) dimension to our being. Third, we are moral agents. We
experience a moral dimension to our existence. We sense that some things are good and that others are evil. We recognize that it is good to be kind to other persons and bad to harm them. Finally, we are rational agents. We can “see” or discern certain logical and mathematical truths. For example, we can “see” that two plus two equals four and that “nothing is both true and false at the same
time.”{21}

If we ultimately depend for our existence on a self-sufficient and eternal foundation, then what might this tell us about that which brought us into being? Although the details will have to wait for the next article, the various characteristics of human beings mentioned above point to “a certain mind-like aspect of the foundation.”{22} Indeed, we might even say that these characteristics reveal a foundation with mental, moral, rational—and even personal attributes!

Our goal for the next article, then, is to consider each of these characteristics in greater detail, showing how each one plausibly leads to a personal foundation of existence.
