We've heard that every effect has to have a cause. But if we apply that assertion to the beginning of all things, it leads to the question, did God have a cause?
Stay with us. Renewing Your Mind is next. Or to put it another way, when did God begin? It's one of those questions that makes your head hurt, isn't it? But it is an important question to answer if we're going to give a reasoned defense of the Christian faith. This is a lesson that requires us to put on our thinking caps, but we are in the hands of a more than capable teacher, Dr. R.C.
Sproul. Today we're going to continue our study of apologetics, and what we're in the middle of at this point is examining four principles of knowledge that are crucial for any sound defense of Christianity, principles that are constantly under attack by those who deny the existence of God. And so far we've isolated four of those what I call non-negotiable principles that are necessary to human knowledge, number one, and also principles that are assumed by all people and also assumed in the pages of sacred Scripture. And the four that we've isolated, I remind you, are the necessity of the law of non-contradiction, second the law of causality, third the basic reliability of sense perception, and fourth the analogical use of language. And already we've looked at the law of non-contradiction, and you recall I said that people certainly can deny the law of non-contradiction and its validity, and people do that, and they do it frequently. But what I pointed out was that all denials of the law of non-contradiction are forced and temporary because it's impossible to live, to even survive for 24 hours, if you consistently deny the validity of the law of non-contradiction. You can't drive your car to an intersection, see a Big Mac truck coming down the highway and say to yourself, self, there's a truck there and not there at the same time and in the same relationship.
There, though you may with your lips deny the validity of the law of contradiction, you apply pressure on the brake because you know you can't survive in that contradictory world. Well, let's move on now today to the second principle, which is the principle of causality, and the principle of causality is one that was used in a formidable way throughout the history of Western theoretical thought to argue for the existence of God by reasoning from the appearance of this world back to an adequate or sufficient cause that would explain this world or this universe. And so thinkers in the Middle Ages and down even beyond that reasoned from a causal base back to God as the first cause. In fact, we go all the way back to Aristotle, who argued that God is the first cause because things require a cause. Now, however, since the Enlightenment, since the 18th century, considerable skepticism has emerged against the law of cause and effect or the law of causality.
If, for example, you've read Bertram Russell's little booklet, Why I Am Not a Christian, he gives his own personal testimony of his pilgrimage with respect to theism. He said, as a boy growing up, he was deeply impressed by the argument for the existence of God that was based upon the need for a first cause, based upon the law of causality. And so as a young boy, he embraced the idea of the existence of God until he read an essay written by the philosopher John Stuart Mill, who raised this basic objection against causal thinking. Mill said it this way, if everything requires a cause, then manifestly God would require a cause, and whoever caused God would require a cause, so that you can't reason back to God on the basis of the principle that everything must have a cause. Now, when Bertram Russell read that essay at age 17, he said it was an epiphany for him, and he realized that the law of cause and effect would not lead you to the conclusion of a first cause, but would lead you on an endless regress that would get you in the final analysis not to God, but nowhere. And so he, therefore, denied the utility of arguing for the existence of God on the basis of the law of cause and effect. Now, let me just respond to that very briefly and very simply, that here's one of those classic examples where Homer nods. John Stuart Mill was unarguably a brilliant philosopher, very well trained in logic and skilled in analytical thought and cognition, and he made a fundamental foundational error in his thinking with respect to causality.
The primary error was an error in definition. He assumed that the definition of the law of causality is simply, everything must have a cause. Now, if that indeed were the classical law of causality, then his criticism of causal reasoning back to a first cause would be valid.
Let me put it in simple terms. I heard the story of two little boys that were having a discussion, and the first little boy said to the second little boy, where did the trees come from? And his friend said, God made the trees. And then he said, well, where did the flowers come from? And his friend said, God made the flowers.
And his friend said, well, where did you come from? And he said, God made me. And then his buddy said, well, who made God? And his partner said, God made himself. Now, I remember also my mother telling me that when I was about three years old, I asked our minister who made God. And my minister was super impressed by that and told my mother, you know, you have a child prodigy on your hands here, and this boy is going to grow up to be a theologian or a philosopher or something like that. And my mother was fond of telling me that when I was pursuing a career in theology. She said, I always knew you were going to do that because the minister told us that when you were three years old. And I said, Mom, let me tell you something.
She said, what? I said, every three-year-old kid asks that question. Where does God come from? I mean, that's as normal a question as any child can ever ask.
It doesn't show any particular insight on my part at three years old or at 10 years old. I said, however, we somehow stop and say, boy, that little kid is profound when he says, who made God? Who made himself?
No, no, no, no, no. Even God can't make Himself. And the point is, we don't have to have an antecedent cause for God. God, as Aristotle rightly understood, is an uncaused cause. And you don't have to provide a cause for an eternal being, as we will see in the course of this study.
Just now, by way of shorthand, let me just say that the error is in the definition. The law of causality has never said that everything has to have a cause. Rather, the law of causality stated properly says every effect must have an antecedent cause. Every effect must have an antecedent cause. Now, had John Stuart Mill been working with that definition of causality, he would never have gotten himself into the mess he did and never would have led Burch and Russell astray into that morass of confusion, which, by the way, that principle that Burch and Russell, as brilliant as he was, adopted at age 17, he maintained till the day he died.
That error continued in his thinking. Because the definition of the law of causality, again, is not that everything must have an effect, because if everything had to have a cause, God indeed would have to have a cause. But the law simply says every effect must have a cause. And if we could find something that is not an effect, that is something that has the power of being within itself and is from eternity, obviously that being would not be an effect. And when we define the character of God, we say that God is a self-existing, eternal being who is independent, underived, not contingent, but He's eternal. He is not caused because He is not an effect.
Only things that are made are effects. Now, if we look at this definition, we see, and I get just a little bit technical here, that this definition, every effect must have a cause, is a statement that we say is formally true. Not formally, but formally, you know, that is to say it is a formal truth. Now, what is a formal truth? A formal truth is a truth, I'm trying to make this easier and I'm going to make it more abstract. A formal truth is a truth that is analytically true.
Whoops, I'm trying to simplify and I'm making it worse, right? If it's formally true, it's analytically true. What that means is that it's true by definition, that if you analyze this statement, every effect must have a cause.
Just by analyzing the words and their relationship in the statement, you will see that the statement not only is true, but by definition has to be true. An analytical statement would be one like this, a bachelor is an unmarried man. Now, in an analytical statement like that, a bachelor is an unmarried man. You have the subject, which is the word bachelor, and then you say something about the bachelor to describe him. You predicate something about the bachelor, and what you say is the bachelor is an unmarried man.
But what do you find out about the bachelor in the phrase unmarried man that you didn't already know with the word bachelor? See, in an analytical statement, there's no new information given in the predicate from what's already there in the subject. If I tell you, let me say, a triangle has three sides. Is that true or not? Of course it's true.
It has to be true because a triangle by definition has three sides. Just like a bachelor by definition is an unmarried man. Now, not all unmarried men are bachelors. Some are widowers, right?
But all bachelors are unmarried men. So, what we say that something is formally true or analytically true, another way of saying is it's logically true. It's true by definition.
Now, again, let's look more carefully at the definition. If we say every effect, and just stop right there, and we introduce the word effect. What is an effect? How would you define an effect? What is an effect?
Something that happened or something that will happen, that's true, but something that has been made, something that has been produced, right? Or to use the language, something that has been caused. See, an effect by definition is something that has been caused by something else. Now, what is a cause? What is a cause? What does a cause do?
It brings some kind of result, and what do we call that result? An effect, that's right. You can't have a cause that doesn't cause anything. What a cause causes is an effect. So, you can't have a cause without an effect, and anything that is identified as an effect, by definition, must have a cause. So that in a very real sense, this statement, every effect must have a cause, is just simply a mental extension of the law of non-contradiction. Because something cannot be an effect and not be an effect at the same time in the same relationship. Something cannot be a cause.
You can't have a cause without an effect, and you can't have an effect without a cause, because otherwise you have a contradiction. Now, the most primary answer we give to reality, if I say, why is this carpet here in this room? The simplest answer I can say is because.
That's not going to satisfy you. You're going to want to push me a little bit further, and you're going to say, because why? Well, I'm going to say, well, because the director of this studio wanted to construct a set that would have the look of a study or a den, and so he went out and got this old carpeting, and he put it on the floor here as part of the set. So now I'm giving you more of the complex reasons behind the presence of this carpet that is now underneath my feet.
Okay? Now, my director didn't cause the carpet. If I said, what caused the carpet, then I would have to go back to the manufacturer and all of that sort of thing. But we understand the use of that language at a very elementary way. One of the first things a parent learns how to say to a child when the child asks a question is, because. That's the answer. In other words, we're saying, that flower has a cause.
That tree has a cause. Something has produced it. Because we also understand that something cannot come out of nothing.
Now, again, I'm going to ask you to put your thinking caps on because I'm going to do some close work with your minds here. When I say this is a formal principle, we're saying that it doesn't teach us anything directly about reality. It doesn't tell us that there are causes out there in the real world. It doesn't tell us that there are effects out there in the real world. Maybe everything in the world is eternal and uncaused.
I don't believe that that's the case. But I'm saying, hypothetically, we're sitting here in this room, and I'm saying there's all kinds of things outside of this room. There are cars and trucks and planes and bees and trees and all the rest.
And I can say this to you for sure. That if any or all of those things that I've just listed, trucks and trees and cars and all of that, are effects, then we know for sure that they have what? Causes. Now, maybe they are not effects, but the principle is, the logical principle is, if something is an effect, it must have what? It must have a cause.
So that if you can establish that something is indeed an effect, then you have established that it must have some kind of antecedent cause. Several years ago, when we produced our book on classical apologetics, and it was reviewed by scholars around about the country, one scholar who was a philosopher made one criticism, one substantive criticism of the argument set forth in that book. And he was criticizing me, and he said, I'll never forget it, he said, the problem with Sproul. Now, I'm not going to give you people the opportunity to fill in the blank there.
What he said was, he was referring just to this book, not to my whole life, but he was saying that the problem with Sproul in this book is that Sproul will not allow for an uncaused effect. That was his criticism. Now, my basic rule of thumb is, is that if I receive one of my books criticized in a review, I never bother to get engaged in a debate or discussion with the reviewer.
I just, you know, that's their job is to review it, and whatever they say, that's fine. I'm not going to argue with them. But this one I couldn't pass up. So, I wrote to the philosopher a nice letter, and I said, you indicated in your review that the one problem that you had with my book was that I wouldn't allow for an uncaused effect. And I said, mea culpa, you're right, I won't allow for an uncaused effect.
But I thought that my obstinate refusal to not allow for uncaused effects was a virtue, not a vice. Now, I would be happy to allow for an uncaused effect if you would take the trouble to write to me one example anywhere in the universe of an uncaused effect. And, of course, I'm still waiting for his response because I know and he knows upon a moment's reflection that you can't possibly have an uncaused effect because an effect by definition is something that has an antecedent cause. But that's only one of the reasons why an avalanche of doubt has been leveled against traditional causal thinking. The other reason which we will explore in our next session is the critical analysis of causality that was launched by the British empirical philosopher David Hume. David Hume's watershed critique of causality has led many thinkers after him to believe that David Hume demolished causality altogether. And in our next session, I'm going to examine that analysis of Hume and the assumption that goes with it that he, in his critical fashion, demolished the whole arguments and the whole law of causality, which I hope prove to you that he did not at all.
But again, let me just recapitulate that denials of the law of causality are frequently found in those who argue against classical theism, who want to avoid the enormous power of causal thought that drives people to give a sufficient cause for effects that we recognize to be effects. That's Dr. R.C. Sproul with a message from his series Defending Your Faith. You're listening to Renewing Your Mind on this Thursday.
I'm Lee Webb, and thank you for being with us today. We worked through some heavy material today, concepts that may require a second or third listen. We'd be happy to send you the entire series for your gift of any amount. There are 32 lessons on 11 DVDs, and if you've defended Christianity to a skeptic, you know how important it is to be prepared, and that's why we're offering this entire series to you.
There are 32 lessons on 11 DVDs, and for your gift of any amount, we'll be glad to send it your way. There are a couple of ways you can reach us by phone at 800-435-4343. You can also find us online at renewingyourmind.org. Well, Dr. John Tweedale is with us here in the studio today. He is a professor of theology and academic dean at Reformation Bible College. Interesting to note, as John told us yesterday, he actually set in on this series when Dr. Sproul taught it some years ago. John, if you will, assess for us how well-prepared young people are to defend the faith. So often, talking to college students in churches where I have served or spoken, many of them are overwhelmed with questions, and they need robust answers to handle really complicated problems that they are facing in their own lives and in the culture around them. So I think there is need for greater education and greater teaching and more training, and that's why we exist here at Ligonier. It's why we exist at RBC is that we want to flood the world with good biblical teaching. And it's why we're offering this series to you by Dr. Sproul.
It's Defending Your Faith. For your donation of any amount, we'll send it to you when you contact us at renewingyourmind.org or when you call us at 800-435-4343. And if you'd like to know more about Reformation Bible College where Dr. Tweedale serves, you can check out their website at reformationbiblecollege.org. Well, you heard Dr. Tweedale say that we want to flood the world with good biblical teaching. That means translating our resources into multiple languages. I hope you'll join us tomorrow as we tell you about our latest outreach to the Spanish-speaking world, an area that by and large the Reformation did not reach. So please make plans to join us back here Friday for Renewing Your Mind with R.C. Sproul. .
