Four Steps Backward

You're talking to someone about what you believe about God and faith in Christ and they say well that's just your opinion. That's what you believe how you respond. Stay with us Renewing Your Mind with RC Sproul's next modern philosophers tell us that our religious devotion is true. It's just a motion because of that everyone's truth is equally true were sharing our faith that we need to be able to jump over. Those are in today. Dr. RC Sproul helps us do just that.

As he continues his series defending your faith more engaged in the task of apologetics of giving and intellectual defense of the truth claims of Christianity. One of the first things that we have to grapple with in terms of our strategy of developing an intellectual defense has to do with the science of epistemology and I know that's a strange sounding word to many people, so I want to take a few moments today to explain what epistemology is and why it is so important to the whole science of apologetics. So let's put the word on the board. Epistemology EPI S TEM OLOGY epistemology is that subdivision of philosophy that focuses its attention on this basic question that so important, how do we know what we know. How can we verify or falsify claims to truth. We're doing with this all the time I say something to you and you say will how do you know and I said well I know because and I give a defense. I give a reason and I tried to substantiate that claim by appealing to some basis of knowledge and some people say why don't believe in God because God is invisible unless I can see them taste and touch and smell them her here. I'm not going to believe in it because that person says as far as I'm concerned, the only knowledge that is adequate knowledge is knowledge that can be tested through one or more of the five senses another person says wait a minute I'm from Missouri. And even if I see it, I'm not going to believe it. Unless you can demonstrate to me with the kind of certainty you get from mathematics because I know eyewitnesses to things people are often mistaken and they are deceived by what they think they say they hallucinate, and so on. So the only proof I will submit to his of the rational sort of the formal sort such as you get in mathematics at the level of 2+2 = 4, and so that first group of people are people who put the accent on the senses. The second group that I've just mentioned, put the accent on the mind and on the processes of formal recent and so when we come to the question of truth we have to say will what are the elements that are necessary for us to know that anything is true now.

There been many different approaches to this question of epistemology and particularly as it relates to apologetics. Some people argue that the only adequate apologetic is one that is rooted and grounded in historical information that is known through the five senses other say no that's a less than adequate method.

The only real way to prove the existence of God is through rational deduction and other say a pox on both your houses. The only real way you can know about God is through assuming it at the outset, as a necessary presupposition for all knowledge, and so on and so there's a difference in the house here of what mixture of these concerns are necessary in order to establish a sound defense of the Christian faith I were to come at this somewhat backwards time coming at it backwards into senses in the first way I'm coming at it backwards is as follows many years ago I was teaching a senior level course in seminary in Philadelphia Temple University. I had an elective course for my students on historic atheism and in that course as a matter of academic requirements are required that the students read the primary sources from the most formidable atheists of Western theoretical thought.

People like Jon Stewart, nil people like Karl Marx. People like Jean-Paul Sartre, Albert Camus and Walter Calphalon and others. And as we examined the primary sources of these prodigious scholars who were atheists we paid close attention to the way in which these opponents of theism established their negative case and by looking at this from the back door, I noticed a pattern emerging in the pattern that emerged was this that I found that virtually every one of these atheistic thinkers or philosophers.

At one point or another in their arguments against theism attacked one or more of four basic epistemological premises and let me explain what they are the four foundational principles of knowing that were attacked either in part or in whole by the atheists were first of all, the law of non-contradiction are sometimes called the law of contradiction, that is, in order to destroy the case for God. Some philosophers argue against the very foundational laws of reason itself, such as the law of contradiction.

The second one which was quite often attacked as we will see later, is the law of causality were sometimes called the law of cause and effect, and we will look separately at that element of epistemology. The third one that was attacked was what I call the principle of the basic reliability of sense perception. Now what were talking about when I talk about sense perception is what I said a few moments ago that our senses are five senses how we see with our eyes are here with our ears or touch with their hands or smell or so on. Those are the senses, and I right now and sing this gentleman over here in the first row and I having a perception of him through my eyes. That's a sense perception, and though I may be deceived and he may be a fig Newton of my imagination. I still have a basic trust in the basic reliability of my senses that I don't have to believe in the perfect reliability of my senses, but at least they are basically reliable and so that's the third principle in the fourth one which may sound very strange and arcane to you is what I call the analogical use of language.

Now I'm going to take the time to develop each one of these for and demonstrate why they are so crucial to any serious defense of Christian truth claims, but all I'm doing at this point is saying that by the back door by looking at the critiques offered by the most formidable opponents of Christianity and of theism.

Historically what I've said is that the pattern that emerges by atheists or from atheists is that they will negotiate. Usually one usually more than one of these four principles of knowledge and the reason I want to list them at that is that I try to encourage Christians who were seeking to defend the Christian faith to be very careful at this point in developing their own defense of Christianity that they never negotiate any one of these four principles because if they do they are giving ground that may be fatal to their case to the non-believer and I also have to add us in the side and is a parentheses that there are many Christian apologetics systems out there that in fact do negotiate one or more of these premises are principles which I think is a very serious error in their approach to apologetics now. I said that there were two backward ways in which I sought to establish these nonnegotiable principles of knowledge and one was by the inductive process of examining the historic atheists and see how they proceed. See what their assumptions are in their development of their arguments and see whether those assumptions are in fact sound the other premise that I adopted was to look and see what epistemological premises are assumed and used regularly by sacred Scripture is in the final analysis, it is the Scripture, that is our final authority. As Christians, and the Bible, though it is massively concerned about truth and about ultimate truth is not a technical textbook on epistemology the Bible doesn't give us a philosophical analysis of how rationality relates to sense perception or how sense perception relates to the analogical use of language we don't get that kind of stuff in the Bible. And yet, as we examine the Scriptures and how the Scriptures proceed, we see that there are certain assumptions or what I'm going to call here presuppositions, prior assumptions that the Bible makes in communicating its content to whomever hears it, and those assumptions or suppositions are suppositions that come from God himself that, I assume, therefore, are built to the creature as God has made the creature as a thinking creature as a sensing creature as a communicating creature and so and we see, for example, that in the Bible there is a passive assumption of the validity of the law of non-contradiction, because it is assumed the truth is not contradictory and that there is a discernible difference between obedience and disobedience between righteousness and unrighteousness between Christ and the Antichrist, and therefore we are held accountable by our maker. For if God tells us to do a that that means we are not allowed to disobey that by doing on a that is, we are not permitted to behave in a manner that contradicts what God commands or contradicts what he forbids, so that in order to be obedient to the word of God in the first instance, one has to operate within the framework of the law of non-contradiction, for without the law of non-contradiction, not a sentence in Scripture would ultimately be intelligible number to try to demonstrate that further. In our next session. But for now again were just doing a reconnaissance over the landscape here to show you the basic premises that you ought never to negotiate now what about the law of causality is that assumed in sacred Scripture will every time an appeal is made. For example in the Bible to the evidential value of a miracle. There is the assumption of the reliability of the law of causality. If Jesus says to his disciples, if you don't believe my words. Believe me, for my work's sake, or when Nicodemus came to Jesus at night and said teacher, we know that you are a teacher sent from God or you would not have been able to do the works that you do not what Nicodemus was saying is that I am connecting the dots here. I'm saying that there has to be a supernatural divine cause behind the works that you are performing or those works could not be done. And I happen to think that Nicodemus was reasoning in a sound manner. At that point but again when the Bible says look here's the miracle Christ comes out of the grave. The dead rise and we are supposed to draw conclusions from that of a divine cause for the resurrection. If we say that anything can cause anything or that anything can happen even without a cause, then the evidentiary value of the resurrection, or any of the miracles of Christ or any of the miracles of the Old Testament saints would have no value so that from page 1 in the Scripture to the end. There is this assumption of the law of causality, which again I will develop more fully in a separate lecture and show how the law of causality is so vital to Christian apologetics. Third, the basic reliability of sense perception again. Even if we grant that we can be deceived with our senses. St. Augustine, for example, use a famous example to illustrate the limits of the reliability of sense perception with his famous bent or analogy the bank or analogy was taken from those who used oars in their vessels that they would take out on the lake rowboats is at work in antiquity, and you've all been in rowboats where you put your order in the water in the middle of the noonday sun and you look down into the water where you can see the blade of the or beneath the surface of the water and from where you're sitting. It looks assures anything that the or is bent because of the refraction of light and so on and so, from your perspective. Sitting in the boat and if you know nothing about the laws of light and refraction, all that sort of thing you would come to the conclusion that you had a battle or and that's the way in which our sense perceptions can deceive us.

I look at this audience that is here today and if I put my thumb up in front of my eye, like an artist is measuring perspective in distance and so on. I close my left eye and put my thumb in front of my right eye and I see the gentleman the back row and I see that my thumbnail now conceals his whole head I could come to the conclusion that's Tom Thumb back there in the back row that his head is not as big as my thumbnail. But again, that's a matter of perspective and depth perception that we learn to adjust for all the time.

All it does is indicate the limits of sense perception. There are sounds out there that my dog can hear that I can't hear but nevertheless you know those sounds are their course you have the old argument that the philosophers make if a tree falls in the forest and no one is there to hear it doesn't make any sound or the even more modern version of that philosophical conundrum is that if a man says something in the forest and there's no woman there to hear him. Is he still wrong that this has to do with the basic reliability of sense perception we see if our senses are basically unreliable. Then we could draw no true conclusions from what we observe, or what we hear or what we handle and this of course would be the end of the physical natural sciences that we are dealing with today that rely so heavily upon sense perception in the course.

Science has long been well aware of the limits of sensation in limits of sense perception. That's why some of the greatest breakthroughs in the scientific world have come through improved equipment that extend our ability to perceive such as the microscope that makes us see things that are invisible to the naked eye, and make us aware of all kinds of things that are really there that are invisible to the naked eye, but once we place them under the microscope we see what was previously unseen.

Likewise, the telescope has radically changed our perception of the vastness of the universe because things that could not be seen by the naked eye are now clearly perceived through the use of that machine or that instrument that enhances our sense perception, but this is what the writers of the New Testament Peter for example, have already mentioned, said brother. We declare to you, not cleverly designed myths, but we declare to you what we have seen with our eyes, and what we have heard with our ears. One of the most important aspects of the importance of the resurrection in the New Testament is that it's not that on Easter morning people came to the tomb and found the tomb empty and then therefore drew an inference from an empty tomb, saying he must be risen because we can't find him because there were be other alternative explanations for a missing body and certainly the last one you would reach reasonably would be that he had been raised know the testimony of the New Testament on Christ's resurrection does not rest upon inferences drawn from an empty tomb, but rather from eyewitness testimony. We have seen him and that's why we declare these things to you as I witnesses and so the Bible appeals constantly to the basic reliability of sense perception in order to make its case about reality finally is this very arcane idea of the analogical use of language. Now that may sound a little bit technical, but is simply taken from the word analogy and we know what an analogy is. I trust that something is like something else and we point to similarities between two things in order to describe them and the reason why this is so important is that many people argue that, because God is different from us. Ultimately, that any attempt that we have to speak about him must be so much mumbo-jumbo because human language is never adequate to describe or to speak meaningfully about a transcendent being. In fact, this is been the focal point of much of the criticism against Christianity in 20th century philosophy, arguing that religious statements don't tell us anything about external reality they just tell us about ourselves. They are only emotive statements. They describe our emotions, our religious feelings but they have no counterpart in objective reality. Because language human language is inherently incapable of rising above the realm of humanity to speak meaningfully about a transcendent being and so if Christianity is going to survive these attacks that come at the basis of language we have to be able to construct some point of analogy some sense in which God is like us.

In order for there to be meaningful discourse about him. That's why for example the very beginning of the Bible.

It is asserted that God creates man in his own image and in his like that. There's an analogy there between the creator and the creature that makes discussions about him possibly will look at each one of these individually in the days to come so we can explore more fully how important each is to the defense of the Christian.

The arguments against Christianity comparable size and it seems the wind between belief and unbelief is getting brighter. We need to know how to respond to opposing views and there's no need to feel inadequate or discouraged it take some time and work to get through all of these philosophies, but you can soon have a working knowledge of them and with that in mind, let me urge you to request your resource today. It's Dr. Sproles complete series on classical apologetics. 32 messages 11 DVDs and when you requested today will also include a bonus disc with a study guide for the series. Again, the title of the series is defending your faith.

You can go to Renewing Your Mind.org to make your request or you can call us with your gift at 800-435-4343 RC believed it was important to explain theology simply without being simplistic and in keeping with that approach, I'd like to introduce you to a podcast from leader ministries called simply put, each Tuesday my colleague Barry Cooper sheds light on the different biblical or theological term. For example, propitiation one is that when the Bible speaks of propitiation. It is talking about the appeasement of gold's rightful anger at sin. Now this can make people bristle at the local was mostly loving, why would he be angry at anyone. Sin but is anger really the opposite of love less, just a sample of the podcast of Barry also provides helpful illustrations to apply to your life.

It's a short easy lesson each episode about five minutes so check it out is called simply put, subscribe on iTunes, Google play, or by visiting simply put podcast.com will before we go today. Here's a preview of what will hear tomorrow is RC continues his series on classical apologetics. I find that the majority of students who walk in the door in the seminary today have already been convinced by the secular that truths can be irrational and that the Bible can be contradictory and still be the word of God and it's an astonishing thing. We hope you'll join us Wednesday or Renewing Your Mind
