Logic, Thought and Steven Hawking

Hawking and Mlodinow’s book The Grand Design  is fascinating. It is a look into theoretical physics that I appreciate. One comment on page 180 seems to be getting all of the press: “Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist. It is not necessary to envoke God to light the blue touch paper and set the universe going.” This problematic statement is seen as a major victory for atheism. But, I note the comment on page 181: “…perhaps the true miracle is that abstract considerations of logic lead to a unique theory that predicts and describes [the universe].” Note the reference to logic.  The abstract laws of logic shape the way all of us think. Take one for instance: the law of non-contradiction. It says that something can not be both A and Non-A at the same time, in the same relationship, and in the same sense. This law cannot be denied. To deny it is to affirm it. If you say, “The law of non-contra...

Am I a Christian just because I was raised that way?

I have recently shared much of my experience growing up in an evangelical church . I had many experiences, both good and bad, but by and large the experience was positive. I was raised Christian, and I am Christian today. Does this mean I am biased? Yes, but that does not mean I am wrong . The strength or weakness of an argument should be evaluated independent of the circumstances of the person giving the argument. Besides, we are all biased in some way or another, if we are honest with ourselves. The accusation that “you believe only because of your circumstances” goes both ways. After all, we all have faced and are facing circumstances that shape our views. I am an intelligent adult. I am not now a “product of my raising.” I am a Christian by choice, and my religion is my own. I like the way Cornelius Van Till addresses concerns on bias here . I urge you to review the arguments I give critically on their own merits. Let them stand for themselves.

God Is, Part 3 - Thinking about Thinking

God establishes reason, and without Him, we have no reason to be reasonable. We reason by the laws of logic combined with facts we observe. For example, the Law of Non-contradiction, that A cannot be both A and non-A at the same time and in the same relationship. These abstract, conceptual principles must be accounted for if any discussion on any topic is to take place. Only God can account for these laws. His thinking upholds ours. If the laws of logic are based on human thinking, then we have to realize that people are different and the laws may differ from person to person. They are no longer absolute. Some particular examples follow. If the laws of logic are just social conventions, then they are not absolute, and they can be ignored at will. My social network is, after all, different from yours. How do we avoid the conclusion that all of our thinking is not the result of mere instinctive reactions to our environment? Since our environments are all different, we would all reach dif...

R. C. Sproul Comments on Anthony Flew’s Book

Reformation 21 has published a review by R. C. Sproul on Anthony Flew’s new book: There Is a God: How the World's Most Notorious Atheist Changed His Mind. (HarperOne: New York, 2007). Here’s an excerpt from Sproul’s review: …There are those who argue that the laws of nature are merely convenient forms that human investigators impose on nature, that nature's facts are brute facts and mute facts, and have no inherent design. Design is something that is merely projected upon nature from the thinking of the scientist. In this case, Flew argues that the atheists accept the laws of nature simply by faith, and pursues the point that these laws are not something that are the result of cultural creation, but rather the discovery of something that exists within nature itself. Newton did not invent the law of gravity or impose a principle of gravity on the natural world; rather, he discovered it as an external reality. Now, the very presence of laws in nature indicates that nature ...

Can we learn everything from science?

I am a Master’s degreed industrial engineer. I make my living by using a problem-solving method called Six Sigma . In short, this is a detailed problem solving methodology based on statistical methods. I spend my days looking at manufacturing and service processes and analyzing their performance with 2-sample t-tests, ANOVA tables, Chi-squared tables, Factoral Experiments, and many other scientific methods of designed experimentation. I have grown to see many things in life through the window of hypothesis testing , the most often used scientific research method. I have a supreme respect for the scientific method, but there are things that science cannot prove. It must assume certain foundational principles. Science assumes an external world that is orderly. By orderly, I mean a world that is organized according to basis principles. This assumption cannot be proven by science because the only way that science can explain order is to find more order. The law or theory is explained by an...

Reasonable Faith

“Christianity is a rational religion. If it’s not rational, it’s not Christian.” – John Wesley “That knowledge [knowledge of God] is at least rational knowledge.” – Francis Schaefer , commenting on John 17:3 According to one online service , something is rational when it is “consistent with or based on or using reason.” Examples of the word’s use are: "rational behavior"; "a process of rational inference"; "rational thought." Christianity is the most reasonable of religions. In fact, I would call it the only reasonable position to take. We have nothing to fear from the facts. Unbelievers have good questions, but I find that those questions are rarely, if ever, new questions. The answers have been around for a long time. Many of them were answered by the Apostle Paul , and he used answers given him by study and meditation on Old Testament texts. There is another part of this. A part that does not reflect well on American Christianity. Another definition of ...

Some Quotes Deserve a Post

An interesting article by Jonathan Barlow over at CRTA concludes as follows: I would do well at this point to break away and leave Dawkins in the morass of his purely contingent universe in which not even logic, science, and morality make any sense. For all of his huff and puff against faith, Dawkins lives in a drafty house of pure scientism that he has sealed up with faith -- faith in logic, of whose foundations he can give no account, faith in induction, upon which he builds science, and faith in the evolving human brain and the evolving human society to more often produce Martin Luther Kings than John Wayne Gacys. Strong words. Other links on the site back up these claims.

Nine Reasons Why Christianity is The Only True Religion, Part 4: God Makes Possible Logic, Rational Thought, and Science

Logic and Thought Have you ever spent an afternoon thinking about thinking? Most people I know would quickly answer with a resounding “no.” Some would throw in an expletive. I am afraid I am the type of person who thinks about thinking, and I am grateful to know I am not alone . One aspect of thinking is our ability to determine the internal consistency of ideas. We need to be able to know whether our thinking method itself is accurate. This is the realm of formal logic. Formal logic has always fascinated me. The laws of logic shape the way we think. They are an open window to the Christian God’s world. Take one for instance: the law of non-contradiction. It says that something can not be both A and Non-A at the same time, in the same relationship, and in the same sense. This law cannot be denied. To deny it is to affirm it. If you say, “The law of non-contradiction does not apply,” you could mean, “The law of non-contradiction does indeed apply.” The meanings would be the s...

Intuition

I found an interesting article by Greg Koukl over at Stand to Reason . It’s an interesting discussion of intuition from a philosophical perspective. I’m a big fan of intuition, and I make many decisions based on it. Here’s an excerpt: I'm convinced that many of the things essential to a Christian world view are things all human beings already believe without being told: the idea that human beings are special, valuable, made in the image of God and have transcendent value; that there's purpose in life; that man is not only valuable, but twisted, sinful, and guilty and deserves to be punished; that God is real and has made an orderly universe and designed it for a purpose … Some of these things I mentioned are known through the faculty of intuition. When I say "intuition," I mean something very particular … I don't mean a hunch about something. I mean a way of knowing which is immediate and direct. It's knowledge you start with, knowledge that's already ...

How do we know …

How do we know what we know? How do we know what is true? How do we evaluate one idea against another? How do we interpret the information our senses provide us? What do we see? Hear? Touch? Smell? Taste? These questions fascinate me. I first began to ask questions like this as I studied Human Factors Engineering (HFE) in graduate school. HFE is a branch of engineering that studies how a human being interacts with their environment, usually with respect to how we obtain information and how we perform work. We looked at basic types of mistakes that people make, the way we obtain information from our senses, the way we process that information, the way we decide to act, and the way we activate machine controls to act on that processed information. The field includes ergonomics , but it included much more than that. One of the things we learned right off the bat was that the way we interact with our environment is a process. Think of a black box with arrows going into the lef...

The Most Reasonable Faith

I heard some testimonies the other day that really stressed me out. Several people shared that Christianity implies the need for a “leap of faith,” or that “God’s existence cannot be proved because then faith would not be faith.” These ideas will not strengthen faith when Christians are confronted by worldly philosophy. God's existence is as plain as the nose on our faces ( Romans 1:18-19 ). Many, from The Apostle Paul to St. Augustine to St. Thomas Aquinas to John Gerstner to Greg Bahnsen , have proven the faith beyond doubt. The problem is not the lack of evidence, but the suppression of it. The unbeliever does not want to submit to God, so he or she refuses to acknowledge the truth that is plain ( Romans 1:21-23 ). There is no need to fall back on a position that says God's existence is to be taken on faith, as if faith is something that goes beyond reason. The Christian faith is the wisdom of God that makes foolish the wisdom of this world ( 1 Corinthians 1:18-25 ). The C...

God establishes reason, and without Him, we do not have reasons for reasons. We reason by the laws of logic combined with facts we observe. For example, the Law of Non-contradiction, that A cannot be both A and non-A at the same time and in the same relationship. These abstract, conceptual principles must be accounted for if any discussion on any topic is to take place. Only the Christian God can account for these laws. His thinking upholds ours.

The Trinity is Logical

At the request of a Muslim I have been having online exchanges with, I wrote the following bit about the trinity. I have reprinted it here, along with links, quotes and augmentations. You had requested an explanation of the Christian doctrine of the Trinity. Pardon my delayed response due to my father-in-law’s illness. To begin, God is one being. Christians do not worship three Gods, but one (Deuteronomy 6:45; Isaiah 45:5-6 and 21-22; Isaiah 44:6-8). We do not worship more than one God as Surah 5:73 states. That would be “tritheism,” which we condemn. Baptists like myself do not see Jesus, Mary, and God as the trinity as is suggested by Surah 5:116-117. This elevates a human, Mary, into the God-head, and we would see that as “adoptionism,” which we condemn. We would also condemn as adoptionism any thinking that says Jesus ever became God. Jesus was not created. He did not become God at some time. He has eternally existed. God exists as three persons and as one being. This is logical...

The Linear Argument Showing the Bible to be God’s Word

Time after time an opponent of Christianity accuses us of circular reasoning . The statement we are accused of making goes like this: The Bible claims to be God’s Word so it is God’s Word. That is “begging the question,” where the conclusion is true only if the premise is true. However, the actual argument put forth by Christians is linear and logical. In bullet point form, it goes like this: · The Bible is good history ( The New Evidence that Demands a Verdict by Josh McDowell). · We can trust what the Bible says about Jesus because it is based on eyewitness testimony (Luke 1:1-4, 2 Peter 1:16). These eyewitnesses were willing to die for their faith. · Jesus claimed to be God. He said, “I and the Father are one” (John 10:30). Thomas said, “My Lord and my God,” and Jesus did not correct him (John 20:26-31). · Jesus worked miracles and proved Himself to be God (John 14: 9-11). · Jesus affirmed the truth of God’s Word. He said, “Man shall not l...

Richard Dawkins – 1

Richard Dawkins’ book The God Delusion (New York: Houghton Mifflin Company, 2006) evokes strong feelings. Most of the arguments presented are not cogent, and the next post or two will address some of them. Not everything will be addressed. Some of the statements he makes about probabilistic arguments seem intelligent. Some do not justify a response. The case presented will outline a strong confirmation of the basic tenants of Christianity. Dawkins quickly dismisses all of the classical arguments for God’s existence without reason. His issue is the infinite regress. This argument, called the cosmological argument because it is an argument from the existence of the cosmos, is more fully stated in the post Logic and God 3 . There are other forms of this argument ( what Norman Geisler calls the horizontal form for example ), but those are better stated elsewhere. In brief, the argument proceeds backwards through the series of causes that arrive at us. We cannot expect that an infinite reg...

Logic and God 3

For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who by their unrighteousness suppress the truth. For what can be known about God is plain to them, because God has shown it to them. For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse. – Romans 1:18-20, ESV Richard Dawkin’s book The God Delusion is an interesting set of polemics. If it were possible to win an argument based on insults and innuendo, this book would have ended all positive discussion of belief in God. Future posts will contain some of the more interesting quotes. Once again someone states that there is no positive argument which proves God’s existence. To answer with one line of thinking out of several, God is eternal. He has no beginning and no end. This is foundational for a very reasonable argument for His existence...

Logic and God, Part 2

Many contemporary believers do not feel the need to have a rational basis for their Christian faith. For example, Robert Webber’s comment in Ancient-Future Faith (Grand Rapids, Michigan: Baker Books, 1999, p. 185): …Christianity is not provable outside itself through the scientific method. One must come to the Christian faith believing that it is true and embrace it as such without any dependence on data outside the faith. Christianity requires trust, a believing embrace, a willingness to step inside its story apart from any dependence on historical, scientific, or rational persuasion. So, according to Webber, Christianity requires a blind leap of faith for entrance. I always think of the Indiana Jones movie where he must jump across a chasm not knowing whether there is anything to catch him as he falls. When he jumps, he falls onto a bridge that was hidden from view by exquisite camouflage. Is that kind of leap the requirement, or are there reasons to believe what we believe? Let’s l...

Robert Webber 1

Robert Webber’s comments in Listening to the Beliefs of the Emergent Church lead me to take a book by him off my shelf which had been there for a few years: Ancient-Future Faith (Grand Rapids, Michigan: Baker Books, 1999). I looked back through my underlinings and dog-ears to find some quotes. Several came to mind. One is on page 177: The debate of the fourteenth and fifteenth centuries paved the way for the Reformers who chose the doctrine of sola scriptura. The Reformers pulled Scripture away from the church, separated it from tradition, set it over against popes and councils, and made it stand on its own. I question whether the Reformers pulled the Bible away from church tradition. It is more likely that they returned to the original interpretations of Scriptural authority held by the Early Church Fathers. Keith Mathison in his excellent book The Shape of Sola Scriptura (Moscow, Indiana: Canon Press, 2001) shows that the interpretation of the early church on Scriptural auth...

Listening to the Emergent Church

I am just about to finish the book Listening to the Beliefs of Emerging Churches , Robert Webber, ed. It’s an interesting read, and a helpful introduction to the theological issues involved. (I expect several upcoming blogs entries on material found in this book.) One of the essays included raises some issues with me: “The Emerging Church and Embodied Theology,” by Doug Pagitt . Pagitt states on p. 137: I hold that a reading of history ought to instruct us to create ways of thought that are useful but temporary. Complex understandings meant for all people, in all places, for all times, are simply not possible. Language, situation, specific issues, and people’s own preferences and insecurity all are involved in any belief system. There is no way to make a statement of substantive belief without these kinds of issues at play. So one must make adjustments, even if they are slight, in order to remain faithful. Let’s focus on “Complex understandings meant for all people, in all places, for ...

Or They Will Kill Us

The recent shooting at Virginia Tech. brought to mind a passage from a book I read a few years back. Here it is at length: Early in the twentieth century, Baptist evangelists preached through rural Mississippi and Alabama with such effectiveness that moonshiners could no longer sell their whiskey: All their customers were getting converted! In desperation, the whiskey sellers hired two men to murder one of the leading Baptist preachers. Pistols in their hands, the assassins waited in the dark outside a country church where their target was preaching. The evangelist spoke with burning intensity about heaven and hell, his voice ringing out into the night. When everyone had gone, he turned out the church lights and stepped outside. The killers approached him, pistols in hand. But instead of shooting the evangelist, they handed him their guns. “We came here to kill you, but we couldn’t,” they said. “We heard your preaching and we believed it. We’re now on the same side.” That story was tol...
