William Lane Craig asks: are there objective truths about God?

A conflict of worldviews

In a lecture entitled “Are there Objective Truths About God?”, philosopher William Lane Craig discusses the problem that Christians face when they make truth claims about God to non-Christians. We think that there are objective truths about God – that there are some propositions that describe the way God really is, in reality. We think that people who don’t believe in those objective are factually wrong, in the same way that someone who thinks that Toronto is the capital of Canada is factually wrong.

But some people want to say that every statement about God is true “for each person” – so that conflicting claims about God are fine and no one is wrong. This could only be the case if everyone is just describing their own preferences, though – if they are making subjective claims about themselves, and not objective claims about God. Unfortunately, Christianity claims to be true for everyone – (e.g. – God is three persons and one being), so that Christians are committed to defending the idea that there are objective truths about God.

So what questions does Bill answer in the lecture?

What is a self-refuting statement?

The main concept in the lecture is self-refutation. A self-refuting sentence is a sentence that, if true, makes itself false or meaningless. For example, suppose someone said to you: “there are no sentences longer than 5 words” then that would be self-refuting since it falsifies itself. Bill argues that objections to the idea that there are objective truths about God are all self-refuting.

What is truth?

Craig holds that “truth” is a property of a proposition such that a proposition is true if it corresponds to the external world. For example, if I claim that there is a crocodile in your closet and we find a crocodile in your closet, then my statement was true. If there is no crocodile in your closet then my statement was false. The real objective world out there is what makes propositional claims true or false – these are not claims about an individual’s preferences, they are claims about the world. Bill is concerned with truth claims about God that are objective – whether there are propositions about God that are true regardless of what anyone thinks.

Objections to objective truth

Bill discusses 3 objections to the idea that there are objective truths about God. Each objection seeks to make religion subjective, (true for each person, like food preferences or clothing fashion).

Objection #1:The Challenge of Verificationism

The first challenge is that religious claims cannot be verified using the 5 senses, and therefore religious statements are objectively meaningless.

Consider the statement “Only propositions that can be verified with the 5 senses are meaningful”. That statement cannot be verified with the 5 senses. If the statement is true, it makes itself meaningless. It’s self-refuting.

Objection #2: The Challenge of Mystical Anti-Realism

The second challenge is that religious claims, and claims about God, are neither true nor false.

Consider the statement “Propositions about God cannot be true or false”. Craig asks – why should we accept that? Any reason given would have to assert something about God that is true or false, and those reasons would contradict the original statement. For example, “God is too great to be grasped by human categories of thought” is a proposition about God that the speaker thinks is true, which contradicts the original assertion.

Objection #3: The Challenge of Radical Pluralism

The third challenge is that each person invents an entire reality of their own, and that there is no mind-independent objective world shared by individuals.

Consider the statement “There is no objective reality shared by all individuals”. That statement is a statement that applies to all individuals, regardless of what they think.  It’s self-refuting.

Conclusion

Craig ends the lecture by arguing that it is OK for Christians to think that other people’s views are false. It does not follow that just because someone thinks other people’s views are wrong that they am going to mistreat other people. In fact, in Christianity it is objectively true that it is good for Christians to love their enemies. It is objectively true that all human beings have value, because human beings are made by God. So even if Christians disagree with others, they still treat them well, because they think that there are moral truths that they have to conform to.

My thoughts

Sometimes, non-Christians think that it is dangerous to hold beliefs too strongly. But I think what really matters is the content of the belief – some beliefs are false and some are true – you want to believe the true beliefs as strongly as you can, as long as the evidence warrants it. In Christianity, I am absolutely obligated to treat people with whom I disagree with respect and gentleness (1 Pet 3:15-16). The more convinced I am about that belief, the better my opponents will be treated. A stronger belief in Christianity means more tolerance for those who disagree.

Why do non-Christians get so offended when Christians claim to be right about there being only one way to be rightly related to God? Well, for many it’s because their worldview is a personal preference, and they feel uncomfortable having to defend it rationally and evidentially. For most people, religion is just their cultural preference – like cooking style, or favorite sport, or clothing style. That’s why they respond to your truth claims with name-calling like “you’re intolerant” and “you’re judgmental” and “you’re arrogant”. These are just shorthand ways of saying, “I’m offended that you’ve thought things through more than I have, and now I look dumb”. My family is from a non-Christian culture, so I have to talk to my relatives about this all the time. They feel judged, but it’s not my fault that they haven’t done any homework to prove out their beliefs.

I got this “you’re mean” reaction a lot from people who are raised to think that their religion is a racial, national or cultural identity. They think that if you tell them they are wrong  on matters of fact that somehow this amounts to some sort of racism or prejudice. You make factual claims, and they hear discrimination. But that’s not how Christians think of religion – we only care if it’s true or not – just like we care whether the claims of history or science are true or not. We not trying to be mean, any more than it’s mean to say things like “water boils at 100 C”. That’s just the way it is, and we’re more than happy to discuss the reasons why we think that, and to look at your reasons to see why you don’t think that.

 

Self-refuting statements defined and some common examples

A conflict of worldviews
A conflict of worldviews

A fine article by Aaron, who writes at Apologetics Junkie.

Excerpt:

A self-defeating (or self-refuting) statement is one that fails to meet its own standard. In other words, it is a statement that cannot live up to its own criteria. Imagine if I were to say,

I cannot speak a word in English.

You intuitively see a problem here. I told you in English that I cannot speak a word in English. This statement is self-refuting. It does not meet its own standard or criteria. It self-destructs.

The important thing to remember with self-defeating statements is that they are necessarily false. In other words, there is no possible way for them to be true. This is because they violate a very fundamental law of logic, the law of non-contradiction. This law states that A and non-A cannot both be true at the same time and in the same sense. For example, it is not possible for God to exist and not exist at the same time and in the same sense. This would violate the law of non-contradiction. So if I were to say, “God told me He doesn’t exist” you would see intuitively the obvious self-refuting nature of this statement.

Aaron goes on to explain how to deal with self-refuting statements in the article.

Here are 20 examples of self-refutation, just to encourage you to click through and read it:

1. There is no truth.

2. You can’t know truth.

3. No one has the truth.

4. All truth is relative.

5. It’s true for you but not for me.

6. There are no absolutes.

7. No one can know any truth about religion.

8. You can’t know anything for sure.

9. You should doubt everything.

10. Only science can give us truth.

11. You can only know truth through experience.

12. All truth depends on your perspective.

13. You shouldn’t judge.

14. You shouldn’t force your morality on people.

15. You should live and let live.

16. God doesn’t take sides.

17. You shouldn’t try to convert people.

18. That’s just your view.

19. You should be tolerant of all views.

20. It is arrogant to claim to have the truth.

Aaron explains how to respond to each of those! Read them all – it’s important to know, because you hear these all the time.

For further study

debate between a Christian and a postmodern, featuring Christian scholar Peter Williams and a very strange liberal person. This audio really makes it clear why people are opposed to objective truth claims about religion. Williams’ opponent is the epitome of postmodern relativist irrational universalism.

Greg Koukl explains how to be a consistent moral relativist

The absolute easiest way to get into a good apologetics conversation with someone is to ask them what makes something right or wrong on their view.

Here’s a paper by Greg Koukl from Stand to Reason, in which he critiques moral relativism. His paper is called “Seven Things You Can’t Do as a Moral Relativist”. First, let’s see the list of seven things.

  1. You can’t make moral judgments about other people’s moral choices
  2. You can’t complain about God allowing evil and suffering
  3. You can’t blame people or praise people for their moral choices
  4. You can’t claim that any situation is unfair or unjust
  5. You can’t improve your morality
  6. You can’t have meaningful discussions about morality
  7. You can’t promote the obligation to be tolerant

You’ll have to read the paper to see how he argues for these, but I wanted to say a brief word about number 1.

Rule #1: Relativists Can’t Accuse Others of Wrong-Doing

Relativism makes it impossible to criticize the behavior of others, because relativism ultimately denies that there is such a thing as wrong- doing. In other words, if you believe that morality is a matter of personal definition, then you can’t ever again judge the actions of others. Relativists can’t even object on moral grounds to racism. After all, what sense can be made of the judgment “apartheid is wrong” when spoken by someone who doesn’t believe in right and wrong? What justification is there to intervene? Certainly not human rights, for there are no such things as rights. Relativism is the ultimate pro-choice position because it accepts every personal choice—even the choice to be racist.

In moral relativism, what you ought to do is totally up to you. Morality is just like a lunch buffet – you pick what you like based on your personal preferences.

I remember one particular discussion I had with a non-Christian co-worker. Both she and her live-in boyfriend were moral relativists. They were fighting because she was angry about his not having (or wanting) a job, and he was angry because when he asked her for space, she immediately ran out and cheated on him.

What’s interesting is that both of these people chose the other in order to escape being judged themselves. I think this happens a lot in relationships today. Both people don’t want to be judged by the other person, but they both want to the other person to treat them well and to honor moral obligations. Isn’t that interesting? I don’t think that you can have something like marriage work when neither person takes moral obligations to the other person seriously.

Walter Bradley asks: what is religion really supposed to be about?

Dr. Walter L. Bradley
Dr. Walter L. Bradley

This lecture is based on the book “Truth in Religion” by famous philosopher Mortimer J. Adler. At the time of writing the book, he was not a Christian, but there is still a lot of value in the book for Christians who are trying to understand what religion should really be about.

About the speaker

The speaker is one of my top 3 favorite speakers of all time in Christian apologetics, Dr. Walter Bradley. (The other two are Dr. Stephen C. Meyer and Dr. Michael Strauss)

Here’s a biography:

Dr. Bradley received his B.S. in Engineering Science and his Ph.D. in Materials Science from the University of Texas in Austin.

Dr. Bradley taught for eight years at the Colorado School of Mines before assuming a position as Professor of Mechanical Engineering at Texas A&M University (TAMU) in 1976.

During his 24 years at Texas A&M, Dr. Bradley served as Head of the Department of Mechanical Engineering at Texas A&M University and as Director of the Polymer Technology Center, and received five College of Engineering Research Awards. He has received over $4,500,000 in research grants and has published over 140 technical articles and book chapters. He has also co-authored “The Mystery Of Life’s Origin: Reassessing Current Theories. He is a Fellow of the American Society for Materials and of the American Scientific Affiliation and serves as a consultant for many Fortune 500 companies.

You can read more about his recent research on how to use coconuts to make car parts in this article from Science Daily.

The MP3 file is here. (31 minutes + Q&A)

Topics:

  • what is pluralism?
  • what is multiculturalism?
  • what is relativism?
  • some propositions are true culturally – just for certain groups in certain times (cultures)
  • some proposition are true trans-culturally – true independently of what anyone wants or feels
  • Mathematical truth is trans-cultural – it is true regardless of cultural fashions
  • Scientific truth is trans-cultural – it is true regardless of cultural fashions
  • Some truths are not like this – cooking traditions, clothing traditions and greeting traditions
  • These kinds of truths are NOT trans-cultural, they vary by culture
  • The question is – is religion true like math and science, or true depending on the culture
  • Some people think that your religion depends on where you were born or what your family believes
  • Religions make conflicting claims about the way the world really is, so they can’t all be true
  • And these conflicts are at the core of the religions – who God is, how can we be related to him, etc.
  • So if religions convey trans-cultural truth, then either one is true or none are true
  • If they are not trying to convey trans-cultural truth, then they are not like math and science
  • Let’s assume that religion is the same as trans-cultural truth
  • How can we know which religion is true? 1) the laws of logic, 2) empirical testing against reality
  • Logical consistency is needed to make the first cut – self-contradictory claims cannot be true
  • To be true trans-culturally, a proposition must at least NOT break the law of non-contradiction
  • According to Mortimer Adler’s book, only Christianity, Judaism and Islam are not self-contradictory
  • All the others can be excluded on the basis of overt internal contradictions on fundamental questions
  • The others that are self-contradictory can be true culturally, but not trans-culturally
  • The way to proceed forward is to test the three non-contradictory religions against science and history
  • One of these three may be true, or they could all be false
  • We can test the three by evaluating their conflicting truth claims about the historical Jesus
  • Famous skeptics have undertaken studies to undermine the historical Jesus presented in the Bible
  • Lew Wallace, Simon Greenleaf and Frank Morrison assessed the evidence as atheists and became Christians
  • There is a lot of opposition in culture to the idea that one religion might be true
  • But if you take the claims of Jesus at face value, he claims to be the unique revelation of God to mankind
  • Either he was telling the truth about that, or he was lying, or he was crazy
  • So which is it?

Why don’t religious people ask if their religion is true?

People seem to be chicken these days about claiming that their religion is true. It’s easier to say that my religion is true for me, and your religion is true for you – reduce it to personal preferences. So long as everyone is sincere about what they believe, then that’s the most important thing, right?

But it is NOT TRUE that you can believe whatever you want as long as you are sincere – sincerity doesn’t mean that you can’t be mistaken. I can jump off the top of the Sears Tower and be sincere in my belief that I will float down like a feather, but that doesn’t make my belief true. If you want to have a good relationship with God, you have to know things about him, not just have sincere beliefs. You have to know whether he exists and what he is like – really. It’s not enough to have sincere beliefs that are not actually true.

I think that God’s existence and character can be assessed and known based on logic and evidence. I think that God exists independently of whether I want him to or not, and I think that his character and desires are not the same as my character and desires. And I don’t really care what my neighbors think of my disagreeing with them, my goal is not to keep silent and to just get along with them and be happier in my community.

God’s first commandment to us is not to love our neighbor – that’s number two. Number one is to love him. And how can we love him, if we don’t want to know him. And how can we love him, if we don’t tell people the truth about him when they ask us?

That message is not going to win us a lot of friends, but our job as Christians is to tell how and why God stepped into history. Jesus expects us to be his ambassadors and to carry out the task of evangelism faithfully, and to suffer with him and – if necessary – to be rejected like he was rejected.
