William Lane Craig lectures on the postmodern challenge to belief in God

In a lecture entitled “Are there Objective Truths About God?”, philosopher William Lane Craig responds to postmodern challenges to the idea of truth, and specifically to the idea that religion is about objective truth.

Here’s the link to a page containing the lecture audio. (H/T Be Thinking)

The MP3 file is here.

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.

Are there objective truths about God?

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. Christianity is different – we are used to having to defend our truth claims using evidence, because that is the core of the religion, and the example of the founder and his closest followers.

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 judgemental” and “you’re arrogant”. These are just shorthand ways of saying, “I’m offended that you think that what you believe is true and you think that what I believe is false”. They would never say that in a math classroom or a chemistry lab, where truth matters. But because they are coming to the discussion with the presupposition that religion is like clothing and diet preferences, they take everything personally instead of treating religion as something objective, just like any other area of knowledge.

This problem of being offended by truth claims is especially common with people who are raised to think that their religion is a racial, national or cultural identity. They haven’t thought anything through, or considered any alternatives, and they think that if you tell them they are wrong  on matters of fact that somehow this amounts to some sort of racism, intolerance 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. For many non-Christians, religion is not about truth at all but about personal preferences – and they cannot understand why Christians say that they have to go to Hell for having the wrong personal preferences. You have to tell them that religion is about truth, and that people displease God because they don’t know what is true, and they don’t want to know what is true. Then they understand why you are disagreeing with them and you can have a conversation about what is true.

Pro-life debater Scott Klusendorf discusses pro-life apologetics

Did you know that the pro-life issue is an area where you can learn arguments and use evidence to be persuasive? Here’s a podcast that shows you how.

Details:

Scott Klusendorf, President of Life Training Institute, is a pro-life rockstar. Listen in as host Brian Fisher attempts to unsuccessfully “stump the apologist” with some of the most difficult pro-abortion questions of our day.

The MP3 file is here. (36 minutes)

Questions:

  • How did Scott get interested in the abortion issue?
  • Do you need a special calling in order to learn how to defend the unborn?
  • What is the history of the pro-life movement, and how have they shifted tactics?
  • What is moral relativism? How is it relevant to the abortion debate?
  • Why is moral relativism so widely accepted?
  • How do you deal with someone who says abortion is wrong, but she has no choice?
  • How do you deal with the rape and incest exceptions argument?
  • What about unborn children who are not “viable”?
  • But isn’t the foetus part of the woman’s body?
  • Abortion is necessary to reduce poverty, crime, overpopulation, etc.

It’s Friday night, and listening to a smart pro-lifer is awesome. His answer to the abortion is necessary to alleviate poverty is just awesome – the man is widely read outside his field.

 

 

John Lennox and Paul Davies discuss aliens and the origin of life

An amazing debate about the origin of life and the cosmic fine-tuning between a Christian and a materialist agnostic. John Lennox is AWESOME in this debate, and he only talks for a tiny part of the debate. He’s very gracious, and focused the discussion on the areas that we care about. Paul Davies is an EXCELLENT scientist and well aware of what Christians believe. This is a great debate, very easy to listen to. Justin, the moderator, does a great job controlling a fantastic discussion.

The MP3 file is here.

What does it take for life to get going in our universe? Is there intelligence in the stars or right under our nose? Renowned astrophysicist Paul Davies chats to Oxford Professor of Mathematics John Lennox.

A popular science author, Davies is also the Chair of the SETI post detection task force. His latest book “The Eerie Silence” which marks SETI’s 50th anniversary examines the likelihood of the universe producing life elsewhere.

John Lennox is a Christian Mathematician and philosopher. He is the author of “God’s Undertaker: has science buried God?” and has debated Richard Dawkins on several occasions.

Davies’ work on the fine tuning of the universe for life has been sympathetic to theism. In this programme Lennox challenges Davies to look to design not just in cosmology but in the cell. They also chat about what the discovery of ET would mean for Christian theology.

Summary

Justin:

  • Is there meaning in the universe?

Paul:

  • We have no evidence for or against intelligent life elsewhere in the universe
  • The vastness of the universe makes me think there is life elsewhere
  • Humans are capable of observing and understanding the universe
  • It seems the universe has the ability to create observers to understand it
  • If one species has this ability, then we should expect others to do it

John:

  • The fact that we can observe the universe and do science has cosmic significance
  • Our rare habitable planet and our ability to do science is suggestive of purpose
  • So science itself points to an extra-terrestrial intelligence: GOD
  • The complexity of life and consciousness itself points away from atheism
  • Monotheism gave birth to science
  • Human minds capable of doing science are not compatible with atheistic materialism

Justin:

  • Why do you say that either we are the only life or there are many different kinds of life?

Paul:

  • There are lots of factors that have to be met to have a site for simple life
  • These are related to the fine-tuning of cosmic constants, e.g. gravitational force
  • But there are also factors that have to be met for originating intelligent life
  • Things like convergence, self-organization, etc.
  • So the cosmic requirements and evolutionary requirements are different
  • Darwinian evolution doesn’t solve the problem of the origin of life
  • 50 years ago, skepticism about alien life existing anywhere was excessive
  • Today, credulity about alien life exiting everywhere is excessive
  • The naturalist is searching for a process that creates life easily

John:

  • Paul agrees that there is no theory for a naturalistic origin of life
  • This is fatal for the idea that life can emerge elsewhere in the universe
  • We have not discovered any law that produces life without an intelligence
  • Consider the method used by SETI used to detect an alien intelligence
  • Why can’t this method be applied to the origin of life on Earth?
  • Why can’t an intelligence created specified complexity (functional information)?
  • Why can’t an intelligence created epigenetics and protein folding?

Paul:

  • Darwinian evolution can add new biological information after life begins

John:

  • Darwinian evolution assumes a mutating replicating life form to act on

Paul:

  • You can’t generate specified complexity by using physical laws
  • You can’t generate specified complexity by chance
  • At this point we are guessing as to how life might have formed

John:

  • Why do we have to rule out an intelligent cause a priori
  • If you can recognize an intelligence in outer space, why not in living systems?

Paul:

  • I don’t mind the word “intelligence”, it’s the word “signal”
  • I oppose the idea that God or aliens manipulated physical stuff to create life
  • It’s an “ugly explanation and very unappealing both theologically and scientifically”
  • I prefer the idea that the universe has processes to self-organize and create complexity
  • When it comes to supernatural meddling by God, “I don’t want that”
  • If I were God, I would create the universe so that I would not have to intervene
  • I think God would be more clever if he did not have to intervene
  • My preferences about what is “clever” determines what scientific conclusions are allowed

John:

  • Humans already have experience with their non-material minds to move atoms (matter)
  • If God is a mind, then there is no reason why he cannot move atoms (matter)

Paul:

  • My mind is physical, so are you saying that God is physical?
  • If God intervenes in the universe, then what is he doing now?

John:

  • There is a distinction between acts of creation and providential upholding the universe
  • God is also speaking to people and drawing humans toward him
  • God is spirit, not material

Paul:

  • How can a non-physical entity cause effects on the physical world?

John:

  • What science reveals that there is information needed for the origin of life
  • Information requires an intelligence to create it, just as with human who write books
  • That’s not God of the gaps – it’s an inference based on what we know today

Paul:

  • We may be able to explain the origin of life later, using matter, law and chance
  • What you’re saying is that God tinkers with the genome
  • If you say that God intervened once, then he intervenes all the time, everywhere!
  • I don’t want a God who tinkers in the genome
  • if God could intervene in the universe that would remove its intelligibility

John:

  • Look at the cover of this book – when I read words, I infer an intelligence
  • There are bad gaps that the progress of science closes
  • There are good gaps that science opens, showing the need for intelligence
  • On the one hand, you say we have no theory of the origin of life
  • On the other hand, you know that an intelligent designer wasn’t involved
  • If we don’t know how life began, why do you rule God out a priori?

Paul:

  • What scientists want to do is to explain the universe without involving God
  • naturalists want to use science to discover only materialist explanations
  • The purpose of SETI is to prove that there is other life in the universe
  • This would then show that there is a naturalistic way of making life
  • I agree that information in living systems is real hard to explain materialistically
  • I believe in the power of emergence
  • We might discover laws that prove that complexity can emerge without intelligence
  • The discovery of alien life would help to show that no intelligence is needed to make life

Justin:

  • What sort of cosmic fine-tuning is needed at the Big Bang for life to occur?

Paul:

  • It’s true that the universe appears extremely fine-tuned for life to exist
  • The typical answer from naturalists is that there is a multiverse
  • But the multiverse “falls far short” of providing a good answer to the fine-tuning
  • It’s irrational to appeal to massive numbers of unseen universes to explain fine-tuning
  • The design and purpose seen in the universe may be due to God or it may be emergent

John:

  • The fine-tuning is real and the multiverse is a desperate attempt to evade the creator
  • Sir Martin Rees (an atheist) says he “prefers” the multiverse to a designer
  • Scientists are not supposed to prefer anything except what is true

Justin:

  • Would the discovery of aliens hurt Christianity, because of the belief in the uniqueness of humans?

Paul:

  • Christians believe that Jesus came to save HUMANS specifically, not animals or aliens
  • If we were to discover intelligent aliens, it would challenge traditional religions
  • What will God do with alien races? Multiple incarnations? Or just preach the gospel to them?

John:

  • We don’t know if the aliens exist, first of all – it’s speculative
  • The Bible teaches that humans bear the image of God
  • We just don’t know whether alien species are also made in God’s image
