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

Christianity and the progress of science
Christianity and the progress of science

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.

Details

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

Have you heard about Dr. Angus Menuge’s ontological argument against naturalism?

Soldiers of the 101st Airborne Division test the new M-17 pistol

My friend Seth mentioned to me that he likes the argument from reason, so I thought I would post something about it from a Christian scholar who I really admire. Dr. Angus Menuge offers the best (I think) argument for the proposition that theism is the best ground for our reasoning capability.

Let’s start with some information about Dr. Menuge:

Dr. Angus Menuge joined Concordia University Wisconsin in 1991. He earned his BA from the University of Warwick, England, and his MA and Ph.D. degrees from the University of Wisconsin-Madison, where he studied philosophy, computer science and psychology. Menuge’s dissertation was on the philosophy of action explanation, and his current research interests include philosophy of mind, philosophy of science and Christian apologetics.

In 2003, Menuge earned a Diploma in Christian Apologetics from the International Academy of Apologetics, Evangelism and Human Rights, which meets each July in Strasbourg, France. His thesis, a critique of scientific materialism, went on to become the book Agents Under Fire: Materialism and the Rationality of Science (Lanham, MD: Rowman and Littlefield, 2004).

[…]A frequent speaker, Menuge has given presentations on Christianity and culture, science and vocation, philosophy of mind, C. S. Lewis, Intelligent Design and the case against scientific materialism. He is a member of the Evangelical Philosophical Society.

Dr. Menuge presented a paper at a recent Evangelical Philosophical Society conference for students and professors of philosophy, and you can download the paper here as a PDF. I got these straight from the source, and got permission to post them, too.

Here is the introduction to the paper that Dr. Menuge read at the EPS conference:

The argument from reason is really a family of arguments to show that reasoning is incompatible with naturalism. Here, naturalism is understood as the idea that foundationally, there are only physical objects, properties and relations, and anything else reduces to, supervenes on, or emerges from that. For our purposes, one of the most important claims of naturalism is that all causation is passive, automatic, event causation (an earthquake automatically causes a tidal wave; the tidal wave responds passively): there are no agent causes, where something does not happen automatically but only because the agent exerts his active power by choosing to do it. The most famous version of the argument from reason is epistemological: if naturalism were true, we could not be justified in believing it. Today, I want to focus on the ontological argument from reason, which asserts that there cannot be reasoning in a naturalistic world, because reasoning requires libertarian free will, and this in turn requires a unified, enduring self with active power.

The two most promising ways out of this argument are: (1) Compatibilism—even in a deterministic, naturalistic world, humans are capable of free acts of reason if their minds are responsive to rational causes; (2) Libertarian Naturalism—a self with libertarian free will emerges from the brain. I argue that neither of these moves works, and so, unless someone has a better idea, the ontological argument from reason stands.

The paper is 11 pages long, and it is awesome for those of you looking for some good discussion of one of the issues in the area of philosophy of mind.

By the way, the epistemological argument from reason (P(R) on N & E is low) is the argument made by the famous Christian philosopher Alvin Plantinga. I blogged about that argument before. It’s good to know BOTH of these arguments. They both work, and they are both awesome. If you put these two arguments together with William Lane Craig’s moral argument, that’s three strong philosophical arguments that are easy to use, but backed by solid analytic philosophy.

But there is more than just the paper! At the EPS apologetics conference, which is meant for lay people as well as scholars, he presented this slideshow which I converted to PDF. The slides are easier to understand than the paper, but the paper is not too bad.

Audio from Apologetics 315

Click here for an interview with Dr. Menuge. It’s up at Apologetics 315!

Details:

Today’s interview is with Dr. Angus Menuge, Professor of Philosophy  at Concordia University, and author of Agents Under Fire: Materialism and the Rationality of Science. He talks about his background and work, the philosophy of mind, what reason (or reasoning) is, what materialism is as a worldview, things excluded from a materialistic worldview, methodological naturalism and materialism, accounting for free will, materialistic accounts of reason, the epistemological argument from reason, the ontological argument from reason, finding the best explanation for reason, problems with methodological naturalism, implications of materialism, practical application of the argument from reason, advice for apologists, the International Academy of Apologetics, and more.

If what Dr. Menuge says in this interview is true, and I think it is, then a person who believes in materialism can neither ground free will nor rationality! So atheism wouldn’t really be freethought so much as it would be… un-free… non-thought.

William Lane Craig discusses faith and reason with university students

William Lane Craig lecturing to university students
William Lane Craig lecturing to university students

This is an interview of Dr. William Lane Craig before college students at the University of Central Florida. (95 minutes)

Questions from the interviewer: (40 minutes)

  • What started you on his journey of studying faith and reason?
  • How would you define the word “faith”?
  • Are faith and reason compatible? How are they related?
  • How can reasonable faith help us to avoid the two extremes of superstition and nihilism?
  • Who makes the best arguments against the Christian faith?
  • Why are angry atheists like Dawkins and Hitchens more well known than better-informed academic atheists?
  • Does the Bible require Christians to give the unbeliever reasons for their faith?
  • How does faith spur Christians to think carefully about the big questions in life?
  • Should the American church prod churchgoers to develop their minds so they can engage the secular culture?
  • When talking about Christianity intellectually, is there a risk of neglecting the experience of being a Christian?
  • Which Christian apologist has shaped your thinking the most?
  • Which Christian philosopher has shaped your thinking the most?
  • Does the confidence that comes from apologetics undermine humility and reverence?
  • If you had to sketch out a 5 minute case for Christianity, what would you present?
  • Can non-Christians use their reason to arrive at truth?
  • Are there cases where atheists must affirm irrational things in order to remain atheists?
  • Can the universe have existed eternal, so that there is no need to explain who created it?
  • Even if you persuade someone that Christianity is true, does that mean they will live it out?

There is also a long period of questions, many of them hostile, from the audience of students (55 minutes).

  • Haven’t you said nasty things about some atheists? Aren’t you a meany?
  • What do you make of the presuppositional approach to apologetics?
  • Can a person stop being a Christian because of the chances that happen to them as they age?
  • Why did God wait so long after humans appeared to reveal himself to people through Jesus?
  • Can a person be saved by faith without have any intellectual assent to truth?
  • How do you find time for regular things like marriage when you have to study and speak so much?
  • How would you respond to Zeitgeist and parallels to Christianity in Greek/Roman mythology?
  • Do Christians have to assume that the Bible is inerrant and inspired in order to evangelize?
  • If the universe has a beginning, then why doesn’t God have a beginning?
  • Can you name some philosophical resources on abstract objects, Platonism and nominalism?
  • How can you know that Christianity more right than other religions?
  • Should we respond to the problem of evil by saying that our moral notions are different from God’s?
  • Define the A and B theories of time. Explain how they relate to the kalam cosmological argument.
  • How can Christians claim that their view is true in the face of so many world religions?
  • What is the role of emotions in Christian belief and thought?
  • Can evolution be reconciled with Christian beliefs and the Bible?
  • When witnessing person-to-person, should you balance apologetics with personal testimony?
  • Is there a good analogy for the trinity that can help people to understand it? [Note: HE HAS ONE!]
  • How can Christians reconcile God’s omniscience, God’s sovereignty and human free will?

This is a nice introductory lecture that is sure to get Christians to become interested in apologetics. As you watch or listen to it, imagine what the world would be like if every Christian could answer the questions of skeptical college students and professors like Dr. Craig. What would non-Christians think about Christianity if every Christian had studied these issues like Dr. Craig? Why aren’t we making an effort to study these things so that we can answer these questions?

It is really fun to see him fielding the questions from the skeptical university students. My favorite question was from the physics student who sounds really foreign, (at 1:19:00), then you realize that he is a Christian. I do think that Dr. Craig went a little far in accommodating evolution, but I put that down to the venue, and not wanting to get into a peripheral issue. I’m also surprised that no one asked him why God allows humans to suffer and commit acts of evil.

If you are looking for a good basic book on apologetics, then I would choose “Is God Just a Human Invention?” by Sean McDowell and Jonathan Morrow.

Who is William Lane Craig?

About William Lane Craig:

William Lane Craig is Research Professor of Philosophy at Talbot School of Theology in La Mirada, California.

Dr. Craig pursued his undergraduate studies at Wheaton College (B.A. 1971) and graduate studies at Trinity Evangelical Divinity School (M.A. 1974; M.A. 1975), the University of Birmingham (England) (Ph.D. 1977), and the University of Munich (Germany) (D.Theol. 1984). From 1980-86 he taught Philosophy of Religion at Trinity… In 1987 they moved to Brussels, Belgium, where Dr. Craig pursued research at the University of Louvain until assuming his position at Talbot in 1994.

He has authored or edited over thirty books, including The Kalam Cosmological ArgumentAssessing the New Testament Evidence for the Historicity of the Resurrection of JesusDivine Foreknowledge and Human FreedomTheism, Atheism and Big Bang Cosmology; and God, Time and Eternity, as well as over a hundred articles in professional journals of philosophy and theology, including The Journal of PhilosophyNew Testament StudiesJournal for the Study of the New TestamentAmerican Philosophical QuarterlyPhilosophical StudiesPhilosophy, and British Journal for Philosophy of Science.

Craig’s CV is here.

Craig’s list of publications is here.

William Lane Craig is, without a doubt, the top living defender of Christianity. He has debated all of the most famous atheists, including Christopher Hitchens, Sam Harris, etc. as well as academic atheists like Quentin Smith, Peter Millican, etc. if you search this blog, you’ll find many debates posted here, sometimes even with snarky summaries.

William Lane Craig debates Austin Dacey: Does God Exist?

Two tough rams butt heads, and may the best ram win!
Two tough rams butt heads, and may the best ram win!

Here is the video and summary of a debate between Christian theist William Lane Craig and Austin Dacey at Purdue University in 2004 about the existence of God.

The debaters:

The video: (2 hours)

The video shows the speakers and powerpoint slides of their arguments. Austin Dacey is one of the top atheist debaters, and I would put him second to Peter Millican alone, with Walter Sinnott-Armstrong in third place. This is the debate to show people who are new to apologetics. The debate with Peter Millican is better for advanced students, and that’s no surprise since he teaches at Oxford University and is familiar with all of Dr. Craig’s work. The Craig-Dacey debate is the one that I give to my co-workers.

By the way, you can get the DVDs and CDs for the first Craig-Dacey debate and the second Craig-Dacey debate and the second Craig-Sinnott-Armstrong debate. The Peter Millican debate is not available on DVD, but the link above (Peter Millican) has the video and my summary.

Dr. Dacey’s 5 arguments below are all good arguments that you find in the academic literature. He is also an effective and engaging speaker, This is a great debate to watch!

SUMMARY of the opening speeches:

Dr. Craig’s opening statement:

Dr. Craig will present six reasons why God exists:

  1. (Contingency argument) God is the best explanation of why something exists rather than nothing
  2. (Cosmological argument)  God’s existence is implied by the origin of the universe
  3. (Fine-tuning argument) The fine-tuning of the universe for intelligent life points to a designer of the cosmos
  4. (Moral argument) God is the best explanation for the existence of objective moral values and objective moral duties
  5. (Miracles argument) The historical facts surrounding the life, death and resurrection of Jesus
  6. (Religious experience) God’s existence is directly knowable even apart from arguments

Dr. Dacey’s opening argument:

There are two ways to disprove God’s existence, by showing that the concept of God is self-contradictory, or by showing that certain facts about ourselves and the world are incompatible with what we would expect to be true if God did exist. Dr. Dacey will focus on the second kind of argument.

  1. The hiddenness of God
  2. The success of science in explaining nature without needing a supernatural agency
  3. The dependence of mind on physical processes in the brain
  4. Naturalistic evolution
  5. The existence of gratuitous / pointless evil and suffering

One final point:

One thing that I have to point out is that Dr. Dacey quotes Brian Greene during the debate to counter Dr. Craig’s cosmological argument. Dr. Craig could not respond because he can’t see the context of the quote. However, Dr. Craig had a rematch with Dr. Dacey where was able to read the context of the quote and defuse Dr. Dacey’s objection. This is what he wrote in his August 2005 newsletter after the re-match:

The following week, I was off an another three-day trip, this time to California State University at Fresno. As part of a week of campus outreach the Veritas Forum scheduled a debate on the existence of God between me and Austin Dacey, whom I had debated last spring at Purdue University. In preparation for the rematch I adopted two strategies: (1) Since Dacey had come to the Purdue debate with prepared speeches, I decided to throw him for a loop by offering a different set of arguments for God, so that his canned objections wouldn’t apply. I chose to focus on the cosmological argument, giving four separate arguments for the beginning of the universe, and on the evidence for Jesus’ resurrection. (2) I reviewed our previous debate carefully, preparing critiques of his five atheistic arguments. In the process I found that he had seriously misunderstood or misrepresented a statement by a scientist on the Big Bang; so I brought along the book itself in case Dacey quoted this source again. I figured he might change his arguments just as I was doing; but I wanted to be ready in case he used his old arguments again.

[…]The auditorium was packed that night for the debate, and I later learned that there were overflow rooms, too. To my surprise Dr. Dacey gave the very same case he had presented at Purdue; so he really got clobbered on those arguments. Because he wasn’t prepared for my new arguments, he didn’t even respond to two of my arguments for the beginning of the universe, though he did a credible job responding to the others. I was pleased when he attacked the Big Bang by quoting the same scientist as before, because I then held up the book, specified the page number, and proceeded to quote the context to show what the scientist really meant.

Dr. Craig is always prepared!

An atheist explains the real consequences of adopting an atheistic worldview

A conflict of worldviews
A conflict of worldviews

If you love to listen to the Cold Case Christianity podcast, as I do, then you know that in a recent episode, J. Warner Wallace mentioned a blog post on an atheistic blog that clearly delineated the implications of an atheistic worldview. He promised he was going to write about it and link to the post, and he has now done so.

Here is the whole the whole thing that the atheist posted:

“[To] all my Atheist friends.

Let us stop sugar coating it. I know, it’s hard to come out and be blunt with the friendly Theists who frequent sites like this. However in your efforts to “play nice” and “be civil” you actually do them a great disservice.

We are Atheists. We believe that the Universe is a great uncaused, random accident. All life in the Universe past and future are the results of random chance acting on itself. While we acknowledge concepts like morality, politeness, civility seem to exist, we know they do not. Our highly evolved brains imagine that these things have a cause or a use, and they have in the past, they’ve allowed life to continue on this planet for a short blip of time. But make no mistake: all our dreams, loves, opinions, and desires are figments of our primordial imagination. They are fleeting electrical signals that fire across our synapses for a moment in time. They served some purpose in the past. They got us here. That’s it. All human achievement and plans for the future are the result of some ancient, evolved brain and accompanying chemical reactions that once served a survival purpose. Ex: I’ll marry and nurture children because my genes demand reproduction, I’ll create because creativity served a survival advantage to my ancient ape ancestors, I’ll build cities and laws because this allowed my ape grandfather time and peace to reproduce and protect his genes. My only directive is to obey my genes. Eat, sleep, reproduce, die. That is our bible.

We deride the Theists for having created myths and holy books. We imagine ourselves superior. But we too imagine there are reasons to obey laws, be polite, protect the weak etc. Rubbish. We are nurturing a new religion, one where we imagine that such conventions have any basis in reality. Have they allowed life to exist? Absolutely. But who cares? Outside of my greedy little gene’s need to reproduce, there is nothing in my world that stops me from killing you and reproducing with your wife. Only the fear that I might be incarcerated and thus be deprived of the opportunity to do the same with the next guy’s wife stops me. Some of my Atheist friends have fooled themselves into acting like the general population. They live in suburban homes, drive Toyota Camrys, attend school plays. But underneath they know the truth. They are a bag of DNA whose only purpose is to make more of themselves. So be nice if you want. Be involved, have polite conversations, be a model citizen. Just be aware that while technically an Atheist, you are an inferior one. You’re just a little bit less evolved, that’s all. When you are ready to join me, let me know, I’ll be reproducing with your wife.

I know it’s not PC to speak so bluntly about the ramifications of our beliefs, but in our discussions with Theists we sometimes tip toe around what we really know to be factual. Maybe it’s time we Atheists were a little more truthful and let the chips fall where they may. At least that’s what my genes are telling me to say.”

In his post, Wallace comments on the statement above, but for more, you should listen to the podcast.

This fellow is essentially expanding on what Richard Dawkins has said about atheism:

In a universe of blind physical forces and genetic replication, some people are going to get hurt, other people are going to get lucky, and you won’t find any rhyme or reason in it, or any justice. The universe that we observe has precisely the properties we should expect if there is, at bottom, no design, no purpose, no evil and no good, nothing but blind, pitiless indifference… DNA neither knows nor cares. DNA just is. And we dance to its music. (Richard Dawkins, River Out of Eden: A Darwinian View of Life (1995))

And Cornell University atheist William Provine agrees: (this is taken from his debate with Phillip E. Johnson)

Let me summarize my views on what modern evolutionary biology tells us loud and clear — and these are basically Darwin’s views. There are no gods, no purposes, and no goal-directed forces of any kind. There is no life after death. When I die, I am absolutely certain that I am going to be dead. That’s the end of me. There is no ultimate foundation for ethics, no ultimate meaning in life, and no free will for humans, either.

And what about Florida State University atheist Michael Ruse:

“The position of the modern evolutionist is that humans have an awareness of morality because such an awareness of biological worth. Morality is a biological adaptation no less than are hands and feet and teeth. Considered as a rationally justifiable set of claims about an objective something, ethics is illusory. I appreciate when someone says, ‘Love thy neighbor as thyself,’ they think they are referring above and beyond themselves. Nevertheless, such reference is truly without foundation. Morality is just an aid to survival and reproduction, . . . and any deeper meaning is illusory.” (Michael Ruse, “Evolutionary Theory and Christian Ethics,” in The Darwinian Paradigm (London: Routledge, 1989), pp. 262-269).

I see a lot of atheists these days thinking that they can help themselves to a robust notion of consciousness, to real libertarian free will, to objective moral values and duties, to objective human rights, and to objective meaning in life, without giving credit to theism. It’s not rational to do this. As Frank Turek said on the latest episode of “Cross Examined”, atheists have to sit in God’s lap to slap his face. We should be calling them out on it. I think it’s particularly important not to let atheists utter a word of moral judgment on any topic, since they cannot ground an objective standard that allows them to make statements of morality. Further, I think that they should have every immorality ever committed presented to them, and then they should be told “your worldview does not allow you to condemn this as wrong”. They can’t praise anything as right, either. This is not to say that we should go all presuppositional on them, but if the opportunity arises to point out how they are borrowing from theism in order to attack it, we should do that in addition to presenting good scientific and historical evidence.
