Diary Of A CEO: w/ Mathematician John Lennox – June 4, 2026 (Transcript)

Editor’s Note: In this episode of The Diary Of A CEO, host Steven Bartlett sits down with mathematician and Christian apologist John Lennox for a profound exploration of human existence in the age of artificial intelligence. Together, they navigate complex questions surrounding faith, morality, the rapid advancements of AI, and whether technology can truly satisfy the human search for meaning and purpose.

TRANSCRIPT:

John Lennox on Mathematics, Faith, and the Future of AI

STEVEN BARTLETT: John Lennox. You’ve published over 70 peer-reviewed mathematical papers, co-authored 2 research texts at the Oxford Mathematical Monograph Series, and you’ve really become a pioneer in many domains through your career. But for anyone that doesn’t know you, what is the most important context they need to understand the reference points, experience, education that you’re pulling on that is going to inform all of the subjects we talk about today?

JOHN LENNOX: I mean, I’ve written a number of papers. I got a certain amount of international recognition. I chaired Oxford and all the rest of it. But I think the real value of that has been the training in logic, really saying that mathematics works. The fact that it works is for me one of the strongest evidences that this is what I call a word-based universe.

We can use mathematics to describe things about how the universe works, thinking God’s thoughts after him, Kepler’s famous statement. But also we’ve lived to see a biological revolution where we discover biology’s word-based as well with the human genome. And that to me resonates with the explanation given in both the Old Testament and the New. Language of John’s Gospel, “In the beginning was the word.”

Steven’s Personal Background with Faith

STEVEN BARTLETT: I don’t know a ton about the Bible. I do come from a religious family.

JOHN LENNOX: Do you? Right, okay.

STEVEN BARTLETT: We grew up as Christians. I think I lost my faith at about 18 years old. ‘Cause you know me, my brothers are extremely good at maths. They’re very rational thinking, maybe to a fault. And I think maybe I am a little bit too.

JOHN LENNOX: I am too.

STEVEN BARTLETT: You are? This is why I find it so fascinating. ‘Cause typically the scientific community lean more towards atheism. And typically I think that mathematicians lean more towards atheism. Just to sense check if that’s true or not, we’ll throw the numbers up on the screen. So I find that to be a fascinating conversation, which I’m looking forward to have with you today.

Interestingly, you wrote this book and the word AI is on it. It says God, AI, and the End of History. Why are you so concerned, dare I say, about artificial intelligence as a leading pioneer in maths and sort of philosophical thinking?

The Drive for Artificial General Intelligence and Transhumanism

JOHN LENNOX: Well, because I’m interested in the bigger picture. Anything that raises questions about the nature of human identity. And I was first struck by the drive for artificial general intelligence. It’s really become one of the— it looks as if it’s the prime motivation of people like Sam Altman and so on. It is really hitting the headlines. But within that, there’s the notion of transhumanism.

STEVEN BARTLETT: What does that mean?

JOHN LENNOX: The idea is that we go beyond the human. One of our most famous astronomers, Royal, he put it this way. He says in the distant future, it won’t be organic brains, it’ll be machine brains. And he seriously believes, as do a number of scientists who are not science fiction authors, that there will be some kind of merger between humanity and machines to have a transhuman, something that’s beyond the human. And something that is, they hope, super intelligent, got all the human properties and much more.

Now, one of the people who’s spreading that kind of transhumanist vision is the Israeli historian Yuval Noah Harari, and he’s written a book called Homo Deus: The Man-God. And that really made me prick up my ears because I know enough about this book here, the Bible, to realize that the drive for humans towards self-deification is—

STEVEN BARTLETT: Self-deification.

JOHN LENNOX: Yes, making themselves gods. And you see it all through history. The ancient Babylonian emperors were regarded as gods. The Roman emperors started calling themselves gods and all the rest of it. And what Harari says is the 21st century has two big purposes. Number one, to solve the problem of physical death as a technical problem.

STEVEN BARTLETT: To solve death.

JOHN LENNOX: Yes, solve death. Physical death is, in his view, a technical problem and we’ll solve it. The second agenda item, and he calls them agenda items for the 21st century, is to increase human happiness by bioengineering, cyborg engineering, mechanical implants, all this kind of thing, and turning humans, quote, into gods with a small g. In other words, this is the drive for a super intelligent human.

We’ve only got started. And his point is, and from his atheist perspective one can understand it immediately, evolution, unguided natural processes have brought us to this point. Now we’re going to take it into our hands and we’re to engineer humanity into the future very rapidly to approach this superhuman thing.

Now, I hear that and I see that, but I see that as huge implications for one of the fundamental teachings that’s behind, I would argue, Western civilization, and that is the notion that humans like us are made in the image of God as rational, moral beings.

Now, I got into this because some Christian leaders wanted to have a conference on AI, and they wanted it introduced from someone who knew something about the teaching of the image of God in Genesis and who had a scientific background and who could perhaps begin to lead them into what was going on in the AI field around.
