When describing her own Christian faith, Rosalind Picard, a Professor at the MIT Media Lab, said that ‘I know some people will assume I have lost my marbles…I also know that if they move beyond such superficial characterisations and ask hard questions, the ones about real meaning and purpose, that they will see more of what I see.’ That is how I feel in trying to describe my own faith. I’ve already given some hints about what I believe in previous blogs, but I thought it would be good to spell it out a bit more.
How can a scientist be a Christian? W.K. Clifford, a mathematician and philosopher at University College London in the nineteenth century, said that ‘it is wrong always, everywhere, and for everyone, to believe anything on insufficient evidence’. I agree with Clifford, although Continue reading →
I’ve been getting some useful feedback on these posts, and I would particularly appreciate your input on this one. It’s an illustration that I’ve been using in a number of talks recently.
This is a cartoon of the molecular structure of DNA. Obviously no one has ever seen it – it’s too small even for the most powerful of microscopes. It was discovered by James Watson and Francis Crick (and several others) using x-ray crystallography in crystals of DNA. After their famous Nature paper was published, the science of molecular biology flourished and Watson and Crick’s model for the structure of DNA was tested in many ways. Now we have so much evidence for the double helical structure of DNA that no biologist would doubt it.
The structure of DNA hasn’t been ‘proved’. You can only prove things using maths. Science is about disproving things – narrowing down the options and getting nearer the truth. So in a way we believe that DNA is a double helix by faith – faith that is well founded on the ‘laws’ of physics, and lots and lots and lots of reliable evidence. I’d be fairly confident to stake my life on it (though I can’t imagine why I’d need to…)
What does that have to do with Christianity? This is something that I do stake my life on, so I’d better be sure it’s worth believing. Like science, none of the interesting questions in life – ‘Is that a great painting?’ ‘Does that person love me?’ ‘Is there a God?’ – can be solved mathematically. But I think there’s plenty of evidence to back up the claims of Christianity in history, archaeology, answers to prayer, the study of the Bible, and so the list goes on. For me the most important evidence is the way in which God changes lives. When someone you know well becomes a Christian you have the opportunity to see whether Jesus’ claims are true – first hand. I’ve seen it happen over and over again. That’s the reason why I’m a Christian, and why I think science and Christianity have something in common.
