Research is so unpredictable. There are periods when nothing works and all your experiments are a disaster and all your hypotheses are wrong.

The problem [with genetic research] is, we're just starting down this path, feeling our way in the dark. We have a small lantern in the form of a gene, but the lantern doesn't penetrate more than a couple of hundred feet. We don't know whether we're going to encounter chasms, rock walls or mountain ranges along the way. We don't even know how long the path is.

I trained initially as a physical chemist, and then, after becoming interested in biology, I went to medical school and learned how to be a physician. So, I'm a physician scientist.

It's interesting when you read the life of Christ how much of his time he spent healing the sick. There must have been a reason for that - he was modelling for us what it is we are intended to do by following his path.

If God made the natural laws, why could he not violate them when it was a particularly significant moment for him to do so? And if you accept the idea that Christ was also divine, which I do, then his Resurrection is not in itself a great logical leap.

What faith has not been used by demagogues as a club over somebody's head?

If God is real, and I believe he is, then he is outside of nature. He is, therefore, not limited by the laws of nature in the way that we are.
