I've never heard God speak out loud to me. That's not an experience I have had.

C.S. Lewis had a big influence on me in this spiritual realm - this sort of sense of longing. A longing for a knowledge that is just outside of our reach, a knowledge for a spiritual connection.

We give our kids vaccinations. That's a biological enhancement that's considered not just acceptable but actually admirable.

People who are in a position of finding out that they're at risk for some illness, whether it's breast cancer, or heart disease, are afraid to get that information - even though it might be useful to them - because of fears that they'll lose their health insurance or their job.

When does life begin? When does the soul enter? That's a religious question. Science is not going to be able to help with that.

When you make a breakthrough it is a moment of scientific exhilaration because you have been on this search and seem to have found it. But it is also a moment where I at least feel closeness to the creator in the sense of having now perceived something that no human knew before but God knew all along.

A lot of science doesn't require big "ns" but if you're trying to understand something about human health and you're looking at interventions that are not going to be either killing you or making you live forever - they're going to have some tweaking on the outcome - you need big numbers or you don't have enough power.
