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.

I'm enormously interested to see where neuroscience can take us in understanding these complexities of the human brain and how it works, but I do think there may be limits in terms of what science can tell us about what does good and evil mean anyway, and what are those concepts about?

[The tests agreed] that I was at higher risk than the average person for Type 2 diabetes, which is what my lab works on. In fact, some of the things they were testing for were variants that we had discovered.

As you kind of get over the anxiety about [science and evolution], it actually adds to your sense of awe about this amazing universe that we live in, it doesn't subtract from it at all.

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.

Science's tools will never prove or disprove God's existence.

The human genome will not help us to understand the spiritual side of humankind, or to know who God is or what love is. The well-heeled couple who decide they want to use genetics to have a child that is a gifted musician may end up with a sullen adolescent who smokes marijuana and doesn't talk to them.
