Growing up, I was vaguely aware of things that went on in church, because I was in the boys' choir at the local Episcopal church. But I got the clear message that I was supposed to learn music there, and not pay too much attention to the rest of it, and I followed those instructions very carefully.

I believe God did intend, in giving us intelligence, to give us the opportunity to investigate and appreciate the wonders of His creation. He is not threatened by our scientific adventures.

The brain is the most complicated organ in the universe. We have learned a lot about other human organs. We know how the heart pumps and how the kidney does what it does. To a certain degree, we have read the letters of the human genome. But the brain has 100 billion neurons. Each one of those has about 10,000 connections.

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

A permanent base on Mars would have a number of advantages beyond being a bonanza for planetary science and geology. If, as some evidence suggests, exotic micro-organisms have arisen independently of terrestrial life, studying them could revolutionise biology, medicine and biotechnology.

No honest writer today can possibly avoid being influenced by Freud through his pioneering work into the Unconscious and by the influence of those discoveries on the scientific, philosophic, and artistic work of his contemporaries: but not, by any means, necessarily through Freud's own writing.

Just after graduation in 1966, like many of my contemporaries, I applied for research training at the National Institutes of Health. Perhaps because his wife was a poet, Ira Pastan agreed to take me into his laboratory, despite my lack of scientific credentials.

It really gets on my goat that people keep quoting Dorothea Mackellar's 'My Country' as proof that there is no such thing as climate change. A poem written more than 100 years ago by a homesick 19 year old versus an ever-increasing body of refereed scientific thought... hmm, hard to know which way to jump, really.
