I don't know whether I'm misanthropic. It seems to me I'm constantly disappointed. I'm very easily disappointed. Disappointed in the things that people do; disappointed in the things that people construct. I want things to be better all the time.

Roads get wider and busier and less friendly to pedestrians. And all of the development based around cars, like big sprawling shopping malls. Everything seems to be designed for the benefit of the automobile and not the benefit of the human being.

Anyone who has read my books will know that I don't tend to use guides when I am travelling. It's not a pride thing, but it is certainly a fact.

You can be a scientist and believe in god: the two can go hand in hand.

It's hard not to be kind of pessimistic about human beings generally, because we do tend to mess things up. If you just look at the history of extinctions, we've killed off an awful lot of animals - and I don't think we're doing a very good job of looking after the planet.

[The Royal Society] is quite simply the voice of science in Britain. It is intellectually rigorous, not afraid to be outspoken on controversial issues such as climate change, but it is not aggressively secular either, insisting on a single view of the world. In fact, there are plenty of eminent scientists - Robert Winston, for instance - who are also men of faith.

Of all the things I am not very good at, living in the real world is perhaps the most outstanding.
