“The average Southerner has the speech patterns of someone slipping in and out of consciousness. I can change my shoes and socks faster than most people in Mississippi can speak a sentence.”

Most of what has lived on Earth has left behind no record at all.

If this book has a lesson, it is that we are awfully lucky to be here-and by ‘we’ I mean every living thing. To attain any kind of life in this universe of ours appears to be quite an achievement.

The lesson to draw from this, of course, is that when you move from one country to another you have to accept that there are some things that are better and some things worse, and there is nothing you can do about it.

Britain still has the most reliably beautiful countryside of anywhere in the world. I would hate to be part of the generation that allowed that to be lost.

If you were designing an organism to look after life in our lonely cosmos, to monitor where it is going and keep a record of where it has been, you wouldn’t choose human beings for the job.

It was one of those sumptuous days when the world is full of autumn muskiness and tangy, crisp perfection: vivid blue sky, deep green fields, leaves in a thousand luminous hues. It is a truly astounding sight when every tree in a landscape becomes individual.

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

I can wear a baseball cap; I am entitled to wear a baseball cap. I am genetically pre-disposed to wear a baseball cap, whereas most English people look wrong in a baseball cap.

In terms of adaptability, humans are pretty amazingly useless.

It was the kind of pure, undiffused light that can only come from a really hot blue sky, the kind that makes even a concrete highway painful to behold and turns every distant reflective surface into a little glint of flame.

I see litter as part of a long continuum of anti-social behaviour.

I had spent the whole of my savings … on a suit for the wedding – a remarkable piece of apparel with lapels that had been modelled on the tail fins of a 1957 Coupe de Ville and trousers so copiously flared that when I walked you didn’t see my legs move.

Every living thing is an elaboration of a single original plan. As humans we are mere increments – each of us a musty archive of adjustments, adaptations, modifications and providential tinkerings stretching back to 3,8 billion years.

If you drive to, say, Shenandoah National Park, or the Great Smoky Mountains, you’ll get some appreciation for the scale and beauty of the outdoors.

Language is more fashion than science, and matters of usage, spelling and pronunciation tend to wander around like hemlines.
