Suddenly, in the space of a moment, I realized what it was that I loved about Britain - which is to say, all of it. Every last bit of it, good and bad - old churches, country lanes, people saying 'Mustn't grumble,' and 'I'm terribly sorry but,' people apologizing to ME when I conk them with a careless elbow, milk in bottles, beans on toast, haymaking in June, seaside piers, Ordnance Survey maps, tea and crumpets, summer showers and foggy winter evenings - every bit of it.

Human beings would split the atom and invent television, nylon, and instant coffee before they could figure out the age of their own planet.

Think of a single problem confronting the world today. Disease, poverty, global warming... If the problem is going to be solved, it is science that is going to solve it. Scientists tend to be unappreciated in the world at large, but you can hardly overstate the importance of the work they do. If anyone ever cures cancer, it will be a guy with a science degree. Or a woman with a science degree.

When you consider it from a human perspective, and clearly it would be difficult for us to do otherwise, life is an odd thing. It couldn't wait to get going, but then, having gotten going, it seemed in very little hurry to move on.

You can always tell a Midwestern couple in Europe because they will be standing on a traffic island in the middle of a busy intersection looking at a windblown map and arguing over which way is west. European cities, with their wandering streets and undisciplined alleys, drive Midwesterners practically insane.

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. As humans we are doubly lucky, of course: We enjoy not only the privilege of existence but also the singular ability to appreciate it and even, in a multitude of ways, to make it better. It is a talent we have only barely begun to grasp.
