“I travel whenever I can - every couple of years if it is possible. I always say I'm not to write books on the countries I visit, but somehow I always seem to use material I can found in these countries in my books.”

“And then, as slowly as the light fades on a calm winter evening, something went out of our relationship. I say that selfishly. Perhaps I started to look for something which had never been there in the first place: passion, romance. I aresay that as I entered my forties I had a sense that somehow life was going past me. I had hardly experienced those emotions which for me have mostly come from reading books or watching television. I suppose that if there was anything unsatisfactory in our marriage, it was in my perception of it—the reality was unchanged. Perhaps I grew up from childhood to manhood too quickly. One minute I was cutting up frogs in the science lab at school, the next I was working for the National Centre for Fisheries Excellence and counting freshwater mussel populations on riverbeds. Somewhere in between, something had passed me by: adolescence, perhaps? Something immature, foolish yet intensely emotive, like those favourite songs I had recalled dimly as if being played on a distant radio, almost too far away to make out the words. I had doubts, yearnings, but I did not know why or what for.Whenever I tried to analyse our lives, and talk about it with Mary, she would say, ‘Darling, you are on the way to becoming one of the leading authorities in the world on caddis fly larvae. Don’t allow anything to deflect you from that. You may be rather inadequately paid, certainly compared with me you are, but excellence in any field is an achievement beyond value.’I don’t know when we started drifting apart.When I told Mary about the project—I mean about researching the possibility of a salmon fishery in the Yemen—something changed. If there was a defining moment in our marriage, then that was it. It was ironical, in a sense. For the first time in my life I was doing something which might bring me international recognition and certainly would make me considerably better off—I could live for years off the lecture circuit alone, if the project was even half successful.Mary didn’t like it. I don’t know what part she didn’t like: the fact I might become more famous than her, the fact I might even become better paid than her. That makes her sound carping.”

“In this country faith is absolute and universal. The choice, if there is a choice, is made at birth. Everyone believes. For these people, God is a near neighbour.I thought of Sundays at home when I was a child, buttoned up in an uncomfortable tweed jacket and forced to go to Sunday communion. I remember mouthing the hymns without really singing, peering between my fingers at the rest of the congregation when I was supposed to be praying, twisting in my seat during the sermon, aching with impatience for the whole boring ritual to be over.I can’t remember when I last went to church. I must have been since Mary and I were married but I can’t remember when. I don’t know anyone who does go to church now. It’s extraordinary, isn’t it? I know I live amongst scientists and civil servants, and Mary’s friends are all bankers or economists, so perhaps we are not typical. You still see people coming out of church on Sunday morning, chatting on the steps, shaking hands with the vicar, as you drive past on your way to get the Sunday papers, relieved you are too old now to be told to go. But no one I know goes any more. We never talk about it. We never think about it. I cannot easily remember the words of the Lord’s Prayer.We have moved on from religion.Instead of going to church, which would never occur to us, Mary and I go to Tesco together on Sundays. At least, that is what we did when she still lived in London. We never have time to shop during the week and Saturdays are too busy. But on Sunday our local Tesco is just quiet enough to get round without being hit in the ankles all the time by other people’s shopping carts.We take our time wheeling the shopping cart around the vast cavern, goggling at the flatscreen TVs we cannot afford, occasionally tossing some minor luxury into the trolley that we can afford but not justify.I suppose shopping in Tesco on Sunday morning is in itself a sort of meditative experience: in some way a shared moment with the hundreds of other shoppers all wheeling their shopping carts, and a shared moment with Mary, come to that. Most of the people I see shopping on Sunday morning have that peaceful, dreamy expression on their faces that I know is on ours. That is our Sunday ritual.Now, I am in a different country, with a different woman by my side. But I feel as if I am in more than just a different country; I am in another world, a world where faith and prayer are instinctive and universal, where not to pray, not to be able to pray, is an affliction worse than blindness, where disconnection from God is worse than losing a limb.”

“Then in a moment, in that vast space of rocks and sky and scorching sun, I understood that he had not meant religious faith, not exactly. He was not urging me to become a Muslim or to believe in one interpretation of God rather than another. He knew me for what I was, an old, cold, cautious scientist. That was what I was then. And he was simply pointing out to me the first step to take. The word he had used was faith, but what he meant was belief. The first step was simple: it was to believe in belief itself. I had just taken that step. At long last I understood.I had belief. I did not know, or for the moment care, what exactly it was I had to believe in. I only knew that belief in something was the first step away from believing in nothing, the first step away from a world which only recognised what it could count, measure, sell or buy. The people here still had that innocent power of belief: not the angry denial of other people’s belief of religious fanatics, but a quiet affirmation. That was what I sensed here, in this land and in this place, which made it so different from home. It was not the clothes, not the language, not the customs, not the sense of being in another century. It was none of these. It was the pervading presence of belief.I believed in belief. I didn’t exactly feel as if I was on the road to Damascus, and I was aware I could not think straight because of the power of the sun, but now I knew what the Yemen salmon project was all about. It had already worked its transformation on me. It would do the same for others.”

“Images of people in the Middle East dressing like Westerners, spending like Westerners, that is what the voters watching TV here at home want to see. That is a visible sign that we really are winning the war of ideas—the struggle between consumption and economic growth, and religious tradition and economic stagnation.I thought, why are those children coming onto the streets more and more often? It’s not anything we have done, is it? It’s not any speeches we have made, or countries we have invaded, or new constitutions we have written, or sweets we have handed out to children, or football matches between soldiers and the locals. It’s because they, too, watch TV.They watch TV and see how we live here in the West.They see children their own age driving sports cars. They see teenagers like them, instead of living in monastic frustration until someone arranges their marriages, going out with lots of different girls, or boys. They see them in bed with lots of different girls and boys. They watch them in noisy bars, bottles of lager upended over their mouths, getting happy, enjoying the privilege of getting drunk. They watch them roaring out support or abuse at football matches. They see them getting on and off planes, flying from here to there without restriction and without fear, going on endless holidays, shopping, lying in the sun. Especially, they see them shopping: buying clothes and PlayStations, buying iPods, video phones, laptops, watches, digital cameras, shoes, trainers, baseball caps. Spending money, of which there is always an unlimited supply, in bars and restaurants, hotels and cinemas. These children of the West are always spending. They are always restless, happy and with unlimited access to cash.I realised, with a flash of insight, that this was what was bringing these Middle Eastern children out on the streets. I realised that they just wanted to be like us. Those children don’t want to have to go to the mosque five times a day when they could be hanging out with their friends by a bus shelter, by a phone booth or in a bar. They don’t want their families to tell them who they can and can’t marry. They might very well not want to marry at all and just have a series of partners. I mean, that’s what a lot of people do. It is no secret, after that serial in the Daily Mail, that that is what I do. I don’t necessarily need the commitment. Why should they not have the same choices as me? They want the freedom to fly off for their holidays on easy Jet. I know some will say that what a lot of them want is just one square meal a day or the chance of a drink of clean water, but on the whole the poor aren’t the ones on the street and would not be my target audience. They aren’t going to change anything, otherwise why are they so poor? The ones who come out on the streets are the ones who have TVs. They’ve seen how we live, and they want to spend.”

“I know who I was, I can tell you who I may have been, but I am, now, only in this line of words I write. I'm not sure of the nature of my existence, and wonder to find myself writing.”

“What is love of one's country; is it hate of one's uncountry? Then it's not a good thing. Is it simply self-love? That's a good thing, but one musn't make a virtue of it, or a profession...Insofar as I love life, I love [my country], but that sort of love does not have a boundary-line of hate. And beyond that, I am ignorant, I hope.”
