“When I stepped onto the bridge over the Iowa River and stood looking out across the water, I knew I was home. I was wrong about that, as it turns out. And I know now that my certainty was based on a series of troubling misconceptions, but it would be years before I would lose the comfort that certainty gave me.”

“One of the shortcomings of our medical system is that doctors have very little time with their patients.”

“I think that people's resistance to vaccination isn't going to disappear until we address some of the nonmedical reasons for that resistance and people's discomfort and distrust of the government. That's bigger than what most medical professionals can handle.”

“And when comfort is what we want, one of the most powerful tonics alternative medicine offers is the word 'natural.' This word implies a medicine untroubled by human limitations, contrived wholly by nature or God or perhaps intelligent design. What 'natural' has come to mean to us in the context of medicine is 'pure' and 'safe' and 'benign'. But the use of 'natural' as a synonym for 'good' is almost certainly a product of our profound alienation from the natural world.”

“I know you're on my side," an immunologist once remarked to me as we discussed the politics of vaccination. I did not agree with him, but only because I was uncomfortable with both sides, as I had seen them delineated. The debate over vaccination tends to be described with what the philosopher of science Donna Haraway would call "troubling dualisms." These dualisms pit science against nature, public against private, truth against imagination, self against other, thought against emotion, and man against woman.”

“I felt sick with hatred then for my own people. If you had asked me why I hated them, I might have said that I hated them for being so loud and for being so drunk. But now I believe I hated them for suddenly being my people, not just other people. In the United States, it is very easy for me to forget that the people around me are my people. It is easy, with all our divisions, to think of myself as an outsider in my own country. I have been taught, and I have learned well, I realize now, to think of myself as distinctly different from other white folks - more educated, more articulate, less crude. But in Mexico these distinctions became as meaningless to me as they should have always been.”

“When I stepped onto the bridge over the Iowa River and stood looking out across the water, I knew I was home. I was wrong about that, as it turns out. And I know now that my certainty was based on a series of troubling misconceptions, but it would be years before I would lose the comfort that certainty gave me.”

“I was only going to stay six months. I stayed three years, and I never stopped thinking about leaving. But when I left, I left my entire life behind. I have to explain to you why I no longer live in New York, but first I have to explain to myself why I stayed so long.”

“If by years of patient suffering, God can manage to take the harshness out of my voice, then the time has been well-spent.”

“One of the paradoxes of our time is that the War on Terror has served mainly to reinforce a collective belief that maintaining the right amount of fear and suspicion will earn one safety. Fear is promoted by the government as a kind of policy. Fear is accepted, even among the best-educated people in this country, even among the professors with whom I work, as a kind of intelligence. And inspiring fear in others is often seen as neighborly and kindly, instead of being regarded as what my cousin recognized it for - a violence.”
