Again, conventional Catholicism does not much appeal to me.

I recommend the same therapies for all humans with HIV. There is no reason to believe that physiologic responses to therapy will vary across lines of class, culture, race or nationality.

Civil and political rights are critical, but not often the real problem for the destitute sick. My patients in Haiti can now vote but they can't get medical care or clean water.

So I can't show you how, exactly, health care is a basic human right. But what I can argue is that no one should have to die of a disease that is treatable.

I've been impressed, over the last 15 years, with how often the somewhat conspiratorial comments of Haitian villagers have been proven to be correct when the historical record is probed carefully.

The thing about rights is that in the end you can't prove what should be considered a right.

At the same time, it is obvious that clinicians in Haiti are faced with different, and, in fact, greater, challenges when attempting to treat complications of HIV disease.

Since I do not believe that there should be different recommendations for people living in the Bronx and people living in Manhattan, I am uncomfortable making different recommendations for my patients in Boston and in Haiti.

We've taken on the major health problems of the poorest - tuberculosis, maternal mortality, AIDS, malaria - in four countries. We've scored some victories in the sense that we've cured or treated thousands and changed the discourse about what is possible.

I would say that, intellectually, Catholicism had no more impact on me than did social theory.

I mean we grew up in a TB bus and I became a TB doctor.

But as for activism, my parents did what they could, given the constraints, but were never involved in the causes I think of when I think of activists.

Again, conventional Catholicism does not much appeal to me.

But if you're asking my opinion, I would argue that a social justice approach should be central to medicine and utilized to be central to public health. This could be very simple: the well should take care of the sick.

In fact, it seems to me that making strategic alliances across national borders in order to treat HIV among the world's poor is one of the last great hopes of solidarity across a widening divide.

The human rights community has focused very narrowly on political and civil rights for many decades, and with reason, but now we have to ask how can we broaden the view.

Anywhere you have extreme poverty and no national health insurance, no promise of health care regardless of social standing, that's where you see the sharp limitations of market-based health care.

The poorest parts of the world are by and large the places in which one can best view the worst of medicine and not because doctors in these countries have different ideas about what constitutes modern medicine. It's the system and its limitations that are to blame.

I think we will see better vaccines within the next 15 years, but I'm not a scientist and am focused on the short-term - what will happen in the interim.

I'm not an austere person.

It is clear that the pharmaceutical industry is not, by any stretch of the imagination, doing enough to ensure that the poor have access to adequate medical care.

I critique market-based medicine not because I haven't seen its heights but because I've seen its depths.

The only way to do the human rights thing is to do the right thing medically.

For me, an area of moral clarity is: you're in front of someone who's suffering and you have the tools at your disposal to alleviate that suffering or even eradicate it, and you act.

I'm one of six kids, and the eight of us lived for over a decade in either a bus or a boat.

Everybody should be interested in access to primary and secondary education for everybody.

I can't think of a better model for Haiti rebuilding than Rwanda.

I mean, everybody should have access to medical care. And, you know, it shouldn't be such a big deal.

I've been working in Haiti 28 years - I thought I'd sort of seen it... I've gone through a number of coups, the storms of 2008, I thought, you know, that I'd seen things as bad as they were going to get, and I was wrong.

If any country was a mine-shaft canary for the reintroduction of cholera, it was Haiti - and we knew it. And in retrospect, more should have been done to prepare for cholera... which can spread like wildfire in Haiti... This was a big rebuke to all of us working in public health and health care in Haiti.

If you look at people who seek a lot of care in American cities for multiple illnesses, it's usually people with a number of overwhelming illnesses and a lot of social problems, like housing instability, unemployment, lack of insurance, lack of housing, or just bad housing.

The biggest public health challenge is rebuilding health systems. In other words, if you look at cholera or maternal mortality or tuberculosis in Haiti, they're major problems in Haiti, but the biggest problem is rebuilding systems.

The essence of global health equity is the idea that something so precious as health might be viewed as a right.

We have to design a health delivery system by actually talking to people and asking, 'What would make this service better for you?' As soon as you start asking, you get a flood of answers.

What the American public thinks is very important to the future of global health. Many people are moved by the idea that there is unnecessary suffering in the world, and we could do a lot to stop it. We have the technologies necessary to stop most of the suffering.

You can't have public health without a public health system. We just don't want to be part of a mindless competition for resources. We want to build back capacity in the system.

You can't have public health without working with the public sector. You can't have public education without working with the public sector in education.

If access to health care is considered a human right, who is considered human enough to have that right?

In a world riven by inequity, medicine could be viewed as social justice work.

Equity is the only acceptable goal.

When the problems in Northern Ireland started, it was not a question of Protestantism or Catholicism, because the Catholic church was the only church at that time-it was a nationalist conflict.

Catholicism is not a soothing religion. It's a painful religion. We're all gluttons for punishment.

If I were going to convert to any religion I would probably choose Catholicism because it at least has female saints and the Virgin Mary.

I suppose you could sum up the religious aspects of my boyhood by saying it was a time of life when I was taught the difference between right and wrong as it specifically applied to Catholicism.

Well, I think that Catholicism's basic foundation of faith is personal conscience. I think it's between you and God, not you and the Church.

I would say that, intellectually, Catholicism had no more impact on me than did social theory.

Catholicism is a wide tent in terms of political and legal positions. We could have nine Catholics on the Supreme Court and a great deal of diversity toward the law.

Again, conventional Catholicism does not much appeal to me.

In a way Australia is like Catholicism. The company is sometimes questionable and the landscape is grotesque. But you always come back.
