One of the reasons people might be fallible, why we might fail to do what we try to do isignorance, that we have a limited understanding of the laws of the world - the physical laws that govern the world and of all the particulars of the world upon which those laws work. And then there's ineptitude, meaning that the knowledge is available, but individuals fail to apply it correctly. The third source is "necessary fallibility." That is, we're never going to be omniscient, there is some knowledge that we will simply never achieve, and there are limits to what we will be able to do.

No travel ban or quarantine will seal a country completely. Even if travel could be reduced by eighty per cent-itself a feat-models predict that new transmissions would be delayed only a few weeks. Worse, it would only drive an increase in the number of cases at the source. Health-care workers who have fallen ill would not be able to get out for treatment, and the international health personnel needed to quell the outbreak would no longer be able to go in.

You can't make a recipe for something as complicated as surgery. Instead, you can make a recipe for how to have a team that's prepared for the unexpected.

You know, 97 percent of the time, if you come into a hospital, everything goes well. But three percent of the time, we have major complications.

Once you start to ask patients about their priorities, you discover what they're living for. Once you uncover that, it helps you, as a doctor, decide what to fight for. And when we do that, we often end up identifying limits to the kind of care that people want. One's assumption is that these people are going to live shorter lives, but what we're doing is protecting quality of life. In doing so, you sometimes end up helping people live longer. Certainly, you help people live better days and with more purpose in their lives.

We recruit for attitude and train for skill.

In many ways, the effort to study philosophy was my rebellion away from medicine. I'm the son of two Indian immigrant physicians, so the natural path for me would have been to become a doctor. I ended up doing the master's degree at Oxford in politics, philosophy, and economics while already having a seat in medical school. I was keeping that as my escape hatch. But my hope was that I might become a philosopher or something else entirely.
