After readinf some essay on the nature of human fallibility, I was very aware that we are the recipients of a huge amount of discovery over the last century. Medicine exemplifies this. And that has transitioned us from a world in which people's lives were mostly governed by ignorance to one that's constrained by ineptitude. A century ago, we didn't know, for instance, what diseases afflicted us, what their nature really was, or what to do about them. And that has changed.

I think the extreme complexity of medicine has become more than an individual clinician can handle. But not more than teams of clinicians can handle.

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.

Better is possible. It does not take genius. It takes diligence. It takes moral clarity. It takes ingenuity. And above all, it takes a willingness to try.

I talked to over two hundred patients and family members about their experiences with aging, serious illnesses, and the big unfixables. But I also spoke with scores of physicians, and especially geriatricians, palliative care doctors, hospice nurses, and nursing home workers. The biggest thing I found was that when these clinicians were at their best, they were recognizing that people had priorities besides merely living longer. The most important and reliable way that we can understand what people's priorities are, besides just living longer, is to simply ask. And we don't ask.

What is the alternative to understanding the complexity of the world?

What is needed, however, isn't just that people working together be nice to each other. It is discipline. Discipline is hard--harder than trustworthiness and skill and perhaps even than selflessness. We are by nature flawed and inconstant creatures. We can't even keep from snacking between meals. We are not built for discipline. We are built for novelty and excitement, not for careful attention to detail. Discipline is something we have to work at.
