One necessary part of a movement for global health equity is a cohort of medical professionals dedicated to serving the poor. In Paul's commencement speeches at medical schools, many of which appear in the second section, he asks new doctors to keep in mind the big picture: all that lies beyond cutting - edge laboratories and clinical facilities.
The upper echelons of health research and practice in the wealthy world embody the promise of modern medicine. But without an equity plan, that promise remains unrealised to billions of people around the world - the very people who shoulder the lion's share of the burden of disease.
Paul isn't calling for everyone to drop what they're doing and start working on the front lines of global health. He's always been a stalwart cheerleader for scientific innovation, and commends all those who devote their lives to pushing the frontier.
He just asks that every member of the medical professions, broadly defined, remember that even the greatest therapeutic or diagnostic breakthroughs will mean little unless they reach the people they were designed to help.
