Our common lot: Ethicist Daniel Callahan asks why it is that the U.S. is the only developed country that doesn't provide universal health-care insurance. One reason is that Americans don't have a strong tradition of thinking about the common good. "Suffering, disease, and death are our common lot," argues Callahan. "They ought to be dealt with as our common problem . . . in the recognition that we all have bodies that go awry and fail" (Commonweal, October 9).
