Asked about the need to identify what would be required of a health care system in order to secure for each person all beneficial follow-on medical interventions, Colgrove noted that the question had both an empirical component and an ethical component, the latter derived from a sense of “what it is that is due to people” according to a theory of justice. Whether the empirical discussion should precede the ethical discussion, or, as Colgrove suggested, the ethical discussion should come first, the reality, he agreed, was that both of those discussions are being left out of current political debate.
