One of the notable things about discussing the interpretation of quantum mechanics with physicists and with philosophers is that it is the physicists who propose philosophically radical ways of interpreting a theory, and the philosophers who propose changing the physics. One might reasonably doubt that the advocates or either strategy are always fully aware of its true difficulty.

[T]here can be no way of justifying the substantive assumption that all forms of altruism, solidarity and sacrifice really are ultra-subtle forms of self-interest, except by the trivializing gambit of arguing that people have concern for others because they want to avoid being distressed by their distress. And even this gambit […] is open to the objection that rational distress-minimizers could often use more efficient means than helping others.
