“[I]t is a mistake to suppose that the moral views of effective altruists can be rejected on the ground that they are more demanding than people now and in the past have thought that morality could be. It may well turn out that future people will view the failure of affluent people to take individual action to save the lives of people in impoverished areas in much the way we now look back on the drivers of slaves, who were also acting in conformity with ‘the view of most people’ at the time.”
