I hate to see suffering in the world - whether it be a westerner bereft of his family in tragic circumstances, or a third world father realisng that his children will die becasue he cannot feed them. In both cases I will cry over their situations and want to make the world a place with less suffering.
But what is less suffering? If more people suffer, does this mean that suffering is greater? Suffering is individual and personal. No one person can suffer any more than the sum of their experiences. Surely the total suffering in the world is simply the maximum of all the individual suffering, not the sum of the suffering?
If I manage to resolve the suffering of all but one of the population, have I actually achieved anything? I will still cry over the one left...
