Morality is for everybody, and this means that the views of more than one person are needed to create it. That was what made the modern morality, with its emphasis on individuals and the working out of an individual position, so weak. If you gave people the chance to work out their morality, then they would work out the version which was easiest for them and which allowed them to do what suited them for as much of the time as possible. That, in Mma Ramotswe's view, was simple selfishness, whatever grand name one gave to it.
