The changes associated with the Renaissance, Reformation and Enlightenment moved the seat of authority from princes and bishops to the individual and made the application of rationality the measure of believability. This paper argues that the current period of socio-political and moral upheaval, triggered by disruptive technology, anger about corruption and distrust of intellectual elites, is resulting in a move beyond linear and reductionist thinking to an approach characterised by complexity, and from rationalism to relational thinking. Some implications for public morality are identified and discussed.
