We discussed Mohism.  It was unsurprising to discover that Chairman Mao found inspiration in the writings of Mozi.  Mozi seems to be a practical man rather than a courtier, and he thought that less should be spent on lavish concerts and funerals and those resources directed to the ordinary people.  He was anti- war, but studied defence against aggression.  The doctrine of impartial care - that we should care for everybody equally - has its problems and certainly challenged Confucius’ teaching of respect and care for family members.  Mozi claimed that good behaviour was decreed by heaven - and ghosts would be your conscience - but Mohists derived practical guidelines to good behaviour.  These had to start from the teaching of the sages, supported by evidence that they worked, and most importantly by the benefit they offered.  Mohists were primarily consequentialists.  Knowledge meant being able to understand the rules - to judge whether an act was good or bad, because then the rule was demonstrably understood.  Our researches included a short video introduction here, and there is a series of episodes (24 to 32) of Peter Adamson’s “Philosophy without any Gaps” starting here, and then there is a Stanford encyclopaedia of philosophy article here.
