"the Mohists were against prolonged funeral procedures. And one of the arguments in response was, "But these rituals are followed by gentlemen. If you're right that this is unjustified, why is it that these people we admire, people with high social status, are so dedicated to it?"
And the Mohist
response is that that confuses custom with morality.
"We're saying it's immoral, & you're saying it's a custom - & customs can be immoral, and therefore should be changed."
