The nature of the infant is not just a new permutation-and-combination of elements contained in the natures of the parents. There is in the nature of the infant that which is utterly unknown in the natures of the parents.
Children start out loving their parents, but as they grow older and discover their parents are human, they become judgmental. And sometimes, when they mature, they forgive their parents, especially when they discover they are also human.
The honour of parents is a fair and noble treasure to their posterity, but to have the use of a treasure of wealth and honour, and to leave none to your successors, because you have neither money nor reputation of your own, is alike base and dishonourable.
Future generations may well have occasion to ask themselves, "What were our parents thinking? Why didn't they wake up when they had a chance?" We have to hear that question from them, now.
