Status Updates From Robots and Empire (Robot, #4)

“Since everyone can think of some past injustice to avenge, what you are saying, my friend, is that it is right for the strong to oppress the weak... What I say is that oppression was wrong when we practised it in the past, and that it will be equally wrong when you practise it in the future. We cannot change the past, unfortunately, but we can still decide on what the future shall be.”
