Freedom is productive and generative. Slavery is not. Authority in a just society intervenes, therefore, only when the subject cannot, even upon completion of the act, perceive the harm done to oneself or when one is inhibiting the freedom of others.
Immanuel Kant offered a morality based on honor. Jeremy Bentham and then John Stuart Mill offered an advantage based morality. Not believing in honor, we prefer the Utilitarian approach. The trouble is, there’s no honor in it.
Our hatred of humanity is not emotionally driven, but it is passive-aggressive. We are passive in regard to cultivating the faculties that make us free humans; we are aggressive in regard to cultivating the tools that make us powerful. The quest for the blood diamond is our master.
