Tom Robinson is now officialy my coolest reader. He commented as follows WRT inverse theory:
To put in real propositions, B states 0+1=1. A states that we shouldn't murder Jews. I propose A and B are consistent. C states that we should murder Jews. I propose A and C are inconsistent. I conclude that B and C are inconsistent -- that wanting to murder Jews and doing math right contradict. This works with any form of being evil and math.
It is hard to see what the inverse worldview looks like. It is foreign to us, and most of its twisted logic beyond our worst nightmares. We get glimpses in the bad people of our world, but they are nowhere near the limits of evil.
Good people are succesful and flourish. Bad people, therefore, are unsucessful and do not flourish objectively, even if they think they do (or perhaps they think flourishing is bad, and think they do not flourish). I believe, in the limit, evil people would be unable to eat meals, or otherwise manage to even stay alive.
My explanation of why the bad people of our world manage to eat, and even manage to use creativity to plan nasty attacks, is that they are inconsistent. Much of their worldviews are true. They use the true bits to function. But they also have a significant, inverse portion, from which they take many of their goals and motives.
Notably, it is this inconsistent combination that allows them to be truly dangerious. An evil person who uses some true ideas to get what he wants is more threatening than an evil person who's own evil has rendered him impotent.
