Stephen Hawking: Biggest Human Failing Is Aggression
hypnosec writes: Aggression is the human failing that celebrity scientist Stephen Hawking would most like to correct, as it holds the potential to destroy human civilization. Hawking expressed his views while escorting Adaeze Uyanwah — London's Official Guest of Honor — around London's Science Museum. Uyanwah asked Hawking what human shortcomings he would alter, and which virtues he would enhance if this was possible. He replied, "The human failing I would most like to correct is aggression. It may have had survival advantage in caveman days, to get more food, territory, or partner with whom to reproduce, but now it threatens to destroy us all. A major nuclear war would be the end of civilization, and maybe the end of the human race."
Non-aggression is a principle of ethics.
From the Wikipedia:
Like all ethics principles there are edge cases that create long, contentious discussions. But the basic idea is that you can use force to defend yourself (or others) against aggression as defined above. Otherwise, you leave everyone else alone.
Strangely, "We don't start things, but if you do we'll finish it and you won't like that." is probably an accurate synopsis of self-defense for a proponent of the NAP.
