Let me suggest the three laws, modified for human consumption:
1) thou shalt not override the free-will of another, or thru inaction, allow a third party to override the free will of another
2) thou shalt help those less fortunate than yourself, to the best of your ability and in a sustainable way, unless it conflicts with the 1st law
3) thou shalt have fun and do whatever you want, unless it conflicts with the first or second law
It would be fun to discuss the ramifications of this. for examples of what shakes out: no wars, no "illegal" drugs, no banksters, no monsanto, no monopolies or or oligopolies, marriage equality, no slavery/trafficking, no secret backroom deals, etc etc.
i fully expect some to vociferously disagree with this, and i think that's part of the fun. but i think we could go a long way toward a more civilized society by seriously considering these ideals.
