Cooperation between the nations of the world to benefit the quality of life for the citizens of the global community.
That already happens.
Does 'global harmony' involve no more wars and all countries operating in the 'global interest' and not in the national interest?
If I did, you should be able to quote an example or two.
You claimed that the Khmer Rouge killing 1/3 of the population of Cambodia didn't constitute moral backsliding because:
"In order to backslide, the problem has to first be under control, but not necessarily completely eliminated. We're never had warlike aggression under control."
Cambodia seemed to have the genocide problem under control in the pre KR era.
Afghanistan used to be a place that hippies went to to smoke hash and wear ridiculous knitwear. Now they would likely be kidnapped and possibly beheaded for doing so.
I quoted him as an authority on the decline of violence only. I have no idea what he thinks on any other topic, nor do I care.
It's the same topic, what does the historical decline of violence tell us going forward?
So Pinker is credible when he is discussing the decline of violence, but when he warns that his data should in no way be interpreted as standing for the inevitability of global harmony he becomes one of these irrational pessimist that are stone cold wrong as they ignores all of the evidence that you have compiled to prove that it is?
Pinker is the apogee of self-congratulatory optimistic Enlightenment fanboyism and selective history, and even he thinks you are out of your mind wrong on the issue.
While you will disagree, you seem to have a fundamentalist mindset on this issue.
A fundamentalist believes their ideological worldview reprints the paradigm for the rest of humanity. They don't accept that their worldview is a product of their cultural environment, but instead that it reflects a universal truth intrinsic to our existence
From this they cherry pick and distort information to feed their confirmation bias and remove any cognitive dissonance.
The mere suggestion that a nuclear WW3 could drive highly problematic for the prospects of 'global harmony' is simply dismissed as 'Hollywood fantasy'. The fragility of a technologically complex, highly interconnected world is simply brushed under the carpet. In the last 100,000 years of 'human nature', 99,700 saw minimal moral improvement (and that's giving the last 300 some major benefit of the doubt), yet that last period is seen as defining who we 'really' are and represents the only possibility for the future.
Another aspect of a fundamentalist mindset is total lack of ability to empathise with others who may view the situation differently. Such people are simply deluded fools wilfully blind to the truth. The incompatible aspects of their cultures are deemed harmful anachronisms to be eradicated so we can make way for the new order.
You acknowledged in another thread that some recalcitrant 'foolish' people who weren't on board with your Brave New World might have to be forced into getting with the program. You also refused to accept that people from diverse cultures might have problems accepting significant parts of your paradigm as you believe your views transcended culture (when they are really an obvious product of it).
A fundamentalist is blessed with great certainty about what the future holds and cannot conceive of the possibility that their confidence may be based purely on thin air. The fundamentalist is adamant though that this confidence is based on the most solid of foundations that any reasonable person operating with a clear mind and free from bias would have to agree with.
Yor argument is based on choosing some anecdotal and statistical evidence from the past and turning it into an iron law about the future in a most unscientific manner that seems to be based on little but blind faith. It seems to lack the imagination to perceive of any challenges or obstacles that could prevent this from happening.
Finally the fundamentalist beliefs that their ideology is practical, even though non-fundamentalists see it as utopian.
There can be few things more utopian than inevitable global harmony.
We'll never agree on this though.
