I'm not sure you actually realise the implications of your argument of the inevitability of harmony.
I've not seen an indication that you understood the argument. You've offered one distortion of it after another.
So if there was a nuclear war, do you consider that global harmony would still be still inevitable?
yes. I don't think human nature would be changed in any way.
Are you confident that 50 million people would not be forcefully kept out? Do you consider it impossible that such an event could lead to extremist governments gaining power in the West?
If I had claimed that humanity's moral progress could be graphed as a straight line upward, your hypotheticals might be relevant, I'm not sure. But I didn't make that claim.
My claim is that, long term, our species is making moral progress and I don't see any hypothetical event that you might create that will change our basic nature.
You keep saying people redefine things. When someone uses backslide to mean backslide you somehow consider it mendacious.
"Backslide" refers to a slide back from an achieved level. Does that help?
Pinker's use of stats is terribly flawed as I explained in another thread. The 'declining trend of violence' would also be statistically reversed in a nuclear war.
The issue is the level of violence in human nature. Please explain how advanced weapons changes that level. Is a man with a bow and arrow morally better than one with an automatic rifle?
But even if he is 100% correct, he doesn't make your argument. He simply believes it is probable there will be a trend towards reduced violence and increased cooperation. He doesn't predict 'global harmony' and he doesn't consider it 'inevitable'.
Will you quote me, please? Where did I claim that Pinker supported my entire argument?
