Slavery was abolished largely before the industrial revolution.
Food supply improvement, Indoor plumbing, and air conditioning are all great but are not in any way indicative of moral progress.
Genocide, suicide, crime, abortion, oppression, and the culture of death in general are all much more prevalent in the last 125 years than ever before.
At the very least, I hope you can understand why someone may think that scientific progress is not related to moral progress, and that scientific error in no way implies moral error. You may not agree, but you're a long way from establishing a tie between the two, despite popular opinion to the contrary.
Almost every statement you just wrote is arguable. I'm not sure I agree with any of it.
If you include the world wars, it's hard to argue...
I fully disagree.
Hard to argue the math. Bloody, violent century.
Did most of the world usually try to step in when genocide and empire building started in a part of the world? In Europe? Do you think it's more moral to go to war, or let that happen?
People lined up on two sides and slaughtered each other in trenches for years and years due to politics. In WW2, America nuked two cities. There have been countless genocides, wars and atrocities in the past 100+ years. Hard to argue that, but it appears you are doing so. Do you think nuking two cities is "moral"?
Depends on the decision you're making.
Is it to either nuke two cities or face the very real possibility that you'll need to systematically slaughter an entire nation in order to win a war, also costing thousands and thousands of your own soldiers' lives? There's a big moral decision there, and it's a lot grayer than you seem to think it is. That's the very real scenario the U.S. was in. Japan had sworn to never surrender, to the last resident.
At any rate, on genocide: Genocide wasn't new in the 20th century. There was a new
word for it - because genocide was coined in the 40s. That in itself represents a moral leap forward - the recognition that the systematic wiping out of an entire population based on nationality, religion, race, or ethnicity is a crime against humanity. Genocide has been happening for millenia. In fact, at first, that was just called "war." Because people were fully separated along those lines.
But let's compare pre-WWI to post-WWI, since that seems to be the period you want to talk about
Yes, there were many examples of attempted genocide post-WWI. Probably the most widespread (and I'm not by any means able to speak on all of them, but I believe that the two with the most deaths) were the Holocaust instituted by the Nazis and the Holodomor in the Soviet countries, primarily Ukraine. Together, those two totalled roughly 10 million deaths, based on the numbers I'm aware of. There may be better numbers - I'm open to hearing about them. That's a whole lot of people. And international courts were convened to bring charges against the perpetrators.
It's probably not as many as the Belgians killed in the Congo beginning in 1885. Estimates vary, but it's pretty clear that at least 10 million Congolese were slaughtered. Most people haven't even heard of this. No charges were brought.
The indigenous population of the Americas is estimated at about 50 million people before the Europeans showed up. That number was at about 2 million when the 20th century started. No charges have been brought.
The indigenous people of Australia lost something like 95% of their population between the 1780s and the beginning of the 20th century. No charges have been brought.
Yes, people do bad things. But we as a society have decided this is wrong and we will bring people to whatever justice we can for the crime of genocide.
We didn't even recognize there was anything wrong with it as a society or even give it a name until the 1940s.
