And yet discussing progress in this manner can be a confort. All that you said was true... But what the person you replied said was also true. Two generations since fertilizer or two generations since we locked in Malthusian anarchy[please note I do not espouse Malthusianism]. Three generations since the worst war known to man and three generations that did not experience that kind of war. Glass half full, glass half empty. It's correct to question the myth of unstoppable progress thru which you can just kick your feet up and relax. But equally is it important to keep perspective remember that, yeah, eight generations ago chattel slavery was a bonafide institution and four generations women were unfranchised. Things get better and they get worse. We make progress and it is wiped away. We still keep trying.
